The Inland Northwest will experience another day of sunshine and dry weather as weak high pressure remains aloft. Northcentral Washington weather for today, sunny with a light breeze and afternoon high temperatures above normal into the upper 60’s to near 70 degrees.
Things change on Wednesday and Thursday as unsettled and breezy weather returns with the passage of an upper-level trough and associated cold front. Winds will increase from the south through the day Wednesday as pressure gradients tighten with winds and gusts between 15-30 mph by the afternoon. Under increasing clouds, high tomorrow will cool off into the mid to upper 50’s.
The low will track to the east Wednesday night and the trailing cold front will pass through. Breezy on Thursday with sunny skies and cooler temperatures with highs in the mid 50’s.
A short-lived shallow ridge of high pressure over the area Friday is expected to shift east allowing another trough of low pressure to swing through the region. It is expected to be stronger and more organized compared to the midweek system. Expect increasing clouds with a 50% chance of rain by Friday night with afternoon highs in the upper 50’s to near 60 degrees.
The weather system moves out of our area on Saturday but will leave behind cooler temperatures and partly cloudy skies with highs only in the lower to mid-50’s.
By late Saturday, another ridge of high pressure will begin to build into the region which will lead to a dry, warming trend through the end of the period. Under sunny skies both Sunday and Monday, afternoon highs will be in the upper 50s Sunday and will climb into the lower 60’s on Monday.
