Area Forecast Discussion
National Weather Service Sacramento CA

.Synopsis...
Dry weather with mild days and cool nights continues this week.
Locally breezy Tuesday into Wednesday.

&&

Other than some clouds across far northern California associated
with a weak system moving through the west coast ridge, and a few
high clouds at times, skies remain mostly clear. Conditions are
similar to 24 hours ago with generally light wind over most of the
area and cool temperatures. Current readings are mainly in the 20s
to lower 30s in the colder mountain locales, 30s across the
Central Valley, and lower to mid 40s over the milder foothill and
mountain thermal belts.

Little change to the dry pattern expected this week with mild days
and cool nights. The Central Valley will see some patchy late
night and early morning fog. Pattern amplifies beginning Tuesday
as the system deepens a trough to our east. This will result in
another round of breezy north to east wind Tuesday into Wednesday.
