Area Forecast Discussion National Weather Service Sacramento CA 154 PM PST Sat Dec 2 2023

Synopsis
Precipitation chances continue today through Sunday morning; latest precipitation amounts have trended up. Drying and warming trend expected early next week before shower chances return Wednesday through Friday, with the potential for accumulating mountain snow impacts late in the week.

Discussion
A shortwave moving through is bringing rain and high elevation snow showers to the area. Rain showers earlier this morning affected the southern Sacramento Valley, northern San Joaquin Valley and the Delta. A few lingering showers do continue in those areas, but more widespread this afternoon is focused mainly over Shasta County, the northern Sierra and the southern Cascades. Snow levels as shown by profilers and web cams are around 6,000 feet. Several inches of accumulating snow are possible above 7,000 feet for the rest of today into Sunday morning, with light amounts down to 6,000 feet. Chain controls and delays are possible, especially for the Sierra passes. Snow levels rise to around pass levels by mid-day Sunday, with lingering light showers mainly north of I-80 for Sunday afternoon.
This gradually diminish overnight into Monday. Tuesday looks dry except for a few stray showers over western Shasta County as upper level ridging develops.

Patchy fog is possible at times tonight through Sunday morning, mainly over the northern Sacramento Valley and over the mountains and mountain basins. Cloud cover will limit the development of widespread dense fog.

Afternoon highs Sunday will be in the upper 50s and low 60s throughout the Valley and 50s to around 60 in the foothills and mountains. Temperatures on Monday and Tuesday will warm into the low to mid 60s.

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)...
Ensemble guidance and cluster analysis indicated that a trough will move in from the eastern Pacific Ocean on Wednesday and will shift eastward across California through Friday. This will bring renewed shower and mountain snow chances to portions of interior northern California during this timeframe. The National Blend of Models (NBM) suggests a 55 to 95 percent probability of rain amounts of a quarter of an inch or greater for the Valley from Wednesday through Friday night, and a 45 to 85 percent probability for the foothills and mountains for an inch of rain or greater for the same timeframe. Best chances are from Interstate-80 northward, and over the mountains. At this time, snow levels start off relatively high, above 7,000 feet on Wednesday, but lower to around 5000 to 6500 feet Thursday, and then down to around 3500 to 4500 feet on Friday morning, lowest in Shasta County. The NBM shows a 35 to 75 percent probability of 4 inches of mountain snow Wednesday night through Friday night with the best chances at Lassen Park and in the Sierra Nevada. We will be keeping an eye on how this forecast trends over the next several days. Dry conditions are then favored to return Saturday as a period of ridging builds back in.

AVIATION
VFR/MVFR conditions are expected over the area for the next 24 hours. Isolated IFR conditions may occur as ceilings drop to below 1,000 feet in showers in northern TAF sites such as RDD and RBL this afternoon/evening. Fog may also develop tomorrow around 15Z in the Valley sites and cause isolated IFR/LIFR conditions as visibility may drop to less than 1/2SM. Winds are expected to be below 12 knots at all sites, with gusts up to 25 knots in the northern TAF sites.
