Forecast Discussion – As a high-pressure ridge moves eastward across the region on Tuesday, we should expect sunny and hot conditions with a calm southerly wind. Tuesday afternoon into Wednesday, a strong low over the Pacific will move inland and bring a dry cold front. The gusty winds with hot and dry weather will result in critical fire weather conditions Wednesday. The NWS office issued a Red Flag Warning for eastern WA on Wednesday. Air quality should be in the AQI-Good category for much of Tuesday and Wednesday. During wildfire season, air quality can degrade quickly if wildfire smoke impacts our area. /MC (Issued 7/7/26 9:15 AM)
