Spokane, WA – Washington residents will battle another smoky, hazy evening before rain finally brings relief late Tuesday, September 30, along the I-90 corridor. Drivers should prepare for reduced visibility today and slick travel conditions by midweek as showers sweep into the Inland Northwest.
According to the National Weather Service in Spokane, widespread haze lingers through Monday with highs in the upper 70s. Air quality may dip into unhealthy ranges, particularly in low-lying valleys. Rain chances increase Tuesday evening, with a 50% likelihood of showers after 11 p.m. and locally heavier pockets expected near Spokane and Coeur d’Alene.
Motorists along I-90 should plan for slower commutes Tuesday night and Wednesday morning. Reduced traction on highways and possible ponding on road shoulders may impact morning school drop-offs and early work travel. Calm winds through Monday mean smoke will settle in, but light southerly flow by Tuesday afternoon will help disperse haze before rain arrives.
Residents are urged to limit outdoor activity until conditions improve and to keep windows closed. Those with respiratory conditions should monitor alerts closely. Charging phones, checking vehicle wipers, and planning alternate routes may help commuters navigate wet roads once the rain begins.
The incoming system signals a seasonal change as October arrives. After Tuesday’s haze-to-rain transition, Spokane can expect cooler highs in the 60s and overnight lows in the upper 40s.
Warnings may be updated if rain amounts trend higher. Residents should watch for new advisories through midweek.
