[su_note note_color=”#d9f2da”]Friday 8 AM update: The front has slowed. Clouds had been expected for much of Friday, but it appears that areas of showers may linger into the afternoon in some areas. This had not been forecast.
It suggests the models don’t have a good handle on the forecast for the weekend. I’ll update this evening. [/su_note]
A cold front will move through tonight (Thursday) and a line of showers and thunderstorms is predicted by most models between 9PM and midnight. Some of the thunderstorms will have heavy rain Thursday night and 2-3 inches of rain are possible in the immediate PHL area. Areas west and north of Philadelphia are showing high shear values, so some thunderstorms will likely be severe.
High pressure builds in for Friday and the weekend. Unfortunately this high pressure center will remain to our north and an easterly or northeasterly flow of air may bring some damp conditions to the Jersey shore on Sunday, according to the latest NAM.
Most of the area will have sunny skies, but periods of some fair weather cumulus clouds are possible as well. A delightful weekend is forecast weather-wise.
High temps Saturday 77, and Sunday 76 with low humidity.
[su_note note_color=”#d9f2da”]The easterly wind flow needs to be watched. This sometimes results in more cloudiness than the models predict this time of year. Sunday may have more cloudiness than currently forecast.[/su_note]
