The jetstream is still well to our north as a high pressure ridge continues to sit over the West. This system will break down in the coming days as a cut off low moves eastward to the coastline of California. Although this area of low pressure is rather large, it will have little impacts on our weather in the coming days with the only change being a gradual cooling in afternoon highs from day to day.
Come Sunday evening, a trough will drop into the northwestern corner of the country from the North. Most of the associated precipitation will remain off to our east, but this system will bring in a blast of cold air beginning Monday. Temperatures will be knocked down significantly to below average readings, the low 60’s in the valleys and low 50’s in the Basin. This of course means snow levels will drop as well and if any showers do move into the forecast area with this system, it will be east of the Cascades.
With the jet stream sitting over the Pacific Northwest during this time period, breezy north, northeasterly winds will move in as well. This will bring an offshore wind to the Coast, meaning mostly sunny skies with warmer temperatures for early next week.
