MESOSCALE DISCUSSION 0672
NWS STORM PREDICTION CENTER NORMAN OK
0902 PM CDT SAT MAY 21 2016
AREAS AFFECTED...WEST AND NORTHWEST KS
CONCERNING...TORNADO WATCH 187...
VALID 220202Z - 220300Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 187 CONTINUES.
SUMMARY...THE GREATEST SEVERE-WEATHER THREAT IN THE SHORT TERM
/THROUGH 03Z/ IS GENERALLY CONFINED TO A SMALL PART OF WEST-CENTRAL
AND NORTHWEST KS /INCLUDING THE COUNTIES OF NORTHERN
WICHITA...LOGAN...EASTERN WALLACE...SOUTHEAST SHERMAN AND SOUTHWEST
THOMAS/.
DISCUSSION...TRENDS IN MOSAIC RADAR IMAGERY AND SURFACE ANALYSES
SUGGEST THE SOUTHERN EXTENT OF THE ONGOING CLUSTER OF STORMS IN
WEST-CENTRAL AND NORTHWEST KS IS ANCHORED ALONG A WARM FRONT...WHICH
EXTENDED FROM NORTHEAST CO THROUGH LOGAN COUNTY TO SEWARD/MEADE
COUNTIES KS. ALTHOUGH THE LOSS OF DAYTIME HEATING IS SUPPORTING AN
INCREASE IN SURFACE-BASED INHIBITION...FURTHER ENHANCED BY THE CAP
EVIDENT IN THE DDC 00Z SOUNDING...A 30-40 KT SSELY LOW-LEVEL JET IS
MAINTAINING AN INFLOW OF MODERATELY UNSTABLE AIR INTO THE STORM
CLUSTER. EFFECTIVE BULK SHEAR OF 35-40 KT WILL BE SUSTAINED
SUPPORTING A CONTINUATION OF STORM ORGANIZATION. IF STORM
INTENSITIES DO NOT WEAKEN PRIOR TO 03Z...THEN A PORTION OF WW 187
MAY NEED TO BE EXTENDED IN TIME BY THE LOCAL WFO.
MEANWHILE...AN INCREASE IN SURFACE-BASED INHIBITION WITH SOUTHWARD
EXTENT INTO SOUTHWEST KS AND NORTHWESTWARD ACROSS NORTHEAST CO WILL
LIMIT NEW THUNDERSTORM DEVELOPMENT.
