Reanalysis cross section of the mountain wave amplification during the Marshall Fire. Today's setup is less potent from a downslope wind standpoint but still worth taking seriously due to the elevated fire risk. #COwx #COfire

Time lapse of rotor clouds spinning over the Front Range foothills yesterday, produced by a trapped lee wave. #cowx #wxsky #cofrontrange #colorado #mountainwave

Cross section of the mountain wave structure overnight. The ~100 mph gusts were suggested at least 4-5 hours ahead of time by the RAP forecast model, which showed extreme amplification with similar downward velocity to the windstorm which caused the Marshall Fire in 2021.
