north pgh Posted July 29, 2011 Share Posted July 29, 2011 Pretty dark just to my north, the original cluster has backbuilt another nasty cell. Looks like both north pgh and meatwad could get nailed, might even clip me also. This has been a bad summer for me for thunderstorms:( (bad luck) I hadn't had a decent storm since mid-May and last week while on vacation my neighbor said we had 2 bad ones. Tonight...I have a work meeting downtown until 8:00. (not a drop of rain in the city) I come home to 1.82 inches of rain in the gauge and was told I missed a nice lightning storm. Ross Park mall lost power and had flooding in the lot for a while. It's kind of like in the winter when you are out of town when the big snowstorm comes.

I didn't see a drop of rain here. Well, I think I got a few drops, come to think of it, but that was it. I could see looking at the radar yesterday that the North Hills and Monroeville were going to get hit hard and they certainly did. Link to comment Share on other sites More sharing options...
CoraopolisWx Posted July 29, 2011 Share Posted July 29, 2011 Out of the whole event, I got about 2 minutes of rain. But the lights went out twice... It's like the ohio river was a force field, all three storms grazed the river. lol This has been a bad summer for me for thunderstorms:( (bad luck) I hadn't had a decent storm since mid-May and last week while on vacation my neighbor said we had 2 bad ones.

Mabey a nice meso or tropical remnent will make it's way through next month. I'm watching one fire up just to my east right now. I'm near the Allegheny Arpt......actually, just checked the radar and it doesn't look too impressive. It got dark all of a sudden but I guess it was more bark than bite.

meatwad Posted August 1, 2011 Share Posted August 1, 2011 We got the 13th 90+ day of the year so far, today's high was 92, pretty hot for being behind a "cold front" We also got the 9th 90+ for July, and it looks like we're going to tie with July 1988 as one of the hottest July's on record. Looks warm to hot this week as well. Hot summer of 2011 continues. Link to comment Share on other sites More sharing options...
OHSnow Posted August 1, 2011 Share Posted August 1, 2011 July finished at 76.9 in Pittsburgh. This is tied for the 12th warmest, but all of the years that were warmer were from 1934 or earlier when records were taken downtown. The downtown station tended to run close to 3 degrees warmer than the airport locations. Official records were taken at Allegheny County Airport beginning in 1935 and at PIT beginning in 1952.

north pgh Posted August 1, 2011 Share Posted August 1, 2011 That latest cell that popped up and is moving into Westmoreland County looks pretty nasty. Look like it is going right over my old stomping ground of Harrison City. I'll bet some pretty large hail based on radar images. Anyone out that way confirm anything yet?

north pgh Posted August 15, 2011 Share Posted August 15, 2011 Finally got some much needed rain for the browning grass. Just a little downpour that lasted no more than 15 minutes but picked up .22 in the rain gauge. I have a feeling today will be the rain day on the back end of this slow moving low. Temp is a nice cool 66. Link to comment Share on other sites More sharing options...
