Philadelphia Weekend Weather Outlook- Tues PM
For the next several days, a humid southwesterly flow will interact with a cool cyclonic flow aloft resulting in a recurrent chance of heavy showers and thunderstorms. This feature looks to be with us through late Friday night.
Yesterday, it appeared that things would clear out for the weekend, but the latest GFS has the same afternoon showery weather returning on Sunday. Much uncertainty with the timing and details at this point, but right now, Saturday looks like it will be the better of the two days.
Just as we saw this past Sunday, most of the day turned out quite nice and the degree of showers was over-estimated. The same may occur for the coming days and weekend.
Sat 8/1: tentative: Cloudy early, then mostly sunny very warm and humid. High near 90.

Sun 8/2: tentative: Partly sunny, showers and thunderstorms in the afternoon. High 90.

Solar- Climate Comment- Updated 07-28-09: The visible sun is again spotless. There is a bit of increased solar activity rotating into earth view. Solar activity remains relatively quiet and solar flux remains low, at 68.4. We will remain in an climatically cool weather pattern for the summer, as solar flux and total solar irradiance are at extreme lows due to an anomalous nadir in the the sunspot cycle. Continue to expect a cooler than normal summer on average and this pattern will likely extend well into the fall and winter. We may have a record cold fall and winter this year.
