Yup, saw this all the time when I lived in AdMo/Woodley Park (roughly 175' asl) and worked on L St. Lots of marginal events where I walked to work in snow boots because of an inch or two of slush in my neighborhood, only to take the metro downtown and the sidewalks were bare. There were even a few events where that ~125' difference was enough to turn it into a wintry mix from all snow. Lots of tall buildings covered in materials that like to hold onto heat will do that!

Can't remember the last time we had air this dry. 45/-2 at CHO. That's 14% RH... EDIT: now 45/-4 at 1:40pm. 12% RH

Radar sure looks snow squally up near the M/D line

By far the best fall colors in recent memory for me. The Charlottesville area is stupidly gorgeous right now, it looks like Northern NE around here. Drone shot below from this morning

Not even close to cold enough up top. Freezing line was up around 700mb at 8am this morning. 850s were in the low to mid 40s.

It's so dark in Cville right now that street lights are coming on 72/69 with rain switching between moderate and heavy

Today has got to be one of the weirdest weather days for August I can remember. This little area of convergence has been stuck over the Staunton -> Charlottesville corridor for more than 12 hours now. Didn't make it above 70 until 11am, then only made it to 73 for a high. I think we'll be back into the 60s well before sunset. We've picked up about 0.5" since midnight.

I hope we get this weather straight through October every year

What causes that to be so prevalent today?

65 dbz pixels on the cell West of Charlottesville

This morning's HRRR runs really missed on the convection in central VA right now. Moderate rain and a few rumbles of thunder in Cville the past 30 mins. 82/76 at CHO. swampy.

Right, with a 75 degree DP it needs to be about 95-100 to hit a "comfortable" humidity level and then the heat index is like 105+. I'll take 85, overcast and swampy every time.

Not when the dewpoint is 75

This main cell over Cville has 45k foot echo tops with some of the loudest thunder I've heard in a while

I see the watch is through 5am. Seems like they're fairly confident in an evolution like the 3kNAM has of the Ohio MCS making it over the mountains and re-strengthening after midnight.

I swear the dog-leg turn in the Potomac causes things to spin up down there more than normal. Anyone know if this has ever been looked into?

Heavy rain and lots of CG lightning with this complex that's been sitting over Albemarle the last hour. Starting to get nervous with that line to my north really solidifying and picking up speed..

WOW @ the last few scans. Radar lighting up across central VA/southern MD

Epic writeup. I knew a lot of this but seeing it so well laid out is nice. Saving to share with others!

I'll never forget that week. It was gnarly being outside. I was working at a summer sailing camp on the Potomac and we were gathering kids up and spraying them down (and ourselves) with the boat washing hoses to keep cool.

Radar looking really bad over 64 right now. Hook echo now clearly visible. Lots of rotation..

That large cell WSW of Richmond has been going since 4:45pm when it was coming off the Blue Ridge West of Charlottesville. Impressive echo tops, over 50k ft now. I got to watch it march into the Piedmont from the reservoir.

The section of the large line to the south that came through downtown Charlottesville was legit. Didn't see any hail but winds were easily gusting to 60+, rain going sideways, stormwater infrastructure quickly overloaded. Looks like CHO didn't get hit as hard based on the 5-min obs. Best storm of the year so far.

some sort of triple point visible on radar? What's going on SE of CHO? There's pretty clearly some kind of warm boundary stretching across VA. Made a drawing to show what I'm talking about.
