UPDATE
UPDATED AVIATION SECTION.
KEY MESSAGES
1. A WARMING TREND WILL CONTINUE THROUGH NEXT WEEK WITH AFTERNOON
TEMPERATURES APPROACHING 10 DEGREES ABOVE AVERAGE DURING THE
WEEKEND AND EVEN WARMER NEXT WEEK.
2. DAILY AND MONTHLY RECORD HIGH MAXIMUM TEMPERATURES WILL BE
CHALLENGED NEXT WEEK.
3. STRONGER WIND GUSTS EXPECTED IN THE MOJAVE DESERT SLOPES THIS
WEEKEND. A WIND ADVISORY HAS BEEN ISSUED FOR THIS AREA FROM
THIS MORNING THROUGH EARLY SUNDAY MORNING.
DISCUSSION
THE AREA OF HIGH PRESSURE BUILDING OVER THE WESTERN US OVER THE
LAST FEW DAYS IS ERODING THIS MORNING, USHERING IN MORE ZONAL
FLOW AND MAINTAINING ABOVE-AVERAGE TEMPERATURES OVER CENTRAL
CALIFORNIA. A BUCKLING OF THE ZONAL PATTERN IS EXPECTED TO
DEVELOP A SHORTWAVE TROUGH THAT WILL PASS QUICKLY THROUGH THE
GREAT BASIN SATURDAY INTO EARLY SUNDAY. STRONGER WINDS
ASSOCIATED WITH THE TROUGH WILL CAUSE STRONGER GUSTS TO DEVELOP
IN THE MOJAVE SLOPES DURING THIS TIME FRAME, AND AS SUCH A WIND
ADVISORY HAS BEEN ISSUED.
A RETURN TO A STABLE PATTERN IS IN STORE FOR MOST OF NEXT WEEK
AS AN AREA OF HIGH PRESSURE BUILDS OVER THE DESERT SOUTHWEST
FROM THE EAST PACIFIC. THE SYSTEM WILL BRING ABOUT AN ADDITIONAL
WARMING TREND FOR CENTRAL CALIFORNIA, WITH AFTERNOON HIGHS
APPROACHING 20 DEGREES ABOVE SEASON AVERAGES. NEW DAILY HIGH
TEMPERATURE RECORDS ARE LIKELY ACROSS THE SAN JOAQUIN VALLEY,
WITH SOME AREAS LIKELY TO BREAK ALL-TIME MONTHLY RECORDS FOR
MARCH. WHILE THE HIGH IS EXPECTED TO WEAKEN AND MOVE EAST
TOWARDS THE END OF NEXT WEEK, TEMPERATURES WILL REMAIN MUCH
ABOVE SEASON AVERAGES.
AVIATION
LOCAL MVFR DUE TO FOG/MIST IN PARTS OF THE SAN JOAQUIN VALLEY,
INCLUDING AT KMER AND KMCE UNTIL 16Z SATURDAY. OTHERWISE, VFR
CONDITIONS ARE EXPECTED FOR THE NEXT 24 HOURS.
FIRE WEATHER
WARMING AIR TEMPERATURES AND STEADY DEW POINT TEMPERATURES WILL
LEAD TO A DECREASE IN MINIMUM RELATIVE HUMIDITIES, ESPECIALLY
FOR THE MOJAVE DESERT, HIGH SIERRA, AND COASTAL RANGE. THIS
WILL COINCIDE WITH A SHARP DECREASE IN 100- AND 1000-HR DEAD
FUEL MOISTURES AND AN INCREASE IN ERC IN THESE AREAS. RAPID
CURING OF FINE FUELS WILL BRING ABOUT SOME RISK FOR ISOLATED
GRASS FIRES. HOWEVER, LIVE FUEL MOISTURE REMAINS BELOW CRITICAL
THRESHOLDS AND SIGNIFICANT WILDLAND FIRE POTENTIAL REMAINS AT
LITTLE OR NO RISK.
AIR QUALITY ISSUES
NONE.
