A Wave To Watch

3:52PM

Low pressure moving away in eastern Canada and a small high pressure area trying to build in will bring dry, breezy, and cooler weather through Thursday. A wave of low pressure passing south of the region later Friday to early Saturday will bring some cloudiness and a chance of rain mainly for RI and southern MA. High pressure builds in again later in the weekend then offshore early next week with fair weather, starting cool then followed by a warming trend.

Rain Blast Won’t Last

5:50PM

The focus of this update, even though it will contain a full forecast, is the potential severe weather event for Wednesday morning. I will keep it short and to the point. As broad low pressure passes north of the region across southern Canada and a strengthening second low passes northwest of southern New England, its attendant cold front will swing through the region from west to east in the early to mid morning hours of Wednesday, bringing an area of rain including some embedded heavy showers and thunderstorms.

Time-frame: 3AM-9AM for entire event, though the heaviest rain and strongest wind will be relatively short-lived for any given area. Areas west of Boston from western into central MA and adjacent CT/VT/southwestern NH will see activity in the 3AM-6AM window of time, while eastern MA including the Boston area as well as RI and southeastern NH gets it closer to the 6AM-7AM time. Cape Cod and the Islands will be last to see the activity arrive and depart.

Severe? The risk of torrential rain for at least a brief period of time as high. This would disrupt travel and cause localized flooding. The risk of strong and gusty winds of the straight-line variety is moderate. The risk of a brief tornado is low but cannot be ruled out completely.

What happens after? Once the action is out of here Wednesday morning, the rest of the day will feature sun and passing clouds, drying air, and a gusty breeze, though it will still be mild through the daylight hours as a secondary trough, behind which is the cooler air, will not arrive until later in the day.

Between broad low pressure in eastern Canada and a small high pressure area to the south will be a gusty and cool westerly wind but a nice day for Thursday. Low pressure passing south of the region later Friday to early Saturday will bring some cloudiness and a threat of some rain to at least southern MA and RI. Not sure how far north this gets yet. But I do think it gets out of here for later Saturday and Sunday which will be dominated by high pressure and nice Autumn weather.

Still looks like a warm-up early next week, though the tropical threat looks less. More on this later.

SOUTHEASTERN NEW ENGLAND FORECAST
EVENING: Lots of clouds, partial moonshine as it rises in the east. A shower far west to northwest of Boston. Temperatures in the 60s. Wind S 10-20 MPH.
OVERNIGHT: Heavier clouds arrive from southwest to northeast. Rain and embedded thunderstorms arriving west to east after 2AM, heaviest activity west of Boston after 3AM and Boston area northward and southward by the 6AM hour (see details above). Lows around 60. Wind S to SW 5-15 MPH, higher gusts.
WEDNESDAY: Cloudy start with rain and embedded thunderstorms ending in eastern areas by mid morning. Sunshine and passing clouds mid morning on though lingering clouds/showers Cape Cod mid morning. Highs 65-70. Wind SW 10-20 MPH, strongest gusts, shifting to W.
WEDNESDAY NIGHT: Mostly clear. Lows in the 40s. Wind W 5-15 MPH.
THURSDAY: Mostly sunny. Highs around 60. Wind W 10-20 MPH.

Small Surprise In A Big Package

6:08PM

SOUTHEASTERN NEW ENGLAND DISCUSSION…
As a large upper level low pressure continues to spin in east central Canada and the north central USA through the middle of the week, it will send some action our way in the form of developing surface low pressure over the Ohio Valley Tuesday. This low will intensify fairly quickly and move northeastward into the St. Lawrence Valley by Tuesday night then northward deeper into Canada by Wednesday. Its broadening circulation will first send a batch of mild and more humid air into southern New England on Tuesday as a weak warm front moves through during the morning and midday. A few showers may occur with this, but otherwise it will just send lots of clouds through the region. A few bands of showers will form well northwest of Boston during the day but it looks like this activity will never make it further east than southwestern NH and north central MA before it dissipates. The main push of wet weather that is destined for southeastern New England is going to be from an occluded front trailing from the parent low pressure area. This front will swing through the region in the pre-dawn to shortly-after-dawn hours of Wednesday, and will be accompanied by a band of rain and possible thunderstorms, and potentially strong wind gusts. This will be watched as it gets closer to occurring. Once this area crosses, it will be followed by gusty west winds, drying but still mild air during the day, a mix of clouds and sun, and a slight risk of a passing additional shower. By Wednesday evening, it will turn significantly cooler behind a trailing trough. Cool and dry weather is expected Thursday along with a gusty breeze as the broad low pressure area continues to push across southeastern Canada. Friday, a small wave of low pressure will bring more cloudiness and the chance for some light rain, depending on its track. This should move right along and evacuate the region in time for high pressure to move in for the weekend, which looks nice. By the start of next week, this high should be shifting offshore and a warm-up will be underway.

