For Fort Nelson and Sikanni Chief…
A deepening arctic airmass clashing with Pacific moisture will continue to give snow to northeast BC. Snowfall accumulations of near 10 cm at Fort Nelson have been reported. The area of moisture will shift southward tonight to remain over southern sections through Thursday. Further accumulations of near 10 cm are expected near Sikanni Chief tonight and again on Thursday. In addition, northeast winds gusting to 50 km/h will result in low visibilities in blowing snow over southern sections.
For Fort St. John and Dawson Creek areas includes the Pine Pass.
A significant Pacific low pressure system moving into the BC Interior tonight will create a strong easterly flow of moist air over northeast BC. Snow will develop this evening and become heavy at times, especially near the Rockies. Total snowfall amounts of 15 to 25 cm are expected through Thursday night with up to 30 cm likely near the Rockies. In addition, strong easterly winds of 40 km/h gusting to 70 will give areas of blowing snow. The snow is not expected to ease until late Friday.
Environment Canada has issued a Winter Storm Watch for those around Fort Nelson and south to the BC Peace Region and Williston areas. Details below…
A low moving from the southern Yukon to northern BC will result in snow intensifying over the Fort Nelson region overnight as moderate northerly winds develop. Winds will strengthen as the arctic air begins to deepen and snow will spread over the Williston and Peace districts throughout the day on Wednesday. Strong northeast winds with gusts as high as 70 km/h are expected to give reduced visibilities in snow and blowing snow over this area through Wednesday night and into Thursday.
Snow and wind will ease Friday morning as the low moves off. General snowfall amounts will range from 10 to 20 cm but total snowfall amounts of 30 to 50 cm are possible along the Rocky Mountains especially over the northern Peace District and into the southwestern Fort Nelson region.
