It might be a nice reprieve after the heat waves we've had here in the Columbia Basin.

The Farmers’ Almanac 2025 extended fall forecast for the Pacific Northwest (Zone 6) calls for “unsettled; showers” particularly around late October and Halloween. We might see a damp and blustery fall here in the Tri-Cities.

September and October will be warmer and wetter than normal overall. September: Avg. temp 63° (1° above normal); 1” rain (slightly below normal). A mostly sunny month with brief cool spells and light rain early and mid-month, then turning very warm late. October: Avg. temp 57° (2° above normal); 4.5” rain (1” above normal). Expect a mix of sunny and rainy periods, with mild to warm temperatures throughout.

This combination of above-average temperatures and increased precipitation could make for a muggy, storm-prone autumn.

As you do school shopping for your kids, you might grab an extra jacket for them just in case. The Farmers Almanac isn't 100% correct, but it does have a pretty good ratio of being right after all these years.
