Our climo doesn’t seem to allow for many days in that 85-95 range with comfortable dews once you get past about mid-June. Maybe a few in the low end of that temperature range. Yep. It is either 75 and comfortable or 85+ with 65-70 degree dewpoints…and really where are we going to get a dry hot airmass to come from…most of the time that we have 85+ das it is due to SE ridge pumping in an airmass directly from the gulf. Also, I’ve been out west, and will take 95 and 40 degree dewpoints over 85 and 70 degree dewpoints any day of the week. Link to comment Share on other sites More sharing options...

I'll take low 60 dew points with those temperatures. It's really not that bad, but as we climb near 70 for the dp, then there are problems.

donyewest Posted June 21, 2021 Share Posted June 21, 2021 Did some lawn stuff and put grass seed down early this morning hoping for a good rain up here little north of Butler and the driveway barely ended up wet. Everything went north and south of us. Link to comment Share on other sites More sharing options...
north pgh Posted June 21, 2021 Share Posted June 21, 2021 Rain pounding here. .56 so far. Winds haven't been too bad. Maybe 45 mph gusts. Flash Flooding may be the new threat as storms training a bit. Link to comment Share on other sites More sharing options...
jwilson Posted June 21, 2021 Share Posted June 21, 2021 Looks like this one weakened below severe levels right before it hit us. The wind wasn't even that bad locally. Hopefully no tornado up north. I had a good view of the line from the southeast and there might have been remnants of a wall cloud, but it became clearly disorganized before moving in. Also didn't visibly see any real rotation.

north pgh Posted June 21, 2021 Share Posted June 21, 2021 Rain is easing up a bit. Picked up .76 inches of rain. A few cloud to ground strikes still around. Keep alert over in Eastern Ohio. HRRR showing a possible second line developing and moving through the metro area in the next several hours. Link to comment Share on other sites More sharing options...
heathaze Posted June 21, 2021 Share Posted June 21, 2021 I wish the NWS would go back "old" radar page. I know it's a change in technology that brought about the upgrade, but the previous presentation/display was better. (FWIW, I've used a radar app ever since this change went into effect. (Weather Hi-Def Radar)) Link to comment Share on other sites More sharing options...
Ahoff Posted June 22, 2021 Author Share Posted June 22, 2021 These training storms are absolutely disgusting. Some of my least favorite weather. Just won’t stop raining. This front or whatever just needs to drop down. Link to comment Share on other sites More sharing options...
KPITSnow Posted June 22, 2021 Share Posted June 22, 2021 These truly might be the two nicest days we have until September. By the time the weekend rolls in we will be back to mid 60’s or higher dewpoints, but today through Thursday really are going to be spectacular. 1 Link to comment Share on other sites More sharing options...

Honestly this annoys the hell out of me they came out to survey this when the damage from last week’s storm was much worse and they ignored it. They said they don’t usually survey microburst damage, which I find to be very unlikely. 1 1 Link to comment Share on other sites More sharing options...

Not to be cynical, but do you think the fact that 6 trees got uprooted next to a playground where rich people’s children play had something to do with it?

Doubtful. More like they had put out a warning and wanted to confirm their warning was correct. Will say that If you look up their language on when they do surveys, they do say they survey microbursts to see if their might have been spin ups and help them better understand those events. I know it’s dumb but I could almost guarantee there were greater than 70mph winds in the north hills last Sunday. Link to comment Share on other sites More sharing options...

RE: the first bolded point, I agree that the tornado warning and “possible tornado” probably had much more to do with the decision to survey than anything else. My comment was meant somewhat facetiously. RE: the second bolded point, I absolutely concur. We didn’t get slammed in my immediate vicinity, but I live in the north hills and I’ve driven through parts of McCandless and Hampton several times in the past week and the tree damage seems to be a bit more than your typical low-end severe thunderstorm.

What are your thoughts on why there was not a survey sent out? It seemed incredibly odd give the amount of damage especially in north park and near wildwood. You can’t convince me there weren’t 80-100mph winds in those storms. Link to comment Share on other sites More sharing options...

The heat signal for next week looked good with a lot of model agreement yesterday. Now there’s model agreement in the opposite direction (except for the Euro to some extent) with the ridge shifted way east. The weather app is always a good litmus test for this, and it doesn’t look good for what you want to see. Link to comment Share on other sites More sharing options...

I'm not really sure if there is a difference between how tornado damage and straight line damage look? Possible they could just tell based on radar that there was no spinning?

Possibly…but usually straight line winds over 70mph outs side of a massive derecho are pretty rare. We rarely get the type of damage we saw without there being a microburst. Also I believe straight line winds often have a lot to do with storm forward momentum, and these ones were crawling. Link to comment Share on other sites More sharing options...

But yes, a wide range of possibilities for the first half of next week depending on where the western Atlantic ridge sets up. And one of those possibilities includes a chance of reaching 90.
