It would be a good idea to celebrate Pioneer Day festivities this year armed with an umbrella.

There was about a 30 percent chance that thunderstorms would crash outdoor activities across the state starting Tuesday afternoon and into the evening hours.

A flash flood warning was in place until 2:45 p.m. Tuesday in south central Washington County from the Arizona border to the Virgin River in St. George. The National Weather Service said about 2 inches of rain had already fallen there Tuesday morning, in just an hour, prompting flash-flooding concerns. Up to a half-inch more rain may also fall.

But come Wednesday, skies were expected to clear again statewide, bringing sunny skies back.

The state's air quality was expected to be green, but rated "moderate," suggesting that unusually sensitive people consider limiting prolonged or heavy outdoor exertion Tuesday and Wednesday.

Salt Lake City looked for a high of 89 Tuesday and 91 Wednesday; Ogden expected 89 and 91, respectively; Provo 91 and 92; Logan 87 and 90; Wendover 89 and 93; Duchesne 82 and 90; Cedar City 86 and 87; St. George 100 and 102; and Moab 93 and 95 degrees.
