November was warmer than normal, the complete opposite of last year, but I’m sure most of us weren’t complaining. We did get three periods of unsettled weather that allowed our precipitation to end up right around normal, but most days between those storms were mild.
The first week of the month was mild and dry with temperatures in the 60s to low 70s. Each day saw lots of sunshine with areas of high and mid-level clouds at times. They produced some spectacular mountain wave clouds along with colorful sunrises and sunsets.
The first of three periods of unsettled weather then moved in on the 8th, with an initial frontal passage early in the morning. Clouds continued to fill in throughout the morning, with light snow beginning just before noon. Light snow continued off and on most of the day and ended just after midnight on the 9th. This system was relatively warm by November standards and therefore the heaviest snow occurred on top of the Palmer Divide with much less snowfall accumulating down around the I-25 corridor.
Dry conditions returned from the 10th through the 18th, with temperatures generally above average each day. The warmest period occurred from the 14th through the 16th, with highs well into the 60s each afternoon.
Another quick shot of cold air and snow moved in late on the 19th. Snow and some blowing snow developed that evening and continued throughout the next day. This system was colder than the previous storm and therefore produced more widespread snow across the area. Most of us accumulated 2-4 inches during the storm.
Once this storm moved out, sunshine and mild conditions returned, but only for a few days. Highs jumped into the mid-40s on the 21st, then southwesterly winds kicked in and pushed temperatures back into the mid- and upper 60s on the 22nd. But as usual, these mild temperatures were ahead of a much colder airmass. The first effects of this colder air moved in Thanksgiving morning and continued to fill in during the day. Flurries began to develop that evening as temperatures continued to fall, reaching the teens before midnight. Colder air continued to move, which meant the teens were as warm as we got on the 24th. Along with that, strong northerly winds helped to keep light snow, flurries, and blowing snow in place all day. As wind shifted out of the south, fog developed that day and evening, producing cold, windy, and snowy conditions.
Cold and windy conditions continued into the 25th as the last portion of this storm moved out of the region. This produced more light snow and blowing snow through the morning and afternoon and kept temperatures in the teens for the second day in a row before conditions finally settled down. Of course, the clearing skies and fresh snow also allowed temperatures to fall quickly that evening, dropping to the single digits by the morning of the 26th.
As with the previous two snowy periods, quiet and seasonal conditions quickly returned, and temperatures returned to normal levels to end the month with plenty of sunshine.
A look ahead
December usually is cold around the region, with daytime highs often staying below freezing and overnight lows that can drop well below zero. But we can experience a wide variety of weather, with westerly winds producing mild conditions. The month is generally dry, however, with several light, fluffy snowfalls. Gusty winds are a common nuisance during the month, especially west of I-25. The chance of a White Christmas is fairly good for the area, with some snow on the ground and, if we are lucky, fresh snowfall on Christmas Eve or Christmas Day.
