..DISCUSSION FROM SFOFWFMTR
A SUBTLE COOLING AND MOISTENING TREND IS FORECAST THROUGH THE
UPCOMING WEEKEND AS A DEEPER MARINE LAYER BECOMES BETTER
ESTABLISHED. PATCHY COASTAL DRIZZLE IS ALSO LIKELY EACH NIGHT AND
EARLY MORNING THROUGH SATURDAY MORNING. BREEZY ONSHORE WINDS
DURING THE AFTERNOON AND EVENING HOURS WILL CONTINUE AS WELL, WITH
GUSTS OF 25-35 MPH EXPECTED WITHIN THE FAVORED GAPS, PASSES, AND
VALLEYS. FOR THOSE ABOVE THE MARINE INFLUENCES, POOR TO FAIR
DAYTIME HUMIDITY RETENTION CONTINUES ABOVE 2500 FEET AND INTERIOR
CENTRAL COAST.
..DISCUSSION FROM SFOFWFEKA
AN UPPER TROUGH HAS ARRIVED TO THE WEST COAST, CONTINUING THROUGH
FRIDAY. EXPECT COOLER TEMPERATURES, HIGHER AFTERNOON RH LOWS, AND
BETTER OVERNIGHT RH RECOVERIES. WINDS WILL CONTINUE TO BE
ELEVATED DUE TO INCREASED ATMOSPHERIC MIXING. THE MARINE LAYER
CONTINUES TO DEEPEN OVERNIGHT EXTENDING FARTHER INLAND AS WELL.
THIS TROUGH INCREASES THE THUNDERSTORM RISK TO A VERY LOW 5-10%
FOR THE KLAMATH MOUNTAINS AND YOLLA BOLLAS TODAY. FRIDAY SHOWS
HIGHER CHANCES UP TO 10-15 PERCENT MAINLY FOR WESTERN SISKIYOU
COUNTY OR AREAS NEAR THE COUNTY LINE. THE STORM CHANCE IS LIKELY
TO LINGER INTO FRIDAY NIGHT FOR SISKIYOU COUNTY AND PERHAPS FAR
NORTHEAST DEL NORTE COUNTY.
