Weather 11-9-20


Weather satellite imagery shows clearing skies this morning as a weak, transient ridge of high pressure builds briefly over our area. Given this, temperatures are rather chilly this morning with twenties across much of the lower elevations. Northcentral Washington weather today expect increasing clouds throughout the day, light wind and afternoon high temperatures still unseasonably cold, only in the lower to mid-40’s. The break in dry weather will not last long though as clouds will quickly move in this afternoon and evening ahead of our next weather system. A weather disturbance originating from British Columbia will move into the Pacific Northwest Monday night and into Tuesday morning bringing a 40-50% chance of widespread light snow. While accumulations are generally expected to be light, this early morning snow will likely impact the morning commute tomorrow with possibly light snow on the roads in the Wenatchee Valley and Columbia Basin.

High temperatures Tuesday with clearing afternoon skies will generally be in the mid to maybe upper 40’s. By Tuesday at 4:00 p.m., we expect the following snowfall amounts:

*Wenatchee Valley: <1 inch

* Columbia Basin : <1 inch

* Spokane through Palouse : 1-2 inches

* CDA through Panhandle: 2-3 inches

Weather for Veterans Day Wednesday looks to be the quietest of the forecast period with mostly sunny skies, a light breeze with afternoon high temperatures in the mid to upper 40’s.

By late Thursday and into the weekend, another long-wave trough of low pressure deepens in the eastern Pacific and will send two or three weather systems inland. Going into Thursday, expect increasing clouds, a 50% chance of rain mixed snow by Thursday night and high temperatures in the lower 40’s.

A second more robust weather system moves inland Friday into Saturday morning, increasing the threat of precipitation throughout the region with the potential for some moderate precipitation amounts. Northcentral Washington will see cloudy skies Friday with a 40% chance of mainly rain showers during the day increasing to 50% by Friday night with highs in the mid 40’s.

For both Saturday and Sunday our weather forecast looks wet with a 50% chance of rain each day and afternoon highs in the mid 40’s. Snow levels throughout the period will be from 1600-2800 feet.
