The coldest month on record in Oklahoma City, and much of Oklahoma for that matter, dates back to January, 1930. The month started fairly mild with highs in the 50s and 60s. Then, the bottom dropped out as an arctic front blasted through the area on the 6th. The bitterly cold air was then reinforced by even colder air several times throughout the month. In fact, the low temperatures in Oklahoma City would dip below zero five times over a two-week span during the middle of the month. The coldest temperatures over the area were seen on the mornings of the 17th and 18th, when the mercury in Oklahoma City plunged to 9 degrees below zero. This is warm compared to the incredibly cold readings in northeast Oklahoma, where Watts recorded a low of minus 27 degrees on the morning of the 18th.
