The latter half of the month warmed up with above normal mercury readings being seen on all but the last two days of the October.\u00a0 That same stretch of mild days also was one in which we saw no precipitation.<\/p>\n
While the overall warm end of the month helped, we still saw overall monthly temperature readings well below normal.<\/p>\n
Thornton\u2019s average monthly temperature came in at 47.0 degrees. This is in comparison to Denver\u2019s long term October average of 50.9 degrees, a near 4 degree difference.\u00a0 Out at Denver International Airport where the Mile High City\u2019s official readings are taken, it was a bit warmer with an average for the month of 49.2 degrees.<\/p>\n
Here, we ranged from a high of 85.7 degrees on the 3rd<\/sup> down to a low of 18.1 degrees on the morning of the 15th<\/sup>. Denver saw a max of 86 degrees and a low of 18 degrees, each on the same days as our max and min.<\/p>\n
Denver set two temperature records during the month.\u00a0 The high temperature of only 27 degrees on the 14th<\/sup> set a new record low maximum for the date. This easily bested the old record of 36 degrees set in 1969. A record low temperature reading of 18 degrees on the 15th<\/sup> topped the previous record low for the date of 20 degrees set in 1970.<\/p>\n
In terms of precipitation, Thornton recorded 1.01 inches between rain and snow melt.\u00a0 Denver was very similar with a total of 0.99 inches.\u00a0 Both measurements were close to the long term Denver average of 1.02 inches for the month.<\/p>\n
Thornton saw a relatively minimal 2.8 inches of snowfall, all on the 14th<\/sup>. Denver recorded a bit more of the white stuff with 3.2 inches. Both were short of the October average of 4.0 inches.<\/p>\n
