Cold Then A Thaw

8:20AM

A cold front passed by overnight, quietly in southern New England, but not before putting down several inches of snow in some of the northern New England ski areas! It’s also been cold enough up there to be making snow, so a bit of an early start to the season for some.

The cold front will come to a halt just south of New England today and mild air to the southwest and west of the region will ride up over it, creating lots of clouds today and Saturday. Some light precipitation may break out on Saturday but not looking for a heavy event. By Sunday, the front will have returned northward as a warm front and will introduce a thaw that will last a few days, until a cold front brings us back to the chill around the middle of next week.

November To End Cold & Dry

8:42AM

It sounds like a rerun but the overall chilly/dry pattern of November will maintain itself right through the last few days of the month and into the first hours of December before moderation takes place for the early days of the new month.

The mostly non-storm (except some bands of moderate snow and accumulation in parts of far southern New England) is in a doddle just offshore but will pull away later today, allowing high pressure to build in for Thursday. A cold front will cross the region from northwest to southeast Thursday night, reinforcing the cold air for Friday.

As December starts, Saturday & Sunday will feature the approach and passage of a warm front which will bring clouds and eventually moderating temperatures. But with lots of dry air around and not a tremendous moisture punch with the front, precipitation will be scarce at best, and for now is being excluded from the forecast which follows this discussion.

Looking ahead into early next week, following the guidance of the European computer model which shows a bit more up and down temperature swings versus a mild spell. It still looks like a dry pattern even with the swings.

The Week Ahead

2:44AM

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.

Forecast for eastern MA, RI, and southern NH…

TODAY: Mostly sunny. Highs 40-45. Wind W 10-15 MPH with gusts 20-25 MPH.

TONIGHT: Increasing clouds south to north. Lows 23-28. Wind light variable.

TUESDAY: Cloudy. A period of light snow mainly across the southern half of eastern MA and RI except mixed rain/snow in coastal RI across Cape Cod & the Islands. Snow accumulation less than 1 inch in areas that it falls. Highs 35-40. Wind NE 5-10 MPH.

TUESDAY NIGHT: Decreasing clouds northwest to southeast. Lows 22-27. Wind N 5-15 MPH.

WEDNESDAY: Variably cloudy.  Chance of snow showers. Highs 35-40. Wind NW 10-20 MPH.

November’s Home Stretch

9:15AM

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.

Turning Colder

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.

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

TODAY: Variably cloudy. Highs around 45 through midday then falling to the 30s late. Wind W 10-20 MPH gusting around 30 MPH.

TONIGHT: Partly cloudy. Lows around 30. Wind W 10-20 MPH gusting to 30 MPH.

SUNDAY: Mostly sunny. Highs around 40. Wind W 10-20 MPH gusting to 30 MPH.

TUESDAY: Increasing clouds. Rain late. Low 28. High 46.

WEDNESDAY: Mostly cloudy. AM mix / PM snow showers. Low 30. High 40.

Thanksgiving Weekend Forecast

5:45PM

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.

Thanksgiving Week Update (Tuesday)

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).

The Week Ahead

9:17PM

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.
