MESOSCALE DISCUSSION 0754
NWS STORM PREDICTION CENTER NORMAN OK
0852 PM CDT THU MAY 26 2016
AREAS AFFECTED...SOUTH KS...WEST OK
CONCERNING...TORNADO WATCH 214...216...
VALID 270152Z - 270245Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 214...216...CONTINUES.
SUMMARY...WITH WW/S 214 AND 216 SCHEDULED TO EXPIRE AT 03Z...SPC
WILL COORDINATE WITH AFFECTED WFOS REGARDING WATCH REPLACEMENT
AND/OR LOCAL TEMPORAL EXTENSION.
DISCUSSION...NUMEROUS STRONG TO SEVERE STORMS ARE ONGOING FROM
CENTRAL KS TO THE RED RIVER AREA OF SOUTHWEST OK/NORTHWEST TX.
FARTHER EAST...A WEST-EAST/ORIENTED QLCS PERSISTS ALONG/NORTH OF
LARGE-SCALE CONVECTIVE OUTFLOW ACROSS EAST-CENTRAL KS TO CENTRAL MO.
A PLUME OF 65-69 DEG F SURFACE DEW POINTS IS PRESENT WITHIN A
CONFINED CORRIDOR OF WEST OK ARCING INTO SOUTH KS. MODIFIED 00Z
OUN/LMN RAOBS SUGGEST AMPLE MLCIN EXISTS EAST OF THIS MOISTURE PLUME
ALONG THE I-35 CORRIDOR IN OK. THUS...OVERALL SPATIAL EXTENT OF THE
SEVERE RISK SHOULD HOLD ACROSS AREAS ALREADY UNDER A WATCH FROM WEST
OK AND SOUTH-CENTRAL KS. PRESENCE OF A 40-45 KT LOW-LEVEL JET WILL
BE SUPPORTIVE OF ALL HAZARDS NEAR-TERM /ESPECIALLY WITH STORMS THAT
CAN EVOLVE ALONG THE OUTFLOW BOUNDARY IN SOUTH-CENTRAL KS/.
CONGLOMERATION OF COLD POOLS AND UPSCALE GROWTH INTO AN MCS SHOULD
RESULT IN THE PREDOMINANT THREAT BEING STRONG TO SEVERE WIND GUSTS
TOWARDS MIDNIGHT. THIS WOULD APPEAR MOST LIKELY ACROSS SOUTH KS INTO
PERHAPS FAR NORTH OK.
