Ian Posted June 21, 2011 Share Posted June 21, 2011 SPC Meso suggests some good parameters... Supercell parameter of 4 in Loudoun Cty. Derecho composite of 4 3000-4000 SBCAPE and 2000-3000 MUCAPE on the 2100 ehi is decent.. even got a little sig tor values. at least sref seems to have verified in that respect. maybe too messy with other storms crowding it, especially the one just northeast.

yoda Posted June 21, 2011 Share Posted June 21, 2011 2200 SPC meso has a bit of a jump in left moving supercell... up to -4 where these developing storms (sups?) are... supercell composite of 4 across C MD/DC/ N VA now... LI's -6 to -9. The 1 sig hail parameter increased in size. Link to comment Share on other sites More sharing options...

Agree... but I do see that MCS maintenance just went up to 60 in VA... 3km EHI of 5 Also... there is some ML Lapse Rates of 7.0 C/KM working into the VA area as well Link to comment Share on other sites More sharing options...
WVclimo Posted June 21, 2011 Share Posted June 21, 2011 0.25" of rainfall. Peak wind gust of 4 mph. Still 80 degrees. Thunder all around, though the sun has come out for now. Watching the trailing cells. Link to comment Share on other sites More sharing options...

CranberryWX Posted June 21, 2011 Share Posted June 21, 2011 Slow mover put down 1/2" in 20 minutes...decent lightning and wind, no hail. Temp dropped from 92 to 67 in a few minutes. Link to comment Share on other sites More sharing options...
Mrs.J Posted June 21, 2011 Share Posted June 21, 2011 Can see the storm that is to my NW. And hearing thunder in the distance. By the looks of radar though it looks as if it will slide to the SW of me. Hoping not. Link to comment Share on other sites More sharing options...

Ian Posted June 21, 2011 Share Posted June 21, 2011 MRB cell decided to change course... was moving SE and now is moving S it's sort of turning right.. it's weakish as far as sups go but it has a few characteristics. or it's just the updraft redeveloping to the right and im imaging things.

WVclimo Posted June 21, 2011 Share Posted June 21, 2011 Pretty wild and unusual storm. After a 20-minute lull with some sun, I'm now getting 20 mph winds and some small hail. Sheets of rain and the temp just dropped 5 degrees, finally. Link to comment Share on other sites More sharing options...

Sheets of rain and the temp just dropped 5 degrees, finally. you got into both storms in your area it looks.. with the first you were mainly in downstream anvil rain but it was probably sucking in warmer air from the east much of the time. looks like the second would have gotten you with the downdraft etc. Link to comment Share on other sites More sharing options...

Ian Posted June 21, 2011 Share Posted June 21, 2011 Very cool. Thanks for the explanation, Ian. interesting little storms.. they all have (had?) pretty solid and continual updrafts. something's missing.. i guess the weak shear is a problem.

EasternUSWX Posted June 21, 2011 Share Posted June 21, 2011 Thundered here for 2 hrs. And that was it. Now they are all dying again. Stinks not like Cape isn't 2500+ and shear is still at least 30kts. Link to comment Share on other sites More sharing options...
Ian Posted June 21, 2011 Share Posted June 21, 2011 That's a lot of storms. Hopefully tomorrow looks like that just over us. problem with tomorrow is the low moves like 12 feet from now till then.. just enough to put us in an even less sheared environment. i think we'll have some action though.. perhaps some decent storms.

WVclimo Posted June 21, 2011 Share Posted June 21, 2011 0.22" from the second round. 0.47" total. More interesting is the tally I've been keeping since late February: Now up to 66 of the 120 days since then with measurable rain here. (55% of the days) Link to comment Share on other sites More sharing options...

TradeWinds Posted June 21, 2011 Share Posted June 21, 2011 Oh lovely... storms crapping out again coming out of Washington County. Yeah, what's up with the Frederick split recently. Seems everything dies out or splits north/south as it approaches. My water bill is going to be sky high! I guess that is the nature of isolated storms.

My water bill is going to be sky high! I guess that is the nature of isolated storms. Well we have been getting it overnight. Woke up yet once again to a soaking wet yard. We live in new construction and our yard is all clay with sod so it turns into a bog after a heavy rain that is how I knew it had rained. I just want a decent storm in the daylight. But I agree with you on the "Frederick split" lately. I have actually watched storms coming split to the East and West only to reconnect to the south, frustrating to say the least.
