MESOSCALE DISCUSSION 1065
NWS STORM PREDICTION CENTER NORMAN OK
0439 PM CDT MON JUN 27 2016
AREAS AFFECTED...E-CNTRL CO / WRN AND SWRN KS
CONCERNING...SEVERE THUNDERSTORM WATCH 302...
VALID 272139Z - 272315Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 302
CONTINUES.
SUMMARY...THE THREAT FOR ISOLATED SEVERE WILL PROBABLY DEVELOP SOUTH
OF THE EXISTING SEVERE THUNDERSTORM WATCH. HAIL/WIND WILL BE THE
THREATS WITH THIS ACTIVITY AND A NEW SEVERE THUNDERSTORM WATCH IS
LIKELY /80 PERCENT/ TO THE SOUTH OF SEVERE THUNDERSTORM WATCH 302.
DISCUSSION...RADAR MOSAIC SHOWS A LOOSELY ORGANIZED BAND OF STORMS
ON THE LEADING EDGE OF ARCING OUTFLOW LOCATED FROM 55 MI SSE GLD TO
45 MI SW ITR AND THEN NWD INTO NERN CO. SURFACE OBSERVATIONS SHOW
TEMPS SOUTH OF THE STORMS IN THE LOW-MID 90S AND DEWPOINTS RANGING
FROM THE LOWER 60S NEAR GCK TO THE LOWER 50S IN SERN CO. AS A
RESULT...SIZABLE TEMP/DEWPOINT DEPRESSIONS ARE LOCATED TO THE S OF
THE SWD-MOVING OUTFLOW BOUNDARY ALONG THE KS/CO BORDER.
OBJECTIVE ANALYSIS AND RAP MODEL DATA INDICATE W-CNTRL INTO SWRN KS
WILL REMAIN ON THE SRN PERIPHERY OF THE STRONGER DEEP-LAYER SHEAR
VECTORS LATE THIS AFTERNOON/EVENING. FURTHERMORE...THE ADEQUATELY
MOIST ENVIRONMENT COUPLED WITH STEEP LOW TO MID-LEVEL LAPSE RATES
WILL PROMOTE GUSTY OUTFLOW WINDS AND THE POTENTIAL FOR LARGE HAIL.
IF A SUPERCELL CAN BE MAINTAINED ACROSS W-CNTRL KS...THE THREAT FOR
VERY LARGE HAIL /2 INCHES OR GREATER IN DIAMETER/ WILL ACCOMPANY THE
STRONGEST ROTATING UPDRAFTS.
