Edit: Now tornado warned, but seems to have fallen apart now. Seems to be a recurring theme today. That area doesn’t need more damage. I called my mom, who was already downstairs in her safe space as she’s in that warning area 1 Link to comment Share on other sites More sharing options...

And then the area of rotation went right over us! You have any damage? I don't see any from the windows but the power was flickering a ton. I wonder how the Waugh Chapel Substation fared.

NorthArlington101 Posted 1 hour ago Share Posted 1 hour ago There was some pretty cool motion with the scud as the southern part of the cell that's now in Fairfax County moved through Loudoun Scud was rotating overhead.

Valid 282227Z - 282330Z The severe weather threat for Tornado Watch 529 continues. SUMMARY...A locally higher tornado threat may materialize in the next 1-2 hours. DISCUSSION...Multiple supercells have matured ahead of an approaching MCS. These supercells are intensifying within a very moist low-level environment, where 2000+ J/kg MLCAPE is present, and where the DOX VAD shows a modestly sized/curved low-level hodograph and over 200 m2/s2 0-3 km SRH. In addition to showing a modest increase in low-level rotation within the supercells, the absorption of these supercells into the MCS may promote conditionally favorable storm interactions which may briefly heighten the tornado threat. The best chance for a tornado will likely be within the next 2 hours. ..Squitieri.. 07/28/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...PHI...AKQ...LWX...

Yeah I just saw that on PulsePoint! Power outage counts from BGE are surprisingly tame given that wind.
