General Conditions

THIS REPORT WAS ORIGINALLY POSTED ON THURSDAY, FEBRUARY 12.  IT HAS BEEN UPDATED TO INCLUDE A NEW FORECAST FROM THE CENTRAL SIERRA SNOW LAB AT 10:04 AM FEBRUARY 15.  EXPECT 4-5 FEET OF NEW SNOW BY FRIDAY.  COLD TEMPERATURES MEAN LOWER WATER CONTENT THAN NORMAL (MORE POWDER) BUT POTENTIALLY MORE AVALANCHE DANGER.

Winter weather has returned to Donner Summit.   Daytime high temperatures were around 50° a week ago; yesterday peaked at about 32°.  New snow has fallen over the past two days, and more is in the forecast.   The Central Sierra Snow Laboratory (https://cssl.berkeley.edu) reports 1.8 inches in the past 24 hours and 5.1 inches in the past 48 hours.   The CSSL season-to-date snowfall is now 127.4 inches, but that’s barely half of what we would see in a “normal” season to date (212.4 inches).  Webcams at Sugar Bowl (http://www.sugarbowl.com/home) and Donner Ski Ranch (http://webcams.donnerskiranch.com/) provide up-to-the-minute views of current conditions.

Sunrise/Sunset: Today’s (February 12) sunrise was at 6:56 AM; sunset will be at 5:35 PM.  Sunrise is 8 minutes earlier than last week, and sunset is 8 minutes later; so the days are getting longer by more than 2 minutes per day.

Star Gazing: The Moon is a crescent, visible in the east before sunrise; it will be new on Tuesday (February 17).  Evening star gazing will be good for the next 10 days.  Jupiter was at opposition on January 10, but it’s still very bright and close to overhead before midnight.  As the sky darkens immediately after sunset, you should be able to spot it 30-40° above the eastern horizon.  It’s the first star-like object to appear and is the brightest object in the evening sky.  At about 10 PM Jupiter is close to overhead.  Use the “pointers” in the Big Dipper to find the North Star.  Then draw a line from the North Star through Jupiter to Sirius (the “Dog Star”) toward the south.  The line is almost straight.
