A Flash Flood Watch was in effect for the entire state through late Wednesday night, with Utah’s slot canyons, normally dry washes, fire-denuded mountain slopes and urban areas with poor drainage all at risk.
OK, so that’s the bad news. The better news, the National Weather Service says, is that a drying southwest air flow should strengthen late Thursday, eventually driving away rain clouds as the weekend approaches.
But first, the region had to get past thunderstorms and rain showers, occasionally heavy, expected to stretch into early Thursday. Along the Wasatch Front, Thursday’s high temperatures were expected to reach the upper-80s, a few degrees cooler than Wednesday’s forecast.
Southern Utah also looked for diminished precipitation on Thursday after a wet Wednesday. Highs were to range into the upper-80s to low-90s.
The Utah Division of Air Quality rated the entire state in the "green," or healthy air quality category heading to the latter part of the work week.
The Intermountain Allergy & Asthma website listed chenopods as "very high" and mold "high," while other allergens were graded "low" on the pollen index as of Wednesday.
