AREAS AFFECTED...PORTIONS OF N-CNTRL OK INTO CNTRL/ERN KS
CONCERNING...TORNADO WATCH 102...
VALID 242250Z - 242345Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 102 CONTINUES.
SUMMARY...LARGE HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES WILL
CONTINUE TO BE POSSIBLE ACROSS MAINLY NORTHERN PORTIONS OF WW 102.
PORTIONS OF THE TORNADO WATCH IN S-CNTRL KS AND N-CNTRL OK MAY BE
CANCELLED EARLY IF CURRENT TRENDS CONTINUE.
DISCUSSION...ONGOING SUPERCELL OVER OTTAWA/SALINE COUNTIES IN KS
WILL CONTINUE NEWD OVER THE NEXT HOUR...POSING A THREAT FOR LARGE
HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES. LATEST RAP
MESOANALYSIS AND VWPS FROM KTOP/KICT SUGGEST THE LOW-LEVEL
ENVIRONMENT REMAINS FAVORABLE FOR TORNADIC DEVELOPMENT IN THE SHORT
TERM ACROSS PARTS OF CNTRL/ERN KS AS A LOW-LEVEL JET PRESENT OVER
MUCH OF THE MCD AREA STRENGTHENS WITH TIME THROUGH THE EARLY
EVENING.
FURTHER S ACROSS S-CNTRL KS INTO N-CNTRL OK...VISIBLE SATELLITE
IMAGERY SHOWS A LACK OF RECENT CUMULUS DEVELOPMENT ALONG THE
DRYLINE...AND AGITATED CUMULUS THAT WAS PRESENT EARLIER HAS
DISSIPATED. THE POTENTIAL FOR ADDITIONAL DEVELOPMENT ACROSS THIS
REGION IS BECOMING LESS LIKELY THIS EVENING AS LARGE-SCALE FORCING
FOR ASCENT WITH THE MID-LEVEL SHORTWAVE TROUGH OVER THE NRN/CNTRL
PLAINS BECOMES INCREASINGLY REMOVED FROM THIS AREA. IF CURRENT
TRENDS CONTINUE...PORTIONS OF THE TORNADO WATCH ACROSS S-CNTRL KS
INTO N-CNTRL OK MAY BE ABLE TO BE CANCELLED EARLY.
