Simple week as we end November and start December. High pressure slides in for a bright, chilly Monday even though a weak boundary will cross the region virtually unnoticed. Tuesday’s a cloudy day with a touch of light snow mainly near and south of the Mass Pike (mix Cape Cod & Islands). This will be a very low impact event as it is a flat open wave of low pressure moving very rapidly along to the east northeast with very little support. Upper level trough swings through Wednesday with lots of clouds and a few snow showers. High pressure will be in general control Thursday & Friday with chilly/dry weather, though a weak reinforcing cold front late Thursday will result in Friday being the colder of the 2 days. The weekend (December’s first two days) will likely present more clouds and moderating temperatures.

This evening’s update will focus on the week ahead (Monday through Sunday).

This update will focus on the last 6 days of November (today through Friday).

It’s a chilly/dry pattern for November’s home stretch. A strong west northwest flow that was established with a cold front’s passage early Saturday will continue today before relaxing Monday. It will be strong enough today to pick up moisture from the Great Lakes (snow showers abundant around that area to the mountains of western New England) and drag it across New England. A few stray snow showers may try to reach southern New England (especially the interior and hills) before drying up during this afternoon/evening. So this means that the sun from the morning will share the sky with clouds this afternoon. Monday will be a sunnier day as dry air is dominant and the air flow relaxes somewhat. An open wave of low pressure will move rapidly east northeastward from the Mid Atlantic into the waters southeast of New England Tuesday and Wednesday. This storm will intensify over water but be moving so quickly and be far enough south to limit the precipitation threat for southern New England. It will be cold enough for snow in most areas, except some mix/rain immediate coastal areas and over Cape Cod & the Islands. Anyway, precipitation will be very light from this event over most areas and any snow accumulation is likely to be limited. High pressure returns with cold/dry weather to end the week.

Forecast for eastern MA, RI, and southern NH…

TODAY: Mostly sunny this morning. Sun mixed with clouds this afternoon with a slight chance of a stray snow shower reaching some areas mainly well north and west of Boston. Highs around 40. Wind WNW 10-20 MPH gusting to 30 MPH.

TONIGHT: Partly cloudy with isolated light snow showers early, followed by clearing. Lows in the 20s. Wind W diminishing to around 10 MPH.

MONDAY: Mostly sunny. Highs around 40. Wind W 10-15 MPH.

TUESDAY: Cloudy. PM light snow inland, mix coast, mix/rain Cape Cod and the Islands. Low 22. High 38.

WEDNESDAY: Variably cloudy. Chance of snow showers. Low 27. High 38.

THURSDAY: Partly cloudy. Low 22. High 36.

FRIDAY: Mostly sunny. Low 21. High 40.

8:06AM

A cold front is now moving offshore and in will rush colder air for the balance of the weekend, along with gusty wind. High pressure will crest over southern New England Monday which will be a fair and chilly day. Low pressure will ride out of the Midwest and bring unsettled weather Tuesday and Wednesday with some rain and snow, but this will not be a significant system. The end of the week looks fair and chilly again as the overall pattern remains one featuring below normal temperatures and precipitation.

I hope anybody traveling today has made it safely to their destination! If you  have to travel on the holiday itself, no worries from the weather. Looks great as high pressure dominates. This high will hang around for “Black Friday” which will be a splendid day, with sunshine and mild air. It won’t last though. The chilly/dry pattern that we have been in will continue. We’ll snap right back to it with the passage of a strong cold front Saturday morning (a little earlier than I thought yesterday). This will bring a band of rain showers as the air will still be mild. But right behind it, in will flow the cold on a gusty wind later Saturday. This chilly air will stick around into early  next week. The next “event of note” will be the passage of a fairly weak storm system around the middle of next week. The timing is a little slower than on the previous forecast (Wednesday vs. Tuesday), and again it remains too early at 7 days distance to figure out the track and if any mix/snow will be involved, so a generic and low confidence forecast will be presented here regarding that event.

I would like to wish all of you a very Happy Thanksgiving! I hope you are all with people you love and can enjoy the day. Be safe this weekend! I will continue to update the blog throughout.

Forecast for eastern MA, RI, and southern NH…

TONIGHT: Areas of low clouds near the coast. A few high clouds otherwise. Patchy fog forming in valleys, swamps, and bogs. Areas of frost. Lows upper 20s to middle 30s, lowest in the valley areas. Wind NE under 10 MPH becoming calm.

THURSDAY NIGHT: Clear. Lows 33-38. Wind S under 10 MPH.

FRIDAY: Sunny until late in the day when the sun will set into a deck of clouds in the west. Highs 53-58. Wind S to SW around 10 MPH.

