What forecasters said that day
The local office's own words before this high wind 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 high wind warning went out at Apr 6, 11:10 AM MDT, 3 hours 19 minutes earlier.
Area forecast discussion, Apr 6, 11:10 AM MDT, 3 hours 19 minutes before
Area Forecast Discussion National Weather Service Denver/Boulder CO 1110 AM MDT Wed Apr 6 2022 .UPDATE... Issued at 1100 AM MDT Wed Apr 6 2022 It's dry and windy across the plains this morning. A few changes have been made to the grids with the morning update. The main change was to lower afternoon humidity values as many locations in the Denver metro are already seeing critical fire weather conditions develop. Dew points have been several degrees lower than most blended guidance and we've made some manual adjustments to at least get closer to reality. The second change was to add in additional blowing dust into the far northeastern corner of the state. Webcams and surface observations have indicated some areas of reduced visibility due to blowing dust. CIRA's DEBRA dust product also shows blowing dust has increased quite a bit over the past couple of hours. Have joined our neighbors to the east with a Blowing Dust Advisory for Sedgwick and Phillips counties where dust could impact travel. Otherwise, the rest of the forecast is largely on track. Gusty winds will continue through the rest of the afternoon and into the evening hours. Red Flag Warnings and High Wind Warnings remain in effect across the plains until 8 or 9PM. && .SHORT TERM...(Today and tonight) Issued at 439 AM MDT Wed Apr 6 2022 Today will be pretty similar to yesterday as the system over the Northern Plains moves east slowly. Strong northwesterly flow aloft will persist and synoptic subsidence will become strong. Forecast soundings show deep mixing to around 600 hPa, into strong mid- level winds of 40 to 60 knots. There is also still a strong pressure gradient between that system and high pressure building over the Rocky Mountains ahead of the ridge moving over the western states. We maintained our High Wind Warning an also extended the area a few zones further west, now including the northern urban corridor southeast through the plains just past the Denver metro. Continue to expect strong northwesterly winds 30 to 40 mph gusting up to 65 mph in many areas, from late morning through early evening. The airmass also remains very dry and there will be near-critical afternoon minimum humidity of 15 to 20 percent across most of the eastern plains. It will be drier closer to the foothills due to persistent downsloping winds and humidity will become critical there. We maintained our Red Flag Warning for all of our plains, also late morning through early evening. There will be decreasing moisture and snowfall, probably just a few, very light showers lingering in the mountains through the day. Cold air advection will keep temperatures cooling, with highs in the upper 40s and lower 50s across the plains and teens and 20s in the high country. The flow aloft should start to turn more northerly tonight as the system drifts to the Great Lakes and the ridge moves over the west coast. .LONG TERM...(Thursday through Tuesday) Issued at 439 AM MDT Wed Apr 6 2022 A strong, broad trough will nearly stall out and expend in size on Thursday as it encompasses the eastern two-thirds of the contiguous US. There will be a north-northwesterly jet stream on the western side of this trough that will be over Colorado. Near the surface, there will be a strong pressure gradient as well as weak cold air advection. The winds at 700 mb will be impressively strong with speeds over 60 knots across the far northeastern plains Thursday morning. With mostly sunny skies expected, there will be steep low level lapse rates that will aid in producing deep mixing within the boundary layer. This deep mixing will bring down some of the stronger winds to the surface and gusts are expected to be as high as 65 mph across the far eastern plains. Therefore, a High Wind Watch was issued for northeast Weld, eastern Elbert, and all counties east of those locations. Across the I-25 corridor and Denver metro, the pressure gradient will be weaker and the strong winds in the low to mid levels will be weaker as well. This should keep gusts below High Wind Warning criteria so no wind highlights were issued although gusts could reach up to 50 mph there. The strong gusts and dry conditions will lead to another day of critical fire weather conditions and this is discussed further in the fire weather section below. Another thing to note about the weather on Friday will be the potential for blowing dust. Considering there was blowing dust occurring on Tuesday, the soil conditions are conducive for blowing dust. The strong winds and steep low level lapse rates are great indicators that blowing dust will be an issue so it was added to the forecast across the far eastern plains. Otherwise, high temperatures will be below normal with highs in the 50s to upper 40s across the plains. The broad trough will drift eastward on Friday and the jet stream aloft will move eastward with it. Wind speeds throughout the troposphere will decrease as a ridge aloft builds in. Warm air advection will increase high temperatures above normal with the mid 60s expected in Denver. There will be sunny and dry conditions due to the subsidence