Fall-Like Feel Tonight
Posted by Chris Lambert
Before we get to the cool weather overnight tonight, we do have to track a few scattered storms in here late in the day and early this evening.
As a broken line of showers and storms move from the western half of New England, east, our chance for a passing shower or thunderstorm lingers until 8:00PM. While the threat for severe weather is limited, a couple of the stronger thunderstorm will be capable of producing brief, but heavy bursts of rain, wind gusts to 40mph, pea size hail and frequent lightning. Since the storms are scattered, not all towns will see rain, about 40% of us get wet through the early evening.
Once the sun sets, we lose the daytime heating and the instability that drives these storms. With a cool northwest flow overnight and clearing skies, temps tumble by August standards. While we likely won't break the record low of 54 in Boston tomorrow morning, my forecast of 58 is plenty cool for this time of year, and many of the suburbs reach the upper 40s and lower 50s by daybreak! Sure, it'll be a nice evening to keep a window open and let fresh air in once the storm threat passes, but by morning, the house may feel quite chilly.
Low humidity, sunshine and September-like weather prevail through Tuesday before Wednesday returns some humidity, and eventually some rain at night. Thursday may be a washout with rain and thunder through the day. Some of that rain could linger into Friday before another mainly dry weekend sets in for next week.
