...DISCUSSION FROM RNOFWFVEF...

SOUTHERLY WINDS WILL DEVELOP THURSDAY AFTERNOON WITH GUSTS OF
30-35 MPH ACROSS MUCH OF THE AREA. EXTREMELY DRY CONDITIONS WILL
CONTINUE WITH DAYTIME RH IN THE SINGLE DIGITS AND LIMITED RECOVERY
OVERNIGHT. WHAT RECOVERY DOES OCCUR WILL BE MAINLY DUE TO OVERALL
COOLING TEMPERATURES DUE TO AN APPROACHING TROUGH OF LOW PRESSURE
RATHER THAN INCREASING MOISTURE.


...DISCUSSION FROM LAXFWFSGX...


HIGH PRESSURE WILL MOVE TO THE EAST AS A LARGE TROUGH OF LOW
PRESSURE MOVES IN FROM THE NORTH. THIS WILL HELP TO SUBTLY INCREASE
AFTERNOON RELATIVE HUMIDITY VALUES 10 TO 15 PERCENT ACROSS THE
DESERT SLOPES OF THE MOUNTAINS THROUGH THE END OF THE WEEK WITH
VALUES NEAR 20 TO 25  PERCENT. ELEVATED FIRE WEATHER CONDITIONS WILL
CONTINUE AS DRY WEATHER CONTINUES WITH ELEVATED WIND GUSTS IN THE
MOUNTAINS AND DESERTS NEAR  25-40 MPH. THE MARINE LAYER WILL BE
DEEPER THROUGH THE WEEKEND AS WELL WITH NIGHT AND MORNING LOW CLOUDS
WEST OF THE MOUNTAINS. SLOW WARMING IS EXPECTED BY THE MIDDLE OF
NEXT WEEK AS WEAKER HIGH PRESSURE MOVES IN OFF THE COAST.


...DISCUSSION FROM PHXFWFPSR...


HOT AND DRY CONDITIONS WILL CONTINUE OVER THE NEXT FEW DAYS WITH
OVERALL LIGHT DIURNAL WINDS TODAY. STARTING THURSDAY, WINDS WILL
INCREASE MODESTLY WITH AFTERNOON GUSTS UP TO AROUND 20 MPH, AND
THEN UP TO AROUND 25 MPH ON FRIDAY. HUMIDITIES WILL STAY LOW WITH
MINRHS BETWEEN 5-10% AND OVERNIGHT MAXRHS ONLY BETWEEN 15-30%.
AFTERNOON GUSTS COMBINED WITH THE DRY CONDITIONS MAY RESULT IN
ELEVATED TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS, ESPECIALLY
ACROSS THE HIGHER TERRAIN EAST OF PHOENIX ON FRIDAY. TEMPERATURES
WILL REMAIN ABOVE NORMAL WITH HIGHS NEAR OR ABOVE 110 DEGREES
ACROSS THE LOWER DESERTS THROUGH FRIDAY.
