Area Forecast Discussion National Weather Service Sacramento CA 320 AM PDT Tue Apr 7 2020

Synopsis. A few lingering showers over mainly the mountains into Thursday, otherwise dry weather with gradually milder temperatures expected through the remainder of the week.

Discussion. Deep closed low continues to move slowly south off the coast and is now centered to the southwest of the Bay Area. Radar shows light wrap-around showers to spread across the southern two thirds of the forecast area from the east and southeast. Current temperatures range from the upper 20s and 30s in the mountains, to the 40s to around 50 across the Central Valley.

The low will continue to move slowly southward today, then will wobble around SoCal during the second half of the week as ridging from the eastern Pacific attempts to build into NorCal. Wrap- around showers will continue to be possible across the far southern portion of the forecast area while sunshine returns to the north. Locally breezy north winds will be possible Wednesday across the northern Sacramento Valley, and gusty east winds across the higher elevations of the northern Sierra Nevada. Temperatures will return to average, or above average, beginning Wednesday.

EXTENDED DISCUSSION (Saturday THROUGH Tuesday). Despite the early week system still lingering over the Desert Southwest, eastern Pacific ridging will provide ample warm and dry weather in its wake. Toward the conclusion of the weekend, the mentioned ridge may retrograde slightly with flow amplifying over the Central Great Basin. Depending on the position of these synoptic features, some uptick in northerly winds may be possible on Sunday and Monday. While the forecast is currently dry, isolated showers may possible over higher elevations of the Sierra as that trough grazes the region. High temperatures will be quite warm running around 5 to 10 degrees above climatology. Widespread highs across the Valley and Delta should reach the mid/upper 70s with pockets of lower 80s into the northern Sacramento Valley. Skies will remain mostly sunny under the influence of the ridge with some additional clouds over the mountains from diurnal heating. ~BRO

AVIATION. Mainly VFR conditions with local areas of MVFR within any developing showers, particularly over the mountains. Isolated thunderstorms well south of Highway 50. Surface winds remain light and variable, generally under 10 knots.

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.
