Area Forecast Discussion National Weather Service Sacramento CA 139 PM PST Fri Dec 4 2020

SYNOPSIS. Mostly dry weather, above average high temperatures, and cool nights will continue. Slight chance of scattered showers in the mountains and northern Valley Saturday night through early Sunday. Gusty winds are possible Sunday and Monday which could lead to elevated fire weather concerns for some areas.

DISCUSSION. Visible satellite is showing mostly clear skies over interior NorCal early this afternoon other than a small band of high clouds over the north state. Mild weather continues this afternoon with temperatures similar to yesterday except the northern Sacramento Valley could see temperatures a few degrees warmer due to localized north winds.

A weak weather system is still on track to move through the area tomorrow through early Sunday. The main impacts are still forecast to remain outside of the forecast area. However, there still remains a chance precipitation along the Coastal Range Saturday night, with a scattered light shower or two possible over the northern Sacramento Valley, Shasta County mountains, and northern Sierra as the trough moves through early Sunday morning. Precipitation accumulation is forecast to be extremely light with flurries to less than an inch of snowfall for the higher elevations above 5000 to 6000 feet. This trough will also bring cooler temperatures to the northern Sacramento Valley for the weekend with temperatures around 5 to 10 degrees cooler tomorrow than today.

As the trough moves east on Sunday, ensemble guidance continues to indicate it will form into a closed low over Nevada later Sunday and then move southwest through California through Monday. This pattern will produce gusty north to east winds Sunday evening through Monday across northern California. Significant differences still remain between the models in the track and timing of the closed low which will ultimately impact how strong the winds become. Current forecast is for northerly Valley gusts up to 20 to 30 mph and north to east mountain and foothill gusts up to 25 to 40 mph, locally higher through favored gaps, canyons, and ridgetops. Gusty winds are expected to pick up Sunday, increasing Sunday night and early Monday, especially the downslope winds in the foothills. Winds will remain breezy through Monday before decreasing Monday night. These winds along with low daytime relative humidity and continued dry vegetation could result in elevated fire weather concerns during this period. -HEC

EXTENDED DISCUSSION (Tuesday THROUGH Friday). No major changes to the extended forecast. By Tuesday morning, the upper closed low will be located just west of the Baja Peninsula with broad ridging across Northern California, and calmer winds are expected. A shortwave passes over the Pacific Northwest Tuesday night into Wednesday, with another possible wave skimming across far northern California Thursday night into Friday. Any precipitation chances look to stay north of the area at this time, with the main impact being some possible offshore winds late week. Unseasonably mild high temperatures remain through Thursday, with highs anywhere from 5 to 15 degrees above normal for this time of year.

AVIATION. Generally expect VFR conditions across the Sacramento Valley over the next 24 hours. Could see some localized MVFR visibilities in the northern San Joaquin Valley near Stockton and Modesto overnight and into Saturday morning. Winds at terminals are forecast to remain below 12 knots.

STO WATCHES/WARNINGS/ADVISORIES. None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
