Area Forecast Discussion National Weather Service Sacramento CA 218 PM PDT Thu Oct 1 2020

SYNOPSIS. Above normal temperatures and very dry conditions will be observed through Friday. Areas of wildfire smoke will impact interior NorCal for the next couple of days. Continued dry weather and a slight cooling trend is expected for the weekend, although temperatures remain above normal.

DISCUSSION. Visible satellite imagery reveals yet another smoky afternoon for much of central and northern California as the region's wildfires continue to burn. In addition to the smoke, temperatures will soar to near-record levels for many communities by the time the afternoon wraps up. The October 1st record high for Downtown Sacramento is 101 deg F, and we're presently forecasting a high of 100 deg F. Redding, Red Bluff, Stockton, and Modesto will all similarly be within a few degrees of their respective daily record highs. For comparison, the normal October 1st high temperature for Sacramento is 84 deg F. A Heat Advisory is in effect for the Delta region through this evening as areas of high heat risk impact communities such as Vacaville and Fairfield.

Another stat worth mentioning: today Downtown Sacramento tied the record for the most number of 90 deg F days in a calendar year, which is 110 days (first set in 1984). While 90 deg F may not be considered an extremely hot threshold for Sacramento, it is certainly a stat worth acknowledging and recognizing. Over the present climatological normal period (1981 to 2010), the mean number of 90 deg F days per year for Downtown Sacramento is around 86. Meteorological summer (June-July-August) was the hottest on record for Downtown Sacramento, and the month of September was also the hottest on record for the city.

In addition to the above normal temperatures, offshore pressure gradients will allow dry northerly to easterly winds to continue through Friday. This will continue to bring locally breezy conditions to wind-prone areas (e.g., Jarbo Gap) along with moderate to poor overnight relative humidity recoveries.

Ridge begins to weaken over the weekend and into early next week. This will allow temperatures to moderate back to the middle 90s for Saturday, and 80s to low 90s by Sunday. That said, continued wildfire smoke may prevent afternoon highs from realizing their fullest potential.

// Rowe

EXTENDED DISCUSSION (Monday THROUGH Thursday). GEFS and EC ensemble in general agreement weakening the persistent West Coast ridge and shifting it east by the middle of next week. Pattern will remain dry for NorCal with temperatures still around 10 degrees above average early in the week, returning to only slightly above average by Thursday.

AVIATION. Widespread MVFR with local IFR conditions due to wildfire smoke expected across the Central Valley next 24 hours. Surface wind gusts generally under 12 kts except local north to east winds for the northern Sierra where gusts may exceed 20kt.

STO WATCHES/WARNINGS/ADVISORIES. Heat Advisory until 8 PM PDT this evening for Carquinez Strait and Delta.
