We then saw five days of dry conditions with temperatures warming back up into the 70s.\u00a0 On the 10th the next system arrived and rain was recorded on four of the next five days in Thornton.\u00a0 Cooler than normal temperatures were notable during the period and lasted for the next eight days.<\/p>\n
On the 18th another shot winter-like weather arrived and Thornton saw its biggest snowfall yet of the season: 2.4 inches.\u00a0 Out at the airport, Denver recorded 1.4 inches.<\/p>\n
The next nine days from the 19th to the 27th were largely pleasant days but with light rain on two days during that time.\u00a0 On the 28th another cold front and storm system moved in and chilly temperatures returned.\u00a0 Thornton recorded a dusting of snow on the 30th.<\/p>\n
