.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%.
