Ozone pollution in Utah barely reached unhealthy levels this year. The summer smog season ended Oct. 1, and the Utah Division of Air Quality reports none of its 15 sampling sites statewide exceeded the federal cap.

Kevin Seely sometimes gets lunch with his coworkers at downtown Salt Lake City taco cart that’s just a few blocks from where state air regulators monitor ozone pollution. He’s not surprised to learn regulators recorded so few smoggy days this summer, because that’s what Seely saw with his at-home pollution indicator: his four-year-old.

Most of Utah continues to struggle with drought. But an especially cool and rainy August has eased the dryness and triggered other consequences, too, including a monster tomato.

National Weather Service Meteorologist Mike Seaman’s put some numbers to the climate trends that Utahns have been living firsthand this August.

Rain and snow drenched northern Utah this weekend, bringing moisture that will make a big difference in spring and summer. 

Randy Julander works for the federal Natural Resources Conservation Service. He monitors Utah’s snowpack. He also watches water levels in Utah’s streams and reservoirs with an eye on what that means for irrigation and drinking water. Last week his office reported that snowpack was just 75 percent of normal statewide. Julander says key reservoirs were less than half full.

This week parts of Southern Utah have been hit hard with heavy rains and flash flooding. The National Weather Service has issued a flood watch today for most of Southern Utah around Dixie and Zion National Parks. These storms can be extremely dangerous, especially around slot canyons and dry washes where a flood can hit hours after rain fell miles away.

A University of Utah researcher is taking pictures of snowflakes in a way that’s never been done before and the results could help forecasters better predict the weather.

If you’ve ever seen a picture of a snowflake it probably looked a lot like the paper cut-outs made every winter by thousands of first and second graders across the country: unique, but perfectly symmetrical and flat. But according to Tim Garrett, an atmospheric science professor at the U who helped develop a new way to photograph snowflakes, that image is a lie.
