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

One of the nicest looking forecasts I can recall in recent memory. Heavenly Currently 65/55 under full sun. Picked up another 0.34" overnight.

Really?? I'll gladly take another few weeks with highs in the 70s

Wow. That's exceptionally high. Irradiance at the top of the atmosphere is roughly 1360. That's usually whittled down to around 1000-1100 due to humidity, aerosols, etc

It was so damn windy the annual Rappahanock Rivah Regatta had to stay off the water today. Sailboats. Too much wind in late May... when we're almost always concerned with too little. Lol

lol, things turned around quickly this evening. FFW warning through 10:30pm. Up to 1.24" at CHO

only 0.26" at CHO and we've got sun trying to peak through now

Got a solid first burn of the year walking around on a landfill and some cattle pasture in Albemarle today. Windows open now. Sucks that we're so dry but I don't hate this SoCal weather

Maybe the windiest day yet down this way. Pollen apocalypse out there. My eyes are dying

The skylight cover/window over the stairwell in my row house in DC was lifted off the building and disappeared into the sky that day. Pretty sure the pressure differential between inside and out during one of the gusts is what popped it free. Epic indeed.

this board's negative feelings about wind will never fail to amuse me. I love it. I wish we had more days like this

Not trying to be mean here but that article is trash. "10 times better?" Over what time scale? what variables? wtf does better even mean in this context? nothing is explained. That's an AI hype piece masked as a "the revolution is here!" feel good story Their "revolutionary" model has slightly lower RMSE values when compared to the GFS in most areas. It also runs at a 1.5 degree (~110 miles) horizontal resolution compared to the GFS's 0.25 (17.4 miles) or the ECMWF HRES's 0.1 (5.5 miles). Vertically it's also nothing close. The GFS divides the surface to the mesopause into 127 layers. The ECMWF has 137 layers. This AI model has 5. It's providing orders of magnitude less information about the atmosphere, and it's only slightly more accurate at the points it does forecast.

"Pot, meet kettle."

From the science perspective, that likely contains very high NOx and SO2 particulates compared to current levels. Peak poor air quality (from those two offenders) was around 97/98. NOx dropped off quickly after 2000 and SO2 was only a few years behind. We're down about 90% on those emissions since 1995. Some environmental researcher may be mildly interested.

Just about done here. One of the most visually impactful 2" storms in recent memory

Back end approaching quick down this way. This may end up my 2nd favorite event this year due to the temps. I honestly prefer a frigid 2-3" over a sloppy 6-8" type deal like we had last week.

Somewhere near 2" now in Charlottesville. 19/14, mod snow, 0.5 mile vis

Some nice banding setting up over Albemarle. Approaching an inch here but it feels like a lot more with the temps preventing any melting. Salt did nothing this morning, roads caved instantly and have stayed covered. 18/12, moderate snow, vis. 1.25 miles

Yeah well half the people on this thread were doing the same so not sure this place is much of a step up. I guess if you're ignoring anything that isn't from a red tagger or like 3-4 other accounts it's fine lol. Posting any NAM output that's over 48hrs needs to be banned on here, not even kidding. These weenies need to have some sense knocked into their head. Like you might as well be posting the results of a coin flip..

well that was impressive to witness CHO went from 39F at noon to 55F at 1:30pm

Boundary layer temps continuing to run well below forecast down this way 12z NAM3k @ 1pm - 57F CHO @ 12:25pm - 45F

whatever survives down this way is going to become concrete overnight Temps are also way down compared to forecast. the 3kNAM had CHO at 50F by noon and they've only managed to get up to 38 here at 11:30..
