Mountain areas around the Inland Northwest and areas of the Columbia Basin could have isolated thunderstorms Wednesday afternoon and evening. Impacts include gusty winds around 45 mph, infrequent lightning, brief heavy rain, and small hail.
Tomorrow still looks to be the warmest day of the week, with Moderate HeatRisk across much of the area. Be sure to stay cool and hydrated. Moderate HeatRisk is dangerous to those who are sensitive to heat, especially those without effective cooling and/or adequate hydration. A cooling trend begins Thursday as we transition to a wetter, more active pattern heading into the weekend.
A change in the weather will arrive next weekend with cooler temperatures and increasing chances for rain showers and thunderstorms. Friday through Sunday will have the greatest chances for rain, thunderstorms, and breezy conditions each day across the Inland Northwest.
