SYNOPSIS
A warming trend arrives today into Saturday as high pressure builds south of New England, but becoming blustery on Saturday as a front crosses the region. A strong fall frontal system then affects Southern New England for Sunday and into Monday, which will bring a couple periods of steadier rains and cooler than normal temperatures. Drying out by Tuesday. Fall-like blustery conditions and below normal temperatures are favored for Tuesday and Wednesday, and highs could be some 10 degrees colder than normal. Temperatures slowly warm towards normal by the end of the work week.
NEAR TERM /UNTIL 6 PM THIS EVENING/
Shortwave ridging moves into New Eng today as high pres builds over the mid Atlc region. Not much moisture in the low levels and temps aloft are warming so expect abundant sunshine with limited to no CU development. 925 mb warming to 10-11C this afternoon, so after a chilly start temps will recover nicely with afternoon highs reaching mid-upper 60s, cooler higher terrain. It will still be a bit breezy with a well mixed boundary layer supporting NW winds 10-20 mph, but diminishing and shifting to W by later today.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
Tonight...
Fairly robust mid level shortwave north of the Gt Lakes will drop SE but track well to the north toward 12z Sat. Cold front assocd with this shortwave moves southward across northern New Eng overnight.
Limited moisture with this front so not expecting any precip, with just some mid-high clouds moving through. Decent low level jet ahead of the front develops tonight. Low level inversion will prevent the stronger winds from mixing down, but we do expect modest SW winds which will become gusty overnight over the Cape/Islands where shallow mixing supports 20-30 mph gusts. The winds will result in a milder night with lows upper 40s to mid 50s.
Saturday...
The mid level shortwave moves eastward from Maine and pushes the cold front south across the region in the morning. This will be a dry frontal passage and will be followed by very dry airmass as PWATs drop to around 0.25". Full sunshine expected but it will be windy into early afternoon with soundings suggesting NW gusts up to 25-35 mph before slackening mid to late afternoon. Cooler air behind the front will lag to the north allowing for a mild day. Highs will reach mid-upper 60s, but some lower 70s possible across CT/RI and SE MA where low level temps are warmest.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Key Points:
* A frontal system brings the next chance at rainfall bringing periods of rain Sunday into Monday.
* Cooler airmass settles over the region through Thursday bringing below normal temperatures across southern New England.
Details:
Saturday Night through Monday:
Limited cloud cover earlier Saturday night should lead to optimal cooling. Temperatures likely drop into the mid/upper 30s for the interior and 40s closer to the coast. Clouds increase from west to east early Sunday morning ahead of the next system.
There is a good consensus among model guidance that a deep trough moves across the Great Lakes region pushing eastward across the northeast U.S. Sunday into Monday. This will bring our next chance at rainfall for southern New England. Portions of the details stay blurry with more uncertainty being expressed in the track of the low and front placement. The track itself will have influence on rain totals and rain probabilities. What we do know is that in the Sunday through Monday timeframe, there are increasing chances for areas to receive periods of rain. How the system tracks could have some influence on timing as well. A round of rain is possible as early as early Sunday morning with additional rounds moving through Sunday afternoon, overnight, and into Monday.
Plenty of moisture available ahead of this upper trough/system with precipitable water values 120-160% of normal. This will more likely support periods of moderate rain with widespread heavy rainfall unlikely. In terms of QPF, ensemble 50th percentile shows a range from 0.20-0.65" by Mon PM. The lower end of the range was highlighted by the GEFS which had a more north track. The 00z ECMWF ens trended a bit wetter than previous runs, displaying 1-1.2" for a high end (low prob)
event. Otherwise other runs stay 1" or less. Temperatures Sunday will also be uncertain as well with dependence on the position of the warm front. Given the unsettled pattern, it is more likely to see highs in the 50s with some low-mid 60s toward the south coast and on the Cape. Conditions gradually dry out Monday afternoon into Monday evening.
Tuesday through Thursday:
A deep trough sliding across the northeast will keep anomalously cooler air over the region Tuesday and Wednesday. During this time frame, expect temperatures below normal in the 50s with chillier nights dropping into the 30s. There isn't a strong signal for precipitation during this period, but can't rule out a few showers each day. Breezy W/NW winds will also accompany this cool late fall- like airmass.
