AREAS AFFECTED...ERN NEB...SRN IA...NRN MO...NE KS
CONCERNING...SEVERE THUNDERSTORM WATCH 276...
VALID 202342Z - 210045Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 276
CONTINUES.
SUMMARY...THREAT FOR ISOLATED DAMAGING WINDS AND LARGE HAIL WILL
PERSIST FOR THE NEXT FEW HOURS...FOCUSING PRIMARILY INTO NRN MO AND
PERHAPS EXTENDING A TIER OR TWO OF COUNTIES S OF THE EXISTING WATCH.
FARTHER N...THE RISK FOR LARGE HAIL SHOULD DIMINISH SLOWLY ACROSS
ERN NEB AND SRN IA.
DISCUSSION...BANDS OF ELEVATED CONVECTION N OVER ERN NEB AND SW IA
/TO THE N OF THE SURFACE COLD FRONT/ ARE LIKELY PAST PEAK
INTENSITY...AND SHOULD DIMINISH THIS EVENING GIVEN ONLY WEAK WAA
PATTERN ABOVE THE FRONTAL SURFACE. THE MORE INTENSE STORMS ARE
EXPECTED TO FOCUS ALONG THE COLD FRONT AND PRE-FRONTAL TROUGH ACROSS
NRN MO...WITH SOME THE STORMS LIKELY SHIFTING A LITTLE S OF THE
EXISTING WATCH AREA. MODERATE BUOYANCY AND DEEP-LAYER NWLY SHEAR
WILL HELP MAINTAIN A RISK FOR ORGANIZED MULTICELL CLUSTERS WITH AN
ATTENDANT DAMAGING WIND/HAIL RISK FOR THE NEXT FEW HOURS INTO NRN
MO...WHERE A LOCAL EXTENSION OF THE WATCH MAY NEED TO BE CONSIDERED
NEAR THE I-70 CORRIDOR.
