Soakers on Friday...Weekend Delight
After a fairly quiet Thursday with building humidity, we will remain quiet this evening as well...but not for long! Dewpoints are in the upper 60's to near 70 and that is where temps will remain overnight. Showers and thunderstorms are scattered, but they are gathering across NY, PA and the mid Atlantic states. Some of these showers and storms will begin to push into western new England during by dawn Friday.
A stalled front remains in place over the eastern Great lakes and Canadian boarder. On Friday this front will slowly begin to slide into New England and will become the trigger for lift that was missing on Thursday. Showers and embedded storms will push from west to east during the morning hours. I expect a dry early morning commute across Eastern MA around 5-7 AM, but rain will quickly be filling by 9 AM. By 10 AM we will be seeing heavy downpours, embedded thunderstorms pushing through which will likely last into the afternoon with the front still in western New England. Highs will hold in the 70's to near 80 Friday. By the evening commute, the heaviest rain will be winding down with the front pushing off the coast. Some areas could get upto .50-1.5" of rain as this all winds down Friday night. Showers may linger early, but quickly diminish during the evening hours with some overnight clearing. This front will break down the humidity with much cooler comfortable air to follow for the weekend.
Saturday will start off with a few clouds on the south coast closer to the front. Dewpoints will start off a bit muggy, but drier more comfortable air will follow in during the afternoon with mostly sunny skies and a drying warm west wind. After a mild start in the mid 60's, temps will quickly warm up into the mid 80;s by the afternoon. It's all gravy after that with building high pressure behind the front for the weekend with light WNW flow. Sunday will be sun-filled and a bit cooler, more seasonal with temps either side of 80 degrees. A light sea breeze will keep temps in 70's near 80 at the beaches. The sunny dry weather will hold into Monday before our next front arrives.
Tuesday will see more clouds than sun with the risk of scattered showers and storms. Behind this front will be another charge of cool dry Canadian air with temps running seasonally cool in the 70's with more Canadian high pressure to follow. The upper level trough across the northeast will strengthen and re-establish itself as the rightful owner of the August weather pattern once again! The trough should remain in the Northeast through the 20th, after the 25th we have a chance for a flatter flow to develop and some warmer temps to end the month going into September. By that time, you would have the thing the tropics would start to become more active. We will be watching
