687 FXUS65 KBOU 081126 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 426 AM MST Sun Nov 8 2026 .KEY MESSAGES... - Above normal temperatures and dry conditions are expected for at least the next seven days. && .DISCUSSION /Through Saturday/... Issued at 1033 PM MST Sat Nov 7 2026 Upper level high pressure will further build into the area Sunday and Monday, keeping well-above normal temperatures and dry conditions across the area. Mostly sunny to partly cloudy skies are forecast for the next two days, with highs approaching 70 degrees each afternoon for portions of the plains. On Tuesday, the flow aloft becomes more zonal, and potentially even a little northwesterly. A shortwave trough is forecast to approach the area from the northwest, bringing slightly cooler temperatures aloft and increased cloud cover for Tuesday afternoon. This will allow temperatures to drop a few degrees for Tuesday afternoon in the higher terrain and portions of the plains. A cold front is forecast to move through sometime mid Tuesday into early Wednesday. Models vary pretty significantly with the positioning and strength of the shortwave and therefore the strength of the cold front. The GFS wants to bring the shortwave further south into the area, with a much stronger cold front. It also brings the 700mb jet over the northeast plains, putting breezy winds across the area late Tuesday into Wednesday. This solution would allow for low end rain chances in the higher terrain, warmer temperatures across the northern plains on Tuesday from strong downsloping, and cooler temperatures Wednesday. However, other models have a less potent shortwave staying more to our northeast. With this solution precipitation chances would remain near zero, surface winds would be much lighter, and temperatures would drop slightly for the middle of the week, but not as significantly as the other scenario. For Thursday into the weekend, an upper level ridge builds over the area, bringing temps back to 10-15 degrees above normal for the plains on Friday. Looking at ensembles, there is not a single member of the most recent GFS and ECMWF runs that have even a trace of rain for Denver over the next 7 days, so confidence is high in conditions staying dry for the plains (unfortunately). && .AVIATION /12Z TAFS through 12Z Monday/... Issued at 426 AM MST Sun Nov 8 2026 VFR conditions will persist through the TAF period, with only FEW-SCT high clouds above 20,000 ft AGL and no visibility restrictions. Light winds will prevail. Southerly winds around 7-10 kts will persist at KDEN through about 18Z, before likely turning a bit more southeasterly and then likely VRB toward 22Z. Look for a transition back to normal S-SW around 10 kts by 02Z. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...AP AVIATION...20
