Area Forecast Discussion
National Weather Service Sacramento CA
311 AM PDT Sat Sep 15 2018

.SYNOPSIS...
Below average temperatures continue into next week. Patchy smoke
and haze will continue, mainly over Shasta County.

&&

.DISCUSSION...
Partly cloudy skies across interior NorCal as shortwave off the
central California coast approaches. Current temperatures are a
little milder compared to 24 hours ago and range from around 40 in
the mountain valleys to the mid 50s to mid 60s across the Central
Valley.

Shortwave moves through this morning and may result in some
thicker clouds and perhaps some virga, but unlikely to see any
showers with precipitation reaching the ground as forecast
soundings show saturation above 12-13K feet. Mostly sunny skies
return this afternoon. Locally breezy conditions this afternoon.

High temperatures will remain below average into early next week
as the upper trough lingers, but will warm slightly inland Sunday
and Monday as heights/thickness rebound as the trough weakens.
Overnight lows will be chilly with patchy frost possible in the
mountain valleys.

&&

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)
Dry conditions and a gradual warming trend expected for the
second half of next week, with temperatures remaining near
seasonal normals. Look for Valley highs in the 80s to low 90s, and
60s to 80s over the mountains. North winds may develop Thursday
into Saturday.

&&

.AVIATION...
Mainly VFR conditions the next 24 hours. Local MVFR/IFR near
wildfires. West wind gusts 15-20 mph through the Delta. Locally
breezy southwest wind gusts 30 to 35 kts afternoon and evening
hours over the Sierra. Gusts 15-20 kts possible at TAF sites
after 21Z.

&&

.STO WATCHES/WARNINGS/ADVISORIES...None.
