DISCUSSION
GUSTY WEST WINDS ARE ONGOING EARLY MORNING, AND WILL LIKELY PEAK BEFORE
0900, ALTHOUGH THEY'LL REMAIN BREEZY THROUGH THE DAY WITH FREQUENT GUSTS
ABOVE 25 MPH. HUMIDITY IS MUCH LOWER THAN EXPECTED THIS MORNING, HOVERING
NEAR 20%, AND WILL REMAIN FAIRLY LOW AS LONG AS THE GUSTY WINDS PERSIST.
HOWEVER, SOME GRADUAL INCREASE IN HUMIDITY IS EXPECTED THROUGH THE DAY
AS CLOUD COVER PICKS UP AND WINDS SLACKEN SLIGHTLY. SEVERAL HOURS OF
FAVORABLE SMOKE DISPERSAL CONDITIONS ARE EXPECTED BEGINNING NEAR MIDDAY.
MODERATE HUMIDITY RECOVERIES ARE EXPECTED TONIGHT (A NOTABLE IMPROVEMENT
COMPARED TO PREVIOUS NIGHTS), WITH WEST WINDS SEEING STEADY STRENGTHENING
THROUGH THE NIGHT. WEST WINDS WILL BECOME STRONG DURING THE DAY ON
WEDNESDAY, PEAKING IN THE AFTERNOON WHEN GUSTS ARE EXPECTED TO EXCEED 50
MPH. THERE WILL BE A CHANCE OF SNOW SHOWERS BEGINNING LATE AFTERNOON
AND CONTINUING THROUGH THE EVENING, WITH A FEW INCHES OF ACCUMULATION
POSSIBLE. SMOKE DISPERSAL CONDITIONS WILL BE HIGHLY FAVORABLE. HUMIDITY
VALUES WILL REMAIN ELEVATED DURING THE DAY WEDNESDAY, AND ARE NOT EXPECTED
TO FALL BELOW 40%.
