Area Forecast Discussion National Weather Service Sacramento CA 218 AM PST Sun Feb 23 2020

Synopsis. Dry weather. A slight cool down today then a return to well above normal temperatures next week.

Discussion. Satellite indicates the upper low was located near the Four Corners region early this morning with clear skies across northern California in its wake. Some stratus has begun to form on the western side of the Sacramento Valley, with any low cloud cover expected to dissipate by late morning. Slightly cooler temperatures will be seen across the area today behind the aforementioned system, with Valley highs in the mid and upper 60s and temperatures in the 40s and 50s in the mountains. A trough moves across the PacNW today, although it brings little more than a few clouds to the northern portion of the CWA with any precipitation remaining north of the area.

Ridging builds back in Monday through mid-week keeping dry weather in place. Northerly Valley and easterly Sierra winds will be seen Monday and Tuesday, although winds remain not particularly strong. Warming temperatures are expected through Wednesday with temperatures as much as 10 to 15 degrees above normal by mid-week.

EXTENDED DISCUSSION (Thursday THROUGH Sunday). A ridge of high pressure will persist along the West Coast later next week, resulting in dry and mild conditions. High temps will be around 10 to 20 degrees above average for late February. Cooling will be possible by next weekend as potential pattern change develops. There are signs that the ridge may break down in early March, but confidence in any details is low at this time.

AVIATION. VFR conditions the next 24 hours except for local IFR ceilings possible in the Sacramento Area thru about 18Z. Local southerly surface wind gusts 10-15 kts until 16Z, otherwise surface winds less than 10 kts.

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.
