Thornton’s month of November saw us get a real taste of what is to come for the next few months. Temperatures cooled considerably and we saw a decent bit of snow although not as much as normal.
The first five days of the month started out relatively mild but then we saw a series of systems interrupt the calm. Temperatures turned colder and on the 11th and 12th we received a nice little snowfall. We briefly warmed up then saw some light rain on the 18th and 19th and then once again warmed back up. The month closed out with a chilly day and some light snow.
Thornton saw an overall average temperature for the month of 36.8 degrees. This was a good bit colder than Denver’s long term average for the month of 38.3 degrees. Out at DIA where Denver’s official measurements are taken, it was a good bit warmer with an average of 37.8 degrees.
Temperatures for us ranged from a high of 64.7 degrees on the 2nd of the month down to a cold low of 15.7 degrees on the morning of the 26th. Denver’s high of 65 degrees on the 2nd matched ours but their coldest reading of 10 on the 12th was notably colder than our lowest reading.
November’s long term precipitation average in Denver is 0.61 inches. Thornton managed about half that in our bucket with 0.31 inches with Denver close to us at 0.35 inches.
Snowfall was respectable but not notable. Thornton recorded 6.3 inches of the white stuff while Denver, as usual, lagged with 4.5 inches. Both measurements were below Denver’s long term November average of 8.7 inches.
