Classic intense WNW flow mid-June severe potential today. Moderate risk for wind issued by SPC. "A series of mid/upper shortwave impulses are expected to shift east across the Lower MS Valley and Southeast today in strong west/southwesterly mid/upper flow. Consistency among various forecast guidance shows at least 40-50 kt west/southwest flow between 850-700 mb with 60+ kt at 500 mb. A plume of very steep lapse rates will overspread the region, and 500 mb temperatures around -10 to -11 C will be common. Forecast soundings indicate midlevel lapse rates around 8-8.5 C/km over the region..." "...strong destabilization with MLCAPE values exceeding 3000 J/kg..." "...Locations may see a mix of supercells and intense bowing segments during the day, with potential for a derecho developing..." The upper Midwest can sure be interesting this time of year wi- one sec... Wait this is for the deep-south?!

Happy Ten Year Anniversary, weenies!

First sunset in a long time that's had no discernable haze in the sky. Nice deeper blue skies as well.

73/70 at IAD. IADs first 70F+ dewpoint of the year.

Oh GFS. If only you didn't occasionally suffer from severe CFb (convective feedback).

I wonder when the last time a Code Purple for air quality was issued for DC.

313 this hour! Into 'Hazardous' Level 6/6. We made it!

Herndon AQI now up to 254. ETA: 276!

Eyes are now slightly irritated. Impressive!

AQI at Herndon is at 235 this hour. Let's go for 300+!

1 1/2 mile visibility at IAD.

Up to 204 AQI here in Herndon, VA. Event of the year thus far.

Smoke has been the highlight of peak severe season... so far.

BTW... 2 1/2 mile visibility currently at IAD. 64/49

How does this morning compare to 2002 to those you you who remember?

Perhaps by the end of the week or this weekend locally.

Okay, this is some of the thickest smoke aloft that I've seen here thus far. The sun is still relatively dark and deep orange/pink two hours after sunrise.

Dark and strange...

The smoky haze will make its return later today and likely be around through at least tomorrow.

I believe this may be the first MRGL+ from SPC for parts of the area since April IINM?

Surprisingly IAD is still at 90F atm.

I just realized that the record at IAD for today is 91F tied in 2009. So IAD has broken the daily record by 2F thus far.

IAD up to 93F so far.
