The upper level ridge of high pressure will become more amplified in Eastern Washington today with a low-pressure trough digging in over the eastern Pacific that will pump up the ridge over the Rocky Mountains. The overall message through this period hasn`t changed from recent forecast updates: we are still looking at a warming trend from Moses Lake, east, with near record high temperatures across that area. Wenatchee Valley weather today, partly cloudy skies with unseasonably warm temperatures with afternoon highs in the mid 50’s. Moses Lake and Ephrata will be flirting with 60 degrees today.
On Friday afternoon, a shortwave trough of low pressure will push across Northcentral Washington which will drive the ridge east of the region. Cooler air will accompany an occluded front with temperatures returning back to near normal values on Saturday, Sunday and into next week. The precipitation associated with this weather system is quite weak and will result in little accumulating precipitation across the Inland Northwest.
Friday weather calling for mostly cloudy skies, a 30% chance of early evening sprinkles with highs in the lower 50’s.
Saturday through Wednesday will be a very quiet weather pattern for Northcentral Washington with partly cloudy skies each day with afternoon high temperatures generally near normal, into the upper 40’s.
