DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1122 PM CST SAT JAN 24 2009
VALID 251200Z - 261200Z
...NO SVR TSTM AREAS FORECAST...
...GREAT BASIN/CNTRL ROCKIES...
WEAK CONVECTIVE INSTABILITY WILL PERSIST ACROSS THE INTERIOR WEST
FROM NV...EWD INTO WRN PORTIONS OF COLORADO SUNDAY. THIS ZONE OF
BUOYANCY WILL GRADUALLY SAG SOUTH AND EAST AS HEIGHTS FALL IN
RESPONSE TO APPROACHING VORT MAX/SHORTWAVE TROUGH OVER CA...AND THE
GRADUAL INTENSIFICATION OF UPPER JET FROM CNTRL AZ INTO SRN CO.
FORECAST SOUNDINGS ACROSS THE GENERAL THUNDERSTORM AREA ARE VERY
SIMILAR TO PROFILES OBSERVED DURING THE DAY SATURDAY. BOUNDARY
LAYER HEATING NORTH OF MAIN JET AXIS AND SUFFICIENTLY MOIST LOW-MID
LEVELS SUGGEST JUST ENOUGH INSTABILITY FOR ROBUST SHOWERS CAPABLE OF
GENERATING LIGHTNING AT TIMES...ESPECIALLY DURING THE AFTERNOON AND
EVENING HOURS.
