Area Forecast Discussion National Weather Service Sacramento CA 142 PM PST Sun Mar 3 2024

Synopsis
Impacts from a major winter storm continue to linger today for much of interior NorCal. A brief break between systems is expected overnight into Monday morning before the next round of precipitation arrives Monday afternoon. Periods of moderate mountain snow, light accumulations into the upper foothills, and light rain showers elsewhere are anticipated with this system. A brief period of quieter weather is then on the horizon midweek toward next weekend.

Discussion
today through Thursday.

Key points for the remainder of today through Tuesday:

*BLIZZARD CONDITIONS continue at high elevations (above 6500 feet)
along the Sierra through this evening. Periods of moderate to heavy snow at elevations above 3000 feet are expected through this afternoon into the evening. Winds have overall decreased, but stronger gusts (up to 45 mph) at pass level remain possible today.

*The next system will not be far behind, with brief break overnight into Monday morning and precipitation impacts returning by Monday afternoon. Up to 1 foot of additional snowfall will be possible above 4000 feet from late Monday through Tuesday. Winds gusting up to 40 mph late Monday into Tuesday over the Sierra may result in additional impacts as well.

*Mountain travel will continue to be extremely dangerous to impossible today, and will remain difficult at best through Tuesday night.

---------------------------------------------------------------

The upper low continues to progress across the Pacific Northwest, with the trough axis continuing to extend into NorCal. Another embedded shortwave traveling through the attendant northwesterly flow pattern aloft is beginning to move through interior NorCal.
This will bring the next push of moisture to the region through the afternoon and into the evening. Moderate to occasionally heavy snow is persisting over the Sierra ahead of this though, with isolated showers elsewhere.

Showery activity is expected to become more scattered through the afternoon with the aforementioned moisture push. While marginal, some weak instability is present (~100-250 J/kg in the Valley) and shear remains strong (30-50 kts 0-3 km and 100+ kts 0-6 km) as well this afternoon. As a result, isolated thunderstorms are again anticipated through the early evening, primarily across the Sacramento Valley and adjacent foothills locations. Given the parameter space, any storms that do develop will have the potential for brief heavy rain, gusty winds, small hail, lightning, and possible funnel clouds.

As these showers and isolated thunderstorms progress toward the Sierra, snowfall rates will increase once again along the Sierra through the evening. Heaviest snowfall (snowfall rates of 1 to 2 inches per hour) is expected to occur with this activity. As a result, up to an additional foot of snow will be possible above 4000 feet along the Sierra by Monday morning. Once this activity passes, light snow showers look to linger through Monday morning before the next round of moderate to occasionally heavy snow arrives later in the day Monday. Additionally, Monday will be off to a cool start, especially across the northern Sacramento Valley where there is a 30 to 60% chance of Monday morning low temperatures reaching 32F from Red Bluff northward.

Snow levels for this additional system look to sit around 3000 to 4000 feet Monday evening and overnight, before rising to 4000 to 5000 feet by Tuesday. With the drier air working into NorCal as the upper low moves further inland, available moisture for additional snowfall will be limited. That being said, there will be enough lift from another subtle shortwave to provide some possible moderate snowfall rates. Overall, looking at up to an additional foot of snow at pass level and up to 2 feet at highest peaks, with accumulations of 4 to 8 inches above 4000 feet through Tuesday. Another period of gusty winds is expected over the Sierra, with gusts up to 40 mph late Monday through Tuesday as well. These conditions combined with only a brief recovery period between systems may lead to compounding impacts over the Sierra.

Light mountain snow showers may linger through Wednesday as a separate closed low approaches SoCal, but overall significantly lesser impacts are anticipated. In fact, the approaching closed low will likely accelerate a warm up for interior NorCal, with high temperatures rebounding closer to normal by Wednesday afternoon.

*Mountain travel is HIGHLY discouraged while the warnings are in effect!*

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...

Drier weather expected Thursday through Friday as an upper-level ridge across the eastern Pacific shifts westward across interior NorCal. Before the ridge is overhead Friday, northwesterly flow Thursday will allow for some locally gusty north to east winds possible Thursday. Strongest winds expected across our usual north wind- prone areas in the north- central Sacramento Valley and mountain/foothills. At this time, probabilities for north wind gusts greater than 40 mph in the Valley are less than 10%, so not anticipating Wind Advisory level winds, just some noticeably breezy/gusty winds to around 20-30 mph. Given the increased heights aloft, high temperatures will trend up Thursday into Friday, becoming near normal by the end of the week. Cluster Analysis and Ensembles are advertising a short-wave trough may move through sometime next weekend, but confidence is low given the variance in strength, timing and location of the low.

AVIATION

In Central Valley, expect mainly VFR conditions, with periods of MVFR conditions with showers. Southerly winds generally less than 12-15 knots with gusts to 20-25 knots this afternoon and again tomorrow afternoon, strongest across the north/central Valley.
Over the foothills/mountains widespread MVFR/IFR with areas LIFR with any rain/snow showers, with west to southwest winds with gusts to around 25-40 knots. Snow levels around 2000-3500 feet.
