Pittsburgh/Western Pa Weather


north pgh

Recommended Posts

Pretty Nasty MCS has formed in the Midwest, could reach us later tonight.

I am traveling north for the weekend.

I have been looking for some good thunderstorms and it figures that when I go away the chance comes.

You guys should be right on the edge tonight, better chance south.

Tomorrow may be a better chance for the entire area.

I hope I come home Sunday with something in the rain gauge (Just no damaging winds)

I think the severe part of it will slide south of us, but maybe we'll still see some rain out of. I hope.

Yeah, hopefully enough to take the edge off temp wise, and also put any little bit of moisture in the ground.

Seeing that squall line blast through Pgh metro would be nice, but the risk of losing power is worse.
