Sunday December 4th Evening Weather

Rain and snow becoming more widespread tonight into tomorrow morning. Heavier snow will set up around the Mt. Shasta area making for some difficult travel for that morning commute. This storm system finally moves out tomorrow night.

Tonight: Skies will be rather cloudy tonight with areas of rain and snow becoming more widespread across Southern Oregon and Northern California. Snow levels will likely fall to below 3,000' in spots overnight, especially in Siskiyou County. We do expect more persistent and heavier snow to set up in the Mt. Shasta area tonight. Snowfall rates could be 1" per hour at times into the morning hours. This will likely make for some difficult travel conditions into your Monday morning. Lows tonight will fall into the lower to middle 30s in our westside valleys with most spots in Siskiyou County dropping just below freezing or so. The eastside will see lows down in the 20s, but some spots could see temperatures fall into the 10s. Along the coast, damp and cloudy conditions will keep temperatures up in the lower 40s for lows.

A WINTER WEATHER ADVISORY has been issued:

Where: Western Siskiyou County above 4,000'

When: Until 1 PM Monday

What: New snowfall amounts of 6-12" are expected with winds gusting up to 35 mph creating blowing snow and very low visibility. Travel will be hazardous in these areas.

A WINTER WEATHER ADVISORY has been issued:

Where: Eastern Siskiyou County above 3,000', including Mt. Shasta City, Tennant, Snowmans Summit and the Mt. Shasta Ski Park

When: Until 1 PM Monday

What: New snowfall amounts of 4-12" are expected with snow totals between 12-18" above 5,000' in elevation. Heavy snow and winds gusting up to 35 mph will create blowing snow and very low visibility. Travel will be hazardous in these areas.

Tomorrow: Rain and snow will be widespread across the region Monday morning. Travel will be difficult in the Mt. Shasta area and other higher elevations of Siskiyou County. Snow could make it down into some of the valleys Monday morning like the Shasta Valley but snow amounts won't be significant. Snow showers will be likely for the eastside with 1-3" expected for most spots. Higher snow amounts are expected for the higher terrain, including the Warner Mountains. Accumulating snow will also impact travel over the Cascades and the Siskiyous. Plan on giving yourself some additional time, but snowfall amounts won't be too significant...most spots up to a few inches for our Cascade passes. The coast and inland valleys in Southern Oregon will see on and off showers through the day. A rumble of thunder is possible near the coast. We should see rain and snow shower activity in our region wind down later in the day and into Monday evening. Highs tomorrow will be in the lower to middle 40s in our westside valleys with 30s to lower 40s in Siskiyou County. The eastside and mountains will highs only in the 30s for most spots. Along the coast, highs will be in the upper 40s to lower 50s. 

Extended: Tuesday will be dry with valley clouds and fog. We should see those low clouds decrease through the day, but some of the clouds could be quite stubborn. The coast will enjoy mostly sunny skies. Wednesday will be brighter with clearing skies for most inland areas. Temperatures for highs will fairly seasonal. 

On Thursday, a potent cold front will swing through bringing rain and snow back to our region. Precipitation will be widespread but snow levels will plummet through the afternoon and into Thursday evening night. We could see snow levels reach down to the valley floors. Expect some travel headaches later Thursday into Friday. We'll see more rounds of wet weather into this next weekend.
