If conditions become unrepresentative...contact the National Weather Service. ...RED FLAG WARNING IN EFFECT UNTIL 9 PM MDT THIS EVENING... .DISCUSSION...A ridge of high pressure will continue to slowly nudge eastward, producing further warming and drying, and centering over Utah by late Thursday and early Friday. In the meantime, winds will continue to slowly lighten up, becoming largely diurnally-driven by Wednesday night. Wednesday and Thursday will still feature critically low RH during the daytime and poor overnight recoveries, with the poorest recoveries expected Wednesday night, barely reaching the upper-teens. The first hint of a pattern change is on Thursday, with a very low (10%) chance of high-based showers over higher terrain. As the high pressure continues to nudge further eastward, moisture will start to wrap around from the south, producing increasing chances for dry lightning on Friday, and then scattered showers and thunderstorms heading into the weekend. The low levels are looking likely to remain dry, thus gusty and erratic outflow winds and microburst are possible through the weekend. This will also increase RH, with overnight recoveries greatly improving by Saturday night. Daytime RH may still remain critical through Friday and potentially Saturday as well before finally improving above 15%. .WEDNESDAY... Sky/weather.........Sunny (0-10 percent cloud cover).
