area forecast discussion
national weather service sacramento ca
313 pm pst Sat jan 19 2019

Synopsis
Light precipitation for areas north of interstate 80 tonight.

Widespread precipitation Sunday, with hazardous mountain driving
conditions. Dry conditions Monday through the end of next week.

Discussion
Ridge has amplified northward over norcal, briefly pushing the
storm track over oregon. This has allowed clearing and warm
conditions over much of the sacramento valley with temperatures
warming into the mid upper 60's. Shasta tehama counties still
remain north of the warm front with areas of showers and mist
prevailing.

Storm track will shift south Sunday, as upper low drops south from
the eastern pacific. This will allow a strong cold front and upper
low to move through northern california Sunday into early Monday,
bringing heavy mountain snow. Snow levels will start off quite
high above 7000 feet Sunday, but fall rapidly during the late
afternoon and evening hours, down to 4500 feet Sunday night. This
will mean the heaviest snow will be at high pass level around
donner pass most of Sunday. The rapid drop in snow levels Sunday
evening is likely to cause extremely hazardous travel over the
sierra. Snow amounts of 1 to 2 feet are possible above 6000 feet
with 6 to 12 inches in the 5000-6000 foot region Sunday night.

Valley rainfall amounts will be less than last weeks storm with
amounts generally 0.25-0.50, up to an inch over the redding area.

Foothill locations may see from 1.00-2.00 inches.

Upper low will track into the great basin region Monday with
precipitation ending during day, although a few showers will
linger over the mountains. Upper high will build in Tuesday with
dry and warmer weather.

.Extended discussion (Wednesday through Saturday)
an amplified ridge across the eastern pacific will keep
conditions benign through late next week. Light winds and dry
conditions persist through Saturday, with some early morning fog
possible most mornings. Clear skies will contribute to warmer than
normal high temperatures each day, with lows generally around
climatological values. Highs in the valley each day will be in the
60s, with the upper 40s and low 50s seen at higher elevations.

The ridge looks to stay across the western CONUS through the
weekend.

Aviation
Some ifr MVFR conditions may be seen across northern california
overnight, with lower MVFR ceilings returning to the valley
tomorrow morning as another system moves across the area.

Southerly winds may gust as high as 30 knots at TAF sites.

Sto watches warnings advisories
Winter storm warning from 9 am Sunday to 4 am pst Monday for
west slope northern sierra nevada-western plumas county lassen
park.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
