A slow-moving heat wave continues to expand over the Four-Corners region, supporting hot, sunny, and mostly dry conditions throughout the week and into the weekend. Today will be mostly sunny with afternoon temperatures in the upper 80s to low 90s. Dewpoints will be in the upper 20s to low 30s with precipitable water (PWAT) values around 0.50”. These conditions will encourage dry weather today, with skies becoming partly cloudy around sunset. A few isolated showers are possible along complex terrain later this afternoon and evening but are expected to dissipate before reaching the Plains.

STORM RAINFALL POTENTIAL AND DURATION: Thunderstorms today have the potential to produce up to 0.10” in 10-30 minutes.

WORST CASE SCENARIO: A strong thunderstorm may be capable of producing 0.20” or more in 30 minutes or less.

A LOOK AHEAD: The heat wave intensifies over Colorado tomorrow as afternoon highs climb into the mid to upper 90s. Skies will be sunny and clear throughout the day and overnight. Friday will be hot and sunny with temperatures soaring into triple digits across the High Plains. Very little change to this pattern is expected Saturday as the heat wave remains firmly anchored over the Intermountain West. High temperatures will once again reach a scorching 100°F. Skies will remain clear, providing no relief from the extreme heat expected with this system. Broiling continues Sunday with afternoon highs expected to exceed 100°F.
