Area Forecast Discussion
National Weather Service Sacramento CA
904 AM PDT SUN MAR 27 2016

.SYNOPSIS...
A COOL WEATHER SYSTEM FROM THE NORTH MAY BRING A FEW SHOWERS
ACROSS THE NORTHERN MOUNTAINS, NORTHERN SIERRA AND FOOTHILLS AND
THE EASTERN SACRAMENTO VALLEY TODAY WITH A SLIGHT CHANCE OF
THUNDERSTORMS OVER THE VALLEY AND FOOTHILLS. THE MOUNTAIN SHOWER
THREAT CONTINUES THROUGH MID WEEK WITH MINOR SNOW IMPACTS EXPECTED
OVER THE SIERRA. DRY WITH WARMER TEMPERATURES THE END OF THE WEEK
WITH NEXT CHANCE OF PRECIPITATION EARLY NEXT WEEK.

&&

.DISCUSSION...
Low pressure system will begin to move into Northern California
today. Some showers and isolated thunderstorms will be possible
over the western slopes. Snow levels will be high today above
major pass levels so no impacts from snow are expected.

The system will deepen through the area on Monday with the central
part of the system moving over the Great Basin. Winds should
become windy during the day and we will likely have to issue a
wind advisory for the valley. This will likely be the bigger
impact to the region from this system than the showers.

Snow levels will lower down to around 2500 feet Monday morning
then rise to near 4000 feet for Tuesday. Not expecting widespread
precipitation with this system. Scattered showers mainly over the
foothills and mountains with isolated thunderstorms possible
through Monday.

The center of the low will move over Utah on Tuesday but wrap
around moisture may continue to produce some showers over the
mountains. On Wednesday high pressure will dry out the far
northern areas of the state while the Sierra from around I-80
southward may still have some lingering showers.

&&

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)

Upper level low will continue to push eastward on Thursday, ending
the chance for precipitation. Ridge of high pressure will build
into the West Coast, bringing dry weather for late week with above
normal temperatures. Models hinting that ridge may break down by
the weekend with a chance for showers returning, mainly across the
mountains, but differences remain between solutions. For now, have
added just some low chance POP to northern mountains and Sierra.
Something to watch heading forward.

.AVIATION...

VFR conditions for TAF sites next 24 hours. Scattered mountain showers with
low probability of thunderstorms after 20z will bring local
MVFR/IFR conditions across higher terrain. Winds will generally
under 10 kts on Sunday but will start to pick up after 09z Monday
with gusts up to 20 kts in the Valley.

.STO Watches/Warnings/Advisories...
