The Pacific low has moved into the Southern Interior early this morning and is making an eastward track just north of the US border.
The low is forecast to move out of BC and into northern Montana this afternoon. The Arctic front is currently stationary just south of Revelstoke and Golden and just east of Sparwood this morning. This front will move south of the US border by this evening after the low exits the province. The precipitation will end today except some flurries will persist in the South Rockies this evening. A dry Arctic airmass will then dominate over southern BC Wednesday and Thursday with only some higher cloud expected.
The Arctic surface trough off the North Coast will move towards coast tonight as the upper flow backs to a more westerly direction.
Ultra light density snow is expected over the North Coast tonight and Wednesday as temperatures remain cold aloft. Some light snow will spread into Northern Columbias and North Rockies on Wednesday as well. The precipitation over these areas will intensify on Thursday as another wave of moisture moves in. The Arctic front will also move north of Terrace in the afternoon raising the freezing level to near
1200 metres. Meanwhile, White Pass will remain near the northern edge of the precipitation Wednesday and Thursday.
Models are similar through the period except the QPF is a little higher in the north with the Canadian model.
