Discussion
Current radar shows our showers moving through. Some of the ones further south may have some rumbles of thunder with it
And then our sea level pressure over the northeast. We see slow moving cold front dragging through Indiana/Ohio border and then a warm-ish front trying its darnest to muster up some strength in the Delmarva peninsula.
Latest WPC product from a few hours ago (1045z – 645 AM) shows these features as well, with the cold front a little farther west as this image is not as up to date as the one above.
Current temps in the immediate Philadelphia area are as expected, high 50s to low/mid 60s.
Where do we go from here…
NAM model for around 5 PM this afternoon
So our warm front has pushed through New England by this time, some showers remain through the area. Cold front is making its way through W. Pa.
By 3/4 AM the cold front will push through Philly. We may have some rumbles of thunder as the line pushes through, particularly out in C. Pa.
Meanwhile, temperatures…..might sneak to 80 degrees in the immediate Philadelphia area, otherwise upper 60s to 70 to the north and west
All in all, not a soaker of a day, but it would most certainly be a good idea to keep the umbrella handy.
Tomorrow the cold front will slide through during the early morning hours, leaving the rest of the evening comfortable, cool, and not too wet.
Air Quality:
Current air quality is mostly clear! Expecting the rain to keep things down most of the day.
The AQI is based on a scale of 0-500, with 0 being no issues and 500 being very hazardous to everyone and an emergency condition overall. Today we will be between 0 and 50, so generally fine for all people. A patchy area of moderate air quality exists this morning in Delco and up near West Chester, but that isn’t expected to last the whole day.
