Certainly when you look back on February 2020, you probably will remember it as being cold and snowy. That indeed is true, as the numbers show, however that really only pertained to the first half of the month. The latter part was far more on par with what we expect to see.
The month did start out quite warm as we saw temperature readings well above normal on the first and second. The third, however, brought about significant changes and an end to the warmth that had carried over from January.
Several storm systems moved through over the next 10 days, bringing significantly colder temperatures and regular doses of snow. Indeed, 8 of the first 12 days of the month brought measurable snowfall. Into the third week of the month it appeared we were on pace for one of the coldest Februarys on record.
Things changed again on the 21st and five of the last nine days of the month brought warmer than normal temperatures. This was enough to drive up our average temperature which, while it did come in well below normal, was not in record-setting territory.
Thornton’s average temperature for the month came in at 29.9 degrees. This was a good ways below Denver’s long term average for February of 32.5 degrees. Out at Denver International Airport where the Mile High City’s official measurements are taken, it actually was colder with an average of 28.1 degrees.
Our temperatures ranged from a high of 73.7 degrees on the 2nd down to a low of -2.2 degrees on the morning of the 5th. Out at DIA, they saw their warmest and coldest temperatures of 74 degrees and -5 degrees on the same dates.
Precipitation came in well above the Denver average for the month of 0.37 inches. Thornton recorded 1.09 inches while Denver measured 0.88 inches.
Snow was of course notable for the first half of the month and drove the monthly totals. On average, Denver receives 5.7 inches in February. Thornton far surpassed that with 22.1 inches and Denver did as well with 16.5 inches of the white stuff.
