AREAS AFFECTED...NE CO...NW KS...WRN/CNTRL/NRN NEB

CONCERNING...SEVERE THUNDERSTORM WATCH 408...

VALID 100154Z - 100330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 408
CONTINUES.

SUMMARY...LARGE HAIL AND DAMAGING WIND THREAT WILL CONTINUE ACROSS
MOST OF THE WATCH AREA. DESPITE DIURNAL COOLING...AN INCREASING LLJ
WILL LIKELY SUPPORT A CONTINUATION OF THE TSTM ACTIVITY ACROSS NEB
AND NW KS. TSTMS MOVING OUT OF NE CO HAVE BEEN WEAKENING BUT TRENDS
WILL BE MONITORED FOR A POSSIBLE INCREASE IN STRENGTH AND RESULTANT
NEED FOR A DOWNSTREAM WW.

DISCUSSION...RECENT RADAR IMAGERY ACROSS NEB CONTINUES TO SHOW
STRONG TO SVR TSTMS WITH SEVERAL REPORTS OF VERY LARGE HAIL AND
SEVERE WIND OVER THE LAST HOUR. DIURNAL COOLING WILL LIKELY LEAD TO
THE GRADUAL DECREASE IN TSTM COVERAGE AND INTENSITY. HOWEVER...SOME
OF THIS DECREASE MAY BE OFFSET BY AN INCREASE IN THE LLJ ACROSS WRN
KS AND WRN/CNTRL NEB WITH RESULTANT WAA OVER OUTFLOW BOUNDARIES
FAVORING CONTINUED TSTM DEVELOPMENT. RECENT TSTM DEVELOPMENT ACROSS
LOUP...ROCK...AND HOLT COUNTIES IN N-CNTRL NEB MAY BE A RESULT OF
THIS PROCESS. ANY STORMS THAT DEVELOP LATER WILL MAINLY POSE A SVR
HAIL THREAT...ALTHOUGH SOME DAMAGING WIND GUSTS WOULD STILL BE
POSSIBLE.

LINE OF STORMS ENTERING KIT CARSON AND YUMA COUNTIES IN NE CO HAD
PREVIOUSLY SHOWN SIGNS OF BETTER ORGANIZATION BUT CURRENT RADAR
IMAGERY SHOWS THE OUTFLOW IS BEGINNING TO SURGE AHEAD OF THE MAIN
LINE. SOME HAIL AND DAMAGING WINDS ARE POSSIBLE INTO W-CNTRL KS.
INTERACTION WITH THE LLJ MAY RESULT IN A DOWNSTREAM THREAT ACROSS SW
KS BUT CURRENT TRENDS SUGGEST A GRADUAL DISSIPATION OF THESE STORMS.
TRENDS WILL BE MONITORED FOR POSSIBLE DOWNSTREAM WW ISSUANCE ACROSS
SW KS.
