A massive winter storm pounded Oklahoma on these days. Up to 21 inches of snow was reported in localized areas in the northeast. Tulsa recorded 13.2 inches of snow on the first while Oklahoma City had 12.1 inches, both of these amounts are record one-day snowfall totals for those cities. Reports of 6-12 inches were widespread across the state. Up to 2 inches of sleet fell in southern Oklahoma before the changeover to snow. Thunder was reported with the heaviest precipitation. Winds gusted over 50 mph over much of the state, combining with the snow to create true blizzard conditions. The strong winds also caused drifting snow, paralyzing travel and burying some locations in the north under 5-10 feet of snow.
The Kenton Mesonet site reported a low temperature of -6 °F.
A cold front brought freezing rain and snow to the northwest, which later turned to all snow behind the front. Snowfall amounts ranged from a trace to 6 inches in Ellis, Harper, Woods, and Woodward counties.
The state’s high temperature for the month, 87 degrees, occurred at Altus (Jackson) on the 2nd, setting a new statewide record high for that date. The previous high temperature for February 2nd was 86 degrees and was measured at two locations: El Reno in 1911 and Hollis in 1995.
Bristow and Holdenville recorded 40 °F temperature changes from the day before as a significant arctic air mass entered the state.

Amounts of 20-25 inches were widespread in the eastern portion of that band, with some areas receiving as much as 40 inches of snow.
Strong southerly winds brought warmer temperatures and warmed Mangum’s high temperature to 62°F only a few days after snow fell.

A fast-moving squall line associated with a strong arctic cold front crossed the state from west to east on the evening of the 18th into the morning of the 19th.
