tornadotony Posted May 30, 2011 Share Posted May 30, 2011 This is screaming bust already, the few cells that are out there are joining up since the shear is basically unidirectional at this point. Yeah but that wouldn't at all be screaming bust... Link to comment Share on other sites More sharing options...
cyclone77 Posted May 30, 2011 Share Posted May 30, 2011 Some of the weaker updrafts may be getting knocked over by the strong mid-level winds. With instability still building the updrafts should continue to become more dominating. Link to comment Share on other sites More sharing options...
turtlehurricane Posted May 30, 2011 Share Posted May 30, 2011 Yeah but that wouldn't at all be screaming bust... Just talking from a discrete supercell standpoint. I'm sure this is gonna be a wicked convective complex, with embedded tornadoes. Already seeing nice spin-ups on the leading edge of the storm complex.

Chicago Storm Posted May 30, 2011 Share Posted May 30, 2011 This is one of those days when the SPC mesoanalysis says zero (or less than 25) CINH, but there's got to be something stopping parcels from becoming huge storms in the tornado watch box. 700mb temps sill running from 10-15C across the watch area.

cyclone77 Posted May 30, 2011 Share Posted May 30, 2011 The two cells southwest of Brewster don't look too bad to me. I know I wouldn't mind being there right now lol. Looks like they're starting to turn ever so slightly to the right too. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 30, 2011 Share Posted May 30, 2011 The cells in Nebraska are on the western edge of the higher surface instability as well. As they dig in and hook more right they should move into better instability. Link to comment Share on other sites More sharing options...

brettjrob Posted May 30, 2011 Share Posted May 30, 2011 What a crapfest... I had a sinking feeling as soon as those storms fired at 3pm in 88/64 type readings. Should've just started the drive back to OK right then, might've been able to make it without needing a motel. Just left the tornado-warned storm currently heading out of Rock Co. into Holt Co. -- it felt like it was about 60 degrees in its inflow region.

L.B. LaForce Posted May 30, 2011 Share Posted May 30, 2011 Just SSW of Fargo, ND looks prime, but man those H7 temps are ugly sitting at 13C. Looks like they are trying to fire on vis sat though. Link to comment Share on other sites More sharing options...
OHweather Posted May 30, 2011 Share Posted May 30, 2011 Just SSW of Fargo, ND looks prime, but man those H7 temps are ugly sitting at 13C. Looks like they are trying to fire on vis sat though. I'd guess there will be initiation up there within an hour or so. 700mb temps are certainly cooling from the SW to NE as the upper level jet streak moves in and heights fall. Definitely some convergence for things to fire once the cap weakens a little more. Link to comment Share on other sites More sharing options...
Jim Marusak Posted May 30, 2011 Share Posted May 30, 2011 just took a look at the 21z ruc soundings and compared them to reality for KRWF and KMSP. the lid's theoretically blown in RWF (with the line of clouds from KMOX to KSDA) while MSP is close to blowing (clear as a bell outside here in st paul but clouds trying to go from MCW to PEX).
