.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...
Overcast conditions continue to linger over the San Joaquin
Valley this morning, with foggy conditions and low visibilities
in the foothill areas where the cloud deck is interacting with
the local terrain. Clearing is less favorable today compared to
previous days due to a prominent high pressure ridge building
in from the west. This ridge will maintain the low level
temperature inversion currently in place for much of the day,
keeping the moisture trapped around one thousand feet above
ground level. With minimal clearing, fog has less potential for
tomorrow morning in the valley areas, with less than a 30
percent chance for visibilities less than a quarter mile. These
chances improve to 50 to 60 percent for the foothill areas of
the Sierra Nevada, Kern County Mountains, and the Coastal Range.

This pattern is expected to continue through the weekend as the
high pressure remains present over the region. As we move into
next week, cluster analysis expresses confidence in the high
pressure strengthening over central California. As the high
pressure builds, a warming trend will take place, especially in
the area mountains and foothills where afternoon highs will rise
well above season averages. By Wednesday, areas including (but
not limited to) Oakhurst, Tehachapi, and Three Rivers have a 50
to 60 percent probability to exceed 65 degrees, some five to ten
degrees above season average. Yosemite Valley, which averages
around 45 degrees at this time of year, has a 70 to 80 percent
probability to exceed 70 degrees Wednesday, Thursday, and Friday
of next week.

.AVIATION...
IFR ceilings and visibilities are expected to prevail through
21Z 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. IFR
conditions will return to the valley areas overnight after 06Z
Sunday.
