AREAS AFFECTED...PORTIONS OF SWRN KS AND NWRN OK

CONCERNING...SEVERE THUNDERSTORM WATCH 253...

VALID 140202Z - 140330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 253
CONTINUES.

SUMMARY...AN MCS CROSSING PARTS OF SWRN KS...THE ERN OK
PANHANDLE...AND THE NERN TX PANHANDLE WILL MOVE INTO/ACROSS WRN
SECTIONS OF THE BODY OF OKLAHOMA IN THE NEXT FEW HOURS. A RISK FOR
SVR WIND GUSTS WILL CONTINUE TO ACCOMPANY THIS ACTIVITY.

DISCUSSION...A MEASURED SVR WIND GUST OF 52 KT WAS REPORTED WITH THE
FORWARD-PROPAGATING MCS AS IT CROSSED LIBERAL KANSAS EARLIER. AS THE
LEADING CONVECTIVE LINE PROGRESSES EWD...IT WILL CONTINUE TO
ENCOUNTER WARM/MOIST INFLOW...WITH A LOWEST-100-MB MEAN MIXING RATIO
AROUND 15.5 G/KG SAMPLED BY THE 00Z OUN RAOB. VNX VWP DATA INDICATE
SLIGHTLY STRENGTHENING LOW-LEVEL SLYS IN THE LAST COUPLE OF
HOURS...THAT WILL LIKELY FACILITATE SOME SWD PROPAGATION OF THE MCS.
THIS SHOULD FOSTER NET MCS MOTION ON MORE OF A ESEWD/SEWD TRACK
ACROSS AS IT ENTERS THE BODY OF OKLAHOMA...WHERE GPS DATA INDICATES
IT WILL ENCOUNTER INCREASING PW. THIS SHOULD SUPPORT CONTINUED MCS
MAINTENANCE WITH A RISK FOR SVR WIND GUSTS CONTINUING. THE SVR RISK
WILL DIMINISH TO NIL BEHIND THE LINE OF TSTMS.