from the ridge. The ridge will pass overhead Friday night and into Saturday as a trough moves into the Pacific Northwest area. Another day of warm air advection and subsident flow will increase temperatures to the mid 70s across the plains. Critical fire weather conditions are a legitimate threat as winds increase with an emerging surface low pressure center over the northern High Plains. The trough over the Pacific Northwest along with another trough over the northern Pacific Ocean will be the focus for next week. Models have come into slightly better agreement that the first trough will push a cold front through our area Saturday night into Sunday with a possible chance of precipitation occurring along the front. The best chance for precipitation would be in the mountains due to the westerly, upslope flow. Global models and their ensembles are showing the secondary trough digging into the Desert Southwest region on Monday and it eventually will move towards our forecast area Tuesday and Wednesday. Ensemble guidance for the ECMWF and GFS indicates the Tuesday and Wednesday period will be one that needs to be monitored for a potential of an impactful weather event. There is decently high confidence that this period will see impactful snow in the mountains as all the ensemble members have snow at Berthoud Pass with an average of 10 inches of accumulation by Wednesday night. There is lower confidence in the precipitation potential for the I-25 corridor and eastern plains. Some ensemble member are very excited about the potential for snow in Denver and it wouldn't be a stretch given the likely positioning of the trough over eastern Colorado. There's not much more detail we can provide about this system at this time other than saying the potential exists for a big system. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1100 AM MDT Wed Apr 6 2022 VFR conditions through the TAF period. Gusty northwest winds are likely to continue into the evening hours before weakening overnight. Winds should pick up again tomorrow with a slightly more northerly component to the winds. Some blowing dust will likely be in the vicinity of DEN through the afternoon. Can't rule out brief visby reductions there through roughly 02z or so but low confidence in any impacts. && .FIRE WEATHER... Issued at 439 AM MDT Wed Apr 6 2022 Strong northwesterly winds 30 to 40 mph gusting up to 65 mph in many areas will be coincident with near-critical humidity of 15 to 20 percent across the eastern plains and critical humidity of 10 to 15 percent on the plains closer the foothills, from late morning through early evening. We maintained our Red Flag Warning for all of our plains, also late morning through early evening. The strong winds will be the main factor increasing fire danger on Thursday with gusts up to 65 mph expected over the far eastern plains. There will be a bit of a direct relationship between wind speeds and minimum relative humidity since areas with less wind will be able to have warmer temperatures and lower relative humidity. The I-25 corridor will have relative humidity drop to 11-15 percent with gusts up to 50 mph. The far eastern plains will have gusts up to 65 mph with minimum relative humidity between 15-20 percent. If a fire were to start, it would likely spread rapidly due to the strong wind gusts even though the relative humidity isn't below the red flag threshold of 15 percent. Therefore, a Red Flag Warning was issued for the entire plains from the city of Boulder to the Kansas and Nebraska borders. There will be pockets of elevated fire weather conditions on Friday across the plains and critical fire weather conditions may return on Saturday as winds pick up ahead on an incoming system while relative humidity drops to the low teens. && .BOU WATCHES/WARNINGS/ADVISORIES... High Wind Warning until 8 PM MDT this evening for COZ038-042>051. Blowing Dust Advisory until 6 PM MDT this evening for COZ050-051. Red Flag Warning until 9 PM MDT this evening for COZ238>251. Red Flag Warning from 11 AM to 8 PM MDT Thursday for COZ238>251.

This hazardous weather outlook is for northeast and north central Colorado. .DAY ONE...Today and Tonight Strong northwesterly winds gusting up to 65 mph will continue across the far eastern plains, with gusts up to 50 mph possible for the Denver Metro and Palmer Divide. Blowing dust will also be possible across far northeastern Colorado with these strong winds. Critical fire weather conditions are likely to continue this afternoon and evening across the lower elevations. Avoid any activities that could create a spark. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Strong winds are expected to continue on Thursday with gusts up to 65 mph across the far eastern plains. The strong winds combined with the minimum relative humidity in the teens, will create critical fire weather conditions across the plains. Winds will weaken on Friday with dry conditions and warming temperatures. Critical fire weather conditions are possible on Saturday across the plains with very dry conditions and breezy winds. A potentially significant storm system will impact our forecast area early next week with heavy snowfall likely in the mountains, and some potential for heavy snow over the plains as well. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed but snowfall and high wind reports would be appreciated.
