Winds have shifted and temperatures are climbing as the leading edge of a low pressure system approaches from the southeast. Check out the Sunburst temperature trace. Light snowfall should begin this afternoon and intensify later tonight. Models are showing around 1.5″ of water by tomorrow night. This equates to 15″ of medium density snow around 1,000′. We will likely see more in favored areas and at the higher elevations. Winds are from the SE and forecast to increase to 60mph on the ridgetops though tonight/tomorrow then back off to the 20’s by tomorrow evening. The peak of the storm looks to be midnight tonight. We may see some rain at sea level mid-storm and ridgetop temperatures climb to ~30F. Cold air in the teens should replace the warm air rather quickly however and by tomorrow evening snow returning to sea level.
Instability showers look to set in for Saturday and Sunday. We may squeak a few more inches out of these.