FRIDAY NIGHT: Clouds move in west to east along with a threat of rain showers toward dawn. Lows 43-48. Wind SW 5-15 MPH.

SATURDAY: Mostly cloudy with passing rain showers in the morning, then partly cloudy. Highs around 50 then falling through the 40s during the day and into the 30s by evening. Wind SW 5-15 MPH shifting to NW and increasing to 15-25 MPH.

7:32PM

The quiet pattern continues and will last through Friday before some changes take place. High pressure northeast of New England and low pressure far to the southeast will combine to cause a weak to moderate east to northeast flow over southern New England through Wednesday as a weak upper trough moves in from the west. This will promote a variably cloudy sky through Wednesday night along with cool air, but with no precipitation, conditions will be excellent for traveling just before Thanksgiving Day. The holiday itself on Thursday will be a very nice one as a narrow high pressure area builds overhead, and this high will push offshore on Black Friday, resulting in a fair and milder day, conducive to heavy mall traffic and lots of money spending.

The remainder of Thanksgiving weekend will see some changes take place. A strong cold front will approach then cross the region Saturday and Saturday night. A band of rain showers will accompany the front as the air will still be mild ahead of it. But a sharp shot of cold air will come in as the front passes (exact timing remains to be seen but best guess is Saturday evening for the front to cross the region). Most of the moisture will be offshore rather quickly so the chance of snow showers on Sunday is remote, at best. But if any moisture is around it would be cold enough to support snow showers.

Looking into early next week, a fair and cold Monday should be followed by a threat of unsettled weather Tuesday (too early to be sure on rain vs. snow, or the significance of the event).

Are you looking for good news about traveling around the area this week, and decent weather for Thanksgiving football games? What about Black Friday shopping? And what’s next weekend going to be like? I think you’ll like the answers for the most part.

High pressure will dominate the region Monday into Tuesday with fair weather. As the center of this high shifts northeastward into the Canadian Maritimes later Tuesday and Wednesday, and low pressure forms well southeast of New England, an onshore flow will promote some low clouds from the ocean at least in southeastern and eastern sections. Also, a trough in upper levels approaching from the southwest will also add some cloudiness to the region by midweek. Based on current expected timing, rebuilding high pressure should push the clouds offshore on Thanksgiving, which should be a fair and seasonable day. This high will sit overhead and milder air will make for a perfect Black  Friday. Looking ahead to next weekend, a cold front and low pressure trough should bring slightly unsettled and eventually colder weather to the region.

Forecast for eastern MA, RI, and southern NH…

OVERNIGHT: Partly cloudy. Lows 22-27 except 28-33 coast and urban centers. Wind N under 10 MPH.

No major changes to the discussion. Summarizing, high pressure centered north of New England will provide quiet and chilly weather this weekend. Only some low clouds will come off the ocean at times in southeastern MA, Cape Cod, and the Islands, due to a north northeast wind flow of chilly air over relatively warm water. Early next week, storminess will develop in the western Atlantic but stay far enough offshore to not have a direct impact. What may happen is that the flow between it and high pressure to the north may send low clouds in from the ocean by Tuesday/Wednesday, and even without that some of the higher and middle clouds around the storm’s circulation would possibly expand over the region. As for travel weather heading into the Thanksgiving holiday, expect mainly favorable conditions.

Updated forecast for eastern MA, RI, and southern NH…

OVERNIGHT: Clearing. Lows middle 20s inland valleys to middle 30s urban centers. Wind N under 10 MPH.

SATURDAY: Low clouds at times from Plymouth County MA southward. Sunny elsewhere. Highs around 50. Wind N-NNE 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows upper 20s inland valleys to middle 30s coast. Wind light N-NNE.

SUNDAY: Mostly sunny to partly cloudy with some additional low clouds in far southeastern MA. Highs around 50. Wind NNE 5-15 MPH.

MONDAY: Partly cloudy. Low 31. High 51.

TUESDAY: Mostly cloudy. Low 33. High 48.

WEDNESDAY: Mostly cloudy. Low 37. High 47.

THURSDAY – THANKSGIVING: Partly cloudy. Low 33. High 52.

10:02PM

High pressure to the north and evolving low pressure far to the south and east will keep southern New England on the chilly, dry side for the next several days. A north northeast wind at low levels will drive some additional low cloudiness across southeastern MA Friday. A weak disturbance at high levels will spread some high cloudiness across the sky Friday as well. Sunshine will dominate the weekend. A broad low pressure area will organize to the southeast of New England during the first part of next week, but far enough out there so that we never see any precipitation from it, only some cloudiness. This is good news regarding the weather for pre-Thanksgiving travel.