SOUTHEASTERN NEW ENGLAND FORECAST…
TONIGHT: Partly to mostly cloudy. Lows in the 50s. Wind S 10-20 MPH.
TUESDAY: Variably cloudy. Isolated showers through midday. Chance of additional showers far northwest of Boston in the afternoon. Highs upper 60s to lower 70s. Wind S 10-20 MPH with higher gusts.
TUESDAY NIGHT: Variably cloudy. Lows around 60. Wind S 10-20 MPH with higher gusts.
WEDNESDAY: Mostly cloudy with a band of showers and possible thunderstorms west to east early morning, perhaps to mid morning Cape Cod, then mixed sun and clouds with a slight chance of passing showers. Highs around 70. Wind SW 10-20 MPH with higher gusts, possibly strong gusts with passage of rain band, shifting to W 15-30 MPH.
THURSDAY: Sunny to partly cloudy. Lows in the 40s. Highs around 60.
FRIDAY: Cloudy. Chance of light rain. Lows in the 40s. Highs in the 50s.
SATURDAY: Clouds linger southeast, sunnier northwest. Lows in the 40s. Highs in the 60s.

MONDAY: Partly cloudy. Lows around 50. Highs around 70.

The Week Ahead

6:23PM

SNE DISCUSSION…
Some media will probably still try to play up the “big vortex” dominating the weather in the US this coming week. While it’s true that a fairly strong closed-off low pressure area will be the rule, and some of its weather includes early frozen precipitation and cold air (mainly central USA), what it will serve to do for the Northeast is keep the pattern on the mild side, with 2 disturbances passing by, one early Wednesday and another late Friday. Shower threats will exist in advance of and with the passage of each of these (late Tuesday to early Wednesday and again during Friday and Friday night, based on current timing). By the weekend, the closed low will have weakened and lifted northeastward into Canada, being replaced by a strong west-to-east jet stream. By early the following week, things may get a little more interesting once again as the overall pattern will be mild and a little wetter, and with a potential threat from the tropics. Long way off – no worries now. That will be addressed in due time.

SNE FORECAST…
TONIGHT: Clear. Patchy frost far inland valleys. Lows in the 30s inland valleys, 40s elsewhere but around 50 immediate shore and urban areas. Wind W dropping to under 10 MPH, calm in some valleys.
MONDAY: Sunny. Highs in the 60s to near 70. Wind SW 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Lows in the 50s. Wind S 5-15 MPH.
TUESDAY: Variably cloudy. Slight chance of showers mainly far northwest of Boston in the afternoon. Highs from the middle 60s to lower 70s. Wind S 10-20 MPH.
WEDNESDAY: Variably cloudy with scattered showers morning. Partly to mostly sunny afternoon. Lows in the 50s. Highs in the 60s.
THURSDAY: Mostly sunny. Lows in the 40s. Highs in the 60s.
FRIDAY: Mostly cloudy. Showers possible mainly afternoon and night. Lows around 50. Highs in the 60s.
SATURDAY: Partly to mostly sunny. Lows in the 40s. Highs in the 60s.
SUNDAY: Sunny to partly cloudy. Lows in the 40s. Highs in the 60s.

