By late morning, temperatures in Boise had barely climbed into the teens.
The National Weather Service office in Boise reports that a scant 8 degrees were registered at the Boise Airport at 8 a.m., the coldest official temperature in more than two years. But we're still far from the record low for this date: 6 below zero on Jan. 3, 1919.
The forecast calls for more of the same: partly sunny days and partly cloudy nights, with highs near freezing for the next four days, and overnight lows hovering near 20 degrees.
Meanwhile, a high-pressure system is holding eastern Idaho in its grip. Wind chills ranged from -20 to -40 degrees this morning across the Sawtooth Mountains, Caribou Highlands and the Wood River Region.
Patchy dense fog is reported in a number of eastern Idaho valleys while wind chills will keep the highlands particularly frigid.
