Area Forecast Discussion National Weather Service Sacramento CA 402 AM PST Sat Nov 28 2020

SYNOPSIS. Dry conditions with mild afternoons and cool nights are forecast through the weekend. Only opportunity for any sort of light precipitation will be on Monday for far northern California. Dry, mild, and possibly breezy conditions are expected around Tuesday- Wednesday.

DISCUSSION. Clear skies, dry air and much lighter winds have brought cooler temperatures to the area this morning. The Valley at 3 am was seeing temperatures in the 30s, with locations such as Modesto and Marysville already at freezing (32 F). Some rural locations could drop into the upper 20s. Expect widespread frost to develop by daybreak.

After a cool start, sunny conditions will quickly warm things up. Highs this afternoon will warm to the low to mid 60s, slightly above normal for this time of year.

A quiet pattern sets up over NorCal this weekend, with weak ridging across the area. Dry weather continues with little change in temperatures except for little more overnight wind. This should bring slightly less cold overnight temperatures, though some frost is still in the forecast.

An upper level trough approaches the Pacific Northwest on Monday. Some light rain and snow are possible over northwest Shasta County Monday afternoon. The Sacramento Valley and northern Sierra are expected to remain dry. Little change is expected for high temperatures with most Valley locations in the 60s. Tuesday will be a little warmer, with some breezy north winds developing as eastern Pacific ridging develops in the wake of the departing system. Valley wind gusts to around 20 mph are currently expected Tuesday afternoon. EK

EXTENDED DISCUSSION (Wednesday THROUGH Saturday).

GEFS and EC ensemble maintain strong ridging over NorCal for the second half of next week allowing dry weather with unseasonably mild days (around 10 degrees above average) and cool nights to persist. Depending on the proximity of downstream troughing over the Great Basin, occasionally breezy north to east winds will be possible.

AVIATION.

VFR conditions next 24 hours with generally light surface winds.

STO WATCHES/WARNINGS/ADVISORIES. None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
