.DISCUSSION...

...Today...

Another day of dry and mild conditions is expected today with our
morning log continuing to lift through the morning and early
afternoon hours. As of noon today, satellite imagery shows a
relatively cloud free northern and should remain that way into
the evening. We can expect our daily pattern of late evening to
morning fog to continue with hi-res forecasts showing a 50-75%
chance of visibilities lower than a half-mile in the Central
Valley, highest over the southern Sacramento and northern San
Joaquin Valleys. Highs today and tomorrow will be in the upper
50s to mid 60s in the Valley and adjacent foothills with warmest
temperatures over the northern Sacramento Valley and lower Sierra
foothills.

...The Week Ahead...

A stationary ridge continues to amplify across the West Coast
into this week bringing potential for persistent low stratus and
fog to the Valley. Areas above the stratus (upper foothills and
mountains) will see above normal temperatures and dry conditions
with cooler temperatures below as long as the stratus holds in
place in the Valley. Low daytime humidity and limited overnight
recovery will be likely in higher elevation areas where fog and
low clouds remain nonexistent as well. Increasing chances for
breezy upper foothills and mountain winds Wednesday and Thursday
with 50-80% chance of gusts 30 MPH or greater but pretty limited
by elevation with light winds below ~2000 feet. If these winds
extend into the lower Valley elevations, it may be a limiting
factor for fog and stratus development but is not forecasted at
this time. Wednesday and Thursday look to be the warmest days of
the week.

Generally VFR conditions continue through around 06z Wednesday at
TAF sites as dry weather and light winds prevail. MVFR/IFR/LIFR
conditions in BR/FG then expected to return after 06z at SCK, MOD,
and Sacramento sites, with some potential for lingering MVFR/IFR
cigs as BR/FG dissipates Wednesday morning. Breezy to gusty
downslope winds anticipated over the Sierra after 00z Wednesday.
