The episode as NWS BOU wrote it up.

NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Apr 27, 1:53 PM MST, 48 minutes earlier.
Area Forecast Discussion National Weather Service Denver/Boulder CO 253 PM MDT Wed Apr 27 2022 .SHORT TERM...(This evening through Thursday) Issued at 253 PM MDT Wed Apr 27 2022 Short wave trough passing over Colorado will bring scattered showers and few thunderstorms this afternoon. This activity will push east of the area by early evening. Spotty light rain and gusty outflow winds will accompany the showers and storms. Most of the rainfall is expected to evaporate before reaching the ground because of the dry low levels. The 2PM temperature-dew point spread is 53F at KDEN (73/20). Subsidence behind the wave will lead to drying conditions and clearing skies for tonight. Airmass will remain on the mild side withe lows in the 35 to 45 degree range across northeast Colorado. For Thursday, southwest flow aloft will continue. The mild airmass stays in place with highs in the 70s across northeast Colorado. A weak cold front backdoors into far northeast Colorado. Behind it, dew points climb into 30s...possibly 40s by evening. Could see a weak shower over the mountain during the afternoon, otherwise it is looking like a dry day. .LONG TERM...(Thursday night through Wednesday) Issued at 253 PM MDT Wed Apr 27 2022 Thursday evening, a trough approaches from the west with an axis of instability positioning to east brushing the far northeast corner of CO. This will support chances for isolated to scattered showers/storms over the northeast plains. Model soundings show dry air in place at the surface limiting precip. potential and favoring gusty outflow winds and virga. The main trough axis and associated low pressure move across Friday with majority of the moisture staying off to the east. Upper level flow transitions to NW and synoptic subsidence gradually works into the region. Moisture with the low combined with NW flow will support orographic rain/snow showers over the higher terrain. Any accumulations will be minor with little impact. Moisture stays in place over the northeast corner Friday afternoon on the backside of the low which will promote chances for showers. The main concern will be winds and fire weather. A 700 mb jet max positions over the eastern plains behind the exiting low. With soundings showing efficient mixing and low relative humidity in place, this will promote another day of elevated to near-critical fire weather conditions. Saturday, there is a good chance for at least elevated conditions across the plains. ECMWF ensemble members continue to show good agreement for gusty winds over the plains with a weaker signal being displayed by the GEFS. There is potential for the passage of a few systems Sunday afternoon through mid-week next week bringing chances for precipitation to the mountains and portions of the plains although available moisture appears to be limited. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday night) Issued at 231 AM MDT Wed Apr 27 2022 Gusty outflow winds to 40 knots will be possible with scattered showers and few thunderstorms through about 23Z. This activity then pushes off to the east by 00Z with quiet weather expected for tonight. Southeast winds are expected to prevail once the convection moves off. Winds then slowly turn to the southwest for tonight and Thursday morning. && .FIRE WEATHER... Issued at 231 PM MDT Wed Apr 27 2022 Brief windy conditions to 50 mph will accompany the showers and thunderstorms this afternoon. This activity will move off to the east by early evening. Weak winds are then expect through tonight and Thursday morning. Southerly winds increase Thursday afternoon with gusts to around 20 mph. Relative humidity will be low over most of the plains with readings falling into the teens during the afternoon. Elevated to near-critical fire weather conditions are possible Friday over the Palmer Divide, foothills, and urban corridor with the best chances for critical conditions south of I-70. Relative humidity values ranging from 13-20 percent combined with gusts 35-45 mph in those areas. Relative humidity values are marginal over most of the areas; however, portions of the Palmer Divide and Southern Lincoln display the best potential for highlights at this time. Other areas of the plains will have slightly higher relative humidity values 20-25 percent and elevated fire weather conditions are expected. There is high confidence for at least elevated conditions across the foothills and plains Saturday. Similarly, confidence is lower in potential to hit critical conditions due to marginal relative humidity values. && .BOU WATCHES/WARNINGS/ADVISORIES...

Winds will generally be light today. However, high based showers and thunderstorms this afternoon will produce brief wind gusts of 30 to 50 mph. Very little rainfall is expected with this activity. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Thursday afternoon will be the warmest day this week with afternoon highs reaching the mid to upper 70s for parts of the plains and urban corridor. Valleys and mountains will reach the lower 50s to lower 60s. Fire weather conditions will be elevated Thursday with low relative humidity; however, winds will be on the lighter side limited potential for critical conditions. The best chance of rain showers arrives Friday afternoon mainly for the high country and the far northeastern plains near the Nebraska/Colorado border. Strong 35-45 mph wind gusts return Friday afternoon through Saturday for all areas which also may lead to fire weather concerns on the Palmer Divide and adjacent plains. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed.
