Today became the hottest November day on record in Denver as the temperature hit 81 degrees near Denver International Airport. That's more than 30 degrees above average for this time of year.

The previous record for this month was 80 degrees, a temperature reached on Nov. 8, 2006 and Nov. 16, 2016. As you can see, the new record came much later in the month.

The late-season warm stretch could break tonight with the arrival of a cold front and storm. A few inches of new snow could fall on the mountains tonight, while Denver can expect rain showers and then snow after midnight. Accumulations down here should be minimal.

The rest of the week should be dry and breezy, with temperatures jumping between about 47 and 57. The norm for this time of year is about 46 degrees.

The next chance for significant snow is this coming Sunday through Wednesday, when a storm could put a foot of snow on the southern mountains, according to Joel Gratz of OpenSnow.

Temperatures this month have been nearly 6 degrees above average, according to Brendan Heberton of Weather5280, who explains Denver weather in depth and has some guesses about the weeks ahead. The pattern could get more favorable for snow and cold, but it "may be a narrow window" for that kind of weather, he writes.

Yesterday also set a temperature record for Nov. 26 in Denver. The excessively warm temperatures, combined with high winds, could create a fire hazard, according to NWS. Climatologists and fire fighters say that this type of warm weather has extended the brush-fire "season" in Colorado.
