AREAS AFFECTED...SE WY...NE CO...WRN NEB

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 072003Z - 072130Z

TRENDS ARE BEING MONITORED FOR POSSIBILITY OF INCREASING SEVERE
THREAT.  WW IS NOT ANTICIPATED IN SHORT TERM...BUT MAY BE POSSIBLE
THIS EVENING.

CLOUD COVER HAS BEEN SLOW TO CLEAR WEST/NORTHWEST OF MCCOOK INTO
AREAS JUST WEST OF MULLEN...BUT FARTHER WEST...HEATING AND MOIST
UPSLOPE FLOW HAVE CONTRIBUTED TO WEAK/MODERATE DESTABILIZATION FROM
EXTREME NORTHEAST COLORADO THROUGH THE NEBRASKA PANHANDLE.  MIXED
LAYER CAPE NOW EXCEEDS 1000 J/KG...AND THIS SHOULD PROVIDE SUPPORT
FOR INTENSIFYING UPDRAFTS AS CONVECTION CONTINUES TO DEVELOP AWAY
FROM THE CHEYENNE WY AREA LATE THIS AFTERNOON. THOUGH DEVELOPMENT
IS SLOW...DEEP LAYER SHEAR BENEATH 40 TO 50 KT HIGH-LEVEL FLOW...ON
SOUTHERN FRINGE OF UPPER WESTERLIES...IS FAVORABLE FOR UPDRAFT
ROTATION.  AN ISOLATED SUPERCELL OR TWO COULD EVENTUALLY DEVELOP BY
THE 22-23Z TIME FRAME...ENHANCING POTENTIAL FOR LARGE HAIL/DAMAGING
WIND GUSTS.
