165 FXUS65 KBOU 061130 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 530 AM MDT Wed May 6 2026 .KEY MESSAGES... - Ongoing snowstorm is reaching its tail end, with snow showers subsiding from north to south throughout the morning, and all areas dry by this evening. - Travel impacts can still be expected at times for the I-70 mountain/foothill corridor today. Elsewhere, minor additional accumulations may continue to stress weighted trees and power lines through this morning. - Widespread freeze expected tonight for all areas. - Return to a warmer weather for the latter half of the week into early next week, with just a couple chances of showers and storms due to passing disturbances. && .UPDATE... Issued at 522 AM MDT Wed May 6 2026 One last hoorah of more widespread snow showers is expected over the next 2-4 hours for the urban corridor before subsiding more noticeably mid to late morning. Headlines will likely be able to be dropped early for many areas. An inch or two of additional accumulation will be possible for colder surfaces, but roadway accumulations are unlikely outside of brief dustings coinciding with the heaviest snowfall rates. As soon as that intensity drops, any accumulated snow will melt and give way to just wet roads. && .DISCUSSION /Through Tuesday/... Issued at 1226 AM MDT Wed May 6 2026 The upper trough and accompanying QG ascent will move across the area overnight thru late Wed morning and then exit the area by aftn. Latest cross-sections show weak upslope component over the area but should see a period of enhancement after 09z thru mid morning on Wed. So still expect a band of heavier snow to spread across the area overnight thru mid morning. Activity will then gradually end from north to south by late morning thru the aftn hours. With clearing skies Wed night still expect a hard freeze across much of the plains thru Thu morning. On Thu, NW flow aloft will be over the area as a weak disturbance moves across Thu night. As a result will see a chc of snow showers in the mtns with a slight chc of rain showers across the plains mainly Thu night. Highs on Thu will quickly rebound as readings warm back to the mid 60`s to near 70 across the plains. By Fri, the flow aloft will stay NW with mainly dry conditions expected. Highs will be in the upper 60`s to lower 70`s over the plains. For Sat, another weak disturbance embedded in NW flow aloft may affect the area bringing at least a slight chc of showers or tstms to the area. Highs will be in the 70`s over nern CO. By Sun into Mon, the flow aloft will be more WNW. At this time, it looks dry, with highs rising into the lower to mid 80`s across the plains by Mon. && .AVIATION /12Z TAFS through 12Z Thursday/... Issued at 522 AM MDT Wed May 6 2026 One last window of enhanced snow shower activity is expected through the next 2-4 hours for Denver area terminals, with potential for brief vis restrictions to 1/2-1SM during the heaviest snow. Otherwise, expect vis ranging 3-6SM with isolated -SHSN activity through mid-morning, diminishing substantially past 15Z. Have trended lifting CIGS and vis notably earlier in line with current radar observations and most recent model guidance. VFR conditions could return as early as 23Z, but more likely will still hold off until early evening. North winds may see a slight increase after 13Z with speeds 10-13 kts associated with this last pronounced surge of snow showers. After that, expect generally N and NNE flow, weakening in the evening and returning to drainage flow. The SW winds should keep fog potential at bay tonight. && .BOU WATCHES/WARNINGS/ADVISORIES...
