Overall, February was pretty close to normal, but it took a winding road to get to normal. Temperatures overall came out right about normal, with high temperatures slightly warmer than normal and lows right at average. Snowfall was slightly above normal as several of the snowstorms occurred with very cold temperatures and high snow/water ratios.
The first week of February was mild and dry with temperatures peaking about 10-15 degrees above normal on the 4th and 5th as highs reached the mid-50s. This also helped melt some of the snowpack that had built up during January. This warmth was interrupted by a series of cold fronts that affected the area starting on the 6th.
The first push of cooler air came through without any moisture, as the snow stayed in the mountains. Temperatures dropped to normal on the 6th and 7th. As the system departed, the back side of the storm swung through and produced snow and wind from the evening of the 8th through the morning of the 9th. Some decent snowfall rates occurred as well, with several inches accumulating in about two hours just before midnight on the 8th. Temperatures were cold behind the system with highs only reaching the low to mid-20s. Fresh snow on the ground and clear skies also made for efficient radiational cooling, and lows dipped just below zero on the morning of the 10th.
High pressure built in behind this system and brought in mild air from the west/southwest. Temperatures responded, jumping from the upper 30s on the 10th to the mid-50s on the 11th. Mild conditions stuck around through the next couple days as the west/southwest flow kicked in ahead of the next approaching storm system.
This next storm had more moisture to work with and again another shot of Arctic air, all just in time for Valentine’s Day. Snow started to fall by late afternoon on the 14th and continued through the 15th. During the storm, 4-8 inches of snow arrived along with chilly temperatures. Highs only reached the teens on the 15th and dipped below zero again on the morning of the 16th. This storm also had a lot of wind, so significant blowing and drifting occurred, making for some tough driving conditions at times.
Just like earlier in the month, mild conditions quickly returned, with sunshine and high pressure building in from the west/southwest. This allowed temperatures to jump back above normal from the 18th through the 21st. Highs again peaked in the low to mid-50s during the period. However, the good snowpack helped to temper highs from reaching their full potential.
These mild conditions were again interrupted by the final shot of cold air for the month, and this was the coldest yet. A strong push of Arctic air moved in during the early morning of the 22nd, accompanied by a strong cold front, gusty winds, fog, and flurries. Cold air continued to deepen through the morning with snow starting to fall as well. The cold air resulted in light and fluffy accumulations of 3-6 inches with plenty of blowing snow off and on during the 22nd and 23rd. Temperatures tumbled to the singled digits during the day on the 22nd and well below zero that night and the morning of the 23rd. But the Arctic air was shallow and began to drain from the higher elevations of the Palmer Divide during on the 24th. This allowed us to hit the low 40s that afternoon while lower elevations of the plains only reached the teens and 20s.
The remainder of the month again saw a return to mild conditions along with gusty winds at times. Conditions were dry for the last week of the month, with each day seeing average to above average temperatures. These gusty winds along with the stronger late-February sunshine also did a lot of work to melt our snowpack. But don’t get too excited, the next month is our snowiest time of the year.
A look ahead
March is known for a wide range of weather conditions in the region. We can see 70° temperatures one afternoon and blizzard conditions the next. Many of us remember the blizzard of March 2003 when we received 30-50 inches of snowfall that shut down the region. However, snow that does fall begins to melt quickly this time of the year, providing beneficial moisture for our plants as we head into spring.
