An upward trend of dewpoints and relative humidity shown from recent surface observations across portions of southern NV and southwestern UT should limit fire weather threat for the area today as monsoon moisture increases from the south. Elevated highlights remain across east-central NV and west-central UT where breezy winds, daytime relative humidity at or below 15 percent and dry fuels align. Otherwise, a broad dry thunderstorm threat was maintained for much of the Great Basin and Upper Colorado River Basin this afternoon. More concentrated high-based thunderstorms with minimal rainfall are expected across the Western Slope and eastern Utah where scattered dry thunderstorm highlights remain. ..Williams.. 07/16/2025 .PREV DISCUSSION... /ISSUED 0141 AM CDT Wed Jul 16 2025/ ...Synopsis... A departing mid-level trough will bring continued breezy conditions across portions of southern Nevada into west-central Utah. This will overlap with relative humidity reductions around 10-15 mph bringing Elevated fire weather conditions. In addition to the background flow, nearby high based convection will likely bring gusty and erratic winds. ...Dry Thunderstorms... A broad area of dry thunderstorms is expected across northern AZ into western CO, UT, southern WY, and portions of eastern NV. Across western Colorado into eastern Utah, forcing for ascent with the upper-level trough will aid in more scattered coverage of thunderstorm activity. Sounding profiles within this region show elevated instability amid very dry low-levels which will promote high based convection with efficient lightning production and little to no measurable precipitation. Fuels within this region remain critically dry with several ongoing fires. ...Please see www.spc.noaa.gov/fire for graphic product... $$
