Eskimo Joe Posted September 8, 2023 Share Posted September 8, 2023 2nd round of ping pong ball sized hail at LWX WFO. 1 Link to comment Share on other sites More sharing options...
Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 This is insane for the long duration hail production and also the slow movement of these storms. Barely making any east progress towards my area. Link to comment Share on other sites More sharing options...
Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 Even the new stuff popping near Rockville and Rossmoor has mostly a northerly motion. Outflow from the NoVA storms getting ready to go over MBY. Link to comment Share on other sites More sharing options...

Keep hoping the outflow will start dragging stuff east more but it's not happening. That new development is going to be too far north to get me - might get clipped by rain I guess. Huge dead zone in the activity between the outflow and the stuff back in NoVA still. Interesting storm day... Link to comment Share on other sites More sharing options...
batmanbrad Posted September 8, 2023 Share Posted September 8, 2023 definitely looks like some boundaries are colliding in central MoCo. I'm here close to Laytonsville, skies just opened up and have some pretty solid wind gusts so far. Link to comment Share on other sites More sharing options...
Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 And now the cell near Haymarket seems to want to become a hail producer too...man...places running from Haymarket up to like Ashburn (including LWX) are getting absolutely demolished by this stuff. Would think at some point overturning will weaken the stuff.. Link to comment Share on other sites More sharing options...

09-10 analogy Posted September 8, 2023 Share Posted September 8, 2023 Outflowing thru the neighborhood now. Just like yesterday: big cells off to the N and W (actually they were close to MNOTW yesterday). What field (if any) on the SPC Hourly Meso Analysis would be best to approximate the location of outflow boundaries? Or is that just eyeballing radar? (And I don't have GR3 or whatever it's called; I just rely on LWX or some other free sites. Now if I lived in Huntsville ...) Link to comment Share on other sites More sharing options...

I guess you could discern some boundaries via surface temps since they generally have cooler air behind them. But honestly radar is probably best for that. And they are often such small scale features and overall short in duration that an hourly mesoscale analysis might not pick them up that well. But also CINH.

Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 And so far not a ton to speak of along the boundary collision area. Something tells me that what will happen is eventually that narrow corridor of repeating storms/hail is going to run out of gas and just sort of gust out and just be showers. Not saying game over for areas to the east yet...but there's not unlimited CAPE. And with the boundary clearing big chunks of the area - that'll drop temps and stabilize us potentially.

Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 a cell is popping up down near Bowling Green. Would be funny if that came up and got DC/Eastern MoCo. Link to comment Share on other sites More sharing options...

Kmlwx Posted September 8, 2023 Author Share Posted September 8, 2023 Unrelated....but that radar interference seemingly keeps getting worse (or maybe it's just depending on where precip is located) but it really has hurt radar accuracy in that area right near/south of the VA/MD/DC border intersection. Results in that phantom return pattern over in southern Anne Arundel County as well. Link to comment Share on other sites More sharing options...
