"Denver hit 78 degrees today, breaking a record high set in 1941. But tomorrow, we're looking at highs in the 40s and snow!", according to Denver 7 news.
The earliest recorded date for the first measurable snow of the autumn in Denver ever measured was on September 3, 1961. The latest date ever recorded in Denver was on November 21, 1934. On average, Denver's first measurable snowfall of the year takes place on October 18th. The latest first measurable snowfall in Denver in the last ten years fell on November 15, 2010, a date we have already passed.
Today, it is the evening of November 16, 2016 and it is sixty-two degrees out, just five days shy of a tie of the record.
We are forecast to having freezing temperatures tomorrow and the day after in the late afternoons and evenings, after which temperatures are supposed to warm up above freezing even at night for several more days. There is a 60% of precipitation in some combination of rain and snow tomorrow in Denver, but a much lower chance of precipitation the day after when it could also get cold enough to snow.
So, we have about 50% odds of getting a little bit of short lived snow tomorrow (still 30 days later than usual and later than any year in the last decade or more) and about 50% odds of breaking the all time record for a late first snowfall in autumn in Denver.
In another 24 hours we will find out which scenario actually happens.
