For the second consecutive year, temperatures were below normal and precipitation was above normal in 2023. This continued the trend around the Palmer Divide so far this winter and hopefully will continue into spring. The month started off warmer than normal and ended warmer than normal, but most days in between were cold and unsettled.
After a quiet first three days of the month, a period of cool and snowy conditions moved in. This produced measurable snowfall each day from the 4th through the 8th. During the period snow wasn’t continuous but off and on each day, accumulating 6-10 inches for most of us.
In the middle of the month, a strong blast of Arctic air invaded the region and most of the country. High temperatures reached 40F on the afternoon of the 9th, but that was the last time we reached above freezing until noon on the 16th. This is an extremely long time frame for us as even in very cold outbreaks we usually scour out the cold air within a few days and westerly, warming winds kick in.
However, this time, the cold air mass was deeper than normal and had a couple of reinforcing surges. Westerly winds never materialized until the end of the event. Temperatures reached the teens and 20 below zero on five consecutive nights from the 13th through the 18th. During the period, snowfall wasn’t heavy, partly because the air was so cold, but we managed to pick up 2-4 inches over the period.
Mild conditions moved in quickly behind the departing cold air, with highs reaching into the mid- and upper 40s on the 17th and 18th. A quick shot of cold air and light snow moved in overnight on the 18th and kept temperatures cold on the 20th with highs in the low 20s. Once again, mild conditions moved in quickly, with high temperatures 30 degrees warmer than the day before, hitting the low 50s. Temperatures remained slightly warmer than normal over the next week, with highs in the 40s each afternoon from the 21st through the 25th.
The final storm of the month began to affect the region during the early evening of the 25th. However, this storm was of Pacific Ocean origins, and this meant relatively mild conditions. Temperatures were only slightly below freezing during the event, producing heavy, wet snowfall that felt more like April than January. The relatively warmer air mass was also able to hold higher levels of moisture, and this resulted in some quick accumulations, with the storm producing 4-7 inches from the evening of the 25th through the morning of the 26th. After this system departed, mild temperatures returned to the region to end the month. Highs moved through the 40s on the 27th to the 50s from the 28th through the 31st, a bit of a January thaw before we head into our snowiest months of winter.
A look ahead
February is often a transition month as we move from the dry and cold conditions in December and January toward relatively warmer and wetter conditions of March and April. Precipitation averages around an inch with just over 20 inches of snow expected and average high temperatures in the 30s. It can get very cold in February with Arctic air making brief pushes into the region. However, days begin to get a little longer, which leads to some nice, sunny days, and the snow that does fall begins to melt faster.
