.DISCUSSION...

...Today through Saturday...
Today saw our morning fog footprint reduced today with only reduced
visibilities over the northern San Joaquin Valley. This will
linger into the evening before another round of evening and
overnight fog and mist impact a similar area again with
visibilities as low as quarter-mile fog Saturday morning.

As of noon today, we have weak radar echoes over the Sierra with
increasing cloud cover from the southwest, south of Interstate 80.
This largely will be in the form of virga and not see much
accumulating precipitation reaching the ground. Latest hi-res
models show isolated showers form along the Sierra crest then
drift eastward out of our area. Otherwise, dry and seasonable
weather continues with highs in the 60s today and Saturday in the
Valley, cooler over the mountains

...Sunday onward...
As the upper level ridge breaks down and shifts eastward, a
glancing blow from a shortwave moves over northern CA Sunday
before a larger trough passage on Tuesday into midweek, bringing
along rain showers, mountain snow, breezy winds and cooler
temperatures Sunday through the middle of next week. Only minor
impacts are expected over this timeframe with amounts relatively
holding steady compared to last night. Sunday and then on Tuesday
look to have the most accumulations over a 24-hour periods with
lingering showers on Monday/Wednesday. Current convective outlooks
do bring a 5-10% chance of thunderstorms on Monday so we will
continue to monitor the thunder threat as we get closer to Sunday.

The Climate Prediction Center 8 to 14 day outlook then favors
below normal temperatures and above normal precipitation for the
February 13th through 19th timeframe, indicating that active
weather will continue through at least the middle of February.

[Sunday-Tuesday PM] Sierra Chances for 3" of Snow or More: 40-60%

[Sunday-Tuesday PM] Shasta Co. Chances for 0.50" of Rain or
More: 60-85%
