Clouds & Cool Win The Next Few Days
There is a deep trough in place in the Eastern US. It extends into the gulf of Mexico. This trough is directing cold air all the way down to the southeast where some states will see their first frost of the season. These Upper Level winds are steering clouds and moisture from the tropics right up the Eastern searboard into New England today. A cloudy cool overcast kind of day can be expected with temps remaining in the 40′s with cool NNE winds which are helping to push away any sort of warmth left over from yesterday.
The best chance of seeing any sun today will be in western New England where the clouds could thin just enough by the midday-afternoon for a little partial sun. Eastern New England is stuck in the clouds. There is a chance the coast could see a few sprinkles, with the best chance of a few light showers mostly on the Cape & Islands.
High astronomical tides and the recent passage of a storm which brought 1-2″ of rain is making for some lingering rough surf and an above normal midday tide today. Splash over for eastern facing beaches from Portland to Plum Island to Scituate and Chatham from 11 AM-1 PM today.
The steady flow of clouds will continue into New England tonight through tomorrow…especially cloudy at the coast. High pressure to our west will be just close enough to supply enough dry sinking air to allow for clouds to continue to break inland…so that by Sunday…partly sunny skies will be found inland with lingering clouds at the coast. Cool onshore winds will keep temps in the mid-upper 40′s
Energy rounding the base of the trough will link with energy coming out of the tropics to help to slow and deepen the trough over New England. A wave of low pressure will form and back into the Gulf of Maine Sunday Night before looping back into the coast…then pulling away Tuesday and heading back out to Georges bank. This low will likely come with a period of rain Monday before tapering off to Drizzle Tuesday.
An upper level ridge will begin to shift eastward during the midweek. This will help to kick out the trough and restore stability to the atmosphere…with increasing sunshine and above normal temperatures into the Lwr 60′s by Friday.
