FNUS55 KSLC 231825 FWFSLC Fire Weather Planning Forecast for Utah National Weather Service Salt Lake City UT 1225 PM MDT Sun Aug 23 2026 ...THUNDERSTORM THREAT CONTINUES THROUGH MIDWEEK... .BROADCAST DISCUSSION...High pressure will remain across the 4 Corners region through the next week. Showers and thunderstorms will continue each afternoon and evening, especially across the higher terrain and adjacent valleys through Wednesday. Humidities will gradually fall for most locations, reaching critical levels for most valleys by midweek. .DISCUSSION...High pressure will remain across the Four-Corners region through the next week. As an upper level low crosses southern Canada into the northern Intermountain Region through Monday, sufficient forcing for thunderstorms will continue. As a result, strong to severe thunderstorms will impact much of northern Utah this afternoon and evening. The most significant threat will be strong outflow winds in excess of 60 mph, mainly north of I-70. For locations south of I-70, strong outflow winds up to 50 mph and very heavy rain will be the primary impacts from thunderstorms. Additional strong thunderstorms will develop Monday afternoon and evening, but the threat of outflows in excess of 50 mph will remain closer to the Utah/Idaho border. As high pressure builds north and east in the wake of the upper level low Tuesday, thunderstorms will become more confined to the higher terrain and adjacent valleys through Thursday. A net drying trend will continue, with most valleys see humidities fall to critical levels by midweek. Another round of thunderstorms may impact more of the state as early as Friday as another low pressure area impacts the Pacific Northwest and pulls moisture from the tropical Pacific northeastward into the Great Basin. ***Thunderstorms imply strong, gusty and erratic winds*** ***All winds are 20 foot, 10-minute averages*** UTZ478-241400- Salt Lake Desert- 1225 PM MDT Sun Aug 23 2026 .TONIGHT...
