CU BEGINNING TO FORM OVER THE WRN MOUNTAINS.  GIVEN THE AVAILABLE
MOISTURE AND WARM AFTERNOON TEMPERATURES FEEL THAT CAP OVER THOSE
AREAS WILL FINALLY BE ERODED LATE THIS AFTERNOON.  EXPECT THAT A
FEW SHOWERS AND THUNDERSTORMS WILL DEVELOP THERE FIRST LATE THIS
AFTERNOON AND EVENING.  MAIN CONCERN IS THAT SHOWERS AND
THUNDERSTORMS WILL BECOME MORE WIDESPREAD THIS EVENING AND TONIGHT
AS A SUBSTANTIAL COLD FRONT PUSHES THROUGH THE AREA.  THIS BOUNDARY
COMBINED WITH HIGH LAPSE RATES AND AN APPROACHING UPR LVL VORT MAX
WILL MAKE DEEP CONVECTION A POSSIBILITY THIS EVENING.  BY TOMORROW
MUCH COOLER AIRMASS AND UPSLOPE OVERRUNNING SITUATION WILL SET
UP...LEADING TO A COOL CLOUDY CONDITIONS THROUGH MOST OF THE NEAR
TERM FORECAST.

FOR THE EXTENDED...WEAK RIDGE BEGINS TO BUILD BACK INTO AREA BRINGING A
QUICK WARMUP.  HOWEVER...BY WEDNESDAY MODELS ADVERTISING ANOTHER
DEEP TROF TO BRING COOL CLOUDY CONDITIONS.  WILL HAVE TO WAIT AND
SEE AS MRF TYPICALLY NOT BEEN THAT GOOD AT DEPICTING THESE SYSTEMS.
FOR NOW WILL BEGIN A TREND BACK TO A COOL-OFF WITH MOSTLY CLOUDY
SKIES.
