Mid-summer temperatures and afternoon thunderstorms combined to make for a hot and humid forecast as Utah's work week got underway.

Temperatures Monday and Tuesday were predicted to hit the low-90s in northern Utah and flirt with 100 degrees in the southern portion of the state.

The National Weather Service issued a Flash Flood Watch for nearly half of Utah, warning that heavy rainfall could fill slot canyons and usually dry washes and inundate burn scars denuded by recent wildfires.

The advisory was in place from noon through 9 p.m. Monday for an area stretching from central Utah's Manti southwest to St. George and southeast to Moab and Blanding.

The Utah Division of Air Quality rated most of the Wasatch Front, including Weber, Salt Lake and Utah counties, as "yellow," or compromised. Box Elder, Cache, Washington, Carbon, Duchesne and Uintah counties were the only regions with "green," or health air quality.

The Intermountain Allergy & Asthma website listed mold at "high," while chenopod pollen came in at "moderate" levels. Other allergens were deemed "low" as of Monday.
