SEASONAL TEMPERATURES CONTINUE TODAY THEN A DEEPER LAYER OF COOLER,
BELOW NORMAL TEMPERATURES PREVAIL WEDNESDAY AND THURSDAY. THE

2000 FEET AND WILL CONTINUE TO DEEPEN TO POSSIBLY MIXING OUT DURING
MID-WEEK. THIS PATTERN WILL BRING A RETURN OF GOOD OVERNIGHT
HUMIDITY RECOVERIES AND OVERNIGHT STRATUS. FRIDAY THROUGH THE
WEEKEND, WEAK RIDGING RETURNS WITH SEASONALLY WARM TEMPERATURES AND
DRIER CONDITIONS EXPECTED. BREEZY ONSHORE WINDS ANTICIPATED TO
DEVELOP WEDNESDAY INTO THURSDAY. OTHERWISE, DIURNALLY BREEZY
ONSHORE WINDS CONTINUE ACROSS MOUNTAIN GAPS/PASSES, ALONG THE
COAST, AND HIGHER ELEVATIONS THIS WEEK.
..DISCUSSION FROM SFOFWFEKA
HIGH PRESSURE BUILDING OFF THE COAST WILL BRING A WARMING AND
DRYING TREND ACROSS NORTHWEST CALIFORNIA THROUGH TODAY. LIGHTER
NORTHERLY WINDS, COMPARED TO YESTERDAY, ARE ANTICIPATED THIS
AFTERNOON. WEDNESDAY AFTERNOON OR OVERNIGHT AN UPPER LOW HAS THE
POTENTIAL TO BRING A FEW THUNDERSTORMS TO TRINITY COUNTY AND
NORTHEASTERN MENDOCINO COUNTY. THIS WILL ALSO BRING SLIGHTLY COOLER
TEMPERATURES AND HIGHER RH. A FEW THUNDERSTORMS ARE POSSIBLE IN
NORTHERN TRINITY ON THURSDAY AS WELL. WARM AND DRY WEATHER IS
