Two record lows in two nights
For the second day in a row, Grand Junction hit a record low temperature Monday, the thermometer dropping to 24 degrees at the Grand Junction Regional Airport, according to the National Weather Service.
The new record for Oct. 13, set at 3:28 a.m., broke the record of 28 degrees set in 1997 and marks the first freeze of the year.
Paul Frisbie, a forecaster with the National Weather Service in Grand Junction, said the region experienced the unusually low temperatures as a result of a lack wind to keep cold air from settling on the valley floor.
“Typically we have a drainage wind, but if we don’t get those drainage winds, we get pretty good … cooling,” he said.
He said the lack of clouds combined with cooler Canadian air moving down across the Rocky Mountain West also contributed to the lows.
Sunday at 5:27 a.m. the National Weather Service recorded the week’s first record low of 29 degrees, beating the record 30 degrees set Oct. 12, 1986.
