MESOSCALE DISCUSSION 0938

NWS STORM PREDICTION CENTER NORMAN OK

0643 PM CDT TUE MAY 24 2011

AREAS AFFECTED...CNTRL AND ERN OK THROUGH N-CNTRL TX

CONCERNING...TORNADO WATCH 356...

VALID 242343Z - 250045Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 356 CONTINUES.

THREAT FOR STRONG TORNADOES...VERY LARGE HAIL AND DAMAGING WIND IS

EXPECTED TO PERSIST FROM CNTRL THROUGH ERN OK INTO N-CNTRL TX THE

NEXT FEW HOURS.

NUMEROUS STORMS INCLUDING A FEW SUPERCELLS CONTINUE FROM N-CNTRL TX

THROUGH CNTRL AND E-CNTRL OK. MANY STORMS IN CNTRL OK HAVE BECOME

TEMPORARILY LESS ORGANIZED DUE TO DESTRUCTIVE INTERFERENCE

ASSOCIATED WITH CELL MERGERS AND OUTFLOW INTERACTIONS. HOWEVER...THE

ENVIRONMENT REMAINS SUPPORTIVE OF TORNADOES AND VERY LARGE HAIL WITH

LARGE 0-1 KM HODOGRAPHS AND STRONG INSTABILITY...AND SOME STORMS

WILL LIKELY REORGANIZE DURING THE EVENING. FARTHER SOUTH STORMS

REMAIN MORE DISCRETE ACROSS N-CNTRL TX AND WILL ALSO CONTINUE TO

POSE A THREAT FOR VERY LARGE HAIL AND TORNADOES.

Things could change, but it would have to change quickly to get the type of radar signatures we had between 21Z and 22Z.

Yeah, i'm not sure what the deal is with Sups going linear and then back to discrete again. Pretty sure once they go linear, because of the backing wind field, they normally don't go back discrete. Anyone with more knowledge than me, please chime in.

i think it's more that you still retain some supercell structure within the line, and increasing llj might help them spin harder again. if you look at vis sat you can see a few dots up the line with overshooting tops indicative of pretty powerful storms embedded still.

The storms that hit here in NC on Apr 16th went from a mostly linear line to a line of several discrete cells once the LLJ caught up to it.
