089 FXUS65 KBOU 241930 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 130 PM MDT Wed Sep 24 2025 .KEY MESSAGES... - Warmer and dry for the rest of the week. - The next disturbance(s) will be weak, bringing scattered light precipitation late Sunday through Tuesday, mainly for the mountains. && .DISCUSSION /Through Wednesday/... Issued at 130 PM MDT Wed Sep 24 2025 Our weather will be dominated by an upper level ridge which will build and hold across the state through Saturday. This will support sunny skies, dry conditions, warm daytime temperatures, and light winds. High temperatures each day will be several degrees above normal. A weak backdoor cold front Friday night is expected to bring slight cooling (just 2-5 degrees) to the plains for Saturday. The next chance of any precipitation won`t arrive until late Sunday as eventually the ridge moves off to the east and a shearing trough lifts out of the Desert Southwest. For the most part, moisture associated with this trough stays to our west, and therefore the main chance of showers and storms will be confined to the mountains and western Colorado. While there is more uncertainty in the trough position and any potential shortwaves Tuesday into Wednesday, there is reasonable agreement we`ll stay in some sort of southwest flow. Thus, the main chance of any showers or storms will stay over the mountains and western Colorado. This pattern would also be favorable for a continuation of above normal temperatures through the middle of next week. && .AVIATION /18Z TAFS through 18Z Thursday/... Issued at 1141 AM MDT Wed Sep 24 2025 There is some concern for SCT-BKN clouds 4500-6000 feet through about 23Z, but main threat for BKN should stay just south and east of KDEN. Otherwise VFR conditions will persist through the period, with clear skies 02Z onward. Light and normal diurnal wind patterns will prevail at speeds 10 kts or less. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Barjenbruch AVIATION...Barjenbruch
