Churning To A Slow Boil

The excessive heat warning remains for Wednesday and Thursday across the Delaware Valley, with a warm front lying to our west and southwest and ready to slide on northeast through the region today.  You'll notice a warmer and more humid look to the weather this afternoon as sunshine pops out and temperatures jump into the 80's away from the Atlantic.  Dew point values will climb into the 60's, making our transition to discomfort a bit more onerous.

While there's a chance of showers and storms around for this afternoon, there are a few showers lying across Central Pennsylvania this morning that are pushing southeast.  These showers are in association with a weakening MCS that developed in Wisconsin yesterday and pushed east through the Great Lakes.  While the brunt of the activity will stay to our north through the day, a few showers can't be ruled out this morning...and another chance of thunderstorms is in the cards for late this afternoon and evening as another MCS in Minnesota this morning pushes through the Great Lakes...a piece of that energy will try to scoot through here later on.   Not everyone will see thunderstorms but a few spots could get a few rumbles of thunder later on.

Today's warming will pale in comparison to the heat that much of us see on Wednesday afternoon as temperatures push into the middle 90's, with heat index values approaching 100.  Thursday still shapes up as the most intense heat day as temperatures push into the upper 90's...with a few optimistic bank thermometers cracking 100.
