..DISCUSSION FROM SFOFWFMTR
A SLIGHT COOLING TREND WILL BEGIN TODAY, WITH THE INTERIOR AREAS
REMAINING RATHER WARM AND DRY. MORE NOTICEABLE COOLING OCCURS ON
FRIDAY AND SATURDAY AS A TROUGH ENTERS THE REGION. A DEEPER MARINE
LAYER AND MOISTENING AIR MASS WILL RESULT IN EXCELLENT OVERNIGHT
HUMIDITY RECOVERIES AND GOOD DAYTIME RETENTION ACROSS MOST OF THE
REGION. THE INCOMING TROUGH WILL ALSO CAUSE WIDESPREAD GUSTY WINDS
TONIGHT INTO SATURDAY WITH GUSTS REACHING 30 TO 40 MPH ALONG THE
COAST, AT THE RIDGELINES, AND THROUGH GAPS AND PASSES. LIGHT RAIN
AND DRIZZLE ARE POSSIBLE FRIDAY AND SATURDAY MORNINGS, PARTICULARLY
ALONG THE COAST. DRIER CONDITIONS AND A GRADUAL WARMING TREND ARE
EXPECTED TO RETURN SUNDAY.
..DISCUSSION FROM SFOFWFEKA
THE PRIMARY FIRE WEATHER FOCUS CENTERS ON THE DRASTIC PATTERN
TRANSITION UNFOLDING FRIDAY AFTERNOON THROUGH SATURDAY. WHILE
NORTHWESTERN ZONES STAND THE BEST CHANCE OF RECEIVING BENEFICIAL
MOISTURE CONTAINMENT—PRIMARILY ACROSS DEL NORTE COUNTY AND TO A
LESSER EXTENT NORTHERN HUMBOLDT COUNTY—THE DRY PASSAGE OF THE FRONT
FURTHER SOUTH ACROSS LAKE AND SOUTHERN MENDOCINO COUNTIES PRESENTS
AN ELEVATED WIND AND RH THREAT. STRONG WESTERLY WINDS GUSTING
BETWEEN 30 AND 40 MPH ACROSS SOUTHERN RIDGES ON FRIDAY AFTERNOON
WILL INTERACT WITH MINIMUM RH VALUES DROPPING INTO THE 40S. ALTHOUGH
THESE RH VALUES ARE HIGHER THAN PREVIOUS DAYS, THE SUDDEN ONSET OF
STRONG, TURBULENT WINDS BEHIND THE FRONT WARRANTS CLOSE OPERATIONAL
MONITORING FOR ANY LOCALIZED FIRE ACTIVITY. ADDITIONALLY, THE 10
PERCENT THUNDERSTORM POTENTIAL OVER NORTHEASTERN TRINITY COUNTY ON
SATURDAY AFTERNOON INTRODUCES A RISK OF DRY LIGHTNING ON THE
PERIPHERY OF THE DEEPER MOISTURE.
