Mother Nature scorns moderation when it comes to Utah's summer-time weather forecasts this year. If it's not scorching hot, then storms are threatening floods and mudslides.

The latter was the case Monday when the National Weather Service predicted an abrupt turn from hot, dry forecasts to slightly cooler and potentially far wetter expectations. Beginning at 11 a.m. Monday, a Flash Flood Watch was in effect through near midnight.

The advisory warned of the potential for flash floods in slot canyons and slides along fire-denuded slopes for a chunk of central, southern and western Utah ranging from near Provo and east to Duchesne and Green River and then south and west to Zion National Park and St. George to the Nevada and Arizona border.

Along the Wasatch Front, though, isolated thunderstorms and showers were expected to do little to lower temperatures expected to reach the upper-90s on Tuesday, mirroring Monday's forecast.

Southern Utahns looked for triple-digit temperatures along with scattered thunderstorms and rain storms for both days.

The stormy activity was helping keep air quality at healthy levels, though. The Utah Division of Air Quality graded all monitoring stations at "Green" for Tuesday.

The Intermountain Allergy & Asthma website warned that chenopod pollen was "very high," while mold was registering "moderate" levels.

Salt Lake City looked for a high of 95 on Tuesday, down from 97 forecast for Monday; Ogden expected 93 and 95 degrees, respectively; Provo 93 and 96; Logan 93 and 96; Wendover 92 and 95; Duchesne 85 and 88; Cedar City 89s; St. George 102 and 101; and Moab 94s both days.
