  1. I'm actually mildly surprised that they put us in a MRGL for Day 3 as I personally don't see any glaringly obvious signs of models decisively backing off on Mondays potential yet (still better than usual MLLRs leading to sufficient CAPE w/ at least modest deep-layer shear). We'll see what transpires with CAMs and future SPC outlooks.
  2. I know my extreme naivety is showing here but what's this from?
  3. Summer! At 10:57am edt the sun hit its furthest point north of the equator (23.4 degrees N of equ.) directly above the earth's surface. It's on it's way back south now.
  4. Yeah that Monday/Tuesday timeframe has one of my eyes.
  5. Yeah. I'm not sure. My NOAA weather radio went off saying there was a watch for local counties (Arlington, Fairfax, etc... *shrugs*)
  6. Severe Thunderstorm Watch coming out for parts of our area?
  7. Guess what four letter word that starts with an 'H' (or 5 letter word that starts w/ an 'S') is coming back to play with us from late today through the next few days? Were you all starting to miss it?
  8. Off the top of my head I believe there was one last year on May 12th in the Plains.
  9. 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?!
  10. First sunset in a long time that's had no discernable haze in the sky. Nice deeper blue skies as well.
  11. 73/70 at IAD. IADs first 70F+ dewpoint of the year.
  12. Oh GFS. If only you didn't occasionally suffer from severe CFb (convective feedback).
  13. I wonder when the last time a Code Purple for air quality was issued for DC.
  14. 313 this hour! Into 'Hazardous' Level 6/6. We made it!
  15. Herndon AQI now up to 254. ETA: 276!
  16. Eyes are now slightly irritated. Impressive!
  17. AQI at Herndon is at 235 this hour. Let's go for 300+!
  18. 1 1/2 mile visibility at IAD.
  19. Up to 204 AQI here in Herndon, VA. Event of the year thus far.
