textproduct: San Joaquin Valley

KEY MESSAGES

1. A Wind Advisory will be in effect through tomorrow morning in the Mojave Desert slopes with a 55 to 75% chance of gusts exceeding 40 mph in that area.

2. Below normal temperature for Wednesday before warmup into the weekend.

3. Dense Fog Advisory in effect from midnight until 10 AM Wednesday in the San Joaquin Valley.

DISCUSSION

Radar is picking up some tapering showers over the Sierra Nevada mostly north of Yosemite this evening. However, the skies will clear up and temperatures cool overnight as the quick- moving trough exits the area. However, latest model runs highlight visibilities lowering across the San Joaquin Valley mainly along the Highway 99 corridor. Therefore, we issued a Dense Fog Advisory from midnight until 10 AM for the Valley for visibilities down to 1/4 mile or less. We also have gusty winds along the Mojave Slopes and Desert overnight with a Wind Advisory until Wednesday morning.

A ridge of high pressure slides in on Wednesday bringing in benign weather with a warming trend into the weekend. However, the ridge also will bring enough stability to the area that fog could be a concern every day into the weekend. However, no precipitation is expected this weekend.

However, we are looking at a pattern change next week as a trough is looking to slide in on Tuesday. However, early probabilities show no rain until next Wednesday. The CPC, however, has a 60-70 percent chance in the 6-10 and a 50-60 percent chance in the 8-14 day outlooks for above average precipitation. Despite, this both outlooks also have strong signals of above average temperatures.

AVIATION

IFR to MVFR conditions with areas of LIFR begin to pop up around 8Z and will gradually spread south and lower through 14Z in the Valley. After 14Z, conditions slowly begin to improve until 18Z. Otherwise, VFR conditions are expected to prevail for the Sierra Nevada, West Side Hills, and Mojave Slope and Desert for the next 24 hours.
