Dangerous wind chills are expected to persist throughout the daytime hours today, especially for our mountain valleys, and along and north of Highway 50. These areas remain in a Cold Weather Advisory through 5 PM tonight, which is when our Extreme Cold Warning will go into effect across the entire area.. #cowx
Light, low water content snow is expected across the area today, with generally light accumulations. This is the type of snow that requires less of a snow shovel, and more of a leaf blower, or even just a broom! Even though snow will be light, gusty winds could lead to blowing snow, degraded visibilities, and travel impacts, especially through mountain passes. With dangerous wind chills ahead, please be sure to take extra precautions if you must travel today! #cowx
