PLEASANT WEATHER THROUGH THE WEEKEND !

The Delaware Valley and Mid-Atlantic Region will experience pleasant weather through this weekend. The cold front that brought showers and Thunderstorms to our area Tuesday night and early Wednesday morning has moved moved off shore today. Behind this front much cooler and less humid air will follow for the next 3 to 4 days. An H5 Upper Level low will position itself over Eastern Canada and The Northeast though Sunday. This will allow a NW flow, of cooler Canadian air, to prevail on a downstream flow.

High Pressure will slide south of this Upper Level trough and will dominate much of the Midwest, Great Lakes, and Northeast into the weekend.
A shortwave and re-enforcing shot of cool air, will move through the area Saturday Night as it rotates around the main trough axis. This could touch off a few showers and Thunderstorm, Saturday afternoon and night, but much of the weekend will be rain free.

So expect:
M.Sunny Skies and Clear Cool nights, for both Thursday and Friday, with Highs of 80 to 85 and lows 55 to 60.

Saturday and Sunday: P.Sunny with highs in the lower to mid 80's and lows near 60. A few showers and Thunderstorms are possible Late Saturday afternoon and evening, especially to the North and West of PHL.

Enjoy !
