The passage of a weak weather system today will produce locally breezy conditions and a chance of high mountain showers. The Wenatchee Valley can expect partly cloudy skies today with northwest wind 10-15 mph at times with possible gusts to 20 mph.

Dry, warm weather and light winds will return Wednesday and Thursday as high-pressure remains off the coast of Washington. Expect mostly sunny skies both days with afternoon high temperatures in the lower 70’s.

A cooler and occasionally breezy weather pattern is expected to arrive Friday and persist into early next week as a broad upper level trough descends from the Gulf of Alaska. West winds in the 15 to 20 mph range with gusts of 30 mph or more appear to be a good bet on Friday and Saturday as cooler air spills across the Cascades. Friday`s temperatures are expected to be several degrees cooler than Thursday with the arrival of the initial cold front. Afternoon highs on Friday should be in the upper 60s for most of Northcentral Washington.

By Saturday, much of the Inland Northwest will experience high temperatures in the 50s to near 60 degrees as the Gulf of Alaskan trough arrives in earnest. This weather system doesn`t appear to have much moisture associated with it with just scattered showers expected over the mountains and the rising terrain of the West Plains and Palouse.

For Sunday and Monday, confidence continues to grow that next week will begin cooler than average as the upper level trough digs in over the Pacific Northwest and Western Canada. We will enjoy mostly sunny skies for Sunday and Monday with afternoon high temperatures in the lower 60’s and overnight lows in upper 30’s and lower 40’s
