...Active Storm Pattern Next 7-10 Days...

Here is a broad summary of coming storms for the Sierra, Northeast
California, and Western Nevada.

* Snow: A period of snow and gusty winds, mixed with rain in
  lower elevation valleys, will bring slick roads and travel
  slowdowns Wednesday evening into the Thursday morning commute.
  Additional snow showers are possible Thursday afternoon and
  evening, mainly in the eastern Sierra and southeast of Lake
  Tahoe and Pyramid Lake. Isolated strong wind gusts are possible
  in the Eastern Sierra between Bridgeport and Bishop. Winter
  weather advisories are in effect.

* Cold: Colder temperatures are expected Thursday through
  Saturday which will be a huge change from the last several weeks
  of mild weather. Low temperatures into the teens and even
  single digits are likely Friday and Saturday mornings,
  especially in areas where there is new snowcover. These cold
  temperatures can impact vulnerable and homeless populations.
  Ensure irrigation systems that may still be running are
  winterized beforehand.

* More Snow: Confidence continues to increase in a series of cool
  winter storms Sunday-Wednesday next week that all together
  could bring large amounts of snow to the Sierra. Even Western
  Nevada valleys could see appreciable snowfall however there is
  less certainty on rain versus snow. While potential scenarios
  remain variable, it`s probably best to plan for possible
  prolonged travel disruptions during this timeframe and we
  recommend keeping a close eye on the forecast as the character
  and timing of these storms comes into better focus.
