KEY MESSAGES
1. A Dense Fog Advisory is in effect until 12 PM PST. Dense fog will develop each night and morning in the San Joaquin Valley through the weekend into next week.

2. Expect dry and warm conditions elsewhere with gusty easterly winds in the Sierra Nevada ridges and Kern County mountains at times this weekend into next week.

3. Overnight temperatures continue to be in the low 40s in the San Joaquin Valley this weekend and through next week.

DISCUSSION
Dense fog persists over much of the San Joaquin Valley this morning, although some of the southern locations have shown improvement in visibility, such as Porterville and Bakersfield.
Visibility has generally been as low as 200 feet this morning, and most sites are still below one quarter of a mile at the time of this writing. Expect partial clearing by this afternoon, and visibility at the rest the sites to show some improvement.
However, it is possible once again that fog will return by early this evening at some locations (for example, a 40-50 percent probability of visibility falling below 1/4 mile towards Reedley and Sanger after 8 PM tonight, per latest high resolution guidance). This valley fog regime will continue for the rest of the weekend and at least through the middle of the week as high pressure remains in control. In addition, warmer than average temperatures continue in the coastal ranges, Sierra Nevada, adjacent foothills, as well as the Kern County mountains and desert. Breezy conditions will also continue towards the Grapevine and the Tehachapi Mountains, with a probability of 30-40 percent for gusts above 30 mph through this evening.

Models show the ridge weakening by Friday of next week. There is a slight chance for flurries and light snow showers in the higher elevations of the Sierra Nevada, mainly towards Yosemite for Friday and Friday night. However, confidence is low regarding any breaks in this fog pattern in the valley by late next week. CPC guidance favors continued above average temperatures (at least a 40-50 percent chance for the 6-10 day outlook and increases to 70-80 percent by 8-14 days) and at least a slight tilt in the odds towards below average precipitation for both the 6-10 day and 8-14 day periods.


AVIATION
TAF sites have fallen into LIFR visibility conditions in the north valley areas and will remain until clearing near 21Z Sunday. MVFR conditions for the south valley will gradually decrease into this evening, with projections for LIFR starting at 02Z Sunday. Otherwise, VFR conditions prevail for the Sierra Nevada, Coastal Range, and in the Mojave Desert for the next 24 hours.
