What forecasters said that day
The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this red flag warning went out at Jan 16, 10:43 AM MST, 3 hours 32 minutes earlier. Its key messages:
- Strong winds (50 to 70 mph gusts) and critical fire weather conditions to prevail over northeast Colorado today. Red Flag Warnings have been extended into the western Denver metro, Palmer Divide and southern Lincoln county.
- Blowing dust will be a concern as well, with dangerous travel conditions and potential for Dust Advisory and/or Dust Storm Warning(s) as winds strengthen today.
- Colder today and Saturday, but some fire weather concerns linger into Saturday especially on the northeast plains.
- More tranquil weather Sunday onward. Still dry through much of the week ahead.
Area forecast discussion, Jan 16, 10:43 AM MST, 3 hours 32 minutes before
Area Forecast Discussion National Weather Service Denver/Boulder CO 1043 AM MST Fri Jan 16 2026 .KEY MESSAGES... - Strong winds (50 to 70 mph gusts) and critical fire weather conditions to prevail over northeast Colorado today. Red Flag Warnings have been extended into the western Denver metro, Palmer Divide and southern Lincoln county. - Blowing dust will be a concern as well, with dangerous travel conditions and potential for Dust Advisory and/or Dust Storm Warning(s) as winds strengthen today. - Colder today and Saturday, but some fire weather concerns linger into Saturday especially on the northeast plains. - More tranquil weather Sunday onward. Still dry through much of the week ahead. && .UPDATE... Issued at 327 AM MST Fri Jan 16 2026 Forecast is consistent and the main message today remains strong, gusty winds, high fire danger, and blowing dust with potential for dangerous travel conditions over the northeast plains. To start with, for a rarity as of late, we actually had some stratus development behind last night's blast of a cold front. Even a few flurries were noted in a couple spots. That, however, is already dissipating into a mid level cloud deck and further erosion will occur as strong subsidence builds in this morning. That will begin in earnest as the jet axis slides just to the east, putting the Front Range into the right exit region of the upper jet. Per last evening's discussion, that puts the I-25 Corridor in stronger subsidence and stronger wind potential (despite some blocking in NW flow), so the upgrade to the Red Flag Warning for Boulder, western Denver suburbs, and Palmer Divide is on track. While winds may "only" gust to around 50 mph here, the rest of the northeast plains will likely gust to 60+ mph with a few wind prone spots still having potential for gusts to 70 mph. Plan views show a 500 mb wind core of 90-100 kts dropping across the area today, with 600 mb wind core near 80 kts, and 700 mb wind core of 55-65 kts! With the added subsidence, we appear to mix just shy of 700 mb, and thus we expect widespread wind gusts to reach 55 kts (~65 mph) across the plains. Some of our wind prone areas (mountain peaks and northern I-25 Corridor north of Wellington will almost certainly hit 70+ mph). Thus, all High Wind Warnings look good and will remain in place. With the recent dryness and high winds, blowing dust will be a big concern today. We have all the ingredients for dust storms; high (dry adiabatic) lapse rates in the lowest 2km, humidity down into the teens, recent extreme dryness with poor soil moisture, and lack of ground cover due to crop dormancy. The only limiting factor at this point would be high level cloudiness which could limit solar insolation and mixing slightly. However, even last night's front reduced visibility in some locales, and impacts would be more pronounced today with daytime traffic loads and more persistent winds with the above noted ingredients. Dust Storm Warnings and/or Advisories are a distinct possibility from late morning through much of the afternoon over the northeast plains, with the highest risk in agricultural areas including portions of I-70 and I-76 east and northeast of Denver. Winds are expected to decrease by early evening, but that's not the end of it. It will stay gusty to some extent (30-40 mph) over most of the plains east of I-25 overnight due to the persistent gradient and only slight weakening of the flow aloft. Similar gusty winds can be expected on Saturday (35-45 mph) over the eastern plains, while the western suburbs of Denver should stay more sheltered. That means another day of elevated to critical fire weather conditions across the plains - see Fire Weather Discussion for more details. Much of next week continues to look dry. Mild days will be interrupted by additional backdoor cold fronts in this pattern. Maybe, just maybe, some (light) snow arrives in the mountains toward Friday. UPDATE Issued at 942 PM MST Thu Jan 15 2026 It's not often that we see a strong cold front followed by critical fire weather conditions the following day... but unfortunately, that is the forecast here. This evening's cold front was a stronger than most guidance had suggested, with just about everywhere in the lower elevations seeing 45-55kt winds over the last couple of hours. The post frontal airmass isn't particularly moist, but there is enough shallow moisture for some stratus along the base of the foothills and closer to the Wyoming border. There could be a few light snow showers but at this point anything more than a dusting looks unlikely. The bigger changes to the forecast come tomorrow. The early window of overnight guidance is much more bullish developing strong winds along and west of the I-25 corridor from Denver into the Palmer Divide. While these areas typically remain well sheltered in NNW flow aloft, the combination of strong QG subsidence, a belt of 90kt 500mb flow, and the nose or right exit region of an upper jet streak would all favor some stronger winds developing there. While the stronger winds should still set up along and northeast of a Fort Collins to Limon line. Finally, it's hard to overlook a rather consistent