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 Apr 5, 3:05 PM MDT, 18 minutes earlier.
Area forecast discussion, Apr 5, 3:05 PM MDT, 18 minutes before
Area Forecast Discussion National Weather Service Denver/Boulder CO 305 PM MDT Tue Apr 5 2022 .SHORT TERM...(This evening through Wednesday) Issued at 302 PM MDT Tue Apr 5 2022 It's a busy afternoon across the forecast area with winter, fire, and wind headlines still ongoing. Across the mountains, composite radar and snow cams across the high country show snow falling over much of the higher terrain. Most of the impacts so far have been across the high mountain passes, with significant blowing snow noted over both Loveland and Cameron Pass cameras. Based on SNOTEL observations, the heaviest snow has fallen over the Park Range and in the northern Front Range, especially above 9500 feet, where up to about 10 inches of snow has already fallen. We should see at least a couple additional inches of snow tonight, especially across the I-70 mountains. Snow should gradually taper off tonight and into tomorrow morning as moisture slowly decreases. Winter Weather Advisories continue across the mountains until midnight. For the plains, both the high winds and critical fire weather conditions have been a little slower to arrive. The exception so far has been across far eastern Larimer and most of Weld county, which has seen a notable drop in Dew Point/Humidity over the past couple of hours. Humidities have fallen to 14-20% across this area, with the Crow Creek RAWS site in Weld county recently recording a 16% RH and a wind gust of 80 mph. Dry air is slowly working into the plains and will continue to do so over the next several hours. We should see gusts pick up across the rest of the plains in the next couple of hours as well as we slowly start to mix down stronger winds aloft, and High Wind Warnings/Red Flag Warnings will remain in effect until 9PM tonight. For tonight and tomorrow, the main two questions will again be the strong winds and potential for critical fire weather conditions. The upper level low responsible for our current pattern will stall out across the upper Midwest, with strong mid- level northwesterly flow continuing through the short term forecast period. Dry air will continue to work into the area through tomorrow, with dew points likely dropping to the single digits or perhaps even below zero by tomorrow afternoon. BUFKIT soundings show a deeply mixed/subsident airmass across the plains with 40-60kt 700mb flow. Guidance varies on how dry the airmass is... but all signs point to another day of High Wind Warnings and Red Flag Warnings. Additional fire weather discussion is available in the sections below. Temperatures tonight should make it to below freezing across the plains despite the downslope flow. Temperatures on Wednesday will make it into the upper 40s to low 50s across the area. .LONG TERM...(Wednesday night through Tuesday) Issued at 302 PM MDT Tue Apr 5 2022 A deep closed upper level low pressure system will drift across the Northern Great Lakes Region Wednesday night through Thursday with a strong north-northwesterly flow aloft over Colorado. Once again, their will be a strong surface pressure gradient between lower pressure over Colorado and higher pressure over the Great Plains States, This combined with plenty of subsidence and strong winds aloft will lead to breezy to windy conditions across the forecast area. The gradient shouldn't be quite as strong as it was on Wednesday; therefore, winds should be somewhat weaker. However, we could still wind gusts to around 50 mph across the far northeastern zones during the afternoon. Max temperatures are expected to on the cool side with highs in the upper 40s to mid 50s on the plains. Regardless of the cooler weather, the breezy to windy conditons combined with low relative humidity will lead elevated to critical fire weather conditions across portions of the foothills and plains. Friday into Saturday, the large upper low finally moves far enough east to allow the gradient to weaken and the winds to decrease. Max temperatures are expected to climb to above normal values during this period as an upper level ridge builds over the Rocky Mountain Region. Despite the lighter winds, fire weather conditions will remain in the elevated to critical range due to warmer temperatures and lower relative humidity. Cooler unsettled weather is expected Saturday night through Tuesday as an upper level trough of low pressure deepens over the western half of the U.S. As a result, we may see some improvement in fire weather conditions across most of the plains. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 951 AM MDT Tue Apr 5 2022 Main concerns in the TAF period will be near ILS-cigs in the early afternoon, along with continued gusty winds through the evening. Cold front has passed through the terminals this AM which has led to a few light SHRA across the metro with cigs lowering into the 050-070 range. Expect this activity won't last much past 18z. Winds should also shift back to the northwest this afternoon and strengthen, with a few gusts above 45kt possible. Winds will gradually decrease overnight with gusty winds returning Wednesday. && .FIRE WEATHER... Issued at 302 PM MDT Tue Apr 5 2022 Critical fire weather conditions are likely this afternoon and evening, especially along and northeast of a line from Longmont to Limon. Humidities should continue to dry out this afternoon as drier air slowly moves in from Wyoming. No changes to today's headlines will be needed. Overnight humidity recovery should generally be poor. While our current forecast has MaxRH values in the 30-40% range, some recent guidance keeps RH in the 20-30% range overnight. If guidance continues to trend drier tonight, we may extend the current RFW into the overnight hours. Tomorrow will bring additional fire weather concerns with very gusty winds across the plains. It should also be drier across much of the forecast area, with relative humidities falling into the 10-15% range. Wind gusts up to 65 mph will be possible across the far northeastern plains with 30-45 mph gusts likely for much of the urban corridor. While the driest and windiest conditions don't align perfectly, essentially all of the plains and Palmer Divide should see critical fire weather conditions tomorrow. Elevated to critical fire weather conditions are expected to continue Thursday through Saturday due to breezy to windy conditions and low relative humidity. An upper level trough moving into the region should bring cooler temperatures, higher humidity and possibly some precipitation beginning on Sunday and continuing into early next week. As a result, fire danger across the forecast area is expected to decrease during this period. The exception may areas stretching from the Southern Foothills eastward across southern portions of the Palmer Divide into Southern Lincoln County. && .BOU WATCHES/WARNINGS/ADVISORIES...

Thursday will still be windy, but a bit less, then Friday will be warm and dry with lighter winds. More warm, dry and breezy weather is expected into the weekend, with a chance of showers and some cooling by Sunday. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed but snowfall and high wind reports would be appreciated.
