Transitioning To Warmth
After a couple of unsettled days of weather, summer's warmth will build as high pressure aloft builds. Sunshine, some clouds, but warmer temperatures will take over for the next three days once we get through this morning's fog in Pennsylvania (visibility levels as of 4 AM down to 3/4 mile in Blue Bell, lower west of there in spots). Wednesday and Thursday will likely be warmer than today but all three days afford a more typical summery regime as our four week stretch of mainly cooler weather departs.
With the warmth, humidity will not be too much of a factor today. Dew points will be in the lower half of the 60's. Not bad and "typical" for summer.
There is a very low risk of a pop up shower or storm (a couple of the higher resolution models hinted at this yesterday but in last night's runs have since backed away from the concept) but odds strongly favor a dry day.
Highs this afternoon will reach the upper 80's for many of us away from the water, with highs near 80 at the Shore. Winds will be light from the west, gradually nudging around to southerly at the Shore this afternoon. This morning's fog should lift and burn off by 9 AM or so.
