KEY MESSAGES

1. Winter Storm Warning in effect for the Sierra Nevada above 7,000 ft until 5 PM Wednesday.

2. Wind Advisory for the Kern County desert this afternoon into Wednesday morning and the Mojave Desert slopes from this afternoon until Wednesday evening.

3. Lingering precipitation is expected through tomorrow afternoon as cut-off low continues through the region.

DISCUSSION

Lingering showers remain in our CWA after the very active afternoon today. These showers are expected to remain through the overnight hours and into tomorrow afternoon, but are likely to produce only very light precipitation mainly on the Sierra Nevada. Strong winds are expected to continue into tomorrow evening, as well, with the cut-off low continuing to hold influence over the region.

Looking to the rest of this week, a gradual warm up trend is expected through Friday before another, weaker, cut-off low is expected to move through the region by the weekend, mainly Saturday. This system is likely to produce precipitation mostly for the Sierra Nevada and its foothills, with precipitation in the Valley less likely so far.

AVIATION

VFR conditions are expected for the next 24 hours in the San Joaquin Valley. Lingering showers over the Sierra Nevada may cause mountain obscuring clouds through at least 18Z Wednesday.

AIR QUALITY ISSUES

None.
