DAYS 1-5 (APRIL 29 – MAY 3)

On we go with the upper low spinning about just to our east, keeping us breezy and cool for the last couple days of April. These conditions mean that brush fire danger will be on the high side as well. High pressure nudges eastward to bring a fair and milder day to start off May and end the weekend. A weak low pressure area arrives from the west later Monday with some threat of wet weather, but this should move out on Tuesday with fair weather returning.

TODAY: Intervals of sun & clouds. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Sun/cloud mix. Highs 51-58. Wind NW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Lows 38-45. Wind W up to 10 MPH.

SUNDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 42-49. Wind variable under 10 MPH.

MONDAY: Increasing clouds. Afternoon rain showers possible. Highs 60-67. Wind S 5-15 MPH.

MONDAY NIGHT: Cloudy. Rain showers likely. Lows 48-55. Wind S up to 10 MPH.

TUESDAY: Clearing. Highs 60-67. Wind W up to 10 MPH.

DAYS 6-10 (MAY 4-8)

Unsettled weather with the passage of low pressure and a frontal system May 4, with another episode of unsettled weather later May 5 into May 6. Cooling trend expected.

DAYS 11-15 (MAY 9-13)

Similar pattern, weak blocking favoring cooler than normal temperatures and a tendency to be on the dry side.

C-19 Chat Post – 4-29-2022

DAYS 1-5 (APRIL 28 – MAY 2)

An upper level low pressure area – a pool of cold air – will sit just east of our region over the next 3 days. We’ll be on its western flank and vulnerable to cloudiness generated by it, along with breezy conditions and cool weather. Finally this system pulls to the east and we are calmer and milder by Sunday, the first day of May. Will that last through Monday? Probably not. Looks like another low pressure system will be waiting to move in by then as things start to move west to east again, but at this point it looks minor.

TODAY: Partly sunny. Highs 50-57. Wind N 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 37-44. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Sun/cloud mix. Highs 51-58. Wind NW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Lows 38-45. Wind W up to 10 MPH.

SUNDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 42-49. Wind variable under 10 MPH.

MONDAY: Increasing clouds. Afternoon rain showers possible. Highs 60-67. Wind S 5-15 MPH.

DAYS 6-10 (MAY 3-7)

High pressure dominates eastern Canada. Slowly eastward-moving weather systems dominate our pattern. Unsettled episodes most likely early May 4, later May 5 into May 6. Mildest early period, then a cooler trend again.

DAYS 11-15 (MAY 8-12)

Overall pattern looks similar with very little overall change to the set-up, resulting in kind of typical mid-spring weather with no extremes of temperature or major storminess, but a couple episodes of unsettled weather.

C-19 Chat Post – 4-28-2022

DAYS 1-5 (APRIL 27 – MAY 1)

Down to 4 days in April, and we’ll experience the effect of a blocking pattern for them. Low pressure exiting today sits east of New England through Saturday. We’ll be on the drier, cool side of it, but with it still close by today we have the chance of a shower, and a lobe or two of energy coming around its back side may introduce a brief shower threat to our region sometime in the coming 3 days, but I feel it’s a small enough threat to really just emphasize the periodic cloudiness we’ll be dealing with, as chances are most places don’t see any shower activity on those 3 days. Blocking opens up enough to nudge high pressure eastward into our area by Sunday, starting May off with a very nice day.

TODAY: Mostly cloudy to partly sunny. Brief passing rain showers possible. Highs 52-59. Wind N to NW 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 38-45. Wind NW 10-20 MPH.

THURSDAY: Partly sunny. Highs 50-57. Wind N 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 37-44. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Sun/cloud mix. Highs 51-58. Wind NW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Lows 38-45. Wind W up to 10 MPH.

SUNDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

DAYS 6-10 (MAY 2-6)

The pattern looks like it will present some blocking but also some movement. High pressure in eastern Canada and areas of low pressure moving eastward to the of that. Those disturbances will bring unsettled threats to us about every other day during this period, though timing will be difficult until it gets closer. Temperatures near to slightly below normal for the period as a whole.

DAYS 11-15 (MAY 7-11)

A similar pattern should continue to the one described just above and fine-tuning will take place as we get closer.

C-19 Chat Post – 4-27-2022

DAYS 1-5 (APRIL 26-30)

A milder day today but clouds dominant and eventually some wet weather likely later in the day into tonight as a low pressure system and cold front move in from west to east. This system will make it through by early Wednesday, and any wave of low pressure that I previously thought may keep us wet into Wednesday morning will be weaker and later-forming, so it looks mainly dry, breezy and cooler for Wednesday, other than just a chance of a brief shower from some instability in the atmosphere. While the progressive pattern is indeed slowing down and evolving into more of a blocking one, but we’ll find ourselves on the dry and cool side of it into late this week…

TODAY: Mostly cloudy. Scattered showers possible in southwestern NH and north central MA this morning, then anywhere during this afternoon. Highs 57-64. Wind S 10-20 MPH.

