The first of three weather systems is moving into Northcentral Washington this morning with cloudy skies and light west wind. By this afternoon expect a 60% chance of light showers throughout the area with highs today near 60 degrees.

Thursday through the upcoming weekend on Sunday, weather models remain in strong agreement for a cool and unsettled weather pattern as a pair of Pacific storm systems pass through the Inland Northwest. While parts of Western Washington could see heavy rain, precipitation Thursday through Friday will not be terribly heavy in the Wenatchee Valley with just 1-2 tenths of an inch expected. We will see cloudy skies both days and breezy conditions with west winds 10-20 mph, a 60-70% chance of light rain and afternoon high temperatures in the upper 50’s.

A more organized storm system arrives on Saturday with an area of low pressure spinning up over the Columbia Basin as a strong upper-level jet stream drives a sharp trough in from the northwest. Cloudy skies then to kick off our weekend on Saturday with a 70% chance of rain and cooler temperatures with highs in the mid 50’s. The Wenatchee Valley and Columbia Basin will also see localized windy conditions on Saturday in the 15-25 mph range.

Sunday through Tuesday, a weak ridge of high pressure briefly flops into Northcentral Washington Sunday as another wave of moisture drops in from the northwest and transports a plume of subtropical moisture inland. Expect a 50% chance of rain Sunday and Sunday night with afternoon high temperatures in the mid 50’s.

The ridge strengthens on Monday and Tuesday and even though we will still have a 30-40% chance of showers, afternoon high temperatures will warm intro the upper 50’s to near 60 degrees.
