2026 Mid-Atlantic Severe Storm General Discussion

[midatlanticweather]

Cell north of Culpepper looks interesting.

I had a high of 82 today and was cloudy 95% of the time. Radar activity is weakening as it approaches western Loudoun. Looks like anything severe will be south and east of me. Not sure why the STW extended so far northwest.

It's juiced in the column for sure.  K-index as high as 40 in  w-cntrl VA.  That is about as high as it gets these parts.

whoa that cell near Manassas sure got itself together in a hurry... could be heading for DC?

Looks like a supercell and it is splitting now.

Downburst evident on the terminal radars.

In that cell between Culpepper and Warrenton, getting some legit straight line wind

It’s combined with the cell that popped up over 66 (I was driving west to get the culpeper cell) and it was nasty. Some of the heaviest rainfall you can get. The gust front is hitting me from the cell complex. I’m at the Herndon metro garage if anyone is interested in where my reports are from. They have a 6 story roof.

Has to be some hail in there too, some 68dbz pixels showing up

[SolidIcewx]

I hear constant rumbling from that storm to my NW here in south Alexandria

[SnowenOutThere]

Looks like the hooks reformed over GMU. Saw two bolts from the blue hit right over there 

[SnowenOutThere]

No visible rotation from my vantage point. Massive downdraft/microburst visible though.

Hmm, might get interesting soon on the Upper Eastern Shore.

A decent wind threat might be developing for areas south of I-66 and Route 50 w/ that squall line in VA.

At least to myself the velocity scans look rather unimpressive.

Rotation near Landover?
