In case anyone wants to watch the lightning strikes. Seems like a cool website.

Surprisingly almost no lightning with those heavy showers west of the city, though the atmosphere probably was stabilized by the initial rain and it now being cloudy. 

 

It seems that that every day the severe storms have started to form directly over us then ramped up to our south and east. 

 

We we will probably see the watch canceled over our area in the next hour or two.

I noticed that as well. Do you think topographic enhancement had anything to do with it? Needing the mountains to get things going?

This incoming line is really losing its punch. Just some weak showers to roll through I think. Even the back end of the rain is shrinking. On radar it looks like it is racing to catch the leading edge.

This wet summer like pattern looks to continue all week. It's unusual though for the first half May.

I was hoping back in late April the folks talking about a flip to summer would be wrong, but so far this year the longer range guidance has done well with pattern changes.

Yeah, a lot of water predicted by the GFS. Looks like its showing some interaction with that tropical system down in FL too.

I would also guess this is fairly unusual for May? I don't follow tropical to closely unless I'm planning a vacation along the East Coast, or there is a shot at some remnants hitting us, so not sure how unusual this might actually be or how likely the GFS is just out to lunch.

Anyone smart enough to figure out what was the trigger this evening to cause those storms to go up?

The latest AFD from the NWS mentioned a weak short wave moving through this evening.

Because of the limited instibility, they felt the heavy rain would be isolated.

I'm just amazed that all of a sudden the cells popped up on what looked like a line and then stayed stationary. Crazy stuff. Areas south of downtown received 2+ in of rain in an hour based on radar.

The 511PA traffic cams showing flooding on Saw Mill Run.

The water is almost as high as the jersey barriers near Bausman. :o

Just took a peak at that cam. It does a live stream from it as well.. Crazy high water down there right now. Stay away if you can

I had just driven through there around 6:30, crazy stuff.

Can't find anything on twitter warning folks about the flooding. Very disappointing.

Painters Run Road is really bad. That creek has overflowed its banks and there are rock and mud slides from the hills. I got caught in it coming home. Avoid that road. I probably should have turned around but got through it. Just caught me off guard.

NWS Pit has 8 tweets over the last hour talking about the rain in the south hills. They also retweeted the Allegheny County handle. Maybe could have done a little more, but i think thats a pretty good showing.

Glad you made it through. 

Lots of roads around the metro are vulnerable to flash flooding and landslides.

After being on the NW edge of the severe weather last week, now we're on the SE edge. Lol

Although on the positive side, we tend to get better cell development with these type setups.

Not feeling too optimistic about the storms making it to us intact. Satellite imagry showing that the storms are having a hard time maintaining after they form. CAPE looks decent, but the aloft winds are pretty weak. I'm hoping to get some good thunder later tonight, but not holding my breath.

Looks like a nasty cell heading towards black and gold.
Yeah, it's getting dark rather quick here. Lots of lightning and thunder. The heaviest of it could dip just south of me but it's close.

How did you fare? Looked like so nice velocity reading around McMurray. I had great thunder and lightning some moderate rain but hardly any wind. I was just north of it.
