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.

&&
