The National Weather Service in Reno, Nevada issued a “special weather statement” warning of below freezing temperatures in parts of Nevada and the Sierra Nevada, due to an early winter storm that left snow at high elevations and brought in very cold air from the Gulf of Alaska.

…SUB-FREEZING TEMPERATURES AND FREEZING FOG EXPECTED IN SIERRA VALLEYS WEDNESDAY NIGHT AND THURSDAY NIGHT…
* Clearing skies will allow Thursday morning lows to drop into the 20s for many Sierra valleys. Between 4 to 8 hours of sub-freezing temperatures in the cooler valleys will be enough to harm sensitive vegetation and burst irrigation pipes. While not as cold as tonight, freezing temperatures are once again expected Thursday night. Take necessary steps to mitigate common issues that typically arise with the first hard freeze of the season.
* Areas of fog and freezing fog are expected to form in Sierra valleys from South Lake Tahoe northward tonight and again early Thursday morning. Reductions in visibility and slick roads and bridges are possible. Allow extra time if traveling through these areas during the early morning hours.
On Thursday, the NWS reported temperatures at South Lake Tahoe dipped to freezing once again, saying other areas of Nevada experienced freezing and near freezing temperatures, as well.
