..DISCUSSION FROM RNOFWFVEF
STRONG WESTERLY-TO-SOUTHWESTERLY WINDS WILL IMPACT THE REGION TODAY
AS A LOW PRESSURE SYSTEM MOVES THROUGH THE AREA. IN ADDITION TO
GUSTY WINDS, THIS SYSTEM WILL BRING INCREASED CHANCES FOR LIGHT
PRECIPITATION TO THE NORTHERN HALF OF OUR FORECAST AREA. WINDS WILL
SHIFT TO THE NORTHWEST OVERNIGHT AS WE FIND OURSELVES ON THE BACK
SIDE OF THIS SYSTEM. MUCH DRIER AIR WILL PUSH INTO THE REGION IN THE
WAKE OF THIS LOW PRESSURE SYSTEM. THE SECOND HALF OF THE WEEK WILL
BE CHARACTERIZED BY DRY CONDITIONS, AFTERNOON BREEZES, AND
TEMPERATURES GRADUALLY CLIMBING BACK TO MORE SEASONAL VALUES.
..DISCUSSION FROM LAXFWFSGX
ONSHORE FLOW AND HUMIDITY WILL INCREASE TODAY, BOOSTING WINDS IN ALL
AREAS, ESPECIALLY THE MOUNTAINS AND DESERTS AND IMMEDIATE COAST.
LIGHT SHOWERS, BARELY WETTING RAINS FOR SOME AREAS, WILL QUICKLY
MOVE THROUGH THE REGION (EXCEPT THE DESERTS) BETWEEN 4 PM AND 10 PM
LATE TODAY. DRY AND WARMER WEATHER RETURNS TUESDAY, WITH SOME
OFFSHORE FLOW AND LOCAL NORTHEAST BREEZES IN THE FOOTHILLS
WEDNESDAY MORNING, DROPPING HUMIDITY. BRISK ONSHORE FLOW AND HIGHER
HUMIDITY RETURN FOR THURSDAY AND FRIDAY. ONSHORE FLOW WEAKENS OVER
THE WEEKEND AND HIGH PRESSURE AMPLIFIES NEXT WEEK FOR MUCH WARMER
WEATHER BUT LIGHT WINDS.
..DISCUSSION FROM PHXFWFPSR

WILL CONTINUE THROUGH TONIGHT ACROSS WESTERN DISTRICTS, WITH BREEZY
CONDITIONS ALSO SPREADING EASTWARD, AND THEN THERE WILL BE A PERIOD
AROUND MIDDAY TO EARLY AFTERNOON TOMORROW WHEN NW WIND GUSTS WILL
STILL BE AROUND 25-30 MPH WHILE RH VALUES DIP TO 10-15%. WIND GUSTS
UP TO 30-40 MPH ARE ALSO ANTICIPATED IN PARTS OF SOUTHERN GILA
