I saw your tweet. Do they also look good up near DC in addition to SEVA?

They aren't as intense in the DC region because the low-level jet will be to our south, but they're still alright. I'd definitely be more concerned with the post-frontal winds up this way.

my god what a disconcerting thread title...maybe add plague of locusts too?

wind maybe, but seems too soon for severe and fire

lol

Severe's a possibility to the south no doubt.

Last year's big brush fire event was on Feb. 19th... I think temps were in the 50s behind the front, with dewpoints in the low tens/single digits!

EDIT: Found the sounding from IAD that morning...

Had the mix layer labeled to show that gusts up to 65 knots were possible that day.

Fires can happen anytime it is dry and windy.

im pretty sure this and after leaf drop are our "fire seasons" if we have them. once it greens up not as much a concern

Wind gusts won't be much slower even if we don't get Tstorms. Temps spike to 74f on the Nam tomorrow. It's almost like a Colorado Chinook event. W boulder gusted to 104mph this year with no precip. I was in Pitt Hurricane Ike and we gusted to 75 with partly cloudy skies. So I'm not worried about tstorms tomorrow, they will not increase the windspeed much.

Is this activity from the warm-front or something else?

Yep, from the warm front, those showers are tapping the moist air coming out of NC. Speed shear above and a vort lobe to the NW is also helping the cells get going despite the lousy temp profile in the surrounding environment.
