A strong westerly flow will be over the Pacific Northwest today as one low pulls away from the area and another low-pressure weather system approaches from the Pacific. We will see drier air moving through this flow throughout the day today. The stable flow begins to buckle tonight and Saturday morning as another weather system sets up in the eastern Pacific.

By Saturday afternoon and evening, the flow will back to the southwest as that upper level low slides into western Washington. The southwesterly flow will once again tap into deeper subtropical moisture, maybe not as deep as the past weather system, but pretty close. The weather conditions for the Apple Cup on Saturday will be very wet and cool.

In the period from Saturday afternoon to Sunday night, we could see upwards of a quarter to a half inch of precipitation in the Wenatchee Valley. Temperatures will cool back to our average for late November of 40 degrees by next week with drier and breezier conditions before another round of rain heads our way by the end of next week.
