..DISCUSSION FROM PHXFWFPSR
ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS ARE EXPECTED TO
CONTINUE THROUGH THE FIRST HALF OF THIS WEEK. WINDS WILL REMAIN
MOSTLY BELOW 15 MPH TODAY, BUT ARE EXPECTED TO INCREASE ACROSS THE
REGION ON TUESDAY, ESPECIALLY ACROSS THE WESTERN DISTRICTS WHERE
GUSTS COULD REACH 20-30 MPH RESULTING IN ELEVATED FIRE WEATHER
CONDITIONS. MINRHS WILL BOTTOM OUT AROUND 10-15% TODAY AND 8-12% ON
TUESDAY. OVERNIGHT RECOVERIES WILL RANGE FROM POOR TO FAIR OR
GENERALLY BETWEEN 30-50% OVER THE NEXT COUPLE NIGHTS.
NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
