SYNOPSIS
Dry, blustery and cold weather continues across the region today.
While it will remain rather cold tonight and Thursday the winds will diminish as high pressure builds to our south. This high pressure system shifts off the coast and results in moderating temps Friday and especially by Saturday. A cold front will bring a period of rain showers to the region Saturday afternoon and evening. Another wave of low pressure may bring a period of snow or rain changing to snow late Sunday into Monday morning. A shot of bitterly cold air follows Monday night into Tuesday with wind chills dropping below zero.
NEAR TERM /UNTIL 6 PM THIS EVENING/
* Cool and blustery today
Mainly quiet weather being observed early this morning across southern New England. Winds are marginally breezy or elevated with gusts up to 25 mph. An area of ocean-effect showers have been over the outer Cape for a couple of hours early this morning. This brought a short period of light snow overnight.
Recent radar trends have shown these showers dissipating.
Another cool and breezy day on tap with high pressure building southwest of the region and low pressure to the east. The increased pressure gradient and CAA regime will support breezy conditions again today with gusts 20-30 mph. Moisture will be in low amounts; however, NW flow will help support ocean-effect bands offshore of the Cape. High temperatures will be similar to Tuesday in the upper 20s and low 30s.
SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/
Key Messages:
* Diminishing winds tonight with chilly temperatures.
* Chances for scattered light snow showers by Thursday PM, mainly for south coast.
Tonight:
Winds gradually diminish tonight as the pressure gradient weakens. Mainly clear skies and weaker winds will support ample radiational cooling overnight with lows in the teens. A few of the higher spots in western MA may drop into the single digits.
Thursday:
A mid-level shortwave trough approaches the region Thursday.
This will shift winds to light SW. Conditions remain dry during the day with increasing cloud cover as moisture advects in.
High temperatures range in the upper 20s to low 30s. By early evening, there will be chances for scattered light snow showers, mainly across the south coast.
LONG TERM /FRIDAY THROUGH TUESDAY/
Key Messages...
* Dry Fri with seasonable high temps in the middle to upper 30s * Milder Sat with highs in the 40s & some afternoon/evening showers * Period of snow or rain changing to snow likely Sun PM-Mon AM * Arctic air with below zero wind chills Mon night into Tue
Details...
Thursday night and Friday...
A mid level shortwave will cross the region Thu night. It will mainly be associated with just a period of clouds...but a few brief snow showers are possible especially near the south coast with cold WSW flow and 850T at or below -10C. Either way should not be a big deal. Low temps Thu night should be mainly in the teens to the lower 20s.
A ridge of high pressure builds back into the region on Fri. This will bring plenty of sunshine with seasonable high temps in the middle to upper 30s
Winds will be rather light
so it will be a pleasant day for January standards.
Saturday...
This will be the mildest day of the week. A ridge of high pressure to our south will have moved off this coast. This allows a return southwest flow of milder air to work into southern New England. 925T moderate to near 0c and with gusty SW winds should push highs well into the 40s and it is not out of the question that a few spots hit 50 degrees.
A shortwave trough will approach the region Sat afternoon and evening. This should increase the forcing for ascent and result in a period of showers Sat afternoon into the evening. Not expecting a lot of rainfall by any means though and the showers should be short- lived.
Sunday into Monday...
Although the cold front will have already crossed the region by Sun it will take sometime for the colder air to work into the area.
Therefore...thinking we will see highs in the upper 30s to the middle 40s on Sun.
The biggest uncertainty revolves around the potential for a period of snow or rain changing to snow late Sun into Mon AM. What exactly unfolds will depend upon the track of an anafrontal wave. There is still considerable spread among the EPS/GEFS/CMC individual ensemble members. Depending on how close this wave tracks to the coast will determine whether or not we are dealing with a period of accumulating snow or rain changing to snow. We still need another day or two until we have better confidence on the potential outcomes. This is certainly something we will need to keep a close eye on in the coming days.
Monday night and Tuesday...
A shot of arctic air will be ushered into the region Mon night into Tue with 850T dropping into the -23c/-24C range. Low temps Mon night will probably be in the single digits across much of of the region.
Highs on Tue may not break 20 across a good portion of the region.
Wind chills will dip below zero Mon night into Tue morning with this shot of arctic air.