Forecast for eastern MA, RI, and southern NH…

OVERNIGHT & FRIDAY: Variable high cloudiness but still some sunshine during the day except in southeastern MA, Cape Cold, & the Islands where areas of low clouds continue. Highs 45-50. Wind N 5-15 MPH.

SUNDAY: Mostly sunny. Highs 45-50. Wind variable 5-15 MPH.

MONDAY: Partly sunny. Low 29. High 48.

TUESDAY: Mostly cloudy. Low 33. High 50.

THURSDAY – THANKSGIVING DAY:  Partly cloudy. Low 32. High 54.

My outlook for this winter is pretty straightforward, and will presented just that way. I’m going to spare going into detail on the technical stuff and we can discuss that in the comment section below if you are interested.

What I will say is that all major factors influencing climate were taken into account (PDO, AO, NAO, QBO, solar cycle, ENSO, among other things). The major players in the pattern this winter will be an easterly QBO (winds predominantly from the east at high altitudes over the equatorial Pacific Ocean), neutral ENSO (neither La Nina nor El Nino), an often negative AO/NAO (blocking pattern in the northern hemisphere), and a weak solar maximum (higher sunspot activity but not out of control).

I think the most important thing these lead to is a tendency for drier than normal conditions (which may become a problem as 2013 goes on). This is a pattern of variable temperatures but frequent spells of cooler than normal weather, which we have not seen for the better part of a couple years. The general pattern under this setup features a mean ridge position in the middle of the US with troughs dominating both the East and West Coasts. This pattern also favors frequent cut-off low pressure areas near or off the East Coast. The blocking may be fairly strong on a frequent basis, and this is the reasoning for the drier forecast. Blocking too strong would force many  of the storms to be too far south and/or east to have major impact on New England. This type of a pattern may spell out bigger snow totals for the Middle Atlantic.

So, what are we gonna see? I will consider the 2012-2013 winter to be December 1 through March 31, even though we can and do see snow in April and even as late as May. The winter overall should feature near to below normal temperatures, below normal precipitation, and near to below normal snowfall. The month by month breakdown:

December… Temperature: near to below normal. Precipitation: below normal. Snow: near to below normal.

January… Temperature: below to much below normal. Precipitation: below normal. Snow: near to below normal.

Feburary… Temperature: near to below normal. Precipitation: near to below normal.  Snow: near to below normal.

March… Temperature: near normal. Precipitation: near to above normal. Snow: Near to above normal.

No big changes from the previous discussion. Dry, chilly pattern continues through the weekend. Watching an ocean storm for early next week, battling with high pressure to the north. The indications are for the storm to evolve a little further to the south and east, lessening the chance of direct impact from stronger winds and heavier precipitation, but probably close enough to at least through clouds over the region. Again, still far away, with time to fine-tune. With a big travel week next week, this forecast is very important.

In the short term, there will still be some issues with minor coastal flooding through Thursday at high tide times.

Updated forecast for eastern MA, RI, and southern NH…

OVERNIGHT: Cloudy intervals southeastern MA. Clear elsewhere. Lows 25-30 inland valleys, 30-38 elsewhere, mildest near the coast and in urban centers. Wind N 5-15 MPH.

THURSDAY: Occasional low clouds from the ocean over southeastern Massachusetts, the Cape and Islands. Mostly sunny elsewhere (some high clouds from the southwest later). Highs 42-47. Wind N-NE 10-20 MPH.

THURSDAY NIGHT: Occasional low clouds from the ocean over southeastern MA, Cape Cod, and the Islands. Variable high clouds elsewhere. Lows 25-30 inland, 31-36 coast. Wind N-NE 5-15 MPH.

The warmth is gone, as is the rain, the really picturesque sky at sunset Tuesday, and the super bright rainbows that some got to enjoy. That was all part of the transition between a very mild air mass and a return to a chilly stretch of weather, which is getting underway now and will last for several days. With high pressure centered mostly to the north of New England, a north to northeasterly flow will be dominant, keeping the weather mainly dry. Clouds from the departing cold front will linger over Cape Cod and the Islands today.  Also, an astronomically high tide combined with a north to northeast wind may allow for some minor coastal flooding in prone areas especially midday Wednesday and Thursday. Some low clouds from the ocean may occur over southeastern Massachusetts Thursday. Some high clouds may cross the southern New England sky from late Thursday into part of Friday as a weak disturbance at high levels of the atmosphere propagates through. Otherwise, sunshine will dominate most days through Saturday. Beyond this, the questions start. We do know there will be another storm developing south of New England, which will try to push northward, while high pressure holds strong to the north. This may eventually lead to increasing northeast to east winds, a sky turning cloudy, and a rain threat. The timing  suggest we make it through Sunday dry followed by a rain threat early next week. This is still far off with much uncertainty.

