AREAS AFFECTED...PORTIONS OF CENTRAL NEBRASKA
CONCERNING...SEVERE THUNDERSTORM WATCH 633...
VALID 280047Z - 280145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 633
CONTINUES.
SUMMARY...AN ORGANIZING BOWING CLUSTER MAY PRODUCE SIGNIFICANT
SEVERE GUSTS (75-90 MPH) AS IT MOVES TOWARD THE I-80 CORRIDOR OVER
THE NEXT 1-2 HOURS.
DISCUSSION...A CLUSTER OF FORMERLY HP SUPERCELLS OVER CENTRAL NE HAS
MERGED AND STARTED TO ORGANIZE INTO A LINEAR COMPLEX OVER THE LAST
30 MIN. RECENT KLNX RADAR DATA SHOWS A DEVELOPING WEAK REFLECTIVELY
NOTCH CONCURRENT WITH INCREASING OUTBOUND VELOCITIES OF 70+ KT AT
1-2 KFT AGL. THIS IS SUGGESTIVE OF A RAPIDLY ORGANIZING COLD POOL
AND REAR INFLOW JET. GIVEN THE FAVORABLE ENVIRONMENT WITH MLCAPE IN
EXCESS OF 3000 J/KG AND T/TD SPREADS OF 20+ DEGREES F, SIGNIFICANT
DAMAGING WIND POTENTIAL IS LIKELY INCREASING. SEVERE GUSTS OF 75-90+
MPH WILL BE POSSIBLE NEAR THE APEX OF THE BOWING CLUSTER AS IT MOVES
TOWARD THE I-80 CORRIDOR OVER THE NEXT HOUR. IF THE CLUSTER IS ABLE
TO PERSIST, A SMALL DOWNSTREAM WATCH COULD BE NEEDED SOUTH OF WW633
