MESOSCALE DISCUSSION 0749
NWS STORM PREDICTION CENTER NORMAN OK
0555 PM CDT THU MAY 26 2016

AREAS AFFECTED...SOUTH KS

CONCERNING...TORNADO WATCH 214...

VALID 262255Z - 270030Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 214 CONTINUES.

SUMMARY...PRIMARY SEVERE THREAT SHOULD REMAIN IN THE FORM OF LARGE
HAIL...BUT THE RISK FOR A TORNADIC STORM OR TWO MAY INCREASE
ESPECIALLY OVER PARTS OF SOUTH-CENTRAL KS.

DISCUSSION...SEVERAL SUPERCELLS WITH A MIXED CLUSTER/DISCRETE MODE
ARE ONGOING FROM SOUTHWEST TO EAST-CENTRAL KS...GENERALLY NORTH OF A
LARGE-SCALE OUTFLOW BOUNDARY. THERMAL GRADIENT ACROSS THE BOUNDARY
REMAINS STRONG AND STRENGTHENING LOW-LEVEL WAA SHOULD FOSTER
INCREASING STORM CLUSTERS THROUGH MID-EVENING. SURFACE DEW POINTS
HAVE GENERALLY MIXED INTO THE UPPER 50S TO MIDDLE 60S OVER NORTHWEST
OK...SUGGESTIVE OF MAINLY A HAIL/WIND AND BRIEF TORNADO THREAT NEAR
THE DRYLINE/OUTFLOW INTERSECTION. FARTHER EAST...LOWER 70S SURFACE
DEW POINTS PERSIST OVER SOUTH-CENTRAL/SOUTHEAST KS. AS THE LOW-LEVEL
JET INTENSIFIES...THE RISK FOR A COUPLE TORNADIC SUPERCELLS MAY
INCREASE WITHIN THE EASTERN PORTION OF WW 214.
