As of Thursday, December 19, 2013
OKANOGAN Snow is expected this week in the Cascades and the Okanogan Valley can expect frigid temperatures through the week.
An additional 2-4 inches of snow is expected in the North Cascades this week, but that will still leave snow depth lower than usual for this time of the year.
Since it’s still early in the season, forecasts for the winter months aren’t yet available, said Stan Janowicz of the Natural Resource Conservation Service in Okanogan.
The National Weather Service predicts a cold storm system will bring moderate to heavy snow to the higher elevations of Northeast Washington and near the Cascade passes.
Colder air is expected by mid-week throughout the region; a winter weather advisory was in effect Monday.
For the Okanogan Valley and into Ferry County, a hazardous weather outlook was issued Monday, with “much colder” air pushing into the area Monday and Tuesday, the National Weather Service said.
Wind is expected, with temperatures dipping into the teens to lower 20s during the days and temperatures dropping into the single digits during the nights.
