That placefile for GR that EJ sent a few weeks ago (maybe longer?) is spectacular. Love how conservative it is. any chance you have a link to that? dm me if so, always looking to up my GR experience.

Can watch 4 different radars at once, which is kinda neat. Anyways, DC split looks real, though might be a couple thundershowers coming out from under the radar beam. Wouldn't mind a break today, anyway. 1 Link to comment Share on other sites More sharing options...

That kicker @Eskimo Joe - mentioned earlier today is definitely putting the work in thus far. We'll see what happens to the east...the HRRR kind of had a tendency to kill off storms as they approached the metros - but IMO it hasn't been great the past few days. Perhaps the pulsey nature is throwing guidance for a loop a bit with no organized trigger. I was thinking exactly the same thing just a few minutes ago.

We already see initiation. Seems like they'd hit maturity just as their getting inside the beltway. Link to comment Share on other sites More sharing options...

Tricky day to forecast, as the lack of shear keeps allowing the outflow to surge way out ahead of the storms, so we rely on re-development for the downstream threats.

MDphotog Posted August 11, 2021 Share Posted August 11, 2021 So, not sure if I can explain this well enough, but here goes. Is there such a thing as a super gust front or meso-gust front? I like to think I am pretty aware of a standard gust front signature on radar, but I just saw something interesting on College of DuPage's Satellite loop. If you click on the GOES-East Washington DC (Localized Sector) and set it to 96 frames. Up in Eastern Central PA around Pittsburg watch at frame 66 (18:11:17 UTC) to frame 88 (20:06:17 UTC). There is a very large bow arc that appears to shoot off a large cluster of storms and races south east. This is now triggering more storms out in the west. This seems much larger than a typical gust front, or at least that I can recall. Anyone chime in to what I was looking at? Thanks for any help.

Hearing that it was pretty bad as it passed through Bethesda. Didn’t see anything up on Montgomery County Fire Twitter yet, so hopefully nothing too serious. Well, beltway is fubur more than usual. That is not a shock though. It is so incredible how the atmosphere is ready to pop if the right trigger is applied. That line went from nothing to dangerous in maybe 15mins. This is one of those things that draws me to this “hobby”. Link to comment Share on other sites More sharing options...

The worst definitely missed me in Colesville just south. Pretty good string of storm days around the area. While not every locale has been hit daily - many are cashing in.

mattie g Posted August 11, 2021 Share Posted August 11, 2021 Just had some heavy rain for five minutes this evening in Burke, followed by stratiform stuff after the line went through. No complaints, though. Severe is interesting, but just getting some light rain for an hour or two works perfectly at this time of year. 1 Link to comment Share on other sites More sharing options...

AdamHLG Posted August 12, 2021 Share Posted August 12, 2021 A suspected lightning strike sparked a 2 alarm house fire in Frederick County resulting in a mayday on the fireground. Thoughts and prayers to the Frederick County FD and family of the fallen firefighter. It has been posted in fire department circles that this is a LODD. 4 Link to comment Share on other sites More sharing options...

WEATHER53 Posted August 12, 2021 Share Posted August 12, 2021 Was on Reichs Ford and just to south along 80 lost traffic lights and other electric out. Soon as headed down 270 the limb damage look liked about 60mph winds for a 1.5 mile stretch Link to comment Share on other sites More sharing options...
