Next Weekend Outlook

Mountain areas around the Inland Northwest and areas of the Columbia Basin could have isolated thunderstorms Wednesday afternoon and evening. Impacts include gusty winds up to 30 mph, infrequent lightning, brief heavy rain, and small hail.

A critical fire weather pattern is taking shape. A Red Flag Warning is in effect Thursday for hot, dry, and windy conditions. Temperatures will warm into the 80s to low 90s with relative humidity dropping in the teens. The hot, dry conditions combined with strong west winds will increase concerns for critical fire weather conditions. Any new or ongoing grass fires will be capable of spreading rapidly.

Today 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.
