.KEY MESSAGES...
1. Fog and low clouds will continue each night and morning across
the San Joaquin Valley into early next week. Dense fog will also
develop at times in the lower Sierra foothills, coastal ranges, and
the Grapevine.

2. A gradual warming trend will occur in the mountains and
desert until next week, as the high pressure pattern continues
over the region.

&&

.DISCUSSION...
A ridge of high pressure will strengthen and move further
inland. This will allow temperatures to rise, at least in the
mountains and desert. However, fog and stratus will persist over the
Central Valley as well as the coastal ranges, lower Sierra
foothills, and the Kern County mountains for at least the next few
days. Dense fog will continue at times tonight into Saturday along
major highways, such as Interstate 5 through the Grapevine in Kern
County and Highway 152 through Pacheco Pass. It is also possible
dense fog will occur anywhere that the stratus deck touches the
lower Sierra foothills and Tehachapi Mountains, including at
elevations around 1,500 to 2,500 feet. Otherwise, the Central Valley
may fog back up anywhere the stratus deck clears. Currently, short
term high resolution guidance shows a 40-50 percent chance of dense
fog anywhere in the Central Valley and lower chances (about 20-30
percent) towards the foothills and coastal ranges through the late
morning hours on Saturday.

This dry and stable pattern will last until next week and beyond.
The latest CPC outlooks have the Valley, the Sierra Nevada, and the
Mojave Desert under a 70 to 90 percent chance of above average
temperatures due to the persisting ridge. However, the outlooks show
a shift from a 40 to 50 percent probability of below average
precipitation to a 33 to 40 percent probability of above average
precipitation for the much of the Valley and Sierra Nevada.

.AVIATION...
IFR ceilings and visibilities are expected to prevail through
20Z Saturday before improving to MVFR. LIFR conditions will also
persist in the coastal ranges, Sierra foothills, and the Kern
County mountains due to the low stratus deck.