Split Weekend

7:29AM

SOUTHEASTERN NEW ENGLAND DISCUSSION…
No big changes to this forecast other than to slow the timing down of the wet weather system for next week a little. Onshore flow continues today but with sun, especially inland, though ocean clouds win the battle late in the day after flirting with the coastline most of the day. By tonight and Saturday, it’s overcast as low pressure approaches from the west, but its rain will first arrive well to the west and hold off from reaching the eastern areas until late in the day and evening. Some drizzle and areas of fog may occur before that due to low level moisture from the ocean. The cold front from the west clears the whole mess outta here by Sunday morning and Sunday will be a great Fall day. Nice weather with a warming trend for next week as the flow turns southwest. Another front crosses the region Wednesday with showers.

SOUTHEASTERN NEW ENGLAND FORECAST…
TODAY: Sun inland, clouds/sun coast, then clouds advancing inland late. Highs from near 60 coast to near 65 inland. Wind NE up to 10 MPH.
TONIGHT: Cloudy. Areas of fog and drizzle overnight. Lows in the 50s. Wind light E.
SATURDAY: Cloudy. Areas of fog and drizzle. A band of rain arriving from west to east late afternoon into the night with a slight risk of embedded thunderstorms. Highs in the 60s. Wind SE 5-15 MPH increasing to 10-20 MPH with higher gusts late.
SUNDAY: Mostly sunny. Low 50. High 60.
MONDAY: Partly cloudy. Low 45. High 65.
TUESDAY: Partly sunny. Low 55. High 70.
WEDNESDAY: Mostly cloudy. Chance of showers. Low 55. High 65.
THURSDAY: Partly cloudy. Low 45. High 60.

Wetter Is Better

12:05AM

SOUTHEASTERN NEW ENGLAND DISCUSSION…
A few days ago, it looked like “a few showers”. But in reality, for at least parts of southern New England, it evolved into a somewhat beneficial rain, all due to low pressure spinning offshore. It’s not a strong storm, but this interaction of upper level energy, surface low pressure, and moisture has delivered some wet weather, not nearly enough to break the minor to moderate drought but helpful to that end. What would be better is more regular rain events. We’ll have some of that, as the overall pattern is evolving to feature a significant trough of low pressure in the Midwest, putting the East Coast including New England on the east side of it, often in an upper level southwesterly flow, combining moisture from the south with disturbances from the west. One such system will cross the region this coming weekend, with another threat early next week. Right now, the former looks more significant and the latter a little less productive. Though some chilly shots of air will be diving out of Canada into the central US in this upcoming pattern, it’s not a particularly chilly pattern for New England, as cool air masses arriving behind departing low pressure systems are often modified by a long trip over a landmass holding leftover Summer warmth.

SOUTHEASTERN NEW ENGLAND FORECAST…
OVERNIGHT: Overcast. Rain likely. Lows in the 50s. Wind NE to N 10-20 MPH.
THURSDAY: Cloudy with rain becoming spotty and diminishing north to south during the morning. Breaking clouds in the afternoon. Highs in the 60s. Wind N 10-20 MPH.
THURSDAY NIGHT: Clearing. Lows 48-55. Wind N 10-20 MPH.
FRIDAY: Sunshine but increasing high clouds late day. Highs in the 60s. Wind E 5-15 MPH.
SATURDAY: Cloudy. Patchy fog and drizzle with a chance of light rain morning and midday. Showers developing from west to east afternoon and evening. Rain and a chance of thunderstorms at night followed by rapid clearing southwest to northeast overnight. Low 56. High 68.
SUNDAY: Mostly sunny. Low 52. High 65.
MONDAY: Partly cloudy. Low 53. High 71.
TUESDAY: Mostly cloudy. Chance of showers. Low 54. High 67.
WEDNESDAY: Partly cloudy. Low 50. High 65.

Drought Dent

3:54PM

SOUTHEASTERN NEW ENGLAND DISCUSSION…

Post ridge, post cold front, now we have upper level low pressure sitting near to just southeast of New England and an associated surface low as well. Enough moisture is also present to result in periods of rain especially over southern and eastern portions of the WHW forecast area, which has developed today on the final day of September, and will continue tomorrow, the first day of October. By Thursday, low pressure will start to pull away and we’ll trend drier. A sliver of sunshine is expected on Friday between the departing low and another approaching trough from the west. This approaching trough will result in a wet day on Saturday with more beneficial rain possible. These few rain events will put a small dent in the developing drought conditions over southeastern New England, though they won’t even come close to putting an end to it.

