MD update from SPC

MESOSCALE DISCUSSION 0565
NWS STORM PREDICTION CENTER NORMAN OK
0349 PM CDT SAT APR 25 2009

AREAS AFFECTED...EASTERN TX PANHANDLE...WESTERN OK AND SOUTH-CENTRAL
KS

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 252049Z - 252245Z

UPDATE TO EARLIER DISCUSSION.

RADAR/SATELLITE INDICATE THE STALLED FRONT HAS BEGUN A VERY SLOW
RETREAT NWD THROUGH THE TX PANHANDLE AND NORTHWEST OK WHILE THE
DRYLINE WAS MIXING EWD TO ARMSTRONG TO CROSBY COUNTIES IN TX.
TOWERING CU WAS BUBBLING AT THE INTERSECTION OF THE TWO OVER
SOUTHWEST GRAY COUNTY TX...IN THE FREE WARM SECTOR OVER WCENTRAL OK
AND NORTHEAST ALONG THE FRONT.

LARGER SCALE ASCENT WILL IMPROVE AFTER 22Z IN WAKE OF THE EARLIER
DISTURBANCE MOVING INTO EASTERN KS PER WATER VAPOR IMAGERY. THIS
WILL ACT TO DEEPEN THE DRYLINE/FRONTAL CIRCULATION AND INITIATION
STILL LOOKS TO BE ACROSS THE EASTERN TX PANHANDLE...NORTHEAST ALONG
THE FRONT INTO WEST-CENTRAL/NORTHWEST OK IN AN HOUR OR TWO /ASIDE
FROM ACTIVITY DEVELOPING IN CNTRL/ERN KS/. MODIFYING THE 20Z NORMAN
SOUNDING FOR A 88/58 AIR PARCEL SUGGESTS VERY LITTLE CAP AND MLCAPES
OF OVER 2000 J/KG. CORRIDOR FROM JERICHO-TURKEY TX NORTHEAST ACROSS
ERICK...ELK CITY...CLINTON...WATONGA AND ENID NORTH TO JUST NW OF
THE FRONT WILL HAVE THE HIGHEST SEVERE PROBABILITIES THROUGH EARLY
EVENING.

REMAINDER OF THE BELOW DISCUSSION STILL VALID.

SOMEWHAT ANEMIC VERTICAL SHEAR PROFILES NOTED CURRENTLY SHOULD
IMPROVE BY INITIATION TIME AS STRONGER SOUTHWESTERLY MID-LEVEL WINDS
OVER THE SOUTHERN ROCKIES EDGE SOUTHEASTWARD. WIND PROFILES WILL
BECOME VERY CONDUCIVE FOR SUPERCELLS WITH GIANT HAIL GREATER THAN 2
INCHES IN DIAMETER. IN FACT...AS THE GREAT BASIN UPPER TROUGH
CONTINUES TOWARD THE SOUTHERN ROCKIES...SOUTHERLY BOUNDARY LAYER
FLOW IS EXPECTED TO INCREASE TO OVER 55 KTS DURING THE EVENING.
THIS WILL NOT ONLY MAINTAIN DISCRETE SUPERCELL STRUCTURES AS RICH
MOISTURE INFLOW CONTINUES...BUT ALSO BOOST 0-1KM STORM RELATIVE
HELICITY TO AT OR ABOVE 400 M2/S2. THIS WILL LIKELY YIELD
LONG-LIVED SUPERCELLS WITH POSSIBLE STRONG TORNADOES WHICH MAY LAST
WELL BEYOND SUNSET ACROSS WEST-CENTRAL/ NORTH-CENTRAL OK INTO
SOUTH-CENTRAL KS.

The cap over western oklahoma is very strong right now, everything is getting killed by the cap at the moment, but that should start weakening rapidly after 5pm and we'll probably have more widespread convection 5:30 or 6pm.
