516 FXUS65 KBOU 101821 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 1121 AM MST Tue Nov 10 2026 .KEY MESSAGES... - Above normal temperatures and dry conditions will likely prevail through Friday. - Increasing chances for light mountain rain/snow showers by this weekend. && .DISCUSSION /Through Tuesday/... Issued at 1121 AM MST Tue Nov 10 2026 Our trend of above normal temperatures (10-15 degrees), continues as today`s high temperatures will be in the upper 60s and lower 70s for the plains. More cloud cover is expected as a shortwave tracks north of Colorado today and into the Great Plains Wednesday. This shortwave also allows the push of a weak front into our region this afternoon/evening increasing wind gusts up to 20-30 mph along the area of the Cheyenne Ridge. Elevated fire weather conditons will be possible, but relative humidity values are expected to stay above critical thresholds. The passage of this weak front will cause Wednesday`s high temperatures to be slightly lower in the low to mid 60s. Quiet weather will continue through the rest of the work week as the upper level ridge axis dominates our area through Friday. High temperatures will be in the mid to upper 60s, but a few solutions favor reaching or exceeding 70F. At this time, the chances of temperatures exceeding 70F are about 20-40% for Thursday and Friday. For the advertised system over the weekend, models appeont wiar to be trending more bullish on the rain and snow potenital for both the mountains and the plains. Generally, a low pressure system moves into SW Colorado and Northern New Mexico Saturday evening before lee- cyclogenesis produces a potential surface low near far southeastern Colorado. This will give us our next chance for snow showers for the higher terrain and rain for the plains. Intensity and placement of this low/trough will likely determine accumulation totals. Cooler temperatures are also expected with highs on the weekend in the upper 50s and lower 60s. Monday should be a pleasant fall day before our next storm system moves in around mid-week. && .AVIATION /18Z TAFS through 18Z Wednesday/... Issued at 1050 AM MST Tue Nov 10 2026 VFR will continue to prevail through the TAF period. Gusty northwest winds along the Cheyenne Ridge to north of Denver will produce an anti-cyclonic wind pattern over the Denver area today. For DEN, winds are expected to continue turning clockwise, becoming southeast later this afternoon. Winds are expected to remain light (less than 10 knots) under this pattern. A weak cold front may bring a brief period of north to northeast winds from 02Z to 05Z. After this, winds are expected to settle at a southerly drainage direction. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Schnell AVIATION...BM
