An Amazing Weekend of Sun...With Some Important Subtleties
Becoming a Familiar Pattern: Mild to Warm and Back to Mild

Incredible Summer Heat on the First Day of Autumn

FRONTS_D1Incredible warmth continues for one more day in New England, regardless of the autumnal equinox at 3:50 this morning, heralding in fall.  Instead, a gusty southwest wind will exceed 30 mph at times, continuing the transport of downright hot and humid air across New England, where morning temperatures in the middle 70s as far north as the Crown of Maine will translate to widespread 80s to near 90 Monday afternoon.  With dew point temperatures – the measure of the amount of moisture in the air – reaching the 60s to near 70 in Central and Southern New England by day’s end, heat index values or “feels like temperatures” will exceed 90 degrees.  Hydration and avoiding overexertion will be important for one and all, but particularly for kids on the practice and game fields Monday afternoon.  Scattered showers in the North Country Monday, well ahead of an approaching cold front, will slowly expand south and east, mostly gaining traction between 6 and 9 PM, then intensifying over Central and Eastern New England Monday night with some embedded downpours and thunder.  By Tuesday morning, the cold front will be through most of New England, leaving only early morning rain on Cape Cod and in Eastern Maine that will depart quickly, but the upper level atmospheric energy driving the cold front will still need to move through the sky above, prompting blossoming clouds by midday Tuesday after morning sun, then blossoming showers with embedded thunder in pockets Tuesday afternoon.  Tuesday night and Wednesday, fall air will mean dry conditions with a clearing sky and the next disturbance delivering scattered showers won’t arrive until Thursday evening or night and should move through quickly, leaving a fine fall Friday.  The weekend is likely to bring another swing from mild to cooler air from Saturday to Sunday with a cold front marking the transition between that air Saturday night, though the timing is yet to be nailed down and will determine exactly when potential showers, if any, would move through before more great fall weather early next week in our exclusive First Alert 10-day forecast.
