Series of Fronts This Weekend
Lined up like ducks in a row, a series of fronts are crossing through New England this weekend, which will eventually lead us to the promised land Monday. Seasonably cooler temps, sunshine and the feel of late summer or early fall! A front pushed through last night helping to trigger last night’s brief storms and downpours. Another front has been pushing through today. Clouds in place for much of the morning in SNE with scattered showers at the south coast. Even a few late day showers and storms along the front in western MA and N. CT. This slow moving front is finally pushing through tonight and off the coast by early Sunday. Skies will be clearing after midnight, with falling dewpoints and dry air in place.
Sunday morning will be filled with sunshine, but another vigorous short wave will be pushing into New England to help enhance lift and instability in the atmosphere. Clouds will be building by midday, with scattered showers and storms starting to pop during the afternoon hours. While most activity will be scattered, hit or miss, there will be a few brief downpours with the potential of a strong localized storm. A good chance of this exists across eastern MA where we could have a sea breeze shift in during the afternoon. This along with a breeze from the WNW would mean enhanced surface convergence right along the sea breeze front across eastern MA. Something to watch out for Sunday afternoon. Highs will remain in the 70′s to near 80, with sunny to Partly sunny skies and scattered showers or a storm in the afternoon. This upper level short wave will help to steer this front off the coast by Sunday night with seasonably cool dry air on the move with low dropping down into the lwr 50′s overnight! Refreshing cool air for this time of year.
High pressure will be over us Monday and Tuesday with picture perfect ideal weather. The high will be off the coast Wednesday, but close enough to allow for one more good day with temps near 80. A potent front will approach by later Wednesday night. Showers and thunderstorms are likely Thursday with locally heavy rain. A surge a slightly warmer air should follow in behind this front with WSW winds bringing temps back into the 80′s for Friday and Saturday
Another front will push through by next weekend with cooler air returning by Sunday August 11th. The upper level trough across Canada will be flexing it’s muscle and returning back to the northeast for a return engagement for the month of August helping to keep any heat and humidity away until at least the 20th of August. Incredible when you think about how downright hot August can be. Not this time.
