High pressure ridging in place across the West Coast is evident on the latest satellite imagery early this morning providing clear skies for nearly the entire state of Washington. Weather forecast for Northcentral Washington today should be another above normal temperature day for most locations under relatively sunny skies with afternoon highs in the mid to upper 50’s.

A cold front will push through the Pacific Northwest Tuesday bringing most of the associated precipitation to the Cascades, the Crest and parts of the eastern slopes of the mountains. This is a quick-moving warm front so we won`t see a drastic change in temperatures with this front and winds should be light to breezy. The Columbia Basin and Wenatchee Valley will see cloudy skies Tuesday with a 40% chance of showers and mild, with high temperatures in the lower to mid-50’s.

The flow aloft becomes more zonal (west to east) Wednesday behind the front where the jet stream begins to punch into British Columbia and Washington with a potent moisture fetch and windy conditions. Expect mostly cloudy skies with an afternoon west wind 10-20 mph, a 40% chance of late afternoon rain and afternoon high temperatures very mild into the lower 60’s. The strongest winds are forecast to be across the Columbia Basin where we could see some blowing dust.

For Thursday and Friday, the last of the precipitation will move across the region. Snow levels will begin dropping, but there is still uncertainty as where the transition from rain to snow will occur. Northcentral Washington can expect cloudy skies Thursday with a 60% chance of rain and cooler temperatures with highs in the upper 50’s. On Friday, strong north winds will funnel down the Okanogan valley and Columbia Basin bringing gusty conditions throughout the day and a 30% chance of showers with highs in the lower 50’s.

For the weekend, expect sunny skies and much cooler temperatures with afternoon highs only in the mid to upper 40’s.