After a drying trend Sunday into Monday, another system from the west brings a chance of showers by Tuesday of next week.

SOUTHEASTERN NEW ENGLAND FORECAST…

THROUGH WEDNESDAY: Cloudy with periods of rain and areas of fog. Temperatures ranging from the upper 50s to middle 60s. Wind NE 5-15 MPH increasing to 10-20 MPH with higher gusts especially along the coast by Wednesday afternoon.

WEDNESDAY NIGHT: Rain ends, clouds remain. Lows 50-55. Wind N 10-20 MPH.

THURSDAY: Clouds break but limited sun at best. Highs in the 60s. Wind N 5-15 MPH.

FRIDAY: Mostly sunny. Low 48. High 66.

SATURDAY: Cloudy. PM showers likely. Low 51. High 64.

SUNDAY: Sun & clouds, gusty breeze. Low 48. High 65.

MONDAY: Mostly sunny. Low 50. High 68.

TUESDAY: Mostly cloudy. Showers likely. Low 52. High 66.

Ridge Out

5;46PM

DISCUSSION…

The big high pressure ridge that provided the Summery weekend is now a memory and after the cold front that passed from the north Monday, a more onshore flow will dominate southern New England into midweek before turning more southerly later this week.  Less sun and warmth, more clouds but not much wet weather will be the ruling factors. But by Saturday, a trough of low pressure from the west will bring the first shot at widespread beneficial rain in a while, then continue eastward so that the second half of the weekend should be salvaged for outdoor activities.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Cloudy. Patchy fog and drizzle. Lows 55-60. Wind NE 5-15 MPH.

TUESDAY: Mostly cloudy though a little partial sun is possible west of  Boston during the afternoon. Patchy fog and drizzle. Chance of light rain morning and midday mainly southeast of Boston. Highs in the 60s. Wind NE to E 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Patchy drizzle and fog. Isolated showers possible. Lows 55-60. Wind light E.

WEDNESDAY: Cloudy. Areas of drizzle. Chance of light rain. Highs in the 60s. Wind E to SE.

THURSDAY: Partly sunny. Low 52. High 68.

FRIDAY: Variably cloudy. Low 53. High 66.

SATURDAY: Cloudy. PM showers likely. Low 55. High 66.

SUNDAY: Clearing. Low 51. High 63.

MONDAY: Sunny. Low 48. High 64.

The Week Ahead

5:31PM

DISCUSSION…

The first weekend of Autumn was more like Summer than some of the weekends during the actual Summer, featuring 100% sunshine with high temperatures well into the 80s in many areas. The big ridge of high pressure responsible for this weather is weakening and sinking to the south and will allow a cold front to push through southeastern New England from north to south Monday, bringing some increase in clouds and a turn to cooler air. Then a more onshore flow will be dominant Tuesday through midweek with weak upper level low pressure overhead. This will result in clouds being dominant and temperatures on the cooler side, though not too chilly. By late week, a more southerly flow is expected ahead of an approaching trough from the west, so that by next weekend at least some wet weather is probable.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Mostly clear. Lows 50-55 inland valleys, 55-60 elsewhere. Light wind.

MONDAY: Partly cloudy. Highs 75-80 by early afternoon then cooling later in the day. Wind light variable becoming NE 10-20 MPH from north to south midday and afternoon.

MONDAY NIGHT: Partly to mostly cloudy. Patchy drizzle and fog overnight. Lows 55-60. Wind NE 5-15 MPH.

TUESDAY: Mostly cloudy. Patchy drizzle and fog. Highs 60-65. Wind E 5-15 MPH.

WEDNESDAY: Mostly cloudy. Low 50. High 65.

THURSDAY: Partly sunny. Low 53. High 67.

FRIDAY: Variably cloudy. Low 51. High 66.

SATURDAY: Mostly cloudy. PM showers likely. Low 54. High 66.

SUNDAY: Partly sunny. AM showers possible. Low 50. High 65.

A Weekend High

3:25PM

High pressure at the surface and aloft will sit over New England this weekend, creating clear and warm weather but without humidity – perfect for outdoor activities whether you are indulging in early Autumn traditions or still trying to hang onto Summer as long as you can.

