Area Forecast Discussion
National Weather Service Sacramento CA
336 PM PST Tue Jan 28 2020

Dry conditions are expected the rest of this week for most areas
with mild temperatures, reaching well above average late in the
week. Precipitation chances may return late this weekend, mainly
over the mountains.


A weak cold front moving across the area today has brought some
light rain showers to the Valley, Delta and foothills. Rainfall
amounts over the past 24 hours have ranged from 0.25 to 0.80
inches over the northern Coastal Range and Shasta County, down to
a few hundredths of an inch in the Sacramento area. Some light
snow showers/flurries were reported above 6000 feet along the
I-80 and Highway 50 corridor in the Sierra.

Temperatures will remain fairly mild overnight, ranging from the
upper 20s and 30s in the mountains to the mid 40s across the
Central Valley. Some fog could develop by morning as some clearing
occurs, with the best potential in the northern San Joaquin

A ridge of high pressure builds in beginning mid-week resulting in
dry and mild conditions. Temperatures are forecast to gradually
warm for the second half of this week, reaching 10-15 degrees
above average by Friday. Northerly surface flow may be strong
enough to inhibit fog potential on the west side of the Valley and
north of I-80. EK



Strong upper ridging progged over NorCal this weekend resulting in
dry weather with above normal temperatures. High temperatures in
the Central Valley projected to be upwards of 10 to 15 degrees
above normal. Night and morning valley fog will continue to be
possible Saturday. Upper ridging progresses and flattens Sunday as
upstream short wave trough moves through Interior NorCal. This Pacific
storm looks weak with some light precipitation possible over the
mountains and mainly northern portions of the Sacramento Valley.
High amplitude ridging follows inland Monday into Tuesday for
drier weather and breezy northerly wind.


VFR conditions with light winds expected through 12Z. Patchy fog
could develop after 12z over the nrn San Joaquin Valley.