TONIGHT: Cloudy. Showers likely. Patchy fog. Lows 45-52. Wind variable 5-15 MPH.

WEDNESDAY: Partly sunny. A brief passing shower possible. Highs 52-59. Wind N to NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 10-20 MPH.

THURSDAY: Partly sunny. Highs 50-57. Wind N 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 37-44. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Sun/cloudy mix. Highs 51-58. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (MAY 1-5)

The blocking element of the pattern doesn’t look like it will be that strong, so leaning toward increasingly progressive movement of weather systems. This leads to a warming trend the first few days of May, eventually a shower threat, and return to cooler weather toward the end of the period, based on current timing expectations. This is not a high confidence forecast, however.

DAYS 11-15 (MAY 6-10)

Looking for a progressive but not fast-flowing upper level pattern. One or two unsettled weather systems will bring shower threats to the region. Temperatures, while variable, should average fairly close to normal.

C-19 Chat Post – 4-26-2022

DAYS 1-5 (APRIL 25-29)

Fairly typical spring weather will be ours as we head through the last week of April. The frontal boundary that came through as a back door cold front over the weekend sits near the western reaches of the WHW forecast area this morning, even triggering a few showers due to a disturbance moving by. These showers won’t last long and will impact eastern CT and parts of RI into mid morning. It’ll turn milder away from the coast than it was yesterday, but coastal areas will hang onto the cool air with onshore breezes off the still-chilly water. Tuesday, the aforementioned boundary returns as a warm front, but we only get into the warm sector behind this front and ahead of an approaching cold front for a brief period of time. That cold front, parented by low pressure passing to our north, will move through from west to east Tuesday night and offshore Wednesday just as a weak wave of low pressure forms on it and moves by, then helps pull it further offshore. While this will be taking place during the evolution of a blocking pattern, the low pressure area that brings the unsettled weather Tuesday to early Wednesday will end up far enough offshore that we are dry from later Wednesday through Friday. But the price to pay for the dry weather will be cool and breezy conditions with a north to northwest flow. It won’t be totally sunny any of these days either as we start with the clouds and some lingering wet weather Wednesday, then see diurnal cloud development underneath a pool of cold air aloft both Thursday and Friday.

TODAY: Clouds and showers eastern CT and parts of RI until about morning, otherwise sun/cloud mix. Highs 55-62 southern NH and eastern MA as well as South Coast, 63-70 interior MA, northern RI, and northeastern CT. Wind E up to 10 MPH shifting to S especially in areas west and south of Boston.

TONIGHT: Mostly cloudy. Lows 48-55. Wind S 5-15 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon. Highs 57-64. Wind S 10-20 MPH.

TUESDAY NIGHT: Cloudy. Showers likely. Patchy fog. Lows 45-52. Wind variable 5-15 MPH.

WEDNESDAY: Mostly cloudy with showers likely during the morning. Partly sunny with a chance of a shower in the afternoon. Highs 52-59. Wind N to NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 10-20 MPH.

THURSDAY: Partly sunny. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 37-44. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 50-57. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (APRIL 30 – MAY 4)

Blocking to slow progression in the pattern. Dry, cool to seasonable start as we transition from April to May. Unsettled weather around May 2-4 with a variable temperature trend, briefly milder then possibly much cooler.

DAYS 11-15 (MAY 5-9)

Still a a tendency for blocking to take place with slow-moving systems. At least one low pressure system should impact the region with unsettled weather, favoring the early part of the period. A lot of detail to work out, which can’t be done this far in advance.

C-19 Chat Post – 4-25-2022

DAYS 1-5 (APRIL 24-28)

We see the evolution of a blocking pattern take place during the next 5 days, typical of spring. We sit on the cool side of a frontal boundary that will make the WHW forecast area cooler than yesterday, and lots of clouds continue to stream down from the NW in the upper level air flow over us, but there is enough dry air that we see these clouds break for sun at times, so not a totally overcast day, and we’re also not seeing the low stratus clouds that can sometimes accompany these onshore air flows – lower levels are not saturated enough, so if you can put up with the cool air, especially near the coast, it’s not really going to be that bad a day today. The same will hold true Monday as the frontal boundary still sits to the south and west but then attempts to make its way back across the region later in the day and evening as a warm front, so areas especially south and west of Boston may see the benefit of a southerly air flow developing with a bit of warming. Tuesday, low pressure tracking north of our area will drag a cold front into the region with the increased opportunity for showers, and a wave of low pressure forming along that front as it goes by us may enhance and prolong shower activity from Tuesday night into part of Wednesday as the entire system slows down in response to developing atmospheric blocking. However, as I felt yesterday, I feel today that the orientation of the blocking set-up allows us to dry out more as we get to later Wednesday and Thursday, although it will be on the breezy and cool side.

