AREAS AFFECTED...CENTRAL KANSAS INTO SOUTH-CENTRAL NEBRASKA
CONCERNING...SEVERE THUNDERSTORM WATCH 253...
VALID 310029Z - 310230Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 253
CONTINUES.
SUMMARY...THE THREAT FOR SEVERE WIND AND HAIL CONTINUES ACROSS
PORTIONS OF CENTRAL KANSAS AND SOUTH-CENTRAL NEBRASKA, INCLUDING
BEHIND THE PRIMARY BAND OF THUNDERSTORMS WHERE NEW CONVECTION IS
DEVELOPING ALONG OUTFLOW BOUNDARIES. TRENDS ARE BEING MONITORED FOR
THE NEED FOR DOWNSTREAM WATCH ISSUANCE.
DISCUSSION...SEVERAL SEVERE WIND REPORTS HAVE BEEN NOTED OVER THE
PAST TWO HOURS ACROSS CENTRAL KS AS TWO PREDOMINANT BANDS/CLUSTERS
OF THUNDERSTORMS HAVE EMERGED AND SPREAD NORTHEAST. THESE CLUSTERS
CURRENTLY RESIDE WITHIN THE AXIS OF HIGHER MLCAPE AND SHOULD BE
MIGRATING TOWARDS A REGION OF LOWER BUOYANCY ACROSS EASTERN NE AND
FAR EASTERN KS (AS DEPICTED BY THE RECENT 00Z TOP RAOB THAT SAMPLED
AROUND 1800 J/KG MLCAPE ALONG WITH NEARLY -120 J/KG MLCIN). HOWEVER,
THE PRESENCE OF ESTABLISHED COLD POOLS WITH BOTH CLUSTERS, COMBINED
WITH THE COMING ONSET OF THE NOCTURNAL JET, MAY PROMOTE A CONTINUED
SEVERE WIND THREAT DOWNSTREAM ACROSS SOUTHEAST NE AND PARTS OF
EASTERN KANSAS THROUGH LATE EVENING. CONVECTIVE TRENDS WILL CONTINUE
TO BE MONITORED FOR THE NEED FOR DOWNSTREAM WATCH ISSUANCE.
FURTHER SOUTHWEST ACROSS SOUTH-CENTRAL KS, CONVECTION CONTINUES TO
DEVELOP ALONG THE OUTFLOW BOUNDARIES ASSOCIATED WITH THE INITIAL
THUNDERSTORM CLUSTERS. ALTHOUGH STORM MOTIONS WILL BE TOWARDS THE
CONVECTIVELY OVERTURNED/COLD POOL AIR, CONVECTIVE INTENSITY TRENDS
IN GOES CLOUD-TOP TEMPERATURES AND MRMS VIL SUGGEST THAT POCKETS OF
SUFFICIENT BUOYANCY REMAIN IN PLACE FOR AT LEAST A LOCALIZED HAIL
AND WIND THREAT OVER THE NEXT COUPLE OF HOURS - ESPECIALLY AS
ISENTROPIC UPGLIDE OVER THE COLD POOLS INCREASES WITH THE ONSET OF
THE NOCTURNAL JET.