By Monday, we’ll still be in the warm airmass but a cold front will be approaching from the north and may toss some clouds into the region and not allow it to get as warm as the previous 2 days in most locations. This front will settle south of the region for the final day of September and the first day of October (Tuesday-Wednesday) with lots of clouds and somewhat cooler air, though not that chilly. The front is expected to try to creep back northward as a warm front on Thursday but the weather next week is a little suspect with that front trying to come by and possible low pressure trying to form to the southeast of New England while a new high builds north of the region. So the late-week part of the forecast will carry less confidence than usual at this time.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Clear. Lows 40s interior valleys, 50s elsewhere. Wind light variable.

SATURDAY: Sunny. Highs around 80 except 70s coast. Light wind with sea breezes.

SATURDAY NIGHT: Clear. Lows around 50 interior valleys to around 60 coast. Wind light variable.

SUNDAY: Sunny. Highs in the 80s inland and 70s coast. Light wind with sea breezes.

MONDAY: Partly cloudy. Low 55. High 75.

TUESDAY: Partly sunny. Low 50. High 65.

WEDNESDAY: Mostly cloudy. Low 49. High 62.

THURSDAY: Variably cloudy. Low 51. High 66.

FRIDAY: Partly cloudy. Low 55. High 70.

Pardon The Interruption

7:27AM

One interruption today thanks to low pressure moving up from the south, then making a right hook and heading out to sea – but close enough so that clouds dominate and some wet weather moves in as well. Most of the rain will occur along and south of the Mass Pike but some may push a little further north of there later today into tonight. It all pulls away by early Friday and high pressure rebuilds over the region and holds through the weekend into Monday, with a warm-up, feeling a bit like Summer. A cold front from the north arrives by Tuesday putting an end to that particular Summery spell.

FORECAST FOR SOUTHEASTERN  NEW ENGLAND…

TODAY: Cloudy but brighter at times southern NH. Rain arriving in southern MA and RI, may push northward to areas around the Mass Pike later. Highs in the 60s. Wind E 5-15 MPH.

TONIGHT: Cloudy with rain most likely southern half of MA through RI and a chance of a little light rain to the north before ending and clearing toward dawn. Lows in the 50s. Wind E to NE 5-15 MPH.

FRIDAY: Mostly sunny to partly cloudy. Highs 60s coast to lower 70s inland. Wind light NE to N.

SATURDAY & SUNDAY: Clear overnights with patchy fog valley areas. Sunny both days. Lows in the 60s. Highs around 80, cooler coastal areas.

MONDAY: Partly cloudy. Lows around 60. Highs around 80.

TUESDAY: Mostly cloudy. Lows around 50. Highs around 60.

WEDNESDAY: Partly sunny. Lows in the 40s. Highs around 60.

What Was That You Said About Dry Weather For Days?

7:22PM

Ok it may not rain everywhere on Thursday to early Friday, but the threat has presented itself, and is most pronounced for areas south of the Mass Turnpike as it stands now. This is because it looks like developing low pressure down the coast, though not very strong, will be able to drift northeastward just enough to take advantage of a slight weakness in the ridge of high pressure centered just north of New England. So the string of what looked like many days of sunshine will probably be interrupted. There is still some uncertainty as to where the  rain cut-off will be and just how far north it will penetrate. Computer models range from a near-miss to a decent soaking. So with varying scenarios presented to us by our man-made plug-and-chug machines, and just experience that forecasting this type of set-up is difficult, at best, a low-confidence forecast for wet weather over southeastern and eastern areas will follow this, book-ended by a dry forecast for Wednesday and the weekend. In fact, the weekend portion will feature some decent warmth advertised.

Further out but less important right now is a cold front early next week which may end up putting a premature end to the sunny/warm spell.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Few fair-weather clouds vanish northwest sky and a few high clouds south. Lows in the 40s most areas but upper 30s deeper valleys and near 50 in urban locations. Wind light variable.

WEDNESDAY: Sunshine most of the time but some high clouds fanning in from the south while a few lower clouds drift in from the ocean. Highs in the 60s, coolest along the coast. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Increasing clouds. Lows around 50. Wind NE to E 5-15 MPH.

