A shortwave will move into the area late tonight into early Thursday morning bringing with it a chance for snow before midnight for the Eastern Slopes of Cascades. Thursday morning we could see a possible wintry mix on the valley floors as snow levels dive down to 1500′; however, this should be a light dusting, if anything, and will quickly change to light rain as temperatures and snow levels increase. More isolated showers are expected into the overnight hours on Thursday. Snow levels will increase to about 2500′-3000′. Coastal and valley areas should expect rain into Friday as the basin and mountain locations will see snow. A WINTER STORM WATCH will be in effect from late Thursday into late Friday for all areas excluding the coast. Driving conditions over the passes will be impacted with snow covered roads and slick spots; winds will also pick up and could lead to blowing and drifting snow reducing visibility.

The next upper level low is slated to move in during the afternoon hours on Friday and persist through the weekend. Precipitation will be heavy at times with this system and will be a mixed bag across the forecast area, meaning rain snow and wind. The snow level is expected to jump up to around 5000′ going into Saturday which is above pass level, all areas below this will see mostly rain. By Sunday snow levels will continue to climb and the bulk of the precipitation will be concentrated over Northern California. Weather models have not come into agreement on this system and could move in faster bringing heavy rain Saturday, we’ll continue to monitor this system.

The bulk of the snow we’ll see will be Thursday and Friday with the lower snow levels. By Friday in the Cascades and Siskiyous we could pick up  12 to 18 inches of snowfall. West side valleys above 2500′ will see 2 to 4 inches,  Siskiyou County locations above 3000′ will get about 5″ to 10″, and the east side could see 4″ to 6″ of snow.

Stay tuned to Newswatch12 for the latest on this storm and what to expect through the weekend. Thanks for logging on and have a great evening!
