…Winter Weather Late Tonight into Sunday Evening… .Snow levels will rise ahead of a front. Precipitation will begin late tonight with a wide range of snow levels, mainly above 6000 feet with the potential for terrain influences to result in trapped cold air in valleys. This wintry mix of sleet, snow, and perhaps brief, localized freezing rain has the highest probability of occurring in Klamath County early Sunday morning, around 4 AM to 7 AM PST. Snow levels will drop through the day on Sunday into Sunday evening. A significant accumulation of snow is expected above 4000 to 4500 feet with the snow level falling to around 3500 feet as snow showers taper off during Sunday evening. This system will also produce breezy to windy conditions.
