Unstormy

9:45PM

** SHORT TERM UPDATE **

A low pressure wave in the Gulf of Maine has shoved the warm front back to the south as a back-door cold front that has now chilled down southern NH and most of eastern MA. Temperatures have fallen from the lower 40s to the lower 30s and with some fog forming, there may be some patchy ice forming on untreated surfaces overnight. Be aware of this if you are heading outside tomorrow morning as it probably will remain chilly into mid morning.

A slight tweak to the forecast appears in the TONIGHT section below, otherwise, the remainder is unchanged from the original post.

4:34PM

The lack of significant winter storms will continue, in fact there is very little risk of important storminess for the foreseeable future (that is, 7 days, possibly longer). Temperatures will continue to ride a little bit of a roller coaster, though this will not be extreme either. Brief cold shots come between near to above normal temperature stretches, with the midwinter chill being a bit more dominant in the days ahead.

A warm front passed by early Tuesday. Snowfall was less than expected, with most occurring across NH and Maine. A cold front will pass by on Wednesday, but with very  mild air in place expect a risk of rain showers in a short window of time just ahead of the front. Generally dry weather is expected Thursday through the weekend as a sprawling area of high pressure builds across eastern Canada and the northeastern US. Low pressure will pass well south of the region Thursday with no impact.

Boston Area Forecast…

TONIGHT: Variably cloudy. Areas of fog with moisture freezing on some untreated surfaces. Low 30-35. Wind light NE.

Temperatures Up & Down, No Major Storms

3:06AM

A warm front will cross eastern MA today with some snow (little accumulation) to mix. Low pressure passing to our north will push its cold front through during Wednesday, accompanied by rain showers due to a very mild air mass which will be over the region. High pressure will slowly build in and dominate the weather Thursday through Sunday. Low pressure will pass just south of New England Thursday and will try to skirt the South Coast with some light precipitation but it is not expected to be far enough north to bring anything into the Boston area. The next storm threat would be Monday of next week but it is far too early to tell any detail about that potential system. The overall weather pattern remains quiet.

Boston Area Forecast…

TONIGHT: Mostly cloudy. Low 35-40. Wind SW up to 10 MPH.

WEDNESDAY: Variably cloudy. Chance of rain showers through mid afternoon. High 52-57. Wind SW increasing to 10-20 MPH shifting to W late.

WEDNESDAY NIGHT: Partly cloudy. Low 30-35. Wind W 10-15 MPH.

On to the weather…

A weak cold front passed by last night with clouds and some gusty winds. We will be in between that and a slightly stronger cold front approaching from the west today, so expect a fair but breezy and chilly (but not too cold) day for late January. The second cold front will cross the region from west to east tonight after midnight, and is expected to produce snow showers and possibly a few snow squalls with minor snow accumulation in spots. Monday will be a breezy and cold day, but again not very cold by late January standards. A warm front will move  across the region Tuesday, and ahead of it an area of light snow will develop and move across New England as warm air rides up over the cold air in place. Again a minor snow accumulation is expected, but this may be a more general or widespread snowfall, and may come just in time to slick up some roads for Tuesday morning’s commute, so be aware in case… The warmer air behind the cold front will move in Tuesday night into Wednesday, with yet another wintertime 50-degree day not out of the question Wednesday. A cold front will approach from the west later Wednesday, but with the warm air in place expect rain showers.

I know there have been some storm threats advertised in media’s  longer range forecasts for the end of the week and next weekend, but at this point I am going to cautiously stay away from this scenario and say that the lack of phasing of jet streams to the south and north of New England will leave us in the middle with weak high pressure in general control and a few moisture-starved weak frontal systems passing by from Thursday through next weekend. The end of the week is not being forecast with high confidence so please check back for updates as the week goes on.

In the mean time, this is my take on things for the Boston Area…

TODAY: Mostly sunny. High 41-46. Wind W 10-20 MPH gusting 25-30 MPH at times.

TONIGHT: Partly to mostly cloudy. Scattered snow showers especially 11PM to 3AM from west to east, with a heavier snow squall possible. Snow accumulation of 1/2 inch or less. Low 23-28. Wind SW 10-20 MPH with higher gusts shifting back to W.

MONDAY: Mostly sunny. High 32-37. Wind W 10-20 MPH gusting 25-30 MPH at times.

MONDAY NIGHT: Increasing clouds. Light snow west to east before dawn. Low 20-25. Wind light variable.

TUESDAY: Cloudy with light snow ending west to east in the morning after accumulating 1 inch or less in most areas. Mostly cloudy to partly sunny late morning through afternoon. High 40-45. Wind variable becoming S up to 10 MPH.

WEDNESDAY: Mostly cloudy. Chance of rain showers. Low 39. High 51.

