008 FXUS65 KBOU 050520 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 1020 PM MST Tue Nov 4 2025 .KEY MESSAGES... - Generally quiet and dry conditions through the next several days. - Elevated fire conditions are expected on Thursday and Saturday across portions of the eastern plains. - Weak systems will bring very light snow to the northern mountains Thursday and Saturday. && .DISCUSSION /Through Tuesday/... Issued at 245 PM MST Tue Nov 4 2025 Another day of record or near-record highs occurred today with many areas across the plains hitting the upper 70s and temperatures hitting the mid 60s in the mountain valleys. A weak cold front is currently in northeast Wyoming and across South Dakota that will move across our forecast area late tonight. This will turn winds to the northeast in the morning hours across the plains and will keep temperatures 5-10 F cooler on Wednesday. A DCVZ will setup on the east side of Denver metro with highs around 70 on the east side and highs in the mid 60s on the west side. There are two main things to discuss in the long term besides the generally mild and dry conditions. Those are multiple days of elevated fire weather conditions and two very light snow events for the northern mountains. As for fire weather, Thursday will be mild, dry, and breezy over the northern-most counties across the plains. This will lead to elevated to near critical fire weather conditions from Greeley to Holyoke and north to the WY and NE borders. On Saturday, wind gusts up to 35 mph will spread across all of the eastern plains. Temperatures will be closer to normal so relative humidity will drop to around 20% which will result in elevated fire weather conditions. The other days during the long term period will see winds and humidity that will be lower than Red Flag criteria. As for winter weather, a trough on Thursday and another early Saturday morning will bring just enough moisture and orographic forcing to the northern mountains of Colorado to produce snow. The Park Range will see the highest snowfall amounts but only a couple of inches will fall. Ensemble guidance doesn`t show a decent signal for precipitation across our forecast area until November 14-16th. Even then, it is highly uncertain the plains will receive precipitation during this period. Otherwise, temperatures will be 10-15 F above normal with a chance for record highs especially Monday and Tuesday of next week. && .AVIATION /06Z TAFS through 06Z Thursday/...
