Philadelphia Weekend Weather For Sat 8/27 & Sun 8/28
Large differences today between the GFS and NAM for this weekend. The GFS has partly sunny skies and only a slight chance of showers through Sunday. The NAM has mostly cloudy conditions and and a high probability of showers on Sunday. Confidence in the forecast with such large differences is low. The GFS has not been too accurate with Katrina. The NOGAPS has done much better. My forecast will go with the NAM today.
The NOGAPS model, which accurately predicted Katrina crossing into the Gulph, now predicts a very strong Katrina to make landfall around Louisiana Monday morning and take its remnants further west before affecting us Tuesday into Wednesday with heavy rains.
Sat 8/27: Mostly sunny with occasional periods of clouds. High near 84. Increasing humidity.
Sun 8/21: Going with the NAM model here: Mostly cloudy with showers likely in the morning and thunderstorms a good bet in the afternoon. High 82. Humid. (Much more sun and drier if the GFS verifies.)
Jersey Shore: SSE winds will allow temps to be a bit cooler, but humidities on the increase. Otherwise, similar uncertainties exist to the Philadelphia Forecast.
