Clouds are increasing ahead of a cold front with skies becoming mostly cloudy. Breezy balmy SW winds in place for Monday will bring temps from the 60’s this morning to near 70-75 by this afternoon with gusts to 20-30 mph. Dewpoints will climb into the mid 60’s making for a more muggy feel to the air. The breezy conditions will help to ease the comfort. As the cold front approaches, showers will begin to push towards western and Southern New England by the later afternoon. The showers will push west to east tonight with briefly heavy downpours, gusty winds and maybe an embedded thunderstorm. A weak wave of low pressure will develop on this front which could help to enhance the lift and precipitation. Most of the showers will be winding down after midnight.
With the cold front off the coast Tuesday morning, any early clouds will give way to increasing sunshine. Breezy drying NW winds will steer in a cooler airmass with high temps mostly remaining in the 50’s to near 60. Fair weather strato cumulus clouds will likely pop with the cooler air aloft.
High pressure to our SW will begin to build towards the east coast thank to an upper level ridge through the midweek. I expect an absolutely marvelous midweek with sunshine and warming west winds which will bring temp back into the 60’s Wednesday and maybe even the Lwr 70’s by Thursday. Nice to see this warm air return after Friday night’s early season frost. This warm up after the widespread killing frost could be considered Indian Summer weather if you are wondering. The unseasonably mild weather will last to the end of the week, but we will be tracking more unsettled weather towards next weekend.
A big upper low will be sliding into the northern Plains. through the Great Lakes before finally pulling away from New England by Sunday. As energy moves around the base of the trough across the east, moisture will be directed up the east coast ahead of a cold front which will come with a period of heavy rain. There are some questions with the exact timing of this rain. One model has a wet Friday with a drier weekend. The other has a developing wet Friday which lasts all day into Saturday as a slower solution. Either way, it looks like there will be a period of wet weather to kick off the weekend, before drier weather should settle in by Sunday
