Area Forecast Discussion National Weather Service Sacramento CA 207 PM PDT Tue Sep 22 2020

SYNOPSIS. Chance of showers over the Shasta and Coastal mountains Wednesday night and Thursday, otherwise dry weather expected. Temperatures close to average this week, then hot, dry, and potentially windy conditions return over the weekend with possible critical fire weather conditions.

DISCUSSION. Visible satellite imagery shows a band of high clouds beginning to enter far northwestern California this afternoon in advance of a system that will impact the Pacific Northwest later this week. Highs this afternoon will be in the middle 80s to around 90 deg F for the Sacramento and northern San Joaquin Valleys, or within a few degrees of where we should be for the first day of astronomical autumn. Smoke and haze from the region's wildfires will continue to impact some communities again today.

Onshore flow will persist with an evening and overnight Delta breeze bringing occasional gusts to around 30 mph in/around the Delta. This will also promote sufficient cooling with comfortable overnight temperatures for many communities for the next few nights.

Rain shower chances on Thursday will be largely limited to far northwest California. The National Blend of Models has trimmed back precipitation chances a bit for the far northern Sacramento Valley to less than 10 percent. Sacramento is expected to remain dry.

Temperatures begin to warm this weekend and into next week, along with increasing chances of critical fire weather conditions. Please refer to the extended section of the discussion for more details. // Rowe

EXTENDED DISCUSSION (Saturday THROUGH Tuesday). High pressure builds over interior Northern California over the weekend into early next week. This will result in a warming trend with above normal temperatures. Highs by Monday/Tuesday in the Central Valley will be in the upper 90s to around 102. Moderate heat risk is possible in the Valley and surrounding foothills. This heat could impact sensitive groups. Breezy north to east wind develops Saturday and continues into early Tuesday. Combination of wind, hot temperatures and low humidity will bring elevated fire weather conditions. A Fire Weather Watch is in effect from Saturday morning through Monday morning including the west side of the Sacramento Valley, the Coastal Range, the Sierra Nevada foothills and the Delta. Please practice fire safety.

AVIATION. VFR conditions over interior NorCal next 24 hrs except local MVFR conditions in HZ/FU vicinity of wildfires. Surface wind generally below 12 kts, except for local gusts up to 20-30 kts vicinity Delta. Southwest wind gusts up to 20-30 kts over higher terrain thru 03Z Tuesday, then increasing again after 18z Tuesday.

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.
