AREAS AFFECTED...ERN CO

CONCERNING...SEVERE THUNDERSTORM WATCH 477...

VALID 260143Z - 260315Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 477
CONTINUES.

SUMMARY...LINE OF TSTMS MOVING EWD ACROSS ERN CO WILL LIKELY PERSIST
FOR THE NEXT FEW HOURS. OVERALL SVR THREAT APPEARS TO BE DIMINISHING
BUT SOME ISOLATED DAMAGING WIND GUSTS ARE STILL POSSIBLE.

DISCUSSION...THE AIRMASS DOWNSTREAM OF THE LINE OF TSTMS MOVING EWD
THROUGH ERN CO REMAINS UNSTABLE WITH SPC MESOANALYSIS ESTIMATING
MLCAPE AROUND 1000 J PER KG. AS DAYTIME HEATING WANES...CINH WILL
INCREASE ACROSS THE AREA BUT RECENT TSTM ACTIVITY IN NW KS INDICATES
CINH REMAINS LOW. THIS DOWNSTREAM INSTABILITY COUPLED WITH AN
INCREASING LOW-LEVEL JET AND POTENTIAL INTERACTION WITH NWD
PROGRESSING OUTFLOW BOUNDARY FROM TSTMS IN CNTRL KS WILL HELP
MAINTAIN THE LINE AS IT CONTINUES EWD IN FAR SWRN NEB AND NW KS.
SOME ISOLATED DAMAGING WIND GUSTS REMAIN POSSIBLE.
