...DISCUSSION FROM RNOFWFVEF...

ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS
THE EASTERN HALF OF OUR FORECAST AREA TODAY AS A LOW PRESSURE SYSTEM
CONTINUES TO MOVE THROUGH THE AREA. MINIMUM RELATIVE HUMIDITIES WILL
BOTTOM IN THE SINGLE DIGITS TO MID-  TEENS ACROSS THE WESTERN HALF
OF OUR FORECAST AREA, WITH  AFTERNOON RELATIVE HUMIDITIES IN THE
25 TO 50 PERCENT RANGE ACROSS THE EASTERN HALF OF OUR FOREST AREA
WHERE MOISTURE REMAINS IN  PLACE. WEDNESDAY ONWARD WE WILL WARM UP
AND DRY OUT WITH LIGHTER  WINDS ACROSS THE REGION AS HIGH PRESSURE
BUILDS OVER THE  SOUTHWESTERN US. THESE DRY, WARM, AND MILD
CONDITIONS WILL  CONTINUE THROUGH THE WEEKEND.


...DISCUSSION FROM LAXFWFSGX...


STRENGTHENING HIGH PRESSURE ALOFT WILL BRING A WARMING TREND WITH A
LONG-DURATION HEAT WAVE LIKELY FOR THIS WEEKEND THROUGH MUCH OF NEXT
WEEK INTO THE FOLLOWING WEEKEND. THERE COULD BE PERIODS OF  GUSTY
EAST WINDS ALONG AND BELOW THE COASTAL SLOPES OF THE  MOUNTAINS INTO
THE INLAND VALLEYS WITH GUSTS TO 25 TO 35 MPH ON  SATURDAY AND 30 TO
40 MPH ON SUNDAY WITH LOWEST DAYTIME RELATIVE  HUMIDITY FOR THE
COASTAL SLOPES OF THE MOUNTAINS INTO THE VALLEYS  FALLING TO 15 TO
25 PERCENT WITH ELEVATED FIRE WEATHER CONDITIONS. THERE COULD BE
ADDITIONAL PERIODS OF MOSTLY WEAK OFFSHORE FLOW  NEXT WEEK, BUT WITH
LOWER CONFIDENCE IN THE TIMING AND OTHER  DETAILS.


...DISCUSSION FROM PHXFWFPSR...


WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS WILL AFFECT MUCH OF
THE AREA EARLY TODAY BEFORE MAINLY AFFECTING THE ARIZONA HIGH
TERRAIN THIS AFTERNOON AND EVENING. MODERATE TO HEAVY RAINFALL IS
LIKELY TO IMPACT THE ARIZONA HIGH TERRAIN THROUGH AT LEAST EARLY
AFTERNOON. HUMIDITIES WILL BEGIN TO TREND LOWER ACROSS THE WESTERN
DISTRICTS LATER TODAY, BUT MORE SO ON WEDNESDAY. ELEVATED HUMIDITIES
WILL PERSIST ACROSS THE EASTERN DISTRICTS THROUGH AT LEAST THURSDAY.
WINDS WILL BE BREEZY TO LOCALLY WINDY AT TIMES  TODAY BEFORE
BECOMING LIGHT AGAIN ON WEDNESDAY.
