The month was one largely bereft of any true weather drama. It started out quite warm and dry and while we chilled out and got wetter for the second half, there were no significant events of note.
The first couple of weeks of March were notable for their largely warmer than normal temperatures and their lack of precipitation. It wasn’t until the 15th when we finally saw some moisture.
The latter half of the month did turn largely cooler although there was a period from the 21st to the 25th with unseasonably warm mercury readings. Beyond that, things remained cool and we received a few, minor shots of snow and rain.
In the end, the average temperatures for the month were above normal and while snowfall was less than normal, we recorded above average levels of precipitation.
The overall average temperature in Thornton for the month was 42.6 degrees. This was a good bit above Denver’s long term average for the month of 40.4 degrees. In the Mile High City at Denver International Airport where official measurements are kept, a similar average of 42.7 degrees was seen.
Temperatures in Thornton ranged from a maximum of 74.2 degrees on the 22nd down to a low of 16.6 degrees on the 7th. At DIA, the warmest reading was 73 degrees and the coldest 13 degrees, both on the same days as our warmest / coldest readings.
In terms of precipitation, Thornton saw 1.25 inches of liquid precipitation. Denver lagged us with 1.02 inches. Both measurements, however, were above the March long term average of 0.92 inches.
March is usually one of our snowier months with an average of 10.7 inches recorded during the month. We fell a long ways short of that however with Thornton seeing 6.2 inches of the white stuff and Denver only 4.8 inches.
