Warming up

Temperatures along with the humidity will be climbing through the middle of the week.

Today:  Partly to mostly sunny, very slight chance of an afternoon shower or thunderstorm, highs in the low to mid 80s.

Tonight:  Mainly clear, lows in the low to mid 60s south, near 50 north.

Tomorrow:  Partly sunny, again the slight chance of an afternoon shower or thunderstorm, hot and humid, highs near 90 south, upper 80s north.

Tomorrow night:  A few clouds with areas of fog toward dawn, lows in the low 70s south, upper 50s and low 60s north.

Thursday:  Partly sunny, hot and humid.  Afternoon showers and thunderstorms possible, especially north of the Mass. Pike, highs in the low 90s south, upper 80s north.

Discussion:

The Eastern United States is under the influence of a large area of high pressure.  This is provide pleasant conditions to the region.  Over the next few days this will shift off shore.  As this happens our winds will turn around to the southwest and this will pump hot and humid air into New England. 

Today will be our last comfortable day before humidity levels jump up.  There will be a bit of upper level instability that will pass over New England this afternoon.  This may help to set off a few isolated showers or thunderstorms this afternoon.  However the lack of any significant moisture at the surface will severely limit this activity.

As we head into the tomorrow, temperatures will climb on the back side of that high pressure system and ahead of an approaching cold front.  This front won't pass through New England until Thursday afternoon.  It might make it close enough on Wednesday to set off a few showers and thunderstorms across the interior of New England on Wednesday afternoon, but again this activity will be very spotty in nature.  Thursday will be our best chance of showers and thunderstorms as it looks like the cold front will arrive in the afternoon.  Hot temperatures and high humidity will add fuel to the cold front and as a result some of the thunderstorms could be severe with high winds and large hail.  Since tornadoes are on every one's mind I feel obligated to mention them in some way.  Right now it's a bit too early to determine if conditions will be right for tornadoes to develop, should know more tomorrow.

Enjoy the warmth and thanks for reading!
