General Conditions

Weather continues to be stable at Donner Summit with daytime highs around 80° and overnight lows around 50°.  There are afternoon clouds but little or no precipitation. For details, visit the Central Sierra Snow Laboratory web site (https://cssl.berkeley.edu); click on the “Weather Condition Plots” and select “week”. Webcams at Sugar Bowl (http://www.sugarbowl.com/home) and Donner Ski Ranch (http://webcams.donnerskiranch.com/) provide an up-to-the-minute view of current conditions.

Wildfire: The seasonal campfire ban went into effect on June 23.  For the rest of the summer, don’t have outdoor fires — including campfires, charcoal grills, etc.  Gas grills are OK.  Fire danger is currently rated as “high”.  There’s more information at https://www.truckeefire.org/fireban

Summer wildflowers are in full bloom, though you won’t find them all in any single place.  Hike over a range of altitudes and sun exposures, and you’ll find most.

Mosquitoes are out, especially at dawn and dusk.  Protect yourself against sun by wearing a hat and glasses; use sun block.

Sunrise/Sunset: Today’s (July 3) sunrise was at 5:39 AM; sunset will be at 8:31 PM.  Sunrise drifted later by 3 minutes compared to last week. Sunset has drifted earlier by about 1 minute. The days are getting shorter, but not by much.  The summer solstice was on June 20 when we had our longest day at the Summit (14 hours 57 minutes); today the length of day is 14:52.

Star Gazing: The Moon is at first quarter.  Evening star gazing will be challenging for a few more days as scattered moonlight overrides the faint stars in the evening.  But the Milky Way should be visible during evening hours in another week.  Look for Scorpio — it resembles an anchor — in the southeast.  The Big Dipper is easily visible to the northwest with its handle pointing toward overhead.  Follow the arc of the handle to Arcturus, the only bright star in that part of the sky.  Mars is still visible in the evening sky, but you have to know where to look — it has drifted east of Regulus, the bright star at the bottom of the inverted question mark in the constellation Leo.  Mars is now drifting along the underbelly of the lion.  The easiest planet to spot is Venus — very bright  in the east at 4-5 AM.

Forecast

Very comfortable conditions should continue for the next couple weeks.  Tomorrow (July 4th) will be colder (a high of 65°); but highs on other days will be in the 70s.  Starting a week from today (July 10) expect highs in the low 80s.  The greatest chance of precipitation in the next two weeks is 2% (on July 6).

Roads

I-80: The forecast is generally favorable for the next two weeks, but be alert to construction and lane closures.  There are at least three possible choke points eastbound — the worst between Rainbow Road and Soda Springs.  You can get onto “Old 40” at Cisco Grove and drive at a more leisurely pace along Hampshire Rocks Road and Donner Pass Road all the way to Truckee.  Plan ahead by following CalTrans road reports at https://roads.dot.ca.gov.

General: Paved secondary roads around the Summit should be open with no restrictions.  Off-highway vehicle routes (unpaved) are mostly open, but watch for pot holes, ruts, and mud.
