    Tuesday, August 4, 2026 11:38AM EDT Skies continue to clear from west to east following this morning’s rain and storms. Much of the region generally picked up between half an inch and an inch of rain. As we go through the afternoon temps will rise into the lower 90s w/ dewpoints getting into the mid/upper 70s leading to 3000-4000 J/kg MLCAPE beneath the 6.5-7 C/km MLLRs. As the unseasonably strong shortwave approaches from the west it will most likely bring with it a complex of thunderstorms congealing into a severe MCS. At the same time, a couple of supercells may develop over the region ahead of the main cluster and with near 60kts of EDWD and effective SRH in excess of 250m2/s2 these have the potential of producing strong to intense tornadoes. SPC has us under a 10% CIG1 tornado risk to account for this. We are also under a 60% CIG1 wind risk resulting in a level 4 out of 5 Moderate risk of severe weather. With the high CAPE, decent DCAPE (1000+ J/kg) and high Pwats around 2 inches, the MCS could bring widespread 65 to 80+ mph wind gusts across the region with even higher gusts in any embedded microbursts resulting in widespread and potentially long-lasting power outages along with major tree damage and some structural damage to boot. Stay tuned to the evolving weather situation and take all the necessary precautions.

    Just a lightning barrage with that eastern Loudoun county storm.

    Yeah only down to 81F on the day so far. If no rogue storm pops up later we could at least tie the all-time or have the first 80+ daily low there. (You, of course, know this. I just like talking sometimes. ) ETA: LOL! I should've read the post above before commenting. I was still on the last page.

    Temperatures were in the low/mid 80s for my pre-dawn run this morning. Way too warm. Was probably lot too far away from heat exhaustion at one point. Hydrate! IAD currently at 92/72.

    Yeah, big heat coming. We are now under an Extreme Heat Watch (formerly 'Excessive Heat Watch') for Thursday morning through at least Friday evening.

    Was on a morning run when that came over me. Nice sized drops w/ visibility down to about 1/3 mile. Hot non-A/C house feels nice now being soaked . Window is open w/ outside temps in the upper 60sF.

    Tornado Warning near Quantico and into Charles county, MD now.
  23. George BM
    A decent wind threat might be developing for areas south of I-66 and Route 50 w/ that squall line in VA.

    Mr. Blue Box coming out until 11pm EDT.

    It was neat seeing the wet microbursts along the leading edge of the storm. Probably some damage on your drive home.
