.DISCUSSION...

...Today through Monday...

Mostly clear skies today, following the rain and cloudy weather we
experienced the last couple of days. Winds will steadily decrease
today, with downsloping northeast to east winds lingering in the
mountains through this evening, up to 15 to 25 mph at times. Given
the timing of the winds, cooler temperatures, and the recent
rainfall, no widespread fire weather concerns are anticipated at
this time. However, as northerly winds decrease, there is a 5 to
20% chance of fog development in the Valley overnight tonight;
highest chances in the northern San Joaquin Valley.

Ridging will keep the high temperatures in the high 60s to low
70s through Monday, with a slight downward trend beginning Monday
as a weather system passes through the area. This system will also
bring low chances for light precipitation in Shasta County,
particularly over the Coast Range and southern Cascades, as well
as breezy onshore southerly winds. Strongest winds expected over
the Sierra and southern Cascades, generally 20 to 30 mph, but up
to 40 mph over peaks. Otherwise dry weather is expected across the
remainder of interior NorCal.

...Tuesday and Beyond...

Dry weather continues through the majority of the work week, but
potential remains for unsettled weather at the end of October and
into early November. Ensemble guidance seems clear now that a low
pressure system will approach the area, but details about
precipitation amounts and impacts remain fairly uncertain this far
out. Regardless, this week will be an ideal time to clear gutters
and secure loose outdoor decorations and items in preparation for
any additional precipitation and gusty winds.
