National Weather Service Sacramento CA
114 PM PST Wed Jan 8 2025

.SYNOPSIS...
Breezy north to east winds this week accompanied by dry weather
and above-normal temperatures. Gusty north to east winds return by
the weekend.

&&

.DISCUSSION...
Our gusty winds this morning continue to trickle down throughout
the remainder of the morning and afternoon over the mountains.
Our forecast pattern will see little change over the next several
days with dry and breezy weather the main forecast highlights
through the extended forecast (through next Wednesday).

Ridging remains overtop Northern CA and will keep us dry with no
forecasted precipitation observed. Our next round of gusty winds
will begin on Saturday across the western portion of the Valley
and over the Northern Sierra, tapering off Sunday morning. North
to east gusts 25 to 35 MPH are forecasted with gusts up to 50 MPH
possible over the Northern Sierra. Breeziest periods of winds in
the Valley will be late Saturday morning into the afternoon and
Saturday evening and overnight for the Northern Sierra. Valley
NBM probabilities show around a 40-70% chance of gusts over 40 MPH
mainly west and along Interstate 5, north of I-80. Be sure to
exercise caution if operating a high profile vehicle or secure
outdoor items.

Temperatures warm today and tomorrow,particularly north of I-80
with Valley highs in the 60s and up to near 70 over the Northern
Sacramento Valley. 40s to mid 60s are forecasted across the
mountains to foothills respectively with highs cooling a few
degrees this weekend.

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...

Eastern Pacific ridging expected to build inland and be the
dominate synoptic feature as we enter next week. A closed low is
also expected to develop in the Great Basin region and retrograde
into SoCal by midweek. No precipitation is expected with this low
for NorCal. Gusty north to east winds will likely develop as PGF
increases over the area, however at this time the wind gusts look
to not be as strong as our recent event for NorCal. Above normal
high temperatures are expected, with upper 50s to low 60s for the
Valley and 40s and 50s for the foothills and mountains.

&&

.AVIATION...

Mainly VFR conditions over interior Northern California for the
next 24 hours except local MVFR/IFR conditions in BR for the
Northern San Joaquin and Sacramento Valleys from 05Z to 22Z
Thursday. Surface winds are mainly at or below 12 knots except
for northerlies/easterlies 15-20 knots over the foothills and
gusts up to 39 knots after 08Z Thursday over the Sierra Nevada
Mountains.
