MESOSCALE DISCUSSION 0824
NWS STORM PREDICTION CENTER NORMAN OK
0541 PM CDT MON MAY 27 2013
AREAS AFFECTED...WRN NEB...NERN CO...NWRN KS
CONCERNING...SEVERE THUNDERSTORM WATCH 228...
VALID 272241Z - 280015Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 228
CONTINUES.
SUMMARY...POTENTIAL FOR ISOLATED SEVERE HAIL/WIND AND EVEN A BRIEF
TORNADO CONTINUES ACROSS MOST OF THE WW.
DISCUSSION...PRIMARY SEVERE THREAT REMAINS WITH TSTM CLUSTERS OVER
THE NEB PANHANDLE AND FAR NERN CO. DOWNSTREAM SURFACE TEMPERATURES
CONTINUE TO WARM INTO THE MIDDLE TO UPPER 70S AS OF 22Z. THIS SHOULD
SUPPORT A CONTINUED SEVERE RISK AS ACTIVITY GRADUALLY EVOLVES EWD.
DEEP-LAYER SHEAR PROFILES ARE MARGINAL PER KLNX VWP DATA...AND WITH
THE EVENING LLJ INCREASE EXPECTED TO REMAIN FARTHER SE IN WW
231...SUSTAINABILITY OF SEVERE CONVECTION APPEARS QUESTIONABLE.
CONVECTION FARTHER S ALONG THE CO/KS BORDER SHOULD WEAKEN DURING THE
NEXT HOUR OR SO AS FOCUSED ASCENT SHIFTS E OF THE HIGH PLAINS. UNTIL
THEN...PRESENCE OF AN OUTFLOW BOUNDARY WILL SUPPORT A LOCALIZED
LANDSPOUT TORNADO RISK...WITH ISOLATED SEVERE HAIL/WIND ALSO
POSSIBLE.
