That statement pretty much sums up our climate lol. I guess I'll be watering the garden tonight. 

 

We have the best climate, however CFA is a major influence in the US....expands deep into the Midwest/Texas. What you're getting at is just unlucky variability.

Yeah it doesn't take much of a departure to top 90 during peak climo. It'll be interesting to see (for me at least) where the temps fall this summer. Summers and winters have done the opposite of what I thought they would since I moved here.

Well, we had three consecutive fire-pit summers from 2010-2012, and believe me when I say you're lucky you weren't living here. We had a day or two where heat indexes approached or exceeded 120 degrees in 2011. The heat was persistent, too. It stuck around for weeks on end, and any breaks were short lived.

Once we get back into a La Niña regime, I'm sure the furnace turn back on.

00z NAM still kinda likes the area around evening time fwiw when peeking at soundings

 

ETA: 00z 4km NAM really likes Monday evening on the radar forecast and so does the 00z NAM Radar Reflectivity at 48 and 51 hrs

 

00z GFS looks okay peeking at soundings for Sunday evening as well

That's pretty much average for mid/late July, actually. The average July high in DC since 1979 is 90.3, if I'm calculating it right. Even 94-95 degrees is kinda run of mill here during the dog days.

We've been spoiled beyond belief over the last 2 years.

FWIW, SPC mesoanalysis at 15z already has us around 2000 SBCAPE and 1000 MLCAPE

 

Hmmm... 16z has a small area of 2000 MLCAPE and 3000 SBCAPE right over/near KIAD with LI's around -5

 

ETA: Yes, i know shear sucks... i just want some good storms this evening

2500-3000 SBCAPE with 1500-2000 MLCAPE and LI's at -6 look nice at 17z... hope we can get some storms going in a few hours

Could someone explain this image a little better?  I think i get the concept of it, but i just want to be sure -- the higher number means a better chance for severe hail, yes?  The SPC disco of what the map means still has me a bit confused.
