Several rounds of precipitation are in store as a series of weather systems pass through today, Saturday and on Sunday. This will be mixed with a risk for thunderstorms, some mountain snow, and breezy conditions at times. The first wave passes this morning and early afternoon with an area of precipitation lifting across the Columbia Basin before exiting through north Idaho. A brief lull is expected before the second wave moves in and spreads showers from west-southwest to northeast between mid-afternoon and evening, along with the threat of thunderstorms. Some of these storm cells could provide some heavy downpours, small hail and gusty outflow winds. The threat of showers is high, but the overall chance your location may see a thunderstorm is about 15-20 percent. Wenatchee Valley weather today calls for cloudy skies with a 70% chance of rain and/or thunderstorms developing this afternoon with high temperatures near 60 degrees.
Then on Saturday, a third wave of moisture moves through between Saturday afternoon and evening with the next round of precipitation. Expect cloudy skies Saturday with a 70% chance of rain in the afternoon, highs in the mid 50’s.
A fourth weather wave moves into the region late Saturday night and into Sunday producing yet another round of precipitation, most focused along and south of Highway 2. Cloudy skies for Sunday with a 60% chance of rain and afternoon high temperatures around 60 degrees. The consecutive rounds of precipitation will bring with it the potential for some moderate rainfall amounts, averaging between a quarter to a half inch between today and Saturday night (48 hours). We will have to monitor smaller streams and creeks for any flooding and some steeper terrain could be susceptible to land or mudslides.
For Monday and most of next week, expect hit and miss showers under a moist westerly flow aloft. Partly cloudy skies Monday through Thursday with a 20-30% chance of scattered showers, afternoon highs in the upper 50’s to lower 60’s with overnight lows in the upper 30’s.
