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 appear to be trending more bullish on the rain and snow potential 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 /00Z TAFS through 00Z Thursday/... Issued at 432 PM MST Tue Nov 10 2026 VFR conditions expected throughout the TAF period. Light winds are expected to become northerly or northeasterly around 01-02Z and last for 3-4 hours. However, there is some uncertainty with regards to whether these northerly winds will develop at all as very few observations north of the Denver metro currently indicate northerly winds. If the northerly winds don`t develop, light and variable or light southerly winds would develop. There will then be typical drainage winds late this evening through the overnight period. On Wednesday, a very light southeasterly wind will become northeast or east during the afternoon. Winds will become drainage Wednesday evening and will last throughout the night. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Schnell AVIATION...Danielson