TODAY: Lots of clouds, periodic sunshine. Highs 47-54 NH Seacoast, eastern MA, and immediate South Coast, 55-62 elsewhere. Wind NE to E 5-15 MPH.

TONIGHT: Mostly cloudy. Lows 40-47. Wind E 5-15 MPH.

MONDAY: Partly sunny. Highs 55-62 southern NH and eastern MA as well as South Coast, 63-70 interior MA, northern RI, and northeastern CT. Wind E up to 10 MPH shifting to S especially in areas west and south of Boston.

MONDAY NIGHT: Mostly cloudy. Lows 48-55. Wind S 5-15 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon. Highs 57-64. Wind S 10-20 MPH.

TUESDAY NIGHT: Cloudy. Showers likely. Patchy fog. Lows 45-52. Wind variable 5-15 MPH.

WEDNESDAY: Mostly cloudy with showers likely during the morning. Partly sunny with a chance of a shower in the afternoon. Highs 52-59. Wind N to NW 10-20 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 10-20 MPH.

THURSDAY: Partly sunny. Highs 50-57. Wind NW 10-20 MPH.

DAYS 6-10 (APRIL 29 – MAY 3)

Continued idea of blocking pattern with our area on the drier side of it initially, then finally some rain threat around May 1 or 2 as a system from the west makes its way in, but should exit for a drier end to the period. Temperatures should be variable, averaging near to below normal. This remains a lower than average confidence forecast for this time period.

DAYS 11-15 (MAY 4-8)

Still a a tendency for blocking to take place with slow-moving systems. Remains to be seen how much wet weather we end up with, but we may stay on the drier side of the block once again as well as with cooler air being dominant.

DAYS 1-5 (APRIL 23-27)

It’s weekend time! How’s the weather gonna be? Kind of typical springtime in New England, and in case you forgot that we here in the WHW forecast area live near a large body of water, the Atlantic Ocean, you’ll get a reminder. The set-up of weather systems we will see is fairly typical for this time of year. We have high pressure building in eastern Canada and a frontal boundary set to slip south southwestward across the region, but not before we have a decently mild day today (a touch cooler than yesterday). Sunday will end up noticeably cooler, most especially near the coastline. We’ll also see an abundance of high cloudiness sliding in from the northwest with the upper level winds today and these will thicken at times and thin at other times. Right now it looks like the thickest batch of cloud cover will move through tonight and in the pre-dawn hours of Sunday when some patches of light rain may fall. By the time we get to Monday, that boundary is going to try pushing back to the north and east as a warm front, and may succeed by later in the day, so I’m optimistic for breaking clouds, more sun, and warmer air, though it may be late-arriving the further east and north you are. When we get to Tuesday, we see a changing weather pattern start to take place with a low pressure area and frontal system arriving from the west during Tuesday then slowing down as it tries to exit Wednesday, when another wave of low pressure may become involved. This results in a period of unsettled weather, starting mild, then cooling down. There will be some details to fine-tune as we get closer.

TODAY: Sun/cloud mix, most abundant sun during the first half of the day. Highs 58-65. Wind NW to N up to 10 MPH but local coastal sea breezes.

TONIGHT: Mostly cloudy. Spotty light rain late evening-overnight. Lows 38-45. Wind N to NE up to 10 MPH may start to gust higher near the coast.

SUNDAY: Lots of clouds, periodic sunshine. Highs 47-54 NH Seacoast, eastern MA, and immediate South Coast, 55-62 elsewhere. Wind NE to E 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Lows 40-47. Wind E 5-15 MPH.

MONDAY: Partly sunny. Highs 55-62 southern NH and eastern MA as well as South Coast, 63-70 interior MA, northern RI, and northeastern CT. Wind variable 5-15 MPH, becoming S to SW.

MONDAY NIGHT: Mostly cloudy. Lows 48-55. Wind S 5-15 MPH.

TUESDAY: Mostly cloudy. Showers likely. Highs 57-64. Wind S 10-20 MPH.

TUESDAY NIGHT: Cloudy. Showers likely. Patchy fog. Lows 45-52. Wind variable 5-15 MPH.

WEDNESDAY: Mostly cloudy with showers likely during the morning. Partly sunny with a chance of a shower in the afternoon. Highs 52-59. Wind N to NW 10-20 MPH.

DAYS 6-10 (APRIL 28 – MAY 2)

We will see some atmospheric blocking and slower-moving weather systems. Right now it looks like the system from Tuesday/Wednesday will be far enough east to keep our area dry but breezy/cool as we head through the final few days of April before the next low pressure system threatens with more unsettled weather by the first couple days of May. This is not a high confidence forecast, however, in terms of the day-to-day weather.

DAYS 11-15 (MAY 3-7)

Blocking pattern potential with near to below normal temperatures, near to above normal precipitation at least early part of period. Block may break down mid to late period with zonal flow returning.
