Off and On Showers Today

A slow moving frontal boundary lies nearby and will gradually inch east through the region today.  Since we're on the damp and mild side of the front, temperatures are starting out in the 60's this morning and bands of showers are moving through the region at this early hour.  Radar up above is from 4:30 and shows a band of showers (with a lil bit of thunder embedded in) working northeast through the Delaware Valley, with scattered areas of rain across New Jersey.  This system will gradually lift through the region over the course of the morning, a break will ensue for the midday hours where a few glimpses of sunshine are possible, followed by a second impulse down across Tennessee working into the region for late this afternoon and this evening.

Since the frontal boundary will slowly inch east through the duration of the day, the late afternoon/evening focus of rain will be more likely east through south of the city than north through west...and we should see Jersey and Delaware pick up a steadier round of rainfall from the second impulse as it tracks through our region.  Round two's chances of rains will increase across the southern/eastern half of the region after 5 PM. That said, despite the better chances of rain being south and east with round two it doesn't eliminate Pennsylvania from shower chances this afternoon or evening either.

Highs today will get into the lower and middle 70's through the region, although a few 60's at the Shore are likely.  Those who get into any sunshine probably eek out the highest highs for the day...and as of now the best chances of that appear to be in the northern/western suburbs west into Central PA.  Reality may suggest otherwise but temperatures will vary slightly by location and by what premium of sunshine one spot receives.
