SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


HIGH PRESSURE ALOFT AND OFFSHORE FLOW WITH GUSTY NORTHEAST WINDS
WILL BRING HOT AND DRY CONDITIONS THROUGH SUNDAY. WINDS WILL BE
QUITE GUSTY TODAY AND FRIDAY...BUT WILL DIMINISH SATURDAY. MINIMUM
RELATIVE HUMIDITIES WILL BOTTOM OUT IN THE SINGLE DIGITS FOR
INLAND VALLEY AND MOUNTAIN AREAS THROUGH SATURDAY...ALONG WITH
VERY POOR OVERNIGHT RECOVERIES. A SLOW COOLING TREND WILL BEGIN
SUNDAY NEAR THE COAST WITH THE ENTIRE REGION REACHING NEAR NORMAL
CONDITIONS BY MID NEXT WEEK AS ONSHORE FLOW STRENGTHENS.


Discussion from LAXFWFLOX



SURFACE HIGH PRESSURE FORMING OVER THE GREAT BASIN WILL BRING
GUSTY OFFSHORE FLOW TO SOUTHERN CALIFORNIA. THESE NORTHEAST WINDS
HAVE ALREADY FORMED OVER INTERIOR LOS ANGELES COUNTY...AND WILL
PUSH DOWN INTO THE VALLEY AND COASTAL SECTIONS TONIGHT THROUGH
THURSDAY. MEANWHILE A RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD
OVER CALIFORNIA...BRINGING 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.

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 TODAY ALONG WITH
SLIGHTLY BELOW NORMAL TEMPERATURES. HIGH PRESSURE BUILDING OVER THE
REGION THIS WEEKEND WILL PRODUCE DRY AND WARM WEATHER. MINIMUM
RELATIVE HUMIDITY VALUES BELOW 10 PERCENT WILL BE COMMON AT LOWER
ELEVATIONS THE NEXT FEW DAYS.



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 CONTINUE THIS MORNING ACROSS RIDGE TOPS AND
DOWN THE COLORADO RIVER VALLEY...BEFORE WEAKENING DURING THE LATE
MORNING. 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.
