Freezing temperatures are expected to linger into mid-week, before a modest warming trend in Northern California.
The cold snap that has threatened citrus and frosted lawns is still in place Tuesday. The frigid weather is caused by a persistent jet stream out of Canada that is pushing dry Arctic air across much of the United States.
The National Weather Service notes that Tuesday morning is a mix of temperatures. While much of the Sacramento-San Joaquin Valley is running several degrees cooler than 24-hours ago, due to lighter winds, temperatures in the foothills and mountains are much warmer.
The low on Monday was 25 degrees in Sacramento, a little above the record cold set in 1932 of 23 degrees. Tuesday morning’s unofficial low is 27 degrees in Sacramento.
The detailed, 7-day forecast for the Sacramento region from the NWS:
Monday: Sunny, with a high near 60.
