June 2019 weather recap: A cool and some somewhat dry June

Tuesday, July 2nd, 2019 5:26am MST

Unsettled would be a good word to sum up Thornton’s weather for June 2019. We experienced a series of troughs and fronts that kept things unsettled and suppressed temperatures. That however did not translate into a great deal of precipitation.

Cooler than normal temperatures were seen across much of the month. Even the later part of June saw some days with high temperatures only in the 60s.

It wasn’t even until the 26th of the month that Denver and Thornton recorded their first 90 degree day of the year. This was in fact the fifth latest occurrence of a 90 degree day in Denver and the latest since 1982.

Thornton’s average temperature for the month came in at 65.7 degrees. This made the month the second coolest June Thornton has recorded in 13 years. Denver saw a virtually identical average of 65.6 degrees. Both readings were below the long term Denver average for June of 67.4 degrees.

Temperatures in Thornton ranged from a high of 98.5 degrees of the 28th of the month down to a low of 40.7 degrees on the morning of the 10th. Denver’s highest reading of 96 degrees came on the 29th and its coolest of 42 degrees on the 10th.

Denver averages 1.98 inches of precipitation during the month of June. This year, Thornton fell short of the mark while Denver exceeded it. Here in Thornton we tallied 1.51 inches while Denver saw 2.24 inches.