Forecast for eastern MA, RI, and southern NH…

TODAY: Lots of clouds from Plymouth County MA through Cape Cod & the Islands. Sunshine elsewhere. Highs 43-48. Wind N-NE 10-15 MPH.

TONIGHT: Clouds depart Cape Cod & the Islands. Clear elsewhere. Lows 25-30 inland valleys, 30-38 elsewhere, mildest near the coast and in urban centers. Wind N 5-15 MPH.

THURSDAY: Occasional low clouds from the ocean over far southeastern Massachusetts, the Cape and Islands. Mostly sunny elsewhere (some high clouds from the southwest later). Highs 42-47. Wind N-NE 10-20 MPH.

THURSDAY NIGHT: Occasional low clouds from the ocean over southeastern MA, Cape Cod, and the Islands. Variable high clouds elsewhere. Lows 25-30 inland, 31-36 coast. Wind N-NE 5-15 MPH.

FRIDAY: Partly cloudy to mostly sunny. Highs 44-49. Wind NE-N 10-15 MPH.

SATURDAY: Sunny. Low 24. High 47.

MONDAY: Cloudy. Chance of rain south. Low 35. High 45.

TUESDAY: Cloudy. Chance of rain south. Low 35. High 45.

7:27AM

A cold front will slice through the region today with showers, even a few thunderstorms, and cooling air. This will set the stage for a chilly and dry remainder of the week. Sunshine will dominate Wednesday, sun & clouds will share parts of Thursday & Friday as a weak disturbance drifts through the region, and sunshine is expected to again dominate at least the start of the weekend. More cloudiness may arrive later in the weekend as we watch an area of low pressure to the south and high pressure to the north setting up a battle zone.

Updated forecast for eastern MA, RI, and southern NH…

TODAY: Cloudy. Periods of showers and possibly a thunderstorm, with a few downpours. Temperatures cooling through the 50s and into the 40s. Wind SW 10-20 MPH with higher gusts, shifting to NW.

TONIGHT: Slow clearing west to east. Lows 32-37. Wind N 5-15 MPH.

WEDNESDAY: Sunny. Highs 42-47. Wind N 5-15 MPH.

FRIDAY: Partly to mostly sunny. Low 28. High 46.

SATURDAY: Mostly sunny. Low 27. High 50.

SUNDAY: Partly sunny. Low 33. High 49.

10:52PM

Heading into the new week, it looks much the same as described on the previous post. Indian Summer weather will be the theme of Monday (which is a holiday for some people). Tuesday will be a day of transition as a cold front slides west to east through the region. Showery weather should be occurring mainly during the first half of the day with the front. This front may be a bit slow to clear the coast with clouds lingering there early Wednesday, otherwise the middle and end of the week will feature dry weather with a seasonable chill as high pressure is in general control.

Forecast for eastern MA, RI, and southern NH…

MONDAY: Areas of low clouds and patchy fog into mid morning, a sunny interval late morning into mid afternoon, then clouds increasing by late day. Highs 65-70 except 60-65 South Coast. Wind SW 5-15 MPH with higher gusts.

MONDAY NIGHT: Cloudy. Rain showers after midnight. Lows 50-55. Wind S 5-15 MPH.

TUESDAY: Cloudy. Showers in the morning. Highs 55-60 early then cooling toward 50. Wind S 5-15 MPH in the morning shifting to NW from midday on.

WEDNESDAY: Early clouds Cape Cod & Islands otherwise sunny. Low 33. High 48.

THURSDAY: Mostly sunny to partly cloudy. Low 29. High 46.

FRIDAY: Partly cloudy to mostly sunny. Low 29. High 45.

SATURDAY: Mostly sunny. Low 28. High 47.

SUNDAY: Mostly sunny. Low 29. High 49.

11:24AM

The next 7 days will feature 3 days of warming, a day of transition, and 3 days of chill. Today through Monday (long Veterans Day weekend for some) will feature fair weather and a warming trend, with sun much of today, clouds tonight as a warm front pushes through, a return to some sun Sunday, and even more sun with Indian Summer warmth for Monday. Tuesday will be the divide as a front moves across the region bringing a cloudy sky and a period of rain or showers at some point (working on the exact timing). Wednesday through Friday will be governed by high pressure and will be bright days with a typical November chill.
