..DISCUSSION FROM PHXFWFPSR
A DRY WEATHER SYSTEM WILL LEAD TO WIDESPREAD BREEZY TO LOCALLY WINDY
CONDITIONS TODAY. THE STRONGEST WESTERLY TO NORTHWESTERLY WINDS
(GUSTS >35 MPH) WILL BE THIS MORNING IN PARTS OF SOUTHEAST CA AND
SOUTHWEST AZ AND THIS AFTERNOON IN SOUTHERN GILA COUNTY. IN BOTH
AREAS, RH MAGNITUDES LOOK TO REMAIN ABOVE THE CRITICAL LEVEL (15%)
DURING THE PERIOD OF STRONGEST WINDS, THUS LIMITING THE FIRE WEATHER
RISK. STILL, THERE MAY BE SOME LOCALLY ELEVATED FIRE WEATHER
CONDITIONS IN SOUTHERN GILA COUNTY THIS AFTERNOON WITH SOME OF THE
LOWER ELEVATION SPOTS DIPPING BELOW 20% RH. ACROSS THE LOWER DESERTS
THIS AFTERNOON MINIMUM RH VALUES WILL FALL TO AROUND 15-20% IN
SOUTH-CENTRAL AZ AND 10-15% FURTHER WEST WITH WIND GUSTS UP TO
20-30 MPH. LINGERING BREEZINESS IS ANTICIPATED WEDNESDAY MORNING
THROUGH MIDDAY, WITH MORE OF A NORTHERLY TO NORTHEASTERLY COMPONENT,
BUT SPEEDS WILL BE NOTABLY LOWER THAN TODAY AND WILL GRADUALLY
SUBSIDE THROUGH THE AFTERNOON. CONDITIONS WILL REMAIN DRY WEDNESDAY,
WITH MINIMUM RH VALUES AROUND 10-15% REGION-WIDE. AFTERNOON
TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL TODAY AND TOMORROW, WITH
LOWER DESERT HIGHS IN THE LOW TO MID 70S.
NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
