While the morning commute will not be impacted, the commute home and school buss ride home will be the problem. Then through the weekend, snow sticking to roads as well as icy roads and the potential for black ice. While temperatures will remain below freezing this weekend for inland areas through the next several days, the sun will be out and cause snow to melt and re-freeze creating hazardous conditions. Sidewalks also will be slick. Main road impacts will be: I-5, Highways: 199, 140, 66, 99, 62, 138, 97, 230, and 395.

On the backside of this storm temperatures drop even further! Single digits are expect for west side valleys, below zero for the east side and some higher elevations, with highs staying below freezing for west side valleys through Monday and in the teens and 20s for the mountains and east side. Take precautions to prevent pipes from freezing, bring pets indoors and keep outdoor livestock warm with drinkable water.
