375 FNUS55 KSLC 200814 FWFSLC Fire Weather Planning Forecast for Utah National Weather Service Salt Lake City UT 214 AM MDT Wed Aug 20 2025 ...MOISTURE INCREASING LATTER HALF OF WEEK INTO NEXT WEEK... .BROADCAST DISCUSSION...Hot and dry conditions are expected today, with chances for isolated dry thunderstorms across northwest and south-central Utah this afternoon. Monsoonal moisture gradually increases across the region through the latter half of the week, bringing higher humidity and more widespread wet showers and thunderstorms. .DISCUSSION...Conditions remain hot and dry today, though increasing mid-level moisture will lead to the development of isolated high- based showers and thunderstorms across far northwest and south- central Utah this afternoon. Dry lightning strikes and gusty, erratic outflow winds will be the main concern for any thunderstorms that develop. Moisture deepens across Utah through the remainder of the week, with thunderstorms gradually transitioning from mainly dry today to mainly wet by Friday. Chances for widespread wetting rains increase mainly across southern Utah through the weekend and into early next week as monsoonal moisture continues to overspread the region. ***Thunderstorms imply strong, gusty and erratic winds*** ***All winds are 20 foot, 10-minute averages*** UTZ478-210030- Salt Lake Desert- 214 AM MDT Wed Aug 20 2025 .TODAY...
