Maybe you should read his posts a little closer before spitting out knee-jerk reactions? It's either that or you are really bad at geography. Calling WV a "western" state that has "nothing to do with the area" is a complete head-scratcher. Harper's Ferry is 40 miles from the DC line

The irony of a PA poster saying this in the MA forum lol.. come on

Still under 80 at CHO. The filtered sun is really holding temps down

Studying the paths of those two is pretty interesting. TC #11 formed directly in the wake of the other MH in that pair (#8) with only two days of separation. Worth mentioning that TC 9 and 12 also formed in the same general part of the Atlantic within that roughly 2 week period at the end of August. There must have been some seriously favorable conditions.

From yesterday. I know it's hr 384 but it got my brain going. Is there any historical precedent for what's shown, two sub 950mb canes approaching the SE simultaneously?

There's a reason farmers would get up at 5am to start their day. Working in the mid-day summer sun was avoided if possible southern europe has/had similar behaviors. Siestas/riposos were a midday break to shut down your business, go home, and/or rest. Typically in the early afternoon

this would get more traction in the Philly subforum. We cut off hard at the M-D line in here, only a handful of regular posters north of that

It's been impressively humid. I haven't seen the DP much below 70 for about two weeks now

Idk if all of that can be assumed from that data.. too far apart geographically for those temperature deltas to be attributable to ONLY the sensor accuracy and/or local environment effects. The weather in Baltimore (MD Science Center) and DC could be very different (or anywhere else for that matter). Especially in a month where backdoor fronts can easily cause a 30 degree temperature delta between NoVA and the M/D line. You need to be looking at other stations within like 5 miles of DCA to make that comparison mean much

brief echo tops around 55-60k ft on that cell West of Carlisle, PA

Interesting afternoon down this way. CHO was well on it's way to 100 it seemed but the storms that popped early over Madison and Orange counties sent a bunch of outflow and high level clouds out to the SW. We've been in the mid 80s since ~2:30 because of it despite zero precip

Downtown Charlottesville hit 100 right around 4:15, back to 99 now. (WVIR Earth Networks Station) Temps outside of town hovered around 95-96 most of the afternoon. CHO's garbage weather station hasn't reported since 2:05pm.... right in the middle of a significant weather event again. It's like they do it on purpose, it's honestly baffling how often that station goes offline.

I was curious about that as well so went and snooped around in Google Maps. Seems like the stuff coming off the roof was just from the roof itself sending all rainwater to the new low spot after the wall failed. This is a pretty good example of older construction that likely wouldn't get permitted today (at least not in VA). You're right that the building was effectively a dam... look at where it's located in the local landscape. Red = apartment building, Teal = drainage area The uphill side is basically a swimming pool too, with the curb likely not high enough to contain the water in the street from spilling over. Drainage for the lot seems to be a grate drain (teal rectangle) and an ~18" overflow pipe (teal dot) going under/through the building. Both could have been partially clogged, especially the grate. Really poor civil design here overall.

My memory from the last few summers is most models have been overdoing high temps in the med/long range. I'm guessing we top out around 96-100F for most of the area.

I gave in, I turned my heat on. 54/53 with mist and fog in hooville
