THE 30S. DAYTIME HIGHS WILL BEGIN TO RISE INTO THE 60S UNDER SUNNY SKIES
AND SW WINDS...AS A WEAK COLD FRONT BEGINS TO MOVE ACROSS THE

LVL CLOUDINESS. GIVEN THESE MINOR SHORTWAVES IN OVERALL PATTERN...
LOOKING AT MOSTLY CLEAR SKIES EXCEPT FOR A FEW HIGHER CLOUDS...AND FAIRLY
PERSISTENT TEMPS...THROUGH THANKSGIVING. HOWEVER...A WARMING TREND
UNDERWAY FOR THE WEEKEND...WITH GRADUALLY INCREASING LOW LVL
MOISTURE THAT WILL EVENTUALLY BRING ABOUT A SLIGHT CHANCE OF
