DISCUSSION
THIS WEEKEND, GUSTS WILL BE UPWARDS OF 35 MPH FOR MUCH OF THE
AREA. HOWEVER, AN INFLUX OF MOISTURE WILL NEGATE THE POTENTIAL FOR
WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS DUE TO RISING RH.
PRECIPITATION CHANCES WILL BE ISOLATED TODAY AND TRANSITION TO
SCATTERED BY SUNDAY AFTERNOON/EVENING. MORE WIDESPREAD
PRECIPITATION CHANCES MAKE A RETURN MONDAY FOR MUCH OF THE REGION.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
