Area Forecast Discussion National Weather Service Sacramento CA 224 PM PDT Fri Sep 25 2020

SYNOPSIS. Temperatures will warm over the weekend along and will be accompanied with drier and windier conditions. This will lead to critical fire weather conditions starting Saturday night and continuing through Monday morning. Above normal temperatures and dry conditions linger into late next week.

DISCUSSION. Another mainly clear satellite image for interior northern California this afternoon, with some high clouds sliding over the region. Satellite imagery is also picking up activity on the August Complex over in Trinity County, with patch smoke and haze being blown over into Shasta and Tehama counties. Zonal flow is forecast to linger over the area tonight, before an upper level ridge works it way over the west coast. Might get a small Delta Breeze for the southern Sacramento and northern San Joaquin counties, but it won't be as impactful as it was the last few nights. In addition to the weaker winds, high elevation clouds are expected to drift over a good portion of norCal. Expect overnight lows to be several degrees warmer tonight due to the cloud cover.

Tomorrow, the upper level ridge advances towards the west coast. This will consequently result in a pronounced warming and drying trend for the region. The wind will reverse from the present moist onshore flow to a dry, offshore north to east wind setup. While there has been some model run-to- run inconsistencies over the past few days; the most recent ensemble trends have bumped up, particularly in the European ensembles. Opted to favor the increased winds starting Saturday night and continuing through Monday morning. These conditions combined with hot and extremely dry weather will result in critical fire weather conditions. Thus, as a result, we have upgraded the Fire Weather Watch to a Red Flag Warning for most of interior northern CA from 9PM Saturday to 12PM Monday. North to east winds of 15 to 25 mph with gusts up to 40 mph will be possible for the Valley and foothills; however, locally favored gaps and canyons, such as Jarbo Gap, may see gusts up to 45 to 55 mph. Extreme caution should be taken to prevent new fire starts.

As mentioned earlier, this ridge will promote warming throughout the region. Widespread 90s will return to the Sacramento and northern San Joaquin Valleys for Sunday and Monday, at a minimum. Can't rule out the chance of some communities hitting 100 deg F. Corresponding heat risks will be in the low to moderate categories with general impacts to those sensitive to the heat. Models keep the ridge in place into the middle of the week. More details are provided in the extended portion of this discussion. // Rowe/KR

EXTENDED DISCUSSION (Tuesday THROUGH Friday).

A highly amplified ridge will bring warmer than normal temperatures and dry weather to interior NorCal next week. High temperatures will be anywhere from 8 to 15 degrees above average next week with temperatures around 100 degrees possible in the northern Sacramento Valley. Areas of moderate heat risk will be seen throughout the week in portions of the Valley and foothills which may impact any sensitive groups including outdoor workers. Extremely dry conditions are expected each day; however, winds will be lighter which will help mitigate fire weather concerns. Dry weather is likely to continue through the weekend.

AVIATION.

Mainly VFR conditions for the next 24 hours with the exception of local MVFR possible at RDD/RBL due to wildfire FU/HZ. Gusts up to 25 knots in the Delta vicinity with winds elsewhere generally below 12 knots.

STO WATCHES/WARNINGS/ADVISORIES.
