Area Forecast Discussion National Weather Service Sacramento CA 238 PM PST Mon Nov 30 2020

SYNOPSIS. Persistent dry weather will continue with mostly clear skies and above average high temperatures. Breezy north to east winds are expected Tuesday into Wednesday.

DISCUSSION. Quiet weather continues today with some scattered high clouds pushing south over Northern California. Temperatures are generally mild, in the 60s across most of the Valley with 40s and 50s over the higher elevations. Light north to northwesterly flow will continue through the day.

The trough that brought us these mostly high clouds is forecast to continue to push inland to our north and east. As it does, this will cause pressure gradients to tighten as high pressure builds in over our area. Subsequently breezy north to easterly flow is expected to increase by Tuesday morning with breezy conditions continuing over the Northern Sierra Tuesday night into Wednesday morning.

Patchy morning frost will continue to be possible as this high pressure pattern remains in place. Lows in the Valley are forecast to generally be in the 30s with some areas in the San Joaquin Valley dipping below freezing.

EXTENDED DISCUSSION (Friday THROUGH Monday).

Dry and mild weather will continue under ridging over the west coast throughout the extended forecast period. There is high confidence we will likely remain dry with little day to day change for the first half of December as indicated by cluster analysis. We will continue to see above average high temperatures and cool morning lows, closer to climatology. This pattern will also continue to yield inversions that will keep the upper foothills and lower mountain regions a bit warmer than average overnight. Stay tuned as models are hinting at a pattern change some time mid month with some possible moisture returning to our area.

AVIATION.

VFR conditions with winds generally under 10 kts. MVFR possible KSAC and KMOD due to BR around 12-17 UTC. Increasing winds over Northern Sacramento Valley terminals expected after 6 UTC with gusts to 15 knots by 16 UTC.

STO WATCHES/WARNINGS/ADVISORIES. None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
