The month of April lacked much in the way of drama for northeastern Colorado. Overall temperatures were warmer than normal and precipitation and snow were lacking a bit.
April started out on the cool side and brought the first snow of the month on the 3rd. By the 8th temperatures had rebounded and we enjoyed a five-day stretch of high temps in the 70s.
A storm system and cold front cooled things down on the 13th and we saw a couple of days of light snowfall. As always the weather bounced back and Thornton recorded its first 80+ degree day of the year on the 18th.
The final four days of the month saw things turn cool again. Some light rain was seen but the bigger story was a period of unusually windy conditions.
Denver’s average April temperature is 47.4 degrees (1981 – 2010). For April 2014, the average temperature in Thornton was more than two degrees higher at 49.6 degrees. Out at Denver International Airport, the average came in a bit cooler at 49.0 degrees.
Temperatures in Thornton ranged from a high of 81.3 degrees on the 18th down to a low of 17.6 degrees on the 14th. DIA saw its warmest reading of 80 degrees on the 22nd and its coldest of 18 degrees on the 14th.
Low temperatures dropped below freezing on 11 days in Thornton. No readings below zero were recorded.
