Saturday:

The dry pattern lasts through Saturday evening.

Sunday Storm:

Snow is expected to push back into the region Sunday. The latest model runs show snow reaching Donner Pass around 5-7 AM. We could see some steadier snow Sunday morning and then more scattered Sunday afternoon before clearing out Sunday night.

We could see several inches of new snow by Sunday afternoon. Snow levels start out around 4000-4500 ft. and below 3000 ft. by Sunday evening. That is low in elevation with snow possibly accumulating on the roads over a long stretch from the foothills all the way through the Sierra to Nevada.

Even though this isn't a big storm, the cold nature with snow to low levels could cause travel headaches with slow travel and chain controls possible from below Blue Canyon all the way to the NV state line through Sunday afternoon. Conditions start to improve Sunday night, but slowly as it's cold which will make melting of the snow on the roads more difficult into Monday.

Monday - Thursday:

We will see a drier pattern again for Monday through Thursday with no weather-related travel impacts expected at this time.

Long-Range:

The pattern could become active again starting Friday. The long-range models suggest a weak system could bring some light snow to the northern Sierra. Then slightly wetter storms are possible next weekend for the 4th-5th.

We'll continue to watch the trends as we get closer with more details on potential travel impacts.
