Cooling Trend Begins on Sunday with Lingering Showers in Mountains

Expect mostly dry weather with only a slight chance (less than 25%) of isolated thunderstorms along the Washington Cascades, the Kittitas Valley, and the Wallowas . If any storms do pop up, Thye’ll likely be short-lived and won’t bring much rain. Temperatures will be slightly above normal.

Saturday:

Thunderstorm chances increase slightly (15-30%) across south-central Washington and the Wallowas . The best chance for storms will be in the afternoon and evening. Once again, these storms will be isolated, so not everyone will see rain.

Sunday:

A cooling trend begins as a stronger weather system moves in. Highs will be a few degrees cooler than Saturday, bringing temperatures closer to average. There could be some lingering showers or storms in the mountains, but overall, Sunday will be calmer than Saturday.

Monday through Friday:

The upcoming week will see temperatures moderating to at or just below normal, with breezy conditions through the Cascade Gaps. The probability of rain will increase, especially in the mountains. Expect cooler temperatures, especially on Tuesday and Wednesday, with slight chances of mountain showers throughout the week. Winds will be breezy, particularly in the usual windy spots like the Gorge and Kittitas/Yakima Valleys, but fire weather concerns remain low.