THURSDAY: Cloudy. Chance of rain especially afternoon favoring southern MA and RI. Highs in the 60s. Wind E 5-15 MPH.

FRIDAY: Cloudy start with a chance of rain early favoring eastern MA. Slow clearing later. Low 49. High 68.

SATURDAY: Mostly sunny. Low 44. High 77.

SUNDAY: Mostly sunny. Low 51. High 83.

MONDAY: Sunny. Low 54. High 74.

TUESDAY: Cloudy. Low 50. High 61.

High & Dry

3:25PM

In came the gusty westerly breeze Monday to clear out the air, and now high pressure builds in through Wednesday then sits atop the Northeast for the rest of this week. Low pressure to the south should stay far enough way to only toss some high clouds into the sky at times midweek, and a cold front from the north is likely come through dry late Sunday or early Monday. This is a quiet weather pattern, and a dry one. Slowly, we are building a drought in the region and without significant precipitation this is going to become a more serious issue with time.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: A few stray clouds then clear. Lows in the 40s. Wind W 10-20 MPH with higher gusts early, diminishing to 5-15 MPH.

TUESDAY: Sunny. Highs around 70. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows in the 40s, some upper 30s valleys and lower 50s cities. Wind light NW to N.

WEDNESDAY: Sunshine – few high clouds across the southern sky. Highs in the 60s. Wind N to NE 5-15 MPH.

THURSDAY: Sunshine & high clouds. Low 45. High 70.

FRIDAY: Sunny. Low 48. High 73.

SATURDAY: Sunny. Low 53. High 80.

SUNDAY: Sunny. Low 56. High 82.

MONDAY: Partly cloudy. Low 57. High 78.

The Week Ahead

5:29PM

Low pressure passing east of the southern New England and another passing northwest of the region will be on their way out by early Monday as the cold front from the low to the northwest swings eastward through the region and puts an end to the brief bout of humidity. As upper level low pressure swings through the region Monday there will be a mix of sun and clouds but the air will be mild and less humid. For the remainder of the week, a very large high pressure area will move in and sit over the Northeast, first delivering some cooler air Tuesday and Wednesday followed by a warm-up later in the week.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Isolated showers near Boston early. Isolated showers west of Boston late. Areas of fog. Breaking clouds. Lowering humidity. Lows around 60. Wind variable up to 10 MPH shifting to W.

MONDAY: Sun/cloud mix. Highs around 70. Wind W 10-20 MPH.

MONDAY NIGHT: Clearing. Lows 50-55. Wind W 5-15 MPH.

TUESDAY: Sunny. Highs in the 60s. Wind NW 5-15 MPH.

WEDNESDAY: Sunny. Low 44, cooler valleys. High 65.

THURSDAY: Sunny. Low 47, cooler valleys. High 70.

FRIDAY: Sunny. Low 51, cooler valleys. High 75.

SATURDAY: Sunny. Low 55, cooler valleys. High 82, cooler coast.

SUNDAY: Sunny. Low 57, cooler valleys. High 81, cooler coast.

After The Lows Comes The Big High

12:56PM

2 low pressure areas will move northeastward with southeastern New England right between them (one to the NW, one to the SE) today. In between these is a warm and humid air mass that will be over the region on this last full day of Summer. A few showers will occur in this zone, and perhaps a couple more later tonight as the cold front from the low to the NW swings through. This cold front will clean house and introduce a big high pressure area which will then control the weather for all of next week, which will be dry with temperatures above normal overall, warmest the second half.

FORECAST FOR SOUTHEASTERN NEW ENGLAND…

THIS AFTERNOON: Clouds & sun. Breezy & muggy. Isolated to scattered showers around. Highs from near 70 South Coast to near 80 most inland areas. Wind SE to S 10-20 MPH.

TONIGHT: Variably cloudy. Breezy & muggy. Isolated showers possible. Lows in the 60s. Wind S to SW 10-20 MPH shifting to W late.

MONDAY: Mostly sunny. Less humid. Highs in the 70s. Wind W 10-20 MPH.

TUESDAY & WEDNESDAY: Fair weather. Lows in the 40s. Highs in the 60s.
