What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Sacramento, CA wrote its last area forecast discussion before this red flag warning went out at Oct 13, 4:33 AM PDT, 5 hours 22 minutes earlier.

Area forecast discussion, Oct 13, 4:33 AM PDT, 5 hours 22 minutes before
Area Forecast Discussion
National Weather Service Sacramento CA
433 AM PDT Sat Oct 13 2018

.SYNOPSIS...
Breezy to gusty wind with lowering humidity will lead to
increasing fire weather concerns this weekend into Monday. Dry
with high temperatures above normal through next week.

&&

.DISCUSSION...
Satellite imagery and model analysis indicate dry NE flow aloft
between upper ridging over the eastern Pacific and a closed low
off the SoCal coast. Dry weather will prevail today, with daytime
temperatures today will be 5 to 9 degrees above normal.

Main concern during the short term period is the increasing north
to east wind this weekend, and the associated fire weather
concerns. A surface high pressure will build into the Great
Basin, leading to an enhanced surface pressure gradient. Breezy
winds will develop this afternoon, mainly from around Chico
northward. Winds will become more widespread Saturday night into
Monday morning as pressure gradient increases. The strongest winds
are expected along the western side of the Sacramento Valley, the
Sierra foothills, and portions of the Coastal Range. Latest
guidance suggests that wind speeds could approach wind advisory
criteria.

The combination of gusty winds and low humidity will likely lead
to critical fire weather conditions. Thus, a Fire Weather Watch
remains in effect from Saturday night into Monday morning. Winds
will decrease slowly by Monday afternoon as pressure gradient
relaxes.

Dry conditions and above normal temperatures will continue through
early next week, as upper ridging remains in control. Forecast highs
will be in the 80s across the Valley, with 60s and 70s over the
foothills and mountains.

&&

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)

Upper ridging from the eastern Pacific extends inland along the
West Coast next week with dry conditions continuing for interior
NorCal. Highs will be about 5-10 degrees above average with 80s
in the Central Valley and generally 60s to 70s for the mountains.
