Disc Posted April 28, 2011 Share Posted April 28, 2011 NOAA radio just keeps buzzing off tornado warnings here in Roanoke. Looks like we're in for it. Link to comment Share on other sites More sharing options...
yoda Posted April 28, 2011 Share Posted April 28, 2011 Just wow I think thats what will be headed our way in 2-4 hours Some of them also have golfball sized hail and destructive winds Link to comment Share on other sites More sharing options...
snowfan Posted April 28, 2011 Share Posted April 28, 2011 I think thats what will be headed our way in 2-4 hours I agree. Given what's in place right now, I think the areas east of the mountains are just waiting to explode. What we had in VA tonight was an appetizer. It could be quite rough pre-dawn into the early stages of rush hour tomorrow morning. Link to comment Share on other sites More sharing options...
Kmlwx Posted April 28, 2011 Share Posted April 28, 2011 I think thats what will be headed our way in 2-4 hours IF it maintains. That is the question right now. Remember, parameters have failed us before lol. Link to comment Share on other sites More sharing options...

BethesdaWX Posted April 28, 2011 Share Posted April 28, 2011 Some really nice CTC lightnings/spider lightning (whatever its called), 2nd best lightning event of the yr so far, runner up to the Lightning event 3 weekends ago. Looking out, it reflects on the potomac river, never realized it was happening until I left the PC. Link to comment Share on other sites More sharing options...

Kmlwx Posted April 28, 2011 Share Posted April 28, 2011 DP is 70 per NBC 4 just said... yuck The ingredients seem to be present. I also know that low LCL's improve tornado chances - but I don't know how to read those lol Link to comment Share on other sites More sharing options...

CranberryWX Posted April 28, 2011 Share Posted April 28, 2011 Tornado signature now just south of Beckley. A lot of this tornadic stuff seems to be in the line just west of the mountains...if it makes it over it could be trouble. Link to comment Share on other sites More sharing options...

A lot of this tornadic stuff seems to be in the line just west of the mountains...if it makes it over it could be trouble. It would certainly be continuing on into a juicy soupy airmass. Are any of you folks staying up? Or setting the weather radios up to wake you up if there's anything interesting? Link to comment Share on other sites More sharing options...

adelphi_sky Posted April 28, 2011 Share Posted April 28, 2011 I'm convinced there's a secret government science experiment where all violent storms dissipate over central D.C. Link to comment Share on other sites More sharing options...
VAwxman Posted April 28, 2011 Share Posted April 28, 2011 Just wow That's insane. At some point in next few hours the forcing should become more linear and lessen tornado risk some (exception being spinups in some lines of course), but the tornado threat is still there here in the near term.

Given what you said, woudl you think there could be a sizeable damaging wind threat to come for this area later on? Link to comment Share on other sites More sharing options...
VAwxman Posted April 28, 2011 Share Posted April 28, 2011 Given what you said, woudl you think there could be a sizeable damaging wind threat to come for this area later on? Very well could be. The juice is certainly there along with strengthening low level jet that could be brought down by downdrafts. Link to comment Share on other sites More sharing options...
CranberryWX Posted April 28, 2011 Share Posted April 28, 2011 Yeah i am waiting to see if this makes the jump, it could be a very dangerous night if it does The trajectory seems to be right at Trix and WVClimo's area in the next hour or so.

Thanks for the answer. Definitely bears watching I guess - unless the DC corn fumes knock it all down to showers. Are we talking max of 60mph or more damaging than that?
