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 Pueblo, CO wrote its last area forecast discussion before this red flag warning went out at Mar 29, 3:42 AM MDT, 1 hour 45 minutes earlier.
Area forecast discussion, Mar 29, 3:42 AM MDT, 1 hour 45 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 342 AM MDT Wed Mar 29 2023 .SHORT TERM...(Today and tonight) Issued at 342 AM MDT Wed Mar 29 2023 Key messages: 1) Strong and gusty winds later in the afternoon, along with lower relative humidity values, will result in some spotty critical fire weather conditions over portions of the plains. 2) Downsloping winds will give way to much warmer temperatures over the plains, with even a few locations above the seasonal average. 3) Some locations along the banana belt and over the southern plains will see relatively warmer temperatures for lows tonight due to gusty winds continuing through the night. Detailed discussion: Today... Weak ridging over the region will be propagating eastward as a trough upstream over the western states continues to advance closer. This will allow for a tightening of the surface pressure gradient and increase of southwesterly winds by later in the afternoon over most of the higher terrain and along the southern I-25 corridor. Given that there will be some drier air being advected in from the southwest, along with downsloping and adiabatically warming winds, relative humidity will drop with strong enough winds in place to reach critical fire weather conditions for a few hours over portions of the plains. There will be a relatively cooler airmass with an associated boundary over the eastern plains that will determine how far the southwesterly winds advance across the plains. This has made it tricky to forecast high temperatures and the extent of the fire weather concerns based on the position of this boundary and how far it advances westward. Some of the highest resolution models such as the HRRR keep the boundary right along the northern I- 25 corridor and then extends back through the northeast portion of Pueblo County and then down through lower Otero and Baca counties. This model has a bias which does tend to overmix, and the NAMNest pushes the boundary further west and limits how far the southwest wind component penetrates. There looks to also be a lee-side meso-low which shows up in both models that forms over Pueblo Country during the late part of the afternoon. That being said, there is higher confidence that the strong and gusty southwesterly winds will remain confined to the southern I-25 corridor, and not much further eastward than Huerfano and Las Animas counties. Depending on how far the colder air advances west will also dictate what the high temperatures do for the plains. If the colder air undercuts the southwesterly flow and makes it further west, it could hinder some locations from reaching their current projected high temperatures. Otherwise, because the colder airmass is relatively shallow and mixing should be sufficient, as well as a higher sun angle and only passing mid level clouds, most locations west of the Las Animas/Baca County line should warm up considerably. There could even be some locations around the southern I-25 corridor that will break to 70 degree mark, while the eastern plains remain cooler and closer to the seasonal average. Temperatures over the higher terrain will also be noticeably warmer from where they were yesterday. Tonight... Locations along the banana belt and southern plains will experience relatively warmer temperatures due to the downsloping and southwesterly winds continuing over these areas, which will keep the lower levels mixed. North and east of the boundary over the plains will become much colder due to lack of wind and more efficient radiational cooling. Expect these temperatures to fall into the 20s, while the southern plains will struggle to get below 40 degrees. Winds will continue to increase out of the southwest over the higher terrain through the night, with temperatures only dropping into the teens and 20s for most locations, and even some lower 30s for the mid and upper Arkansas River Valley. -Stewey .LONG TERM...(Thursday through Tuesday) Issued at 342 AM MDT Wed Mar 29 2023 Key messages: 1) Very critical fire weather conditions Thursday for the I25 corridor and eastern plains. 2) Critical fire weather conditions likely Friday. .Thursday...Strong upper trough moves eastward across the Great Basin. Southwest flow aloft strengthen with 700mb winds in the 35 to 50 knot range. With a deepening lee trough, windy to very windy conditions will develop over the region. Humidities on the plains and I25 corridor will lower into the single digits during the day resulting in very critical fire weather conditions. Along with surrounding offices, upgraded the fire weather watch to a red flag warning. The warning was extended to 8PM given the lower humidities will linger on the plains, especially near the Kansas border. This will be a higher end fire weather day so extra caution is advised. The San Luis Valley was not included in the red flag warning as humidities will stay around 20 percent. Did not touch the high wind watch. Winds in the grids approach or just exceed high wind criteria mainly over the southeast mountains and nearby plains. Despite the strong southwest flow aloft, moisture will be fairly limited and snowfall amounts for the eastern San Juans stay just below advisory criteria. .Friday...The strong trough will move east of the state with dry northwest flow behind the trough. Main concern will be critical fire weather conditions along the I25 corridor and much of the eastern plains. Humidities in the San Luis Valley are approaching critical fire weather values and will have to watch for fire weather highlights. The northwest flow will be relatively dry and expect sub advisory snow amounts in the mountains of Lake and Chaffee Counties. .Saturday and Sunday...Upper ridge builds over the region with dry and mild weather. Will have to watch for critical fire weather conditions over the I25 corridor and eastern plains. Daytime humidities are forecast to be near of below critical values, but winds may not be sufficiently strong given the upper ridge aloft. .Monday and Tuesday...Upper trough approaches from the west on Monday. Models and ensemble means suggest some snow will move into the mountains later on Monday. This setup would be favorable for critical fire weather conditions on the plains given the low humidities and potential for increased winds. The bulk of the ensembles have the system moving to the north of the region. This would bring a chance for some snow to Continental Divide region. Like the past few systems, the ensemble charts suggest the system may be slow enough and far enough south to get some precipitation into the northern portions of the I25 corridor and portions of the eastern mountains.--PGW-- && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 342 AM MDT Wed Mar 29 2023 VFR conditions are expected to prevail for all TAF sites (KALS, KCOS, and KPUB) throughout the forecast period.
