CONCERNING...TORNADO WATCH 228...
VALID 050428Z - 050600Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 228 CONTINUES.
SUPERCELLS THAT DEVELOPED OVER THE HIGHER TERRAIN OF CO CONTINUE TO
MOVE NEWD TOWARD THE NEB/KS-CO BORDER LATE THIS EVENING. THE STORMS
ARE EMBEDDED IN A HIGHLY SHEARED ENVIRONMENT WITH 0-1KM SRH IN
EXCESS OF 600 M2/S2. THE STORMS APPEAR TO BE TRANSITIONING INTO A
MORE LINEAR MODE AS COLD POOLS BEGIN TO COLLECT AND NUMBER OF STORMS
INCREASE. PROSPECTS OF EMBEDDED SUPERCELL STRUCTURES WILL CONTINUE
OWING TO FAVORABLE BULK SHEAR...HOWEVER.
STORMS ARE EXPECTED TO CONTINUE INCREASING AS THEY MOVE ENEWD INTO
SWRN NEB AND NWRN KS...LARGELY TIED WITH ENHANCED UPPER SUPPORT
ASSOCD WITH APPROACHING MID-LEVEL IMPULSE. LOW-LEVEL THERMODYNAMIC
PROFILES FARTHER EAST ON THE PLAINS MORE THAN LIKELY CONTAIN
INCREASING INHIBITION...BUT THE THREAT FOR TORNADOES IS NON-ZERO.
OTHERWISE...LARGE HAIL AND HIGH WINDS CAN BE EXPECTED.
