VALID 231200Z - 241200Z.

...NO TSTM AREAS FORECAST...

A PRIMARILY ZONAL FLOW PATTERN WILL REMAIN IN PLACE ACROSS THE CONUS
THROUGH THE DAY 2 PERIOD. ON A FINER SCALE...A SHORTWAVE TROUGH
EMBEDDED IN THE WLY-S IS FORECAST TO AMPLIFY IN THE NRN ROCKIES
TONIGHT. AS THE WAVE PASSES BY LATE TONIGHT INTO
FRIDAY...LARGE-SCALE ASCENT ASSOCIATED WITH THE WAVE SHOULD BE
SUFFICIENT TO HELP INITIATE VERY ISOLATED CONVECTION IN THE HIGHER
TERRAIN OF WY AND CO AS TEMPS WARM FRIDAY LATE MORNING INTO THE
EARLY AFTERNOON. HOWEVER...VERY LIMITED MOISTURE SHOULD KEEP ANY
LIGHTNING COVERAGE BELOW THE 10 % THRESHOLD. 

IN SOUTH TX...THE NAM DEVELOPS ENOUGH INSTABILITY FOR CONVECTION FOR
THE DAY 2 PERIOD. HOWEVER...THIS APPEARS TO BE OVERDONE CONSIDERING
SFC DEWPOINTS ARE STILL IN THE 40S AND 50S F ACROSS THE REGION. IN
ADDITION...A CAPPING INVERSION IS EXPECTED TO REMAIN IN PLACE AND
CONVECTIVE DEVELOPMENT APPEARS UNLIKELY FRIDAY OR FRIDAY NIGHT
ACROSS SOUTH TX. 

ELSEWHERE ACROSS THE CONUS...LIGHTNING ACTIVITY IS NOT EXPECTED
FRIDAY OR FRIDAY NIGHT.
