The local office's own words before the first event, 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 the first event at Nov 4, 6:27 PM MST, 4 hours 33 minutes earlier.
Area Forecast Discussion National Weather Service Denver/Boulder CO 727 PM MDT Fri Nov 4 2022 .UPDATE... Issued at 723 PM MDT Fri Nov 4 2022 Have decided to expand the High Wind Warning for the mtn areas of zone 33 and zone 34. Cross-sections show wind gusts later tonight into Saturday could reach the 80-90 mph range as cross-barrier flow increases to 60-70 kt. && .SHORT TERM...(This evening through Saturday) Issued at 121 PM MDT Fri Nov 4 2022 Main concern will be the potential for a high wind event tonight and Saturday for the Front Range foothills. Colorado will transition into a subsident yet strong northwest flow pattern across Northern Colorado tonight. There is a strong 150kt jet streak which will set up just north of Colorado on Saturday. Cross sections showing 60-75kt cross barrier flow developing later tonight and Saturday morning. High resolution models from HRRR/RAP showing peak wind gusts ranging from 70-80kt along with tightening surface gradients close to 15mb from GJT to Den. In addition, expect strong low level warming and sharp inversion developing between 650-700mb close to midnight tonight. The negative factor against high winds is the amount of increasing moisture moving into the mountains tonight and Saturday with some orographic snowfall developing. If deep enough this may deamplify the mountain wave somewhat. There is a fair amount of shear aloft give proximity of the jet but feel there is enough parameters going forward to issue a high wind warning for the foothills. Best chance for the strongest winds will be from 09z tonight through 20z on Saturday before decreasing late afternoon and evening. As for the rest of the mountains, will see increasing moisture tonight in warm advection pattern. Moisture depth will remain relatively shallow, below 550mb. Lower lapse rates will keep snow accumulations mainly in the 1-3 inch range, but with the higher amounts over the Park Range and Rabbit Ears pass region. Lesser snowfall further south over the mountains in the more subsident portion of the jet. Will be issuing a winter weather advisory for zone 31 for rather persistent snowfall through the weekend along with some strong winds. Across lower elevations, considerable warmer temperatures are expected for Saturday given the strong downslope winds and low level warming expected. Given the strong surface gradient across the state, expect gusty westerly winds to spill out of the foothills and across the plains during the day on Saturday as well as further north along our border areas. .LONG TERM...(Saturday night through Friday) Issued at 121 PM MDT Fri Nov 4 2022 Strong mountain winds will diminish Saturday night as the stable layer lifts and cross-barrier flow at the ridgetop weakens slightly. Still, the HREF suggests gusts up to 55 mph will remain possible overnight, mainly contained to the higher elevations of the Front Range. Meanwhile, moisture west of the divide will increase again, with orographic snow redeveloping overnight across the mountains, especially north of I-70. There isn't any QG support to speak of, and the jet positioning is relatively unfavorable as well. Thus, most of the snow should be confined to the favorable slopes of the Park Range and Medicine Bow mountains. Though rates won't be particularly impressive, the long duration of favorable orographic flow will be enough for advisory level snowfall amounts over the Park Range where a Winter Weather Advisory will be in effect until Sunday evening. Orographic snow will continue across the aforementioned mountains through most of Sunday with zonal flow aloft continuing. It will be a bit cooler across the plains Sunday with highs only reaching the 50s. The upper level flow will turn more southwesterly as a strong upper level low moves into the Pacific Northwest. This should lead to warmer and drier temperatures for the first half of the week. Moisture will try to work back into the mountains by Wednesday, and the trough axis should pass through by Thursday, ushering in much cooler temperatures for the end of the week into next weekend. && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 516 PM MDT Fri Nov 4 2022 VFR conditions tonight into Saturday. Winds will be WSW early this evening but may trend towards more SSW by 06z. After 12z Sat expect a more WSW component which will become more westerly by 18z with gusts up to 30 mph possible in the aftn. && .BOU WATCHES/WARNINGS/ADVISORIES...

This hazardous weather outlook is for northeast and north central Colorado. .DAY ONE...Today and Tonight Expect scattered snow showers across the higher mountains but little if any accumulation is expected today. Snow showers will increase again over the higher mountains tonight, especially over the northern border areas. Accumulations of 1 to 3 inches are expected by Saturday morning, with the heavier amounts near the northern border. Winds will increase over the ridges and east slopes late this tonight. Winds of 25 to 40 mph will become common above timberline and in the higher and more wind prone foothills locations. Gusts up to 75 mph are possible late tonight. Blowing and drifting snow may be a problem in exposed higher areas. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Expect persistent windy conditions over the mountains, foothills and immediate plains to persist through Saturday, with peak gusts of 70 to 80 mph possible and areas of blowing snow. There will be scattered snow showers in the mountains off and on through Sunday with minimal accumulations. Early next week, elevated fire weather conditions are possible on parts of the eastern plains as dry and breezy conditions develop. .SPOTTER INFORMATION STATEMENT... Snowfall reports from spotters will be appreciated.