THURSDAY: Partly sunny. Low 30. High 41.

FRIDAY: Mostly sunny. Low 22. High 38.

SATURDAY: Partly cloudy. Low 22. High 40.

No Big Changes

3:00AM

We’ll continue with the pattern described in the previous blog for several days. I suspect the only changes will be to tweak timing and details of passing weather systems. We’ll see mostly minor to moderate precipitation events, with the odds favoring rain versus snow for the majority of what falls. The most unsettled times appear to be slated for Thursday night and the first half of Friday, late Sunday, and Wednesday of next week.

Boston Area Forecast…

OVERNIGHT: Mostly cloudy. A period of light snow, especially north of  Boston, dusting the ground. Low 25-30. Wind NW under 10 MPH.

THURSDAY: Mostly cloudy. High 35-40. Wind N up to 10 MPH.

THURSDAY NIGHT: Cloudy. Snow developing north and west of Boston, mixed rain and snow near and south of Boston, with a slushy coating to 1 inch of snow possible especially in the region outside of Route 95 to around route 495, north of the Mass Pike, before midnight. Mix to mainly rain after midnight. Low 30-35 early then temperature rising toward 40.  Wind E up to 10 MPH.

FRIDAY: Cloudy with rain in the morning. Mostly cloudy with a chance of rain showers in the afternoon. High 45-50. Wind S 5-15 MPH shifting to W.

SATURDAY: Partly cloudy. Low 30. High 43.

WEDNESDAY: Mostly cloudy. Chance of rain showers. Low 32. High 47.

Cool To Mild, Weak Storms

2:49AM

High pressure brings cool but dry weather today into Thursday. A weak storm moving southwest to northeast will bring a light mix to rain event late Thursday night into Friday. The next threat of precipitation will come over the weekend and it may be cold enough for now, but that looks like an insignificant event at this time.

Boston Area Forecast…

TODAY: Partly cloudy. High 38-43. Wind NW 10-20 MPH.

No Major Cold, No Major Snow Remainder Of January

4:40PM

After a slight bit more persistence to the wintry feel last week, we have returned to the pattern of milder than normal, brief cold shots, and no major snow threats that I am pretty confident will last through the remaining 8 days of January.

A frontal system will push west to east across New England tonight and early Tuesday morning as its parent low pressure area moves across southern Canada. High pressure builds into the region for midweek with dry and chilly weather, but no major cold. Several disorganized low pressure areas will be around at the end of the week, and at this point I’m still not sure how things happen down to the letter, but it looks like we’ll be affected by one weak low bringing enough mild air for a light snow to rain event late Thursday night and Friday, a weak storm offshore but possibly close enough for light snow/mix on Saturday, and upper level low pressure from the west bringing a snow shower threat for Sunday. Check back for more detail on the end of the week and for now just take my low confidence forecast with a grain of salt.

Boston Area Forecast…

TONIGHT: Cloudy. Areas of fog. Periods of rain showers. Temperature rising through the 40s. Wind SE under 10 MPH shifting to SW up to 15 MPH.

WEDNESDAY: Mostly sunny. High 37-42. Wind NW 10-20 MPH.

THURSDAY: Sunshine, late clouds, light snow/mix late night. Low 22. High 37.

FRIDAY: Cloudy. Light rain early. Low 35. High 45.

SATURDAY: Mostly cloudy. Chance of light snow/mix. Low 30. High 40.

SUNDAY: Variably cloudy. Chance of snow showers. Low 25. High 35.

The Week Ahead

9:38PM

HIGHLIGHTS…

Icy start inland Monday.

50 degrees early Tuesday?

Chilly midweek.

Unsettled late week.

DISCUSSION…

Low pressure will track northeastward across the Great Lakes and into eastern Canada through Tuesday. A warm front will move into southern New England Monday, but cold air trapped at the surface, especially away from the coast, means that some icing is possible Monday morning. The good news is that most of the precipitation should be in the form of freezing drizzle and not heavier freezing rain during the morning hours. However, some icy untreated roads, walks, stairs, and driveways are likely before temperatures finally warm to above freezing in most areas by afternoon. At that time, steadier rain should move in as a cold front approaches from the west. This front will cross the region at night and temperatures will warm steadily ahead of it, possibly reaching 50 Monday night or very early Tuesday. During the day Tuesday expect a drier southwest to west air flow and sun mixed with clouds, as the main front will be moving offshore. A secondary front later Tuesday may produce a rain or snow shower, but its main purpose will be to introduce dry and chilly weather for midweek.

The next series of storm systems will threaten the region from Thursday night into next weekend, bringing unsettled weather. It is too early to know details of these systems, but there is some threat of snow.
