The western United States is currently experiencing a prolonged period of elevated temperatures, with the Intermountain West and the broader western region continuing to see warmer-than-average conditions. A strong, persistent high-pressure ridge is the primary driver behind this ongoing heat. The Pacific Northwest is bracing for a multi-day heat wave, with daytime highs potentially soaring above 100°F (37.8°C) from northern Oregon to eastern Washington. These temperatures are expected to challenge existing records and pose significant risks to public health and infrastructure.
