Unsettled Friday Leads To A Marvelous Weekend
There are not many mornings where we are tracking severe weather, but today was once of those mornings. Severe T'storms have been tracking mainly south of the MA Pike. They have been loaded with heavy rain which has producing brief periods of urban flooding on the roadways, along with the lightning and small hail, and some gusty winds.
With a stationary front along our south coast, a moist humid flow has been backing in off the water with light SE winds allowing dewpoints to climb back into the 60's, while much drier and more comfortable air remains across northern New England. Most of the shower and thunderstorm activity will remain in southern new England today. Closer to the proximity of the front and also axis of greatest instability and lift.
This first batch of rain/thunderstorms will finally be winding by late morning/midday. Still the atmosphere will be ripe for more scattered cells and storms to pop up in the afternoon. There should be a little bit of a lull once this first round pushes off the coast for the afternoon. Highs in the Lwr-mid 70's
A wave of low pressure back in the Ohio Valley will ride along this stalled front later today and tonight and track along the south coast. Scattered showers and thunderstorms will push back into western New England around 4-5 Pm and overspread much of southern New England with showers and thunderstorms for the evening hours through midnight.
The Low will be quickly be pulling off the coast Saturday morning with winds shifting to a drying downsloping NW wind. Clouds may linger a bit at the coast during the morning...before giving way to increasing sunshine and Partly sunny skies. Saturday will be a warm day with highs climbing into the mid 80's inland, local seabreezes should keep it a tad cooler at the coast. Dewpoints will be in the 60's for the morning...but fall off into the 50's by sunset for a gorgeous Saturday evening.
High Pressure sits over New England Sunday. Light winds will allow a seabreeze to develop keep most coastlines in the 70's while inland it will be in the lwr 80's with sunny very pleasant conditions. 850 temps drop off a bit Sunday compared to Saturday...so I am expecting a slightly cooler more comfortable second half to the weekend.
High pressure will slide off the coast late Sunday and begins to wrap in warming SW winds for Monday with highs back in the upper 80's in spots near 90. A cold front will approach Monday night and Tuesday which could trigger a few scattered storms as the front slows over us. Humidity and heat should remain with us through Tuesday before strong high pressure builds in for the middle to end of the week providing plentiful sunshine with low humidity and seasonal temps near 80. Fair weather cumulus will be likely during the afternoon with the cooler air which will be moving in aloft and dropping down to 8 C. Still once this Canadian high slides off the coast...another warm up will be on the way heading into next weekend.
