DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0227 AM CDT TUE MAY 03 2016

VALID 051200Z - 061200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ISOLATED-SCATTERED THUNDERSTORMS ARE EXPECTED DURING THE DAY ACROSS
PORTIONS OF THE MIDDLE ATLANTIC AND SOUTHEASTERN STATES.  ISOLATED
THUNDERSTORMS ARE ALSO EXPECTED ACROSS PORTIONS OF THE WRN US
INCLUDING INTERIOR VALLEYS OF CALIFORNIA.

...DISCUSSION...

TWO MAIN AREAS OF CONVECTION ARE EXPECTED ACROSS THE CONUS DURING
THE DAY3 PERIOD.  BOTH REGIONS WHERE TSTMS SHOULD DEVELOP WILL OCCUR
IN ASSOCIATION WITH UPPER LOWS OVER NC AND OVER THE SWRN U.S.
DIURNAL HEATING BENEATH THE NC LOW WILL GENERATE STEEP LAPSE RATES
WHERE 500MB TEMPERATURES WILL BE AOB -20C.  SMALL HAIL COULD BE
NOTED WITH THE MORE ROBUST UPDRAFTS BUT INSTABILITY SHOULD PROVE
INADEQUATE FOR ORGANIZED SEVERE.

ACROSS THE WRN U.S...DAYTIME HEATING SHOULD CONTRIBUTE TO
DESTABILIZATION ACROSS MUCH OF THE ROCKIES AND GREAT BASIN.  COLD
MID-LEVEL TEMPERATURES BENEATH THE UPPER LOW OVER CA...AOB -20C AT
500MB...SHOULD ALSO CONTRIBUTE TO BUOYANCY OVER THE VALLEYS AIDING
ISOLATED THUNDERSTORMS ACROSS THIS REGION.  SMALL HAIL COULD BE
NOTED WITH THESE STORMS BUT OVERALL INTENSITY SHOULD REMAIN BELOW
SEVERE LEVELS.
