2. Above average temperatures continue to climb through Thursday before a major cooling trend into the weekend and next week.

3. Multiple storm systems on Friday night through Saturday and Sunday night through Tuesday bring much needed rain to the Valley and Sierra Foothills.

DISCUSSION

Above average temperatures continue today as a ridge of high pressure remains in place. Tonight, we can expect visibilities to lower due to mist but dense fog is not expected as there is a 25 percent chance or less of 1/4 mile visibility. Temperatures continue to rise through Thursday with Thursday having a 25 to 40 percent chance of 80 degrees.

Things change quickly on Friday as the first in a series of troughs begins to move in. In this first storm, we are looking at a 20 to 50 percent chance of 12 inches of snow above 7,000 feet through 4 am Saturday. A Winter Storm Watch is in effect from Friday through Tuesday morning due to the snow amounts expected. In the Valley, we are looking at a 35 to 50 percent chance of a quarter of an inch of rain in the Valley through Saturday night. The foothills are expecting a 35 to 60 percent chance of an inch or more of rain in this first system.

We get a brief reprieve on Sunday with a few showers remaining in the area. However, another trough slides in late Sunday into Monday through Tuesday morning. There is a 30 to 50 percent chance of an additional 6 inches of snow above 6,000 feet with this system. In the Valley, we are looking at a 25 to 50 percent chance of an additional quarter of an inch. The foothills can see a 15 to 30 percent chance of an inch or more of rain with this second system.

In the very long term, continues the wet pattern with a 60-70 percent chance of above average precipitation in the 6-10 day outlook and a 40-60 percent chance of above average precip in the 8-14 day outlook. Both the 6-10 and 8-14 day outlooks favor portions of the Valley in a 33 to 40 percent chance of below average temperatures which lines up with the major cooling trend.
