At long last, Utah’s interminable summer of heat is about to get a cooling dose of rain thanks to a series of thunderstorms expected to hit the region at mid-week.

The National Weather Service predicted the storms, which were forecast to settle over the region Tuesday night, would bring a chance of showers through Wednesday night. Rainfall was expected to be heaviest, however, in the state’s northwestern deserts and southwestern Utah.

Meanwhile, forecasters issued a “Red Flag” wildfire danger warning for northwestern Utah from Logan south to Milford. That advisory , to kick in at 3 p.m. as a spell of dry lighting moved through the area, was to expire at midnight.

A flash flood warning for the western half of the state, from Logan in the north running south and southwest to Delta and Manti, was allowed to expire Tuesday morning. However, the risk of isolated flooding remained of concern to public safety officials.

Air quality ratings for Wednesday were “Green,” or healthy, for Cache, Tooele, Uintah, Box Elder, Salt Lake, Davis, Utah, Washington and Weber Counties. On Tuesday, most of the state was flying a “Yellow,” or compromised, smoky air quality flag, according to the Utah Division of Environmental Quality.

Salt Lake City’s Tuesday high of 95 was expected to dip to 90 degrees on Wednesday; Ogden looked for 91 and 88, respectively; Provo 95 and 89; Logan 92 and 89; Wendover 90s both days; Duchesne 86 and 82; Cedar City 85 and 77;St. George 97 and 89; and Moab 96 and 89 degrees.
