CONCERNING...SEVERE THUNDERSTORM WATCH 128...
VALID 172007Z - 172100Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 128
CONTINUES.
SUMMARY...SEVERE THREAT CONTINUES WITH WW128.
DISCUSSION...THUNDERSTORM ACTIVITY CONTINUES ALONG THE COLD FRONT
WITHIN WW128. A MIXED MODE OF CLUSTERS AND ISOLATED SUPERCELLS
CONTINUES. HAIL AROUND 1-1.5 INCHES IN DIAMETER HAS BEEN REPORTED.
THE PRIMARY RISK WILL BE FOR LARGE HAIL AND DAMAGING WIND, GIVEN THE
DECREASING MOISTURE WITH NORTHWARD EXTENT FAIRLY MARGINAL LOW-LEVEL
SHEAR. HOWEVER, A TORNADO CANNOT BE RULED OUT, ESPECIALLY WITH ANY
MORE DISCRETE SUPERCELL. THROUGH TIME, AS THE FRONT SHIFTS EASTWARD
THE PRIMARY THREAT WILL SHIFT TO DAMAGING WIND.
