NWS Pueblo, CO wrote its last area forecast discussion before the first event at Dec 17, 10:36 AM MST, 2 hours 47 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pueblo CO 1036 AM MST Wed Dec 17 2025 .KEY MESSAGES... - Damaging winds and blowing snow are expected over portions of the high country beginning this morning. - High Fire Danger is expected on the plains today, with damaging winds moving in later this afternoon and reaching a peak through the later evening hours. - Elevated fire weather conditions possible again Thursday and Friday on the plains. - Brief cool down Thursday, then very warm Friday and Saturday before another minor cool off on Sun. Quick peak at the holiday week from Mon onward suggests warm and dry weather continuing. && .SHORT TERM /THROUGH TONIGHT/... Issued at 210 AM MST Wed Dec 17 2025 Currently.. Northwest flow aloft persists with just a few high clouds on satellite imagery early this morning, mainly over our northern and eastern plains. Temperatures are mild and far warmer than normal, with most locations still sitting in the 30s and 40s on the plains. Canon City is still 48F as of 2 AM, and Trinidad is still 37F. Dewpoints are mainly in the teens above zero. Today and Tonight.. Most of today will be a lead up to this evening's damaging wind event, though dangerous fire weather conditions and High Winds will exist throughout the daytime hours as well. As the incoming system approaches through the daytime hours, we will be downsloping and warming drastically across the area, which will bring about another day of temperatures in the high 60s and 70s. Though records are not expected today, we will be every bit as warm as yesterday, which did break records in both the Springs and Pueblo. Today's records are much higher, and are reflective of all time December records for Pueblo. 82F is Pueblo's record, and 75F is Colorado Springs. Both were set in 1980. Current forecast is 68F for the Springs and 72F for Pueblo. Our High Wind Warning for the central mountains and Teller County goes into effect at 11 AM this morning, where gusts to 80 mph will be possible. The High Wind Warning for the lower elevation zones all along the I-25 corridor, and through Fremont County, goes into effect at 2 PM. These areas can expect gusts to 60 mph. Both wind warnings are valid until 3 AM Thursday morning. All of our plains and Fremont County are also under a Red Flag Warning from 11 AM through 6 PM this evening. If there is good news about the Fire Danger for today, its that the strongest winds are expected later in the day and after sunset, which will help to mitigate the fire weather threat. Though dewpoints themselves will not truly increase substantially over the next several days, humidity values will technically recover as the temperatures cool this evening. This will help to mitigate fire weather risks after sunset. Many areas in the RFW look to see recoveries in the 30 to 40% range tonight into Thursday morning, with minimum values this afternoon in the low to mid teens. This trend will need to be closely monitored with these extreme winds today, and people in all areas should take care not to start a wildfire today. A quick bout of wind driven snow will also be possible over the central mountains through the higher terrain of Lake and Chaffee counties. Though new snow totals will be too low to warrant any highlights, visibilities will be degraded due to strong winds. Travel could be very difficult due to blowing snow. A quick 3 to 6 inches will be possible for higher peaks, with a couple of inches possible for Leadville by this evening as well. Models bring the northern plains low into eastern Montana by this evening, with the 170kt jet core making its way into our region by around 9 PM. This looks to be the beginning of the strongest winds for most of the mountain adjacent plains. The strongest jet support slides east by around 3 AM, keeping strong winds over much of the area straight through the overnight hours. Be sure to secure loose objects early today, because the strongest winds are coming after sunset and they may be difficult or dangerous to find in the dark! Gusts to 60 mph are expected for most areas along and west of I-25 from late this afternoon through 3 AM this morning && .LONG TERM /THURSDAY THROUGH TUESDAY/... Issued at 210 AM MST Wed Dec 17 2025 Still windy on the plains Thursday, as upper low wraps up over Minnesota, with brisk 40-50 kt 700 mb flow over the far east from early morning into midday. Could get some gusts 50-60 mph early Thu morning over ern Kiowa/Prowers counties, but with strongest winds shifting eastward by 18z, it doesn't like quite windy enough for a high wind warning at this point. Relative humidity tanks along and east of the mountains Thu as surface dewpoints fall off into the single digits, leading to a couple hours of near Red Flag conditions (15 percent RH and winds over 25 mph), especially near the KS border. Not sure if we'll meet the 3 hr time duration given rather cool temperatures, so will hold off on a fire highlight for now. Back along I-25 and over the mountains/valleys, breezy and cooler conditions expected, with a gradual decrease in winds during the afternoon. Warm air returns on Friday under brisk wly flow aloft and rising mid-level temperatures, and many lower elevations will reach the 60s/70s for maxes by late day. Lee surface trough on the plains and strong flow aloft (30-40 kts at 700mb) suggest afternoon winds will become gusty and strong, leading to another day of elevated fire weather conditions on the plains. Dewpoints do rise slightly back into the teens and 20s, which will make minimum humidity marginal once again, so will hold off on any highlights, though suspect deeply mixed areas south of the Arkansas River will be at least close to critical for much of the day. Similar set-up for Sat, though weak front backs westward across the plains in the afternoon, shaving a few degf off of max temps and helping limit fire danger slightly. Central mountains could see some snow showers Sat as wave brushes by to the north, though any accumulations will be light. After a cooler day on Sunday, warm, dry and breezy weather returns for much of the holiday week, as broad upper ridge migrates from the Rockies into the central plains through the period. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1036 AM MST Wed Dec 17 2025 Upper jet crossing the state today will produce strong westerly flow across the higher elevations and adjacent plains, primarily affecting KCOS and KPUB this afternoon and tonight. Time window for strongest potential gusts along the entire I-25 Corridor will be 22z- 10z with gusts to 50-55 kts possible. Mentioned wind shear for both KCOS and KPUB 18z-20z, before stronger west winds surface at those sites. Surface cold front drops south across the Palmer Divide starting around 12z-13z tomorrow morning. For KALS..VFR conditions expected with slightly less effects from stronger winds, though forecast west wind gusting to 22 kt between 02z and 07z. Also mentioned wind shear from 02z-11z. && .PUB WATCHES/WARNINGS/ADVISORIES... High Wind Warning until 3 AM MST Thursday for COZ058-060-061- 081-082.

Strong winds with gusts to 60 mph move into the I-25 corridor and portions of the eastern and Wet Mountains, by 2 PM, and may pose travel risks to light weight and high profile vehicles, especially on north-south oriented roadways, including I-25. Strongest gusts will be from late afternoon through the overnight hours. High Fire Danger is also expected for all of our plains and Fremont County today, with humidity values in the low teens and gusts to 55 mph through the daylight hours. Please take extra care not to start a wildfire today! A quick bout of wind driven snow is expected over the central mountains through the higher peaks of Lake and Chaffee counties, where 3 to 6 inches will be possible. Visibilities will be degraded in strong winds and travel may be difficult at times, especially through mountain passes! .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Another round of snow showers will be possible over the central mountains during the weekend, though snowfall amounts look to remain light. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible over portions of the region. EHR/10
