FNUS55 KSLC 221000 FWFSLC Fire Weather Planning Forecast for Utah National Weather Service Salt Lake City UT 400 AM MDT Sat Aug 22 2026 ...MOISTURE GRADUALLY DECREASING AFTER THIS WEEKEND... .BROADCAST DISCUSSION...Light rain across northern Utah will end by early morning. More storms develop this afternoon across the northern 2/3rds of Utah that will transition to light rain once again across northern Utah Saturday night. Conditions start to gradually dry next week. .DISCUSSION...Light rain continues to linger across northern Utah that will dissipate by early morning. Moisture will remain elevated across the region with more storms developing Saturday afternoon. Most models have the southern 1/3rd of Utah remaining relatively dry today with most of the activity across central and northern Utah. These storms that develop today will likely weaken and linger into the overnight hours across northern Utah, similar to the activity that occurred tonight. These afternoon storms will be capable of frequent lightning along with gusty and erratic winds. After today moisture will gradually start to decrease across the region, particularly across southern Utah. Precipitation chances will remain through midweek before flow aloft becomes more westerly during the second half of the week. This will bring much drier air into the area with minimum relative humidity decreasing back into the teens with recoveries in the 30s and 40s. Winds will also be increasing as conditions dry. ***Thunderstorms imply strong, gusty and erratic winds*** ***All winds are 20 foot, 10-minute averages*** UTZ478-230030- Salt Lake Desert- 400 AM MDT Sat Aug 22 2026 .TODAY...
