Area Forecast Discussion
National Weather Service Sacramento CA
114 AM PDT Sun May 19 2024

.SYNOPSIS...
Seasonable temperatures will continue through the weekend and into
early next week. Mostly sunny and dry conditions with periods of
breezy winds expected through the next 7 days, strongest winds
tonight-Monday.

&&

.DISCUSSION...

Breezy onshore winds made it to the Sacramento Area tonight where
gusts to around 20-25 mph have been observed. Breezy winds will
relax over the next few hours. Latest GOES-18 Nighttime
Microphysics RGB indicates the marine low stratus deck has
remained confined to western Solano County tonight, unlikely to
push further east like the last two nights.

Synoptically, a trough currently digging into northeastern WA will
continue to dig into the Great Basin region through Monday, which
will create northwesterly flow overhead today. As this trough
phases with a closed upper-low which will be off the SoCal coast
Monday, pressure gradients across NorCal will increase tonight-
Monday, producing another breezy north wind day. Gusty north winds
will begin to materialize tonight across the northern Sacramento
Valley, bringing gusts of 20-30 mph, strongest winds are expected
after sunrise (7am) Monday continuing through the afternoon. The
NBM continues to highlight a 50-75% probability of gusts greater
than 34 knots (~40 mph) in the usual north wind prone area in the
western Sacramento Valley along the I-5 corridor. However, the
90th percentile NBM wind gusts only highlight an area of wind
gusts to 33 knots Monday. Looking at the model spread of wind
gusts, the difference between 25th and 90th is merely 5-8 knots
for much of the time frame of peak winds, which are expected
Monday morning through the evening. As such, not anticipating
widespread 40 mph gusts (Wind Advisory criteria), and winds
remaining mostly below criteria levels. Local areas of north winds
to 40 mph are still possibly though, especially between Red Bluff
and Colusa along I-5.

Per usual with north wind days, minimum afternoon RH`s will
decline, with widespread less than 15% RH values in the Sacramento
Valley Monday afternoon. Temperatures will be mild, but breezy
winds and low RH`s will lead to locally elevated fire weather
conditions Monday across the western Sacramento Valley.

Northerly flow will weaken Tuesday, allowing temperatures to
increase but winds to decrease. Tuesday appears to be the warmest
day in the next 7 days, with highs in the mid 80s to low 90s
across the Valley/Delta and upper 60s to low 80s in the
Foothills/Mountains.

Continued northwesterly flow will keep the door open for more
shortwaves to influence us through the rest of the week. By
Wednesday, a shortwave will begin to dig into WA/OR. This system
has limited moisture and will mainly bring another push of
northerly winds, some clouds, and cool off temperatures a few
degrees compared to Tuesday.

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...

Series of upper lows progged to move through the PacNW during the
extended forecast period. Associated upper troughing will extend
into NorCal. Models differ with timing, track, and strength of
lows leading to some forecast uncertainty with precipitation
potential. NBM shows some slight chance of showers over our
northern and eastern foothills/mountains Saturday afternoon
into evening. Near to slightly below normal high temperatures
expected through the extended period.

.AVIATION...

VFR conditions over interior NorCal next 24 hrs except local MVFR/IFR
possible in stratus vcnty of Delta and isolated in Sac Vly til
17z. In Central Vly, sfc wind mainly at or below 12 kts til 00z
Sat, then lcl sfc wind up to 16 kts. Vcnty Delta SWly sfc wind up
