SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


WEAK ONSHORE FLOW WILL MAINTAIN HIGHER HUMIDITIES AND COOLER
TEMPERATURES NEAR THE COAST THIS AFTERNOON...WHILE INLAND AREAS
SLOWLY WARM AND OFFSHORE PRESSURE GRADIENTS BEGIN TO DEVELOP.
HIGH PRESSURE ALOFT AND OFFSHORE FLOW WITH LOCALLY GUSTY NORTHEAST
WINDS WILL BRING MUCH WARMER AND DRIER CONDITIONS FOR THURSDAY
THROUGH SUNDAY. WINDS WILL BE STRONGEST THURSDAY
MORNING...GRADUALLY WEAKENING FRIDAY AND SATURDAY. HUMIDITIES WILL
DECREASE ON THURSDAY...REACHING SINGLE DIGITS ACROSS INLAND AREAS
BY THURSDAY AFTERNOON. VERY LOW HUMIDITIES WILL CONTINUE THROUGH
SATURDAY WITH POOR OVERNIGHT RECOVERY. HIGH PRESSURE ALOFT WILL
BRING HIGHER TEMPERATURES THURSDAY THROUGH SUNDAY...WITH FRIDAY
AND SATURDAY BEING THE WARMEST DAYS. SLOW COOLING MAY BEGIN NEAR
THE BEACHES ON SUNDAY WITH SOME RELATIVE HUMIDITY RECOVERIES NEAR
THE COAST... SPREADING SLOWLY INLAND THROUGH EARLY NEXT WEEK.


Discussion from LAXFWFLOX


A TROUGH CURRENTLY MOVING THROUGH IDAHO WILL DEPOSIT HIGH
PRESSURE FORMING COLD AIR INTO THE GREAT BASIN LATER TODAY THROUGH
THURSDAY...WHICH WILL BRING GUSTY OFFSHORE FLOW TO SOUTHERN
CALIFORNIA. THESE NORTHEAST WINDS WILL START TO FORM TODAY OVER
INTERIOR LOS ANGELES COUNTY...WHICH COULD PRODUCE A FEW HOURS OF
CRITICAL CONDITIONS OVER THE SANTA CLARITA VALLEY AS HUMIDITIES
START TO DROP. THESE WINDS WILL STRENGTHEN AND PUSH DOWN INTO THE
VALLEY AND COASTAL SECTIONS TONIGHT THROUGH THURSDAY. WINDS ARE
GENERALLY EXPECTED TO BE OF THE 15 TO 25 MPH WITH GUSTS TO 35 MPH
VARIETY. MEANWHILE...A RIDGE OF HIGH PRESSURE WILL BUILD OVER
CALIFORNIA AND BRING HOT AND VERY DRY CONDITIONS TO THE
REGION...WITH HUMIDITIES AROUND 10 PERCENT OVER MOST AREAS BY
THURSDAY AFTERNOON. AS A RESULT...WIDESPREAD CRITICAL CONDITIONS ARE
LIKELY OVER MUCH OF LOS ANGELES AND VENTURA COUNTIES ON THURSDAY.
MOUNTAIN AND VALLEY AREAS HAVE THE BEST CHANCE TO EXCEED THE 6 HOUR
DURATION THRESHOLDS...BUT SOME COASTAL AREAS SHOULD SEE A FEW HOURS
OF CRITICAL CONDITIONS AS WELL. SAN LUIS OBISPO AND SANTA BARBARA
COUNTIES WILL HAVE ELEVATED FIRE CONCERNS AS WELL WITH HOT AND VERY
DRY CONDITIONS...BUT WINDS WILL BE WEAKER AND VERY
LOCALIZED...MOSTLY CONFINED TO SELECT INTERIOR VALLEY AND MOUNTAIN
LOCATIONS.

CONDITIONS WILL BECOME HOTTER AND DRIER THURSDAY NIGHT THROUGH
SATURDAY...BUT THE WINDS WILL WEAKEN EACH DAY. THERE IS A CHANCE
THAT RED FLAG CONDITIONS WILL CONTINUE THURSDAY NIGHT THROUGH
FRIDAY...BUT LESS CERTAIN THAN THURSDAY DUE TO THE WEAKER WINDS.
REGARDLESS...TRIPLE DIGIT TEMPERATURES AND WIDESPREAD SINGLE DIGIT
HUMIDITIES WILL MAINTAIN A PERIOD OF ELEVATED FIRE CONCERN. COOLING
AND MOISTENING EXPECTED GRADUALLY NEXT WEEK.


Discussion from SFOFWFHNX

A WARMING AND DRYING TREND WILL CONTINUE OVER THE
REGION INTO THE WEEKEND AS HIGH PRESSURE BUILDS OVER THE AREA.
GUSTY OFFSHORE WINDS WILL BE PRESENT OVER THE KERN COUNTY MOUNTAIN
AND DESERT LATER THIS EVENING...RESULTING IN SLIGHTLY ELEVATED FIRE
DANGER. BEGINNING THURSDAY EVENING MOISTURE LEVELS WILL DROP TO
SINGLE DIGIT HUMIDITIES FOR UP TO 12 HOURS IN THE KERN COUNTY MOUNTAINS
AND THE SOUTHERN HALF OF THE TULARE COUNTY MOUNTAINS INCLUDING THE
SEQUOIA NATIONAL FOREST INCREASING THE FIRE DANGER IN THESE AREAS.
OTHERWISE...WINDS OVER KERN COUNTY ARE FORECAST TO WEAKEN OVERNIGHT
BUT REMAIN OFFSHORE INTO THE WEEKEND.



Discussion from RNOFWFVEF

LOCALLY GUSTY NORTH WINDS WILL CONTINUE THROUGH
THURSDAY ALONG WITH SLIGHTLY COOLER TEMPERATURES. HIGH PRESSURE
BUILDING OVERHEAD THIS WEEKEND WILL PRODUCE DRY AND WARM WEATHER.


Discussion from PHXFWFPSR


DRY CONDITIONS...CLEAR SKIES AND SLIGHTLY BELOW NORMAL TEMPERATURES
WILL PREVAIL THROUGH FRIDAY. LOCALLY BREEZY CONDITIONS FROM THE
NORTH AND NORTHEAST WILL DEVELOP THURSDAY MORNING ACROSS RIDGE TOPS
AND DOWN THE COLORADO RIVER VALLEY...BEFORE GENERALLY WEAKENING FRIDAY.
A MUCH DRIER AIRMASS WILL BECOME ESTABLISHED ACROSS THE REGION...WITH
MINIMUM HUMIDITY VALUES FALLING INTO THE SINGLE DIGITS AND TEENS BY
FRIDAY AFTERNOON.

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