Big thunder boom rocks Salt Lake City

• I reached out to the National Weather Service to learn what caused it.

Details: A thunderstorm moved through Salt Lake City around 3am Thursday and produced three lightning strikes, NWS meteorologist John Cecava told Axios in an email.

• The roar was likely the result of a cloud-to-cloud strike that hit near the Salt Lake City International Airport, he noted.
• "This type of lightning strike that occurred was a positive strike. Most lightning strikes are negative strikes, but the positive strikes tend to be stronger," he said.
• Positive lightning is rare and accounts for less than 5% of all strikes, per the NWS.

What to watch (and listen for): A chance of rain and thunderstorms is forecasted in Salt Lake City for most of next week.
