The National Weather Service, Spokane, says the snow of this morning will turn to rain this afternoon, and some of these showers may develop into short lived brief thunderstorms with gusty outflow winds.
A cold front passage will bring windy and gusty conditions to the exposed terrain of the Columbia Basin this afternoon and move through the metro, bringing gusts of 35 to 40 miles per hour common and potential local gusts to 50 miles per hour.
Such winds could make travel difficult, particularly for high profile vehicles, and could blow down trees and powerlines. Area residents are advised to bring in or tie down loose items that could blow around and cause property damage.
In British Columbia, snowfall with total amounts of 15 to 25 cm is expected on Highway 3 from Paulson Summit to Kootenai Pass.
A frontal system will cross the BC interior today, spreading heavy snow to parts of the southern highway passes. Heavy flurries will continue tonight as an unstable airmass will set up over the province in the wake of the front. Total snowfall accumulations of 15 to 25 centimeters are expected by Monday morning.
Snow will ease on Monday as the the system weakens.