signal from the HRRR/RAP bringing in much drier air than originally anticipated. That matches well with previous experience in these downslope/strongly subsident regimes. This is also broadly supported by newer runs of the RRFS which are typically a bit more conservative with RH forecasts... and that thought, coupled with the potential for stronger wind gusts in the south/west Denver metro has led to an expansion of the Red Flag Warning into the rest of our lower elevation zones for tomorrow. && .DISCUSSION /Through Thursday/... Issued at 233 PM MST Thu Jan 15 2026 Water vapor satellite imagery showing a shortwave trough diving south-southeast across eastern Montana. This wave races southeastward helping to carve out large upper level low over the Great Lakes Friday. This will leave Colorado under a strong north- northwest flow aloft with a 120 knot jet overhead. A strong cold front associated with the shortwave trough is racing south across southern Montana and northern Wyoming. Wind speeds are 50 to 60 mph with the cold front passage. We earlier upgraded the High Wind Watch to a Warning and moved up the timing to mid to late evening to capture the stronger winds that will accompany the cold front. The strong winds linger up to a couple hours behind the cold, then we will see a lull in the stronger winds until Friday morning. There's a brief period after midnight where there may be enough lift and moisture for a few snow showers. Any accumulation is expected to be light. Subsidence and fierce drying occurs Friday morning with relative humidity falling into the teens by late morning and early afternoon. The subsidence and mostly clear skies will help mix the stronger winds aloft down to the surface, so we look on track to see 60 to 70 mph wind gusts across the plains Friday. The 12Z GFS and ECMWF models show the trough axis and thus the jet has shifted westward by a county or two. This lines up with 12Z HRRR and the expansion of the High Wind Warning southwestward. Because of the low relative humidity and strong winds, upgraded the Fire Weather Watch to a Red Flag Warning for much of northeast Colorado. Winds slowly decrease mid to late afternoon Friday, but gusty north winds linger into the overnight hours. The winds will help keep the airmass mixed and keep temperatures from getting too cold. However, the airmass has an arctic origin, so lows are expected to be in the teens and single digits. Saturday will see decreasing winds but overall similar dry and windy conditions. Fire weather conditions may be critical across the majority of the plains and this is discussed in the fire weather section below. A strong trough aloft will move over northeast Colorado with the axis of the trough moving through our forecast area Saturday morning. There will be strong subsident flow with very dry air moving in on the backside of the departing trough. Wind gusts will reach 45 mph across the plains with the highest values in Weld and Washington Counties. Temperatures will be cool with highs in the 30s across the majority of the plains. Wind chills will be in the low 20s to teens especially Saturday evening. A brief ridge within the northwesterly flow will move across Colorado on Sunday. This will lead to temperatures warming up 15-20 degrees above the high on Saturday. There will be mostly sunny and dry conditions. Another trough moves through on Monday leading to cooler and windier conditions. There is such little moisture with these systems that only very light snow will be possible in the mountains with no impacts from this trough. The flow aloft will become more zonal during the middle of next work week leading to mild temperatures. The lack of moisture continues so no precipitation is expected. Ensembles by the following weekend have a very large spread with temperatures. What is noteworthy about the ensembles is that there could be very cold air coming into Colorado. There's about a 20% chance that temperatures get below 0 F across our entire forecast area the weekend of January 24-25. && .AVIATION /18Z TAFS through 18Z Saturday/... Issued at 1043 AM MST Fri Jan 16 2026 North winds are expected to persist through Saturday and DEN. The strongest winds are expected this afternoon 20-23Z with gusts to 40 knots, which could produce blowing dust restrict visibility. Winds decrease towards sunset, but stay gusty with gusts up to 35 knots. Late tonight and into early Saturday morning, winds could briefly turn to a southwest drainage direction. This will be short-lived as gusty north winds are expected to develop Saturday morning. KBJC and KAPA will be slightly sheltered in NNW flow, but still expect occasional gusts to 28-38kts during the peak of the winds 20Z-23Z. VFR conditions will persist through this TAF period, but a small (30%) chance ceilings drop low enough for IMC after 00Z tonight. && .FIRE WEATHER... Issued at 327 AM MST Fri Jan 16 2026 The Red Flag Warning for today was expanded last evening to include the rest of the I-25 Corridor including the western Denver suburbs, Boulder, and the Palmer Divide as we now anticipated the drier and windier conditions (just not as terribly windy) to envelope those areas for the afternoon. Strong winds decrease around sunset Friday, but breezy to windy conditions may linger through the night in some places. Despite the colder temperatures, a much drier airmass will mean critical fire weather conditions, and potential for fast moving wildfires should any new fires start. On Saturday, it will stay colder, but a very dry but windy pattern will remain over the forecast area. Relative humidity will fall to 12-22%, and with gusts across the plains 35-45 mph, critical fire weather conditions are possible. The driest airmass is expected to reside over the northeast plains, so we've issued a Fire Weather Watch for Zones 248>251. && .BOU WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 6 PM MST this evening for COZ215-238-240- 242>251. High Wind Warning until 5 PM MST this afternoon for COZ038- 042>051.
