Hot, dry weather translated to increased risk for wildfires in Utah’s southwestern quarter, where a "Red Flag" warning was in place into late Tuesday night.
The National Weather Service noted that along with daytime temperatures flirting with 100 degrees under sunny, nearly cloudless skies, humidity levels Tuesday were bone dry, ranging from just 5 to 10 percent in Utah’s Dixie.
With parching winds of 15-20 mph expected to continue through Wednesday, high desert grasslands and forests will remain at risk for potentially explosive wildfires.
Northern Utah looked for temperatures in the upper-80s on Tuesday and highs a few degrees lower on Wednesday. However, unlike the arid south, the Wasatch Front also expected afternoon thunderstorms and some rainfall, driven by strong, gusty evening winds.
The Utah Division of Air Quality predicted "yellow," or compromised breathing conditions for most regions statewide into late the midweek, though Carbon, Tooele and Cache counties earned "green," or healthy air quality grades.
The Intermountain Allergy & Asthma website’s pollen index was "very high" only for grass, with mold rated at "moderate."
