    I saw a few mangled wet snowflakes and ice pellets mixed in w/ the rain att in Herndon.

    Bump.

    The sleet has gotten a bit heavier. 42/30 at IAD.
  4. George BM
    Sleet here in Herndon as well. The April traces continue!

    I wonder if some of us see some hail/gusty winds later with any convection/storms that manage to develop in the region. MLLRs will be fairly steep w/ 500mb temps of -20 to -22C. LLLRs look to be very steep as well. Weak instability (MLCAPE generally less than 500J/kg) owing to fairly low dews (45-50F) while a limiting factor may be slightly offset by the very steep LLLRs. Not expecting anything too crazy. Maybe some gusty winds and some hail like I mentioned.

    CAPE is very pleased about this.

    This is a nice site for one-min obs at IAD. http://iadasos.org/IAD/index.html

    Now IAD is at 85/58.

    IAD has hit 83F so far today.

    @SnowenOutThere Yeap. I know what you're about to post.

    Oh wow. Both of you chasing. That's a nice duo between you and your wife.

    Or some severe and upper 70s?...

    Got my April trace! Just had a light shower w/ big raindrops mixed in with graupel at 52F.
  15. George BM
    The bolt was a powerful 194kA positive CG. Lots of jumps, yelps and/or more personal "events" were probably had by peeps in the strike region... especially with no previous bolt to signify lightning in the area.

    Let the April traces commence!

    Moving deeper into spring. Happy Pollen Sufferers Awareness Month!
  19. George BM
    New month starting. Baseball. NHL Playoffs w/ the Capitals? Booze consumption. Legit severe?
  20. George BM
    Some digital severe to enjoy from the 12z GFS today over Sterling, VA. Long range caveats (of course). But if nothing else it shows that we're reaching that TOY where our threats start becoming "CAPE-ier."
  21. George BM
    22... but I'm 25.

    June 13, 2013. A strong morning MCS stabilized the atmosphere a bit and we were downgraded to a SLGT by the 1630z update. Parts of the region particularly from northern/central Loudoun county eastwards into Montgomery and Howard counties and perhaps beyond got decent storms that afternoon w/ 40-50 kt effective bulk shear and up to 1,000J/kg MLCAPE.
  23. George BM
    No you don't.

    A lot of the lightning bolts from the I-95 storms last night were strong w/ peak currents between 50-100 kiloamps (some were over 100kA). Generally the vast majority of bolts produce peak currents of roughly 20-30kA give or take.
  25. George BM
    With cold temperature profiles and steep surface to 600mb lapse rates some of the most intense showers on Saturday could contain some graupel despite surface temps reaching 50+F. A rogue lightning discharge or two may even occur should any convection get deep enough.
