AREAS AFFECTED...PORTIONS OF WESTERN INTO CENTRAL KANSAS
CONCERNING...SEVERE THUNDERSTORM WATCH 358...359...
VALID 210129Z - 210300Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 358, 359
CONTINUES.
SUMMARY...SEVERE WIND GUSTS EXCEEDING 75 MPH WILL REMAIN A CONCERN
OVER THE NEXT FEW HOURS WITH A SOUTH-SOUTHEASTWARD PROGRESSING MCS.
DISCUSSION...A COLD-POOL-DRIVEN MCS CONTINUES TO PROPAGATE TO THE
EAST-SOUTHEAST ACROSS WESTERN KS, WITH A HISTORY OF 60-100 MPH WIND
GUSTS. THE DDC 00Z OBSERVED SOUNDING, WHICH IS WELL AHEAD OF THE
MCS, DEPICTS AN ELONGATED HODOGRAPH AND OVER 50 KTS OF EFFECTIVE
BULK SHEAR, WHICH SHOULD AID ONGOING STORMS TO SUSTAIN A BOWING MCS
STRUCTURE. HOWEVER, WHILE THE 00Z OBSERVED SOUNDING SHOWS 8.5+ C/KM
MID-LEVEL LAPSE RATES PRECEDING THE MCS, A RELATIVELY
NEUTRAL/SLIGHTLY STABLE 850-700 MB LAYER MAY EVENTUALLY ENCOURAGE A
WEAKENING TREND IN THE NEXT FEW HOURS GIVEN NOCTURNAL COOLING. THIS
TREND IS ALSO SUGGESTED BY THE LATEST HRRR DETERMINISTIC AND WOFS
ENSEMBLE RUNS. UNTIL THEN THOUGH, SEVERE GUSTS (A FEW POTENTIALLY
EXCEEDING 75 MPH) REMAIN POSSIBLE THROUGH AT LEAST 04Z.
