Warm on Saturday; Cooler and Active Weather Next Week

Fair weather enthusiasts will have a limited window of opportunity to enjoy the outdoors early on Saturday, before the pattern changes to one better suited for those with a preference for more active conditions. Although relatively warm temperatures are likely for most areas on Saturday, increasing clouds and moisture should sweep from west to east during the day. While coastal locations may have minimal or no bright sunshine, far eastern sites like Pullman and Spokane could have some early sun, and are expected to be mainly rain-free through the daylight hours. In any case, the shower potential is anticipated to increase for Saturday night and Sunday, as cooler air begins to infiltrate the state.

Most of next week is forecast to be rather stormy, with periodic rain showers, wind, and cool afternoons. Unlike recent weeks, this pattern would seem to favor stronger westerly flow and rain shadow effects. Therefore, central Washington may be rather dry some of the time, while the mountains could see significant rain totals. In fact, some high elevation snowfall should serve as a sobering reminder that winter is not necessarily over on the Cascade peaks. Thus, it would behoove warm weather folks to take advantage of the beginning of this weekend, since the scattered 70+ degree temperatures of Saturday afternoon will be gone with the wind by next week.
