DISCUSSION
FLUCTUATING TEMPERATURES WITH BREEZY TO LOCALLY WINDY CONDITIONS
CAN BE EXPECTED THROUGH THE END OF THE WORKWEEK/START OF THE
WEEKEND. MINRH VALUES WILL HOVER BETWEEN 10% AND THE UPPER-TEENS
THE NEXT FEW AFTERNOON WITH POOR TO MODEST OVERNIGHT RECOVERY.
WIDESPREAD WIND GUSTS THROUGH THE REMAINDER OF TODAY WILL RANGE
BETWEEN 25-35 MPH, WITH SIMILAR GUSTS BEING OBSERVED TOMORROW,
THIS TIME FOCUSED AROUND THE WESTERN DISTRICTS. THE COMBINATION OF
LOW RH AND ELEVATED WINDS WILL CREATE INSTANCE OF ELEVATED TO
NEAR CRITICAL FIRE WEATHER CONDITIONS. HOWEVER, FUEL MOISTURE'S
REMAIN RELATIVELY HIGH AND SHOULD LIMIT SIGNIFICANT FIRE
POTENTIAL. TEMPERATURES WILL COOL TO NEAR AND EVEN BELOW NORMAL BY
FRIDAY BEFORE QUICKLY INCREASING AGAIN BY SATURDAY.
..THUNDERSTORMS IMPLY GUSTY WINDS
