Tuesday's strong wind was cooler air moving in from Canada and the summit of Mount Washington gusted 128 mph with steady snow. Very impressive for this time of year.
As for Wednesday, the Canadian high-pressure center passes right over our head, that means much less wind. Under mostly sunny skies, high temperatures get to 70 degrees inland, with a weak sea breeze developing. It's a bit cooler at the coast. With a mostly clear sky, and dry air Wednesday night should be chilly with lows in the 40s and 50s south, 30s and 40s north.
The weather system responsible for the heavy late season snow, and the Midwest severe weather outbreak, is weakening and moving toward Canada. A warm front well ahead of the system will cause clouds to increase here Thursday night, with low temperatures in the 40s.
A few showers are possible Thursday as clouds get thicken, but it’s not a bad looking day. High temperature will be in the 60s. Late day however, thunderstorms are likely and may become strong to severe in Pennsylvania and New York.
Those storms will enter western New England around sunset. As night falls, we are all vulnerable to a downpour or period of rain Thursday night. There could be some damaging wind gusts with some of the storms.
It’s warmer and more humid to start Friday, but the air should dry out in the afternoon as wind increases from the northwest. Low pressure is taking an unusual track from northern New Hampshire, toward the southeast, into the Gulf of Maine.
A continued sign of blocking in the north Atlantic, that has resulted in the rather repetitive weather pattern.
Maybe we can break the streak of wet Fridays, but it’s going to be like threading a needle, with the front to the east in the front to the west. For now, we'll forecast a mixture of sun and clouds with a chance of a shower and a high temperature close to 70 degrees.
As for our streak of sunny Saturdays, we may keep that going with a mixture of sun and clouds. Another front will be coming at us with a chance of showers or thunderstorms late in the day and at night.
It’s pretty much a continuation of the same thermal gradient we’ve been watching for weeks now, and the closer we are to the front dividing warm and cold, the more likely we get wet. The next wave of energy may come in Saturday night and hopefully move out Sunday.
The early call for the second half of the weekend is for dry Sunday afternoon into Monday morning. Then another wave of energy that may bring showers and thunderstorms later Memorial Day afternoon and at night. We probably end up on the warm side with temperature is climbing to the 70s and 80s early next week.
