The Denver weather record books are being rewritten this week.

Readings at Denver International Airport overnight have far surpassed previous cold-weather marks. Just before midnight, the mercury dipped to -12 degrees, setting a new record for the coldest Nov. 12 on record in Denver, eclipsing the previous mark of -4 set in 1882.

Just before 3 a.m., the temperature plummeted to -14 degrees at DIA, shattering the record low for Nov. 13 of -3 set back in 1916.

On Wednesday, Denver also established a new low high record of 6 degrees — the coldest temperature recorded as a high on Nov. 12 since 1916 when 9 degrees was the high mark.

The weather service says an observer reported about 6:30 a.m. a -24 reading in Elba, which is about 15 miles south of Akron in Washington County. The service said that was the coldest reading they’ve seen so far Thursday.

While Thursday’s commute is expected to be less messy than earlier this week, icy bridges and overpasses remain a problem. Road crews were working overnight to mitigate any problem spots.

Denver Public Schools said they are open as normal Thursday except for DCIS Montbello and Noel Community Arts where there are ongoing heating challenges at the Montbello Campus.

Denver weather forecasters with the National Weather Service predict the temperature will climb to 17 degrees in Denver for a high on Thursday. That would be warmer than the record low high for Nov. 13 of 12 degrees set in 1959.

Friday should feel balmy by comparison, as temperatures are expected to climb above freezing for the first time since Monday, with a forecasted high of 41 degrees.
