Forecasters have backed off on the possibility of snow in most of the Inland Northwest tonight.
Arctic cold air is going to remain in force over the region through the weekend with lows in the teens and highs struggling to get to the low 30s in Spokane.
The sudden turn to cold weather is not unusual in the Inland Northwest where temperatures in mid-November can range from near zero on the cold side to the low 60s on the warm side.
A Pacific storm expected to move onshore today is moving along the Oregon-Washington border, bringing snow to south-central and southeast Washington where winter storm watches have been in effect.
Passage of the low to the south of the region will draw reinforcing arctic air southward, keeping the region in the cold zone into next week.
The snowfall may reach as far north as Rosalia where less than a half inch is possible tonight and Friday. The Silver Valley in Shoshone County has a similar forecast for light snow of less than an inch.
Closer to the incoming storm, Pullman and the Palouse region could see 3 to 6 inches of snow tonight and Friday. Highs there will be in the upper 20s with lows in the teens until Saturday night when a low of 7 degrees is expected in Pullman. A combination of clearing skies and snow cover should enhance the overnight temperature drop.
Coeur d’Alene has a 20 percent chance of snow showers tonight and Friday night with no accumulation expected and temperatures running from about 30 during the day to about 13 at night.
Sandpoint might see a dusting tonight and Friday. Northeast wind should ease off to about 10 mph. Highs will be in the upper 20s and low 30s with lows from 10 to 14 degrees.
The Colville Valley will remain sunny and cold with highs returning to the low 30s today. Lows will be in the single digits to 12 degrees.
Forecasters said the next chance for precipitation won’t arrive until the middle of next week with a low pressure area that is not expected to develop into a significant storm.
