DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0729 PM CDT WED APR 30 2008
VALID 010100Z - 011200Z
...NO SVR TSTM AREAS FORECAST...
...CNTRL/NRN HIGH PLAINS...
00Z SOUNDINGS FROM THE HIGH PLAINS ARE QUITE DRY THIS
EVENING...THOUGH LAPSE RATE ENVIRONMENT IS CERTAINLY STEEP ENOUGH
FOR DEEP THERMALS ALONG/POST FRONTAL FROM ERN WY INTO WRN SD/NEB
PANHANDLE. LARGE SCALE ASCENT WILL INCREASE ACROSS THIS REGION AS
UPPER SPEED MAX DIGS INTO CO LATE TONIGHT WHICH SHOULD SERVE TO
COOL/MOISTEN MID LEVELS. ALTHOUGH SCATTERED LIGHTNING SHOULD BE
NOTED WITHIN EXPANDING PRECIPITATION SHIELD OVER THE HIGH
PLAINS...ESPECIALLY ACROSS THE NEB PANHANDLE...IT APPEARS THE
PROSPECT FOR DAMAGING WINDS AT THE SURFACE ARE TOO LOW TO WARRANT
MEANINGFUL SEVERE PROBABILITIES TONIGHT.
