799 FXUS65 KBOU 011126 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 526 AM MDT Fri May 1 2026 .KEY MESSAGES... - Mountain snow decreasing overnight. Light mountain snow remains possible Friday afternoon. - Warmer and drier conditions expected for the weekend. - Unsettled weather returns Monday night through Wednesday with increasing chances for mountain snow and rain showers over the plains. && .UPDATE... Issued at 341 AM MDT Fri May 1 2026 Snow showers have tapered off considerably in the mountains, with light showers mainly confined to Park County at this hour. As such, have canceled the Winter Weather Advisory a couple of hours early given that additional travel impacts are no longer expected. && .DISCUSSION /Through Thursday/... Issued at 1140 PM MDT Thu Apr 30 2026 The current unsettled stretch of weather comes to a close on Friday before unsettled weather returns early next week. Current radar imagery shows light snow showers for the southern Front Range mountains and some light rain showers across the plains. Mountain snow showers remain possible through early Friday morning for the southern Front Range mountains, where a Winter Weather Advisory remains in effect until 6am Friday. Portions of the Palmer Divide and southern foothills will likely see decreasing showers through the night. Friday will see temperatures about 10 degrees warmer than Thursday- highs in the upper 50s to low 60s for the plains. Dry air will be moving in from the north as the day progresses. A 40-60% chance for light mountain snow showers will continue on Friday with the highest chances for the southern Front Range mountains. Additional accumulations of only 1 to 3 inches of snow is expected during the day on Friday. Otherwise, across the plains, the chance for any rain showers is quite low (around 10%), with only 0.05" QPF at most. An upper level ridge will build into the area for Saturday and Sunday leading to mostly sunny skies. Highs will top out in the upper 60s to low 70s across the plains on Saturday with Sunday being slightly warmer. By Monday, an upper level low will be located near California and slowly moving eastward throughout the week. The jet stream will move in from the north giving way to north/northwest flow and bringing increased cloud cover for Monday. This will lead to the possibility of showers for the plains and snow for the mountains Monday afternoon through Tuesday night. It is still too early to provide specific amounts, but this is a favorable pattern for measurable QPF. Although, it is important to note that recent ensemble guidance has trended down in QPF amounts. Currently, the Front Range mountains and foothills are favored to receive the most precipitation from this system. With the arrival of showers overnight Monday and into Tuesday, cooler temperatures are expected, with most of the plains hovering around high 50s to low 60s. A cold front will move through the region on Tuesday night and continue below temperatures for Wednesday. Low precipitation chances (20-30% chance) could linger into Wednesday and Thursday, mainly for the mountains, depending on the progression of the system. Guidance is in good agreement of temperatures returning back to the 70s as high pressure starts to build back in late next week. && .AVIATION /12Z TAFS through 12Z Saturday/... Issued at 522 AM MDT Fri May 1 2026 VFR conditions are favored to prevail for all terminals through the TAF period. There`s a 3-4 hr window (~17-21Z) where FEW-SCT clouds with lower bases (040-060) could develop, though more likely for KAPA than KDEN or KBJC. Winds will remain very light through the day, with current SW drainage flow transitioning to a N/NE wind at the terminals late morning. In theory, winds should favor a clockwise transition back to drainage flow in the evening, although some variability in direction looks quite plausible for this evening. Expect winds to remain below 10 kts through the day. Any lingering mid/high-level cloud cover will clear overnight. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ UPDATE...BRQ DISCUSSION...MV AVIATION...BRQ
