DISCUSSION
HEFTY WEST WINDS WILL CONTINUE OVERNIGHT WITH RATHER PERSISTENT GUSTY
CONDITIONS ANTICIPATED. THE STRONGEST WINDS WILL OCCUR NOW THROUGH 0600
TUESDAY. SUSTAINED 20-FT WINDS WILL BE IN THE 14-19 MPH RANGE MOST OF
THE NIGHT, WITH GUSTS LARGELY IN THE 32-40 MPH RANGE, BUT OCCASIONALLY
HIGHER. THERE'S A 30% CHANCE OF A FEW GUSTS ABOVE 45 MPH. AS LONG AS
WINDS REMAIN CONSISTENT, HUMIDITY WILL STRUGGLE TO CLIMB ABOVE 45%. IF
PERIODS OF SLIGHTLY CALMER CONDITIONS OCCUR, THEN BRIEFLY HIGHER
RECOVERIES CLOSER TO 60% WILL BE POSSIBLE. LOWS WILL FALL BELOW FREEZING,
AND THE WINDY CONDITIONS WILL LEAD TO LOW WIND CHILL VALUES OVERNIGHT.
THE CHANCE OF ANY SNOW SHOWERS IS VERY LOW (15%), AND IF ANY OCCUR,
ACCUMULATIONS ARE NOT EXPECTED TO EXCEED A DUSTING.
WIND SPEEDS WILL DIMINISH NOTABLY ON TUESDAY AFTER SUNRISE, ALTHOUGH
BREEZY WEST WINDS WILL LINGER THROUGH THE MORNING, WITH A CONTINUED
WEAKENING IN STRENGTH THROUGH THE AFTERNOON HOURS. EXPECT COOL BUT DRY
CONDITIONS DURING THE DAY, WITH MINIMUM AFTERNOON HUMIDITY APPROACHING
20%.
