Wednesday Comes Close To A Record In Philadelphia

Several days of warmth are ahead of us this week as high pressure builds in an optimal spot and combines with southwest breezes at the surface to nudge the thermometer into to the 80's for at least two and perhaps as many as five days between tomorrow and Saturday.

Wednesday appears to be the warmest of those days, aided by some higher "heights" in the atmosphere building overhead thanks to a ridge of high pressure aloft in the atmosphere strengthening enough to allow for some additional warmth. The setup provides us a classic "torch" scenario where temperatures could make a serious run through the 80's...and perhaps make a run at a record high in Philadelphia and Atlantic City.

Records on Wednesday are aggressive in a few spots -- most notably Allentown (92) and Mount Pocono (89), with many of the records dating back to 1927. The Philly and AC records date "only" back to 2002 and on the list above, are arguably the "easiest" to knock out along with Millville's 86 degree record from 1952.

This scenario does not look like it will produce any 90 degree temperatures but I can see some spots hitting 85 on Wednesday afternoon. Our dry pattern of late, combined with mostly sunny skies and an optimal breeze direction, should give us enough fuel to get a very warm day around here. Wednesday, along with the balance of the week, will provide a bit of a final "hurrah" to the summer before a cold front passage late this weekend brings an end to the nice (and now warm) weather.
