    Completely unrelated to any thoughts about tonight/tomorrow... today marks nine years since the last time the immediate area was under a MOD risk of severe weather from the SPC.

    Yeap. I remember the June 3, 2020 derecho to our north producing hurricane-force wind gusts despite only weak to modest CAPE available and early time of day owing to the MCSs cold pool/ rear-inflow jet. Granted there were a couple hours of solar heating before the storms got to New Jersey where the most extreme damage occurred. But it was still solidly before peak heating with relatively modest LLLRs. Not that I expect that here, of course. Just pointing that out.

    Day 2 SLGT 2/15/15 Exerpt for MidAtl... ... At this time, one area of potentially greater storm coverage -- and thus severe potential, given the favorably strong wind field forecast atop the region -- will be along and east of the higher terrain of the central Appalachians. Storms should develop by early afternoon, and spread east-southeastward with time. Organized/rotating updrafts should evolve, given the available shear, with these stronger storms capable of producing large hail and damaging winds. Risk may continue well into the evening across portions of the area, as one of the more pronounced disturbances aloft shifts southeastward out of the Midwest and across the mountains during the evening/overnight.

    Just for laughs. Lol NAM. Sounding from the 6z NAM for Warrenton at 2pm Tuesday. Just a small hunch but I feel like the NAM may be overdoing CAPE here just a little bit.

    Yeah. Some CAMs such as the 18z HRRR is starting to hint at moderate instability and deep-layer shear in place by Sunday afternoon. Would be nice to get some action in these parts on Sunday before our early/mid week derechos.

    Sunday has actually had one of my eyes for the past 36-48 hours. Not for anything too major but some models have been showing fairly decent deep-layer shear for the day. It's just the CAPE that looks rather modest for anything too significant att.

    The storms outran the cold front to an extent. The wind shift and following lower dewpts seem to be located near I-81 atm.

    I really hope we get a pattern similar to what's being advertised by the GFS. Obvious uber-long range caveat aside, that would easily be a MOD risk worthy day from the MidAtl up into the Northeast verbatim.

    Central US ridges and NW flow over the Mid-Atlantic in June = a happy weenie A happy SEVERE weenie people! Calm down.

    BTW, with that watch the probs were: TOR: 20/5 WIND: 80/40 HAIL: 70/30 And just in case you're curious the first 20080604 watch had the same wind and hail probs but with 40/20 tornado probs.

    This is actually the site that wasn't working for me. But now it finally started loading. But still, thank you.

    Where did you retrieve this?... As I cannot seem to retrieve it from SPCs Severe Watches archive ATM.

    A wxdude64TM June morning.

    I'll definitely become a little more intrigued for the Wed/Thurs shortwave if timing can change a bit. It's probably easier to root for a slightly faster system (late Wed) rather than a slower system (Thurs) as of now as slowing it down by 18 hours may be a bit of a tall order compared to speeding it up by 6 hours. Either trend would maximize daytime heating as you probably know.

    How strong were the winds with that storm IYBY?
  17. George BM
    With 90/68 at IAD as of 12:28pm this is officially a heatwave for the location. (Third day at 90+F)

    Weenifying Thursday! Forecast Discussion Thursday, June 2, 2022 2:50PM EDT Temps have continued into the lower/mid 90s with dewpts into the lower/mid 70s. This combined with moderately steep MLLRs (6.5-7.5C/km) is yielding MLCAPE of 2500-4000J/kg. Swift flow between 600-400mb of 40-50kts will lead to effective bulk-shear of similar magnitudes leading to a mix of supercells and bowing line segments. With at least moderate low-level shear in place (ESRH 100-150m2/s2) a tornado or two cannot be ruled out, especially with any LEWPS that may develop. Otherwise, with large DCAPE in place (1000-1500J/kg), swaths of widespread damaging winds w/ a few significant gusts potentially up to 80mph will be commonplace, particularly with any bowing segments. Large to possibly very large hail will be a threat, particularly with any supercells that form. Tornado: 5% Wind: 45%(hatched) Hail: 15% Severe Thunderstorm Watch in effect for Northern/central VA, most of MD, Delaware, southern PA, southern NJ and the District of Columbia until 10PM EDT Thursday, June 2, 2022. Hazards: Widespread damaging winds w/ a few significant gusts to 80 mph likely. Scattered large hail likely w/ isolated very large hail to 2” diameter possible. A tornado or two possible. Watch Probs: TOR: 20%/10% WIND: 90%/70% HAIL: 60%/40% "Forecaster": George BM

    A triple H start. ETA: Happy Meteorological (Climatological) summer.

    IAD at 94/66 as of 3:28pm tying the daily record set in 2011.

    Aaaaaaand we're back! DCA: 108F IAD: 109F BWI: 110F RIC: 110F

    Now -3.
  24. George BM
    For Thursday.

    I don't remember there ever being WEAs for STWarnings before last year. I believe last year was when WEAs for STWs started for 2.75"+ hail and 80+ mph winds.
