Area Forecast Discussion National Weather Service Sacramento CA 321 PM PST Mon Feb 24 2020

Synopsis. Dry weather with above average temperatures and locally breezy northerly winds at times this week.

Discussion. An upper level trough is digging into the Central US as upper level ridging builds into NorCal. That is bringing somewhat breezy north winds today with Valley gusts 20 to 25 mph. The winds are expected to diminish this evening but will pick back up tomorrow morning. They are not expected to be as strong as today but we still could see some gusts up to 20 mph.

A weak short wave trough will push into BC and the PacNW on Wednesday. We will remain mainly under the upper level ridge and this will have little affect on us but some high clouds are expected. Clear skies return for Thursday.

The strong upper level ridge in place will not only continue to bring our quiet weather but will bring warm temperatures for this time of year. Highs will be running 10 to 20 degrees above average and some record highs will be possible throughout the week.

-CJM

EXTENDED DISCUSSION (Friday THROUGH Monday). Record to near record high temperatures likely over interior NorCal Friday with mid to upper 70s expected in the Central Valley. Cooling then forecast over the weekend as deep upper troughing moves through. Models differ some with progression of wave but suggest some potential for light precip over the Shasta county mountains Saturday night and across mainly the eastern foothills and mountains Sunday. Overall QPF looks to be light attm. Precip chances diminish Sunday night into Monday as the trough digs into the Desert SW and upstream ridging builds over NorCal. Breezy north to east wind expected Monday.

AVIATION. VFR conditions the next 24 hours. Local northerly surface wind gusts 15-20 kts in the Valley and east winds over foothills after 06Z.

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.
