Expand It's up around 900 or so. Was it that much higher on previous days? Regardless, that's enough today to still have downburst issues, especially given the high CAPE. 1 Link to comment Share on other sites More sharing options...

I watched a pretty good bolt hit the ground very close to me in Towson with a huge bang last round of storms and a few min later on Radarscope it showed the bolt inside the blue location circle on my iPhone - - amazingly accurate I might add as the bolt hit to the south a bit and it was almost pinpoint accuracy to my eye on RadarScope. Are there lightning antennas all over town and its triangulating? That can't be it you would need to blanket the entire country! Link to comment Share on other sites More sharing options...

Kmlwx Posted August 13, 2021 Author Share Posted August 13, 2021 The area near Darnestown to Potomac and vicinity looks similarly placed as the PG/East MoCo area did earlier in the week. Backbuilding could keep them in heavy rain for some time. Probably going to be some cases of high water or flooding out that way. Link to comment Share on other sites More sharing options...

Kmlwx Posted August 13, 2021 Author Share Posted August 13, 2021 Weather radio has now gone off 3 times back to back. Busy day for LWX it seems. Lots of distant thunder being heard here in Colesville now. TDWRs have some nice pockets of wind with the complex inching closer to the metro area.
