A cold front will be moving southward down the Front Range Saturday morning. Light snow is likely to develop behind the front and end before Sunday morning in most areas except maybe down near the New Mexico border. There may be a few short periods of moderate intensity snow.
Accumulation: generally 1-3 inches for the Cheyenne to Colorado Springs corridor, but some local areas of 3-5 inches are possible in and near the foothills. This time around the mountain areas near and west of the continental divide are getting snow too, with many mountain areas likely to get more than 6 inches beginning this evening.
Cold: Saturday afternoon is likely to drop into the teens and Sunday’s temperatures are likely stay in the 20s. Sunday and Monday mornings are likely to be in the 0-10 range with some high elevation valleys going below zero.
And now, for the climate enthusiasts… Denver’s record low on Thursday of -14 and Boulder’s record of -11 were both historic and the earliest it had ever been so cold. But observations can be tricky. Denver’s records have only been at DIA since 1996 and its previous locations (Stapleton, and downtown before that) tend to run warmer than DIA on calm, snow-covered nights. Boulder’s official climate station was established in 1990. The pre-1990 record in Boulder was often in non-standard exposure, like rooftops, which introduces a warm bias, especially on very cold nights. For that reason, neither of these locations are suitable for detailed studies of temperature trend. But one thing is for sure, we are having a historic November cold wave.
