SYNOPSIS

High pressure over southern New England will bring dry weather through mid week. It will be cooler Wednesday along the coast with sea breezes. Isolated to scattered showers across the interior Thursday with slightly below normal temperatures. Dry on Friday with high pressure in control. A cold front brings another round of light rain showers late Friday through Saturday. Turning drier Sunday and Monday.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/

Full sunny skies out there for many in southern New England with the exception of some widely scattered diurnal cumulus clouds (though far fewer than yesterday). This combined with temperatures currently in the mid to upper 60s are making for a fantastic Spring day across the region under dry northwest flow. The quiet weather continues tonight beneath a building mid level ridge and surface high pressure. This leads to clear skies and light winds (decoupling boundary layer) tonight allowing for efficient radiational cooling.
This means lows dipping into the upper 30s in our typical cold spots, closer to the mid 50s along the coast and in urban centers.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/

The mid level ridge axis shifts directly overhead on Wednesday leading to sunny skies for a good portion of the day and dry weather all day. The skies will fill in with high clouds from west to east starting mid morning, thickening and lowering through the day ahead of a warm front. Temperatures during the day will be quite different along the coast compared to inland locations thanks to a seabreeze.
By afternoon we expect temps in the low to mid 50s along the coast and low to mid 60s inland. The better plume of moisture arrives after sunset ahead of a shortwave pushing into the eastern Great Lakes. There continue to be considerable discrepancies amongst the guidance as to how far east into SNE the PWAT plume pushes, but ensembles are in agreement that the far better chance of wet weather will be over western MA/CT where the much more moisture is present and upslope flow into the terrain will enhance lift. The GEFS and EPS put the chance of measurable rain over 90% in western MA/CT and less than 30% in far eastern MA.

LONG TERM /THURSDAY THROUGH TUESDAY/

Highlights

* Isolated to scattered showers on Thu, mainly across the interior, with slightly below normal temperatures.

* Dry for much of Fri with temps returning to seasonable levels.

* Cold front brings scattered showers late Fri through Sat. Mild temperatures return.

* The temperature roller coaster continues, with a return to near normal temperatures and dry weather for Sun into Tue.

Southern New England will be dealing with another mid level omega block. This time through, we should initially be located beneath the ridge portion of this block. Currently expecting this mid level ridging to move off to our east towards this weekend, leading to a transition to a broad mid level trough early next week.

At the surface, high pressure should remain in control of our weather into Friday morning. Thus, mainly dry weather expected, although there could be a risk for scattered showers towards its edges, which would be mainly across the western half of southern New England both Thursday and Friday. A slow moving front Saturday should continue the risk for showers, before high pressure arrives late this weekend into early next week.

Stayed close to the NationalBlend solution for this portion of the forecast. Can see a scenario where rainfall chances could be lowered in later forecasts for Thursday and Friday.
