Snow amounts have been reduced slightly across the board with lower-end solutions now appearing more likely as our pair of storms aren't phasing together well.
Nonetheless, winter returns to the Front Range today with light snow on-and-off from mid-morning into late Thursday night #COwx

⚠️🔥RED FLAG WARNING TUESDAY...
...for Boulder and the western suburbs of Denver where a pesky mountain wave will keep winds blasting out of the west. Gusts of 30-50 MPH will overlap humidity values of 12-18%. Any ignitions will rapidly spread eastward. No sparks/flames! #cowx #colorado #denver
