.SYNOPSIS...
Patchy AM Valley fog today, with light precipitation expected on
Wednesday. Warmer, above-normal temperatures then expected by late
week continuing into the weekend.

&&

.DISCUSSION...
Latest GOES-West satellite imagery depicts mostly clear skies with
isolated areas of fog and low stratus beginning to develop in the
Valley. HREF probabilities indicate a 50 to 70% chance of
visibilities less than a half mile along the eastern half of the
Valley early this morning. Visibilities should gradually improve
through the later morning hours. Clear, mostly sunny skies are
anticipated today as ridging builds aloft. Spring-like
temperatures return to the Valley with highs in the mid to low
60s. Moving up in the foothills and mountains, high temperatures
will be in the 50s to low 60s and low 40s to mid 50s,
respectively. Periods of breezy northerly winds are in store for
Valley and mountain locations today, with gusts to 15 mph at times
in the Valley.

Entering into the mid-week period, a quick-moving system is
forecast to bring light precipitation to portions of interior
Northern California on Wednesday. The majority of precipitation
will be along the Interstate 80 corridor and northward with
forecast amounts between 0.10 and 0.50 inches, with isolated totals
between 0.40 and 0.60 in the mountains. South of Interstate 80, a
few hundredths to trace amounts will be possible in the Valley
with between 0.10 and 0.20 in the upper foothills and mountains of
the Sierra. This system will also bring light snowfall
accumulations between 1 and 3 inches above 6000 feet, with lighter
amounts possible down to 5000-5500 feet. Current guidance
indicates most of the snowfall occurring during the afternoon and
early evening hours, which may result in some mountain travel
impacts during the Wednesday evening commute.

Ensembles predominantly favor ridging settling in aloft behind
this weak system, leading to near to slightly above-normal high
temperatures and dry weather through Friday. A few solutions show
the trough sliding further south once it moves over the Great
Basin which would introduce gusty north to east winds through the
Valley and over the mountains.

&&

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)...
Ensemble guidance remains largely in agreement on ridging aloft
amplifying through the end of the week and into the weekend
leading to dry weather and above-normal temperatures. Generally 30
to 50 percent probabilities of reaching 70 deg F throughout the
Delta, Valley, and foothills, then increase to 50 to 70 percent
probabilities for Monday and next Tuesday. While no strong signals
for wind impacts are anticipated with this pattern shift,
diurnally-driven north to east winds may be breezy at times.

&&

.AVIATION...

Areas of MVFR/IFR/LIFR conditions expected across portions of the
east side of the Valley and adjacent foothills due to fog, mist,
and/or low stratus between 12z-18z Tuesday. Otherwise, VFR
conditions prevail next 24 hours. Surface winds generally less
than 12 kts. Locally breezy southerly winds develop after 12z
Wednesday.

&&

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