Foothill flakes, hard freeze predicted for Nevada County

Cold air dropping down from western Canada will bring widespread freezing temperatures to Nevada County early this week, potentially setting record lows, the National Weather Service said.

Mountain and foothill showers were being predicted into Monday, along with breezy winds. Snow could cause slick roads and travel delays, with a dusting of snow possible down to 1,000 feet.

Cold overnight temperatures were being predicted for Monday and Tuesday nights, including a possible hard freeze. The coldest temperatures are expected Monday night into Tuesday morning, with another night of freezing temperatures Tuesday night. Temperatures in the teens and single digits were possible in the mountains and mountain valleys.

Widespread frost is expected. Agricultural impacts could be significant, due to an early bloom from unusually mild weather in recent weeks. People should take steps to protect sensitive plants, and consider wrapping external pipes that may be vulnerable to freezing. The weather service advises residents to check on the elderly and make sure animals have a warm shelter.

According to the weather service, there will be widespread lows in the mid to upper 20s and with several hours of subfreezing temperatures possible.
