Summer Makes A Comeback

After spending the entire month of August below 90, and now a renewed autumnal feel to the air into early September, it is easy to think this Summer is going down easy. Quite the opposite when you look across the idle part o the nation where most of the Midwest had highs in the 90’s to near 100 degrees today. We will briefly be tapping into this airmass, before we get back into the cooler air once again by next weekend.

Cool Canadian high pressure sits over us tonight with diminishing wind, dry air which will set the table for ideal radiational cooling overnight. Lows will drop into the Lwr-mid 40’s in most suburbs, with even a few 30’s in the colder sheltered NW valleys. No frost is expected. A chilly start at the bus stop Monday with clear skies. Once the sun gets a little higher in the sky it will turn into a sparkling day with highs in the upper 60’s and Lwr 70’s inland as winds shift to SSE in the afternoon with some increasing high clouds late.

The leading edge of the warm humid air will begin to push eastward Tuesday. Clouds, along with a few showers are possible Tuesday morning ahead of this warm front which will push through by afternoon with winds shifting to SW and highs climbing to near 80 with increasing humidity. Brighter skies will be more likely by afternoon. The Heat will be on Wednesday with bright sunshine and warm SW winds. Highs will climb into the Lwr 90’s, with temps cooler at the beaches. The heat will come with humidity with dewpoints in the lwr 70’s. A risk of a scattered shower or storm late in the day in N & W New England. This will be a great beach day and a day to plan to stay cool from the heat. This heat will sneak up on those not paying attention to the weather!

A cold front will be sweeping through on Thursday which will still be quite warm and humid with temps in the 80’s and dewpoints near 70. Showers and storms will be most pronounced in the afternoon and evening and come with some heavy downpours and the potential for some strong to severe storms. Some of these may impact the Thursday evening game at Foxboro. Lingering showers at the coast all the way through early Friday at the coast, before building high pressure from Canada will once again return to provide unseasonably cooler air for the weekend with temps in the 60’s for Saturday and near 70 for Sunday.

There will be a strong upper low moving through New England next weekend which will help to provide for some upper level instability. A cool mix Sun and clouds is likely…with the risk of a pop up diurnal shower. Also with another upper low could dig into New England to start off the following week which could also slow any potential warm up for New England…but a quieter flatter flow will eventually develop to the Jetstream which holds some promise for a bit more warmth to head our way before the month of September is over.
