SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


THROUGH MID WEEK...A LOW PRESSURE SYSTEM TO THE NORTH WILL BRING
SLIGHTLY STRONGER ONSHORE FLOW WITH SLOW COOLING AND GUSTY WEST
WINDS IN THE MOUNTAINS AND DESERTS EACH LATE AFTERNOON THROUGH LATE
EVENING. A WEAK COASTAL EDDY WILL BRING SLOW DEEPENING OF THE
MARINE LAYER INTO LOWER PORTIONS OF THE INLAND VALLEYS THROUGH
WEDNESDAY. TOWARD NEXT WEEKEND...HIGH PRESSURE TO THE SOUTH MAY
BEGIN TO EXPAND NORTHWARD BRINGING SLOW WARMING.


Discussion from LAXFWFLOX

TEMPERATURES OVER THE MAJORITY OF THE AREA TRENDED
SEVERAL DEGREES COOLER THAN SATURDAY AT THIS TIME AND THE RELATIVE
HUMIDITY TRENDED SLIGHTLY HIGHER. A WEAK TO MODERATE ONSHORE PRESSURE
GRADIENT WILL CONTINUE THROUGH THE EVENING AND THE STRONGEST WINDS
WILL OCCUR IN THE VICINITY OF THE I-5 CORRIDOR NORTH OF NEWHALL AND
IN THE ANTELOPE VALLEY. SINGLE DIGIT RELATIVE HUMIDITY IN THE MENTIONED
AREAS ARE EXPECTED TO RECOVER TO NEAR 40 PERCENT EARLY MONDAY
MORNING BUT IN THE MEANTIME A FEW HOURS OF CRITICAL FIRE WEATHER
CONDITIONS WILL EXIST. A WEAK SUNDOWNER IS EXPECTED OVER THE SANTA
YNEZ RANGE TONIGHT WITH LOCAL GUSTS TO 35 MPH AND THE RELATIVE
HUMIDITY IS EXPECTED IN THE MIDDLE TO UPPER TEENS WHICH WILL MAKE FOR A FEW
HOURS OF CRITICAL FIRE WEATHER CONDITIONS ALONG THE SANTA BARBARA
COUNTY SOUTH COAST SLOPES.

OTHERWISE THE MARINE LAYER IS EXPECTED TO DEEPEN TONIGHT AND RANGE
BETWEEN 1300 AND 1700 FEET ASL EACH NIGHT THROUGH THE PERIOD.
A COOLING TREND IS EXPECTED IN THE LOWER ELEVATIONS THROUGH WEDNESDAY
AND TEMPERATURES WILL DIFFER EACH DAY BY MINUS 2 TO 3 DEGREES AND LIKELY
RANGE 3 TO 5 DEGREES BELOW NORMAL BY WEDNESDAY. LITTLE CHANGE IS EXPECTED
IN THE HIGHER ELEVATIONS AND WILL LIKELY REMAIN ABOVE SEASONAL NORMAL.


Discussion from SFOFWFHNX

BREEZY CONDITIONS BELOW THE PASSES OF THE KERN COUNTY
MOUNTAINS WILL DIMINISH OVERNIGHT AS AN UPPER TROUGH IN THE GREAT BASIN
MOVES FURTHER AWAY FROM THE DISTRICT. OTHERWISE LIGHT AND TERRAIN DRIVEN
WINDS WILL PREVAIL OVER THE REMAINDER OF THE DISTRICT. A RIDGE ALONG THE
PACIFIC WILL BUILD INLAND OVER CALIFORNIA STARTING MONDAY AND USHER IN A
WARM AND DRY TREND FOR MUCH OF WORK WEEK.


Discussion from RNOFWFVEF

WARM AND DRY CONDITIONS WILL CONTINUE THROUGH THE WEEK.
MONSOON MOISTURE SEEPING BACK INTO NORTHWEST ARIZONA WILL BRING A
RETURNED CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE LATTER HALF OF
THE UPCOMING WEEKEND.


Discussion from PHXFWFPSR


VERY DRY WESTERLY FLOW ALOFT WILL CONTINUE TO PROVIDE CLEAR SKIES AND
UNSEASONABLY LOW HUMIDITY TO THE REGION TODAY AND TUESDAY. MINIMUM
RELATIVE HUMIDITIES WILL CONTINUE IN THE 10 PERCENT RANGE AS
UNSEASONABLY WARM AFTERNOON TEMPERATURES PERSIST. LIGHT AFTERNOON
SOUTHWEST BREEZES IN THE 7 TO 12 MPH RANGE ARE FORECAST. GOOD
OVERNIGHT RECOVERY IS EXPECTED.

...THUNDERSTORMS IMPLY GUSTY WINDS...

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