Area Forecast Discussion National Weather Service Sacramento CA 305 AM PST Wed Jan 22 2020

Synopsis. Mainly dry weather today, then a few weak weather systems bring low precipitation chances Thursday and Friday. Potentially wetter system Saturday with high snow levels.

Discussion. Mostly cloudy skies with a few areas of drizzle or light precip linger across NorCal in the wake of Tuesday's weak weather system. Temperatures remain very mild with current readings ranging from the 30s to lower 40s in the mountains to the upper 40s to mid 50s across the Central Valley.

Broad ridging over the eastern Pacific moves across the region later today through the end of the week. Satellite imagery shows extensive cloudiness off the coast with the blended TPW product showing a large area of 1.00-1.25 inch PW under the ridge to the west of NorCal. The moisture and cloud cover will help to maintain rather mild overnight low temperatures, and portions of the Central Valley may even see some highs reaching into the lower 60s the remainder of the week.

Another weaker system will bring a chance of light precipitation later Thursday into Friday before another system moves in over the weekend. The weekend system may bring a little more QPF, but will likely be another low-impact event as snow levels rise initially above 8k ft limiting snowfall accumulations on Saturday to just the highest elevations of the northern Sierra and Mt Lassen.

EXTENDED DISCUSSION (Sunday THROUGH Wednesday). Pacific frontal system pushes through Sunday with rain and mountain snow. Light to moderate precipitation looks to be in order with snow advisory amounts above 6000 feet. Upper ridging builds over NorCal early next week for drier forecast, however models continue to show some light overrunning precip continuing over northern portions of the CWA Monday into Wednesday.

AVIATION. Areas of MVFR/IFR conds ovr Intr NorCal tda. Isold LIFR in vly fog til 18z. Conds impvg this aftn into eve then areas of MVFR/IFR and LCL LIFR agn in vly fog aft 05z Thu. Sfc wnd genly blo 12 kts nxt 24 hrs.

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.
