TODAY AND TONIGHT. WINDS WILL COME OUT OF THE SOUTHWEST THIS
AFTERNOON BRINGING JUST A SLIGHT INCREASE IN MOISTURE. THIS SHOULD
HELP KEEP MINIMUM HUMIDITY JUST ABOVE CRITICAL THRESHOLDS TODAY. A
COLD FRONT WILL THEN APPROACH THE BURN AREA FRIDAY CAUSING AN
INCREASE IN WINDS. HUMIDITY WILL REMAIN LOW AS WELL IN ADVANCE OF
THE FRONT. THE FRONT WILL PASS THROUGH THE AREA ALONG WITH A
WEAKENING LINE OF SHOWERS AND THUNDERSTORMS FRIDAY NIGHT. RAINFALL
AMOUNTS CONTINUE TO LOOK MEAGER... GENERALLY A QUARTER INCH OR LESS.
