FNUS55 KSLC 230937 FWFSLC Fire Weather Planning Forecast for Utah National Weather Service Salt Lake City UT 337 AM MDT Sun Aug 23 2026 ...STORMS TODAY WITH A DRYING TREND THIS WEEK... .BROADCAST DISCUSSION...Scattered storms redevelop this afternoon across most of Utah with strong to severe storms possible across northern Utah. Precipitation will continue throughout the evening and overnight hours across northern Utah tonight. Conditions will gradually dry through the week. .DISCUSSION...Some weak showers continue across central Utah this morning. This activity will continue to decrease in coverage. Storms will redevelop this afternoon across most of Utah. There exists a slight risk of strong to severe storms across northern Utah this afternoon as storms will be capable of producing large hail and strong winds. These storms will gradually weaken late in the evening and overnight, but persist in weaker form across northern Utah, similar to what has occurred the last couple of nights. More storms will develop once again on Monday, but drier air will start to move into the region so precipitation chances will decrease over the coming days until most of the activity is mostly isolated to the high terrain by midweek. Relative humidity will approach critical levels by midweek with southwesterly winds increasing towards the end of the week which will lead to locally critical fire weather conditions. ***Thunderstorms imply strong, gusty and erratic winds*** ***All winds are 20 foot, 10-minute averages*** UTZ478-240030- Salt Lake Desert- 337 AM MDT Sun Aug 23 2026 .TODAY...
