A weather pattern change begins today as a cold front passes through Northcentral Washington bringing increasing clouds, a slight chance for showers and much cooler temperatures. A wetter weather pattern will be in place through the week and continue through the weekend as several waves of moisture enter the Pacific Northwest. Expect cloudy skies in the Wenatchee Valley today with a 40% chance of showers and light north wind 12-17 mph, high temperatures this afternoon around 70 degrees. Today’s frontal passage will herald a stark weather pattern shift to a much cooler and wetter pattern for the remainder of this week. Satellite indicates a mammoth upper level trough in the Gulf of Alaska…in fact encompassing much of the eastern Pacific. During the next week, this parent trough will remain offshore…but spawn a series of offspring troughs and closed lows ejecting into the Great Basin and placing the Inland Northwest under sustained wrap-around moisture.

Partly cloudy skies early Wednesday with increasing afternoon clouds and a 60% chance of rain, highs in the upper 60’s. There is a 50% chance of rain on Thursday as well with high temperatures in the lower 70’s.

Friday and into the upcoming weekend, more of the same with mostly cloudy skies, and anywhere from a 30-50% chance of rain each day. High temperatures in the upper 60’s to lower 70’s. With dry soil conditions, it is expected that the ground will be able to absorb this influx of moisture with only minimal small stream flooding issues if at all.

Early next week will see a repeat performance of another wrap-around moisture episode with more areas of showers expected and even cooler temperatures with afternoon highs next week only reaching the mid 60’s.
