Windy weather conditions are being seen down the Okanogan Valley as the arctic air moves into the region. We are seeing gusts of 35-50 mph with some locally higher gusts. The Okanogan Valley, Highlands and Cascades north of Lake Chelan are definitely seeing the arctic air with current temps in the low teens to single digits with some localized below zero temps. Wind chills of zero to -16f are being seen. Model guidance is not doing a good job of forecasting the winds down the valley. Have put in what is occurring now and show a slow decrease. But winds will remain breezy through Tuesday with gusts up to 35 mph. The coldest wind chills will likely be seen across this region and into the Waterville Plateau. Everyone is urged to protect themselves, animals and livestock from this bitterly cold chills if outside exposed to the elements.
Expect cloudy skies across Northcentral today with west winds 5-15 mph and much colder with afternoon highs generally only in the lower 20’s with overnight lows in the upper single digits to around 10 degrees.
For Tuesday, partly cloudy and cold with afternoon high temperatures in the upper teens. The intrusion of cold air from the north continues allowing Wednesday morning low temperatures to be just as cold as those expected Tuesday morning, that is widespread lows in the single digits above and below zero.
On Wednesday, a low pressure system with a well maintained moisture feed into it has a warm trajectory of approach as it moves southwest to northeast into Northcentral Washington. There is a 60% chance of snow both Wednesday and Wednesday night with temperatures remaining cold only around 20 degrees.
Expect a slow warm-up beginning on Thursday with a 30% chance of snow both Thursday and Friday with afternoon high temperatures in the upper 20’s.
Another weather system with an associated warm front moves into the Pacific Northwest on Saturday bringing a 60% chance of snow with highs in the mid 30’s. Mostly cloudy skies to end our weekend on Sunday with afternoon high temperatures in the upper 30’s.
