How hot is it, Utah?

The National Weather Service (NWS) predict temperatures Tuesday along the Wasatch Front will hit 100 degrees or higher, a climatological doppelganger of Monday's forecast.

In an unusual twist, southern Utahns will be cooler than their northern counterparts. Utah's Dixie looks for highs only in the mid- to upper 90s, largely thanks to a localized system of thunderstorms and rain showers.

Overnight lows in both regions will be in the low to mid-70s, thanks to the same high pressure system that is keeping the heat above normal levels throughout the state.

Forecasters on Monday issued yet another Hazardous Weather Outlook due to those localized mountain storms and the risk they pose for flash flooding in slot canyons and normally dry washes.

Heavy rains in southwestern Iron County led to a Flood Warning from the NWS for that area as well as in northern Washington County. The warning, issued at 7:42 p.m., was expected to last until 9:30 p.m.

Meanwhile, the NWS issued a Flash Flood Warning at about 6 p.m. for Kane and Washington counties due to heavy rains in Zion National Park. The flooding was expected in the park along the north fork of the Virgin River through The Narrows, in the North Creek drainage through The Subway and in other slot canyons and dry washes. The warning was expected to last through 10 p.m.

The Utah Division of Air Quality has given its "Green," or healthy breathing rating for the entire state on Tuesday, after having rated much of the Wasatch Front in the "Yellow," or compromised air quality category on Monday.

The Intermountain Allergy & Asthma web site rated only mold and chenopods at "moderate" levels on its pollen index, with other allergens earning lows.

Thunderstorms were forecast to creep back into northern Utah by Tuesday night and linger through the rest of the week. In southern Utah, thunderstorms also were predicted to be around throughout the week.

Salt Lake City's high temperature Tuesday was to hit 101 degrees, following Monday's 102 degrees — abnormally high for this time of year, but still 2 degrees off a record; Ogden was expected to hit 98 on both days; Provo 99 and 100, respectively; Logan 97s; Wendover 100s; Duchesne 94 both days; Cedar City 87s; St. George 96 and 93; and Moab 99 and 101 degrees.
