Area Forecast Discussion National Weather Service Sacramento CA 330 AM PST Sun Jan 19 2020

SYNOPSIS. Some fog possible in portions of the Central Valley and mountain valleys this morning. Mostly dry and mild today with precipitation returning late Monday into Wednesday.

DISCUSSION. Upper ridging near 120W this morning with considerable amounts of baroclinic cirrus feeding into it from approaching mid latitude wave. Despite higher clouds, some fog has developed overnight in portions of the Northern San Joaquin Valley. Potential for patchy fog to further develop north into the Southern Sac Valley and Delta overnight. Fog lifted into stratus deck yesterday in the Northern San Joaquin Valley. This likely to occur again today and will be slow to dissipate, if at all, under abundant higher cloud cover. Rising 1000-500mb thicknesses will lead to slightly warmer temperatures today for most areas in the CWA with highs near to slightly above normal.

Second mid-latitude wave approaches Monday but weakens and gets drawn into progressing long wave. Associated baroclinic zone weakens as it approaches the coast. A stronger Pacific frontal system follows quickly behind it and begins to spread associated precip into the Coastal range and northern portions of the CWA Monday night. Surface winds increase Monday night as front draws closer. Widespread precip then spreads over interior NorCal Tuesday morning as frontal system moves inland. Snow begins in the mountains of Western Plumas and Northern Sierra Nevada Tuesday morning. Bulk of associated precip moves through during the day Tuesday. Post-frontal showers Tuesday night into Wednesday can be expected, especially over our eastern mountains. Snow levels start out around 4000 to 5500 Monday night, lowering to 3500 to 4500 feet by Wednesday morning. Model QPF has decreased some from previous runs and suggests snowfall amounts of 4-12 inches generally AOA 5000 feet with locally higher amounts over Lassen Peak. Rainfall amounts in the Central Valley range from under a tenth in the Northern San Joaquin Valley to above half an inch in the Northern Sacrament Valley. Around an inch of rain is expected in the wetter foothills locations. Breezy Tuesday as the front moves through with locally windy conditions over higher terrain.

Precip turns showery Tuesday afternoon into evening with fropa. Lingering showers possible overnight into Wednesday morning, mainly over the mountains. Drier weather expected midweek with warming temperatures as upper ridging returns. Weak waves moving through the ridge will keep a slight chance of light showers over the Coastal and Shasta mountain Wed/Thu, otherwise dry with some night/morning valley fog likely.

PCH

EXTENDED DISCUSSION (Thursday THROUGH Sunday). The beginning of the forecast period will start out dry, under upper level ridging. The exception will be some light showers, mainly over the northern mountains. Forecast highs in the Valley will be in the upper 50s to low 60s, with mountain locations in the mid 30s to low 50s. Uncertainty arises late in the period as model guidance suggests the potential for widespread precipitation next weekend, but confidence is low given model disagreement. Specific details will likely change so stay tuned.

AVIATION. VFR conditions next 24 hours, except for periods of MVFR conditions, locally IFR/LIFR, mainly south of KMYV through 18z-20z today due to BR/FG.

STO WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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.
