Breezy north winds Thursday and Friday. Light showers possible

western Sacramento valley towards morning behind trough over the
Great Basin. Wind gusts up to 35 mph will be possible into
Friday. Cool temps the next few night with readings falling into

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)


Upper trough moves through Sunday into Monday bringing cooling,
gusty wind over higher terrain, and a threat of showers. The cold,
dry air aloft will bring snow levels down to between 1500 and
2500 ft by Monday, but not a whole bunch of snow. A couple inches
of snow may impact I-5 north of Redding.

The upper low moves overhead and into the Intermountain West
Monday and Tuesday which will translate to Valley afternoon
temperatures in the upper 40s to low 50s. Tuesday and Wednesday
mornings could see our coldest mornings of the season within the
Valley, dropping into the upper 20s and lower 30s.   JClapp

kts by Thu morning. Winds will weaken toward KSCK.   JClapp
