Weekend storm

Weatherbug says 2 to 4 inches in total, over tonight and tomorrow, in Mt. Lebanon, just south of Pittsburgh in Southwestern Pennsylvania.

Accuweather also says storm total 2 to 4 inches.

Annoying, but hardly the brutal assault expected elsewhere.

It looks like the whole of the Chesapeake Bay area will get the worst of it.
