Mid-Atlantic summer hottest temperature contest
George BM replied to PrinceFrederickWx's topic in Mid Atlantic
A temperature of 105F with a dewpoint temp of 85F will give you a @Subtropics heaven and @wxdude64 killing 140F heat index. -
FWIW (not much at this range) check out the "decent" squall line(s) on sim reflectivity through the entire region on the 0z wrf suite. Obviously far out at the end of their range though.

One little note. No mesoscale model has the current activity in Eastern Ohio about to move into southwest Pennsylvania. CAPE is modest but still... it might be able to trigger something in the area later even if the current convection dies out. Just a small note. #Notanexpertopinion

It's a very low-key threat and more likely than not won't happen this way but a few mesoscale models try to get some remnant storms into the region tomorrow afternoon before they redevelop into asoutheastward moving storm cluster or two. This, of course, would be the most extreme case though. Just low-key watching it and exactly where the WNW to ESE oriented front sets up.

I wonder if you'd find any kind of damage if you went to those locations? Might be very minimal but still. *shrugs*

I love how some areas west of I-95 that hadn't been under a Tornado Watch since February 24, 2016 have been under 3 Tornado Watches in 12 days.

Surprised that we aren't at least in some tornado risk atm. I would think that changes later though.

I'm wondering whether anything will try to pop up along the front northwest of I-95 looking at recent satellite trends. Not necessarily talking anything too big but perhaps at least some t-showers. #Notanexpertopinion

(August 26, 2003) (June 4, 2008) (June 29, 2012) all featured a good MCS for at least a good portion of the region... June 29, 2012 obviously being the best area-wide event (except for the Maryland/Pennsylvania line).
