A Gradual Warm Up…Before The Midweek Showers
High pressure remains parked off the coast tonight with the big blocking ridge remaining firmly in place over us through Tuesday. Clear skies and light winds tonight will see temps drop back down into the 30’s overnight. A touch of frost was found in many cooler low lying spots this morning from Keene to Orange to Bedford, Natick, Norwood and Taunton this morning, along with some patchy dense fog. I expect a similar occurence this evening with lows dropping to the dew-point for patchy fog to form overnight, and even the chance of a few ocean stratus clouds backing into SE MA with light SSE winds at the surface especially after midnight
Any early morning marine clouds will burn off by 10 am for sparkling bright and sunny Monday. Warm temps in western new England will shift a bit farther east with more of a southerly wind at the surface. Highs will be in the mid 70’s in the N & W. Near 70 across Metro west, and even the coast will finally start to feel a bit warmer into the Lwr 60’s. Still a light SE flow will still provide a seabreeze at the coast during the afternoon
The warming trend will continue into Tuesday with most areas in the Lwr-mid 70’s. In northern and western New England..temps will feel summer like with highs near 75-80. Skies will sunny to partly sunny as some clouds will begin to increase and stream up the coast ahead of the upper low which has been stalled in the breadbasket of the nation for the past week. The blocking pattern and upper level ridge will finally begin to break down and door will be open for the upper low to drift and meander right up to New England.
As clouds increase and thicken Wednesday, cooler temps will prevail but enough mild air will be in place to keep temps in the 60’s to near 70…warmest north. Rain should begin to spread into SNE by the afternoon with showers lingering on and off into Thursday with the upper low sitting right over us. Temps will continue to cool with onshore winds and cloudy damp conditions down to near 60 by Thursday. The upper low will be lifting out on Friday, but there will still be a few periodic showers which will last into next weekend as a cold front will be pushing through. Another significant batch of rain could come with this which will eventually transition us into a cooler period once past the 13th. By the time the rain will be ending Sunday…many of may pick up 1-2″ of rain in a 5 day stretch of weather which will be much appreciated.
There is another significant shot of cold air which come barreling in from Canada into the Plains and Great lakes and swing into the Northeast around the time of the 13-14th. It is amazing what a struggle it has been for the midwest to warm this spring. It has been a year without a spring so far! This will be winter’s final cold shot. This Cold airmass will have to be tracked. Any moisture which interacts with it will be cold enough to snow especially in higher elevations..but it does not look like much at this point…so we will see. Enjoy two stellar days with a warm up before a period of some wet unsettled weather arrives.
