Here comes the front

Heralded by a frightening and darkening skies, a nasty line of thunderstorms is pounding parts of the northern and western suburbs.

Heavy rain and thunder were reported from Pottstown to Conshohocken. At last look, the sound and fury was heading toward the city.

Here is the latest radar image.

But this could be it for the reign of rain, and once this front goes through, it will start turning cooler.

Overnight the official temperature in Philly could go below 60 for the first time since Sept. 20, and it may struggle to reach 70 tomorrow.
