The tail end of the weather system form yesterday will continue to push through eastern Washington into the Rockies throughout the morning. A short lived, short wave ridge of high pressure from the south is expected to build over the Inland Northwest through the day.
For Northcentral Washington today, morning fog and low clouds with calm wind, afternoon highs in the mid to upper 30’s.
The ridge is expected to breakdown early Friday morning as a low-pressure system in the Gulf of Alaska slowly pushes a negative tilted trough through the region. There is a 30% chance of snow showers after midnight and an 80% chance of mainly snow during the morning hours Friday with scattered rain/snow showers into early afternoon. High temperatures tomorrow in the mid to upper 30’s.
A ridge of high pressure will move onto the west coast on Saturday and Sunday with patchy morning fog each day, partly to mostly cloudy skies in the afternoon with high temperatures in the mid 30’s Saturday and upper 30’s on Sunday. Monday through Wednesday, an atmospheric river returns as well as unseasonably warm temperatures with a 40-50% chance of rain each day and afternoon high temperatures in the lower 40’s on Monday and Tuesday climbing into the mid to upper 40’s on Wednesday.
