Area Forecast Discussion National Weather Service Sacramento CA 223 PM PST Sat Nov 28 2020

SYNOPSIS. Dry conditions with mild afternoons and cool nights are forecast through most of next week. Possible breezy conditions are expected around Tuesday-Wednesday.

DISCUSSION. Dry and mild with cool nighttime temperatures into Monday with patchy to areas of frost each night and generally light winds. Thermal belt locations morning lows will warm each of the next several nights. A weak system will pass through the region on Monday but other than bringing us some high clouds ahead of the front and maybe a some cumulus clouds over the mountains, precipitation looks to stay north of Shasta County. Behind the front Monday night into Tuesday north to northeast flow will set up. Winds should stay up enough over the north and westside of the valley to help warm the overnight lows. Temperatures will remain warmer than normal during the day with the north and some spots on the westside of the valley noticeably warmer than the rest of the valley. Winds do not look that strong at this time but the strongest winds will be over the north and westside of the valley and through favored passes and northeast to southwest oriented canyons and ridges for the mountains and foothills.

EXTENDED DISCUSSION (Wednesday THROUGH Saturday).

Cluster analysis is in very good agreement we are likely to have an amplified ridge over the West Coast throughout the extended forecast period. This will mean dry and quiet weather for Northern California. Forecast high temperatures are expected to be anywhere from 5 to 15 degrees above average for this time of year. It should be noted however, this high pressure pattern will also yield cool, slightly below average lows for the Valley with widespread 30s expected each morning. Locations along the thermal belts will stay a bit warmer due to the capping inversion in place. Low temperatures for those areas will be closer to climatological averages. Some of these foothill locations will actually see lows 5 to 10 degrees above average for this time of year.

AVIATION.

VFR conditions expected with generally light winds under 10 kts.

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.
