Area Forecast Discussion National Weather Service Sacramento CA 234 AM PDT Mon Mar 30 2020

Synopsis. Threat of showers persists across far northern California thru Tuesday, otherwise dry and milder this week. Chance of precipitation returns over the weekend.

Discussion. Mostly cloudy skies linger across the region early this morning. Radar indicates that most precipitation has retreated to far northwest California. Current temperatures are milder compared to 24 hours ago across most of the area and range from the upper 20s and 30s in the mountains to the upper 40s to mid 50s across the Central Valley.

Generally drier and milder weather is expected this week as the storm track lies to the north across the PacNW. Light warm- advection precipitation will linger across the northern half of the forecast area today (generally north of I-80), then retreat further north on Tuesday. Breezy southerly winds on tap across the Sacramento Valley today.

Dry and milder conditions forecast Wednesday and Thursday with northerly surface flow returning. Highs will return to around average by Thursday.

EXTENDED DISCUSSION (Friday THROUGH Monday). Models indicating next Pacific frontal system spreads precip into NW portions of the forecast area Friday afternoon into evening, then across most of the CWA Saturday. Deterministic models then diverge late Saturday as EC drops next offshore system into NorCal Sunday. Ensembles support this solution so POPS look to increase again Sunday into Monday as next upper low impacts the area.

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.
