Cold fronts Monday night and Wednesday night will send the temperatures to autumn levels for a change. We are not expecting significant widespread precipitation to quench the extreme dryness of the Front Range, but some spotty precip is probable Wednesday night or Thursday.
The first front is bringing a few areas of showers to the mountains right now, but the amounts are not that great, and little or no precipitation is expected along the Front Range and northeastern plains.
The second cold front Wednesday night maybe associated with more north-northeast winds, so clouds and some areas of mainly light precipitation are more likely. Mountain areas will probably see some light snow accumulation. For the Front Range urban corridor the air mass could get cold enough to mix in some snow, but only if it rains long enough to help cool the lower atmosphere, and it’s not the middle of the day. Since the confidence regarding the precipitation is still low, let’s say the first small possibility of snow is Thursday, but it’s not likely.
By Friday morning there may be widespread frost in the lower elevations of the Front Range and northeastern Colorado. That would be pretty close to the climatological average if it happens.
