Kmlwx Posted June 2 Author Share Posted June 2 TDCA is seeing some 50-55mph winds with the Montgomery cell still. Wind threat does seem to be a touch lower than before. CIMMS probsevere numbers a bit lower again as well - but could rise again. Link to comment Share on other sites More sharing options...

batmanbrad Posted June 2 Share Posted June 2 That earlier squiggly outflow boundary that was heading north from the earlier storms either has or is about to intersect that Montgomery cell. Link to comment Share on other sites More sharing options...
87storms Posted June 2 Share Posted June 2 not much in the way of storms firing past this first round. maybe the atmosphere got tired of raining. i am intrigued by the cell moving through boonsboro though. that would be a direct hit for mby.

Kmlwx Posted June 2 Author Share Posted June 2 Pea sized hail coming down in Colesville, MD! Torrential rain as well. Funny that the lead cell ended up delivering hail for me. The earlier dominant cell will go S of me it seems. Link to comment Share on other sites More sharing options...
yoda Posted June 2 Share Posted June 2 Actually quite impressive that the the storm was able to produce hail to ping pong ball size in Loudoun County with ML Lapse Rates so poor... wonder if it just took advantage of the instability and boundary?

midatlanticweather Posted June 2 Share Posted June 2 It was good in Purcellville at the start with some serious heavy rain too. Did not last too long but picked up 0.3 inches in about 10 minutes Link to comment Share on other sites More sharing options...

Juicy 90+ temps can work wonders if the right trigger goes through. We also had enough shear to get some updraft rotation like the earlier discussions. More organized version of the July-style pulse severe we get where a cell goes up but quickly collapses. 1 Link to comment Share on other sites More sharing options...

mattie g Posted June 2 Share Posted June 2 This untrained not spotter experienced heavy rain, no wind, and the occasional thunder. Mid-Atlantic severe at its middling best! 1 Link to comment Share on other sites More sharing options...
Kmlwx Posted June 2 Author Share Posted June 2 Decent CAPE and decent shear equaled this - even in the absence of good ML lapse rates. Also many of us got good sun today. It was a recipe for a good performance of severe weather. Number of LSRs is impressive. This will easily verify the watch and the overall risk area from SPC it looks like. Will be fun to see this show up in future years CIPS guidance. 1 Link to comment Share on other sites More sharing options...
