Area Forecast Discussion National Weather Service Sacramento CA 319 AM PDT Wed Sep 30 2020

SYNOPSIS. Above normal temperatures and very dry conditions will continue through much of the week. Areas of wildfire smoke will drift over interior Norcal for the next couple of days. A slight cooling trend is expected for the weekend, although temperatures remain slightly above normal.

DISCUSSION. A strong and highly amplified 2+ height anomaly ridge with a 5 to 10 year return interval will remain stationary over the W coastal states into Old Mexico through the short-term forecast period. The "Omega Block" is locked in place over Wrn NOAM by 2 long wave trofs, one over the Ern third of NOAM, and the other near 150W. This will result in well above normal temps with max temps some 10 to 18 degrees above normal and widespread areas of moderate heat risk for this time of year. In fact, the Solano Co area may encounter high heat risk Wed/Thu as winds turn down valley and adiabatic warming effects from the Vaca Mtns result in the potential for triple digit temps there, and in the Nrn Sac Vly in the afternoons, provided dense smoke at least thins partially there.

Pressure rises today over the Pac NW will increase the Nly gradients sufficiently for periods of downslope winds, the strongest over the Srn Sac Vly and Nrn SJV today and into the evening. Then lighter Nly/NWly winds Thu and Fri. This will result in an unseasonably hot/dry subsiding air mass today and Thu over Norcal as supported by the NAEFS geopotential heights and return intervals for today and Thu, then weaker signals for Fri. In addition, humidity recovery will remain poor to moderate over the higher terrain due to a strong subsidence inversion until the weekend.

Experimental smoke forecast has not updated since yesterday so our smoke forecast is based on the moderate Nly flow developing today over Norcal. We expect to see the smoke layer spread Swd today and Thu over a good portion of our CWA. Not only will this suppress max temps in the areas of dense smoke, it will also negatively impact air quality over many areas over the next day or two. The dense smoke can limit the max temps some 10 deg or so and makes the temp forecast more problematic. Weakening of the ridge on Sat will allow for onshore flow and cooler temps for interior Norcal. JHM

EXTENDED DISCUSSION (Sunday THROUGH Wednesday).

Upper ridging shifts east into the Great Basin Sunday as meso low moves through SoCal Monday into Wednesday. Dry weather expected with high temperatures remaining around 3 to 7 degrees above normal.

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.
