February 2014 weather recap: Much colder than normal but drier

Saturday, March 1st, 2014 1:15pm MST

Like all months in Colorado, February 2014 did have some warm periods but those were few and far between as compared to the cold we experienced.  Those cold temperatures did not translate to precipitation however.

The month started out quite cold with 9 out of the first 10 days seeing below normal temperatures.  Two of those days saw ‘high’ temperatures only in the single digits.  Seven of those 10 days stayed below freezing and four saw low temperatures below zero.

Warmer weather courtesy of downslope flow did finally arrive and most of the rest of the month was warmer than average.  Of the last 18 days of the month, only two had below normal temperatures.

Overall Thornton’s monthly average temperature for February 2014 was 28.5 degrees.  This was four degrees below Denver’s February average of 32.5 degrees.  Officially Denver’s average for the month was close to ours at 28.2 degrees.

While clearly a cold month, February 2014 failed to reach ‘top 10 coldest February’ status.  Number 10 on that list is February 1905 with an average temperature of 25.2 degrees.  The coldest February was in 1899 with an average of 17.6 degrees.

Temperatures ranged from a high of 68.3 degrees on the 16th down to a low of -12.6 degrees on the morning of the 5th.  Out at the airport, Denver saw its highest temperature of 68 degrees and its lowest of -19 degrees on the same dates.

Denver record low maximum temperatures on the 5th and 6th.  High temperatures on those days were minus 1 degree and plus 1 degree respectively.

Thornton recorded a mere 0.17 inches of precipitation in the rain bucket during the month.  Denver officially saw 0.19 inches.  Both fall well short of the February average of 0.37 inches.  While dry, it wasn’t dry enough to be one of the top 10 driest Februarys.

In terms of snowfall, Thornton measured 4.7 inches.  Denver lagged with only 3.3 inches.  Again, both were a good ways below the historical Denver average of 5.7 inches.
