...DISCUSSION FROM PHXFWFPSR...


A SHORT-WAVE TROUGH MOVING THROUGH THE REGION TODAY WILL GENERATE
WIDESPREAD BREEZY TO LOCALLY WINDY CONDITIONS. STRONGEST WIND GUSTS
MAY BE GENERATED BY A BAND OF HIGH-BASED SHOWERS IN SOUTH-  CENTRAL
AZ THIS AFTERNOON, WITH 40-50% CHANCE FOR SOUTHWESTERLY  GUSTS IN
EXCESS OF 40 MPH, PRIMARILY BETWEEN 1300-1700MST. THERE  MAY BE A
BRIEF PERIOD, UP TO 2-3 HOURS IN EASTERN DISTRICTS DURING THE EARLY
TO MID AFTERNOON, WITH CRITICAL FIRE WEATHER  CONDITIONS. OUTSIDE OF
SHOWER-GENERATED GUSTS, WIDESPREAD WIND  GUSTS, ACROSS ALL
DISTRICTS, UP TO 25-35 MPH ARE ANTICIPATED WITH  SOME LOCALIZED
AREAS LIKE THE IMPERIAL VALLEY SEEING UP TO 35-40  MPH. THIS WILL
RESULT IN WIDESPREAD ELEVATED FIRE WEATHER,  BORDERLINE RED FLAG,
CONDITIONS TODAY AS MINIMUM RHS FALL TO  10-15%. THE CHANCE FOR
WETTING RAIN IS NEAR ZERO AS THERE WILL BE A LOT OF SUB-CLOUD
EVAPORATION BEFORE REACHING THE SURFACE. LAND  MANAGERS SHOULD BE
CAUTIOUS FOR RAPID, UNCONTROLLED SPREAD OF ANY  ONGOING FIRES OR NEW
STARTS MONDAY. WINDS WILL SUBSIDE FAIRLY  QUICKLY THIS EVENING AND
SPEEDS WILL NOT BE AS STRONG TUESDAY, BUT STILL WITH AFTERNOON GUSTS
UP TO 15-25 MPH. DIRECTIONS TUESDAY  WILL FOLLOW TYPICAL AND TERRAIN
INFLUENCES. IT WILL BE DRIER  TUESDAY, WITH MINIMUM AFTERNOON RH
VALUES DOWN TO 5-12%

NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
