.PREV DISCUSSION... /ISSUED 0104 AM CST Fri Nov 16 2018/
Quasi-zonal flow will remain over most of the CONUS on Saturday as
strong mid/upper-level flow will stretch from the Rockies eastward
through the Northeast. An upper-level shortwave trough will continue
sliding southeast over the Rockies/High Plains helping push a cold
front through much of the Intermountain West. This will bring
surface high pressure into the Great Basin and with a weak thermally
induced pressure trough still along the California coast,
offshore/northeasterly flow will develop across much of California,
especially across northern California.
...Western Foothills of the Sierra Nevada...
Elevated fire weather conditions will likely develop across western
portions of the Sierra Nevada into the eastern Sacramento Valley. RH
values of 12-25% and northeasterly winds of 12-20 mph with gusts of
30-35 mph are expected to develop with Saturday evening through
overnight favored for the strongest winds/lowest RH. Additionally,
Saturday morning may begin with locally elevated conditions. The
elevated area does include the Camp Fire, and IMETs have reported
isolated wind gusts up to 30 mph with weaker surface pressure
gradients during the past couple of days. Fuels remain very dry
across this area, and fire growth is expected on any existing/new
