A strong arctic cold front moved into northeastern Oklahoma by sunrise on the 29th and through southeastern Oklahoma during the evening of the 29th. Precipitation developed behind the front as warm, moist air was drawn northward above the shallow cold air near the ground.
The precipitation changed to freezing rain north of Interstate 44 by the evening of the 29th and then began mixing with some sleet northwest of a Siloam Springs to McAlester line by sunrise on the 30th. The mixture continued into the morning hours of the 30th with up to two inches of sleet occurring in some locations before the precipitation changed over to snow across the entire region during the afternoon. Heavy snow fell over a large portion of the area with up to 15 inches in the heaviest swath across portions of Osage and Washington Counties.
The combination of freezing rain, sleet, and heavy snowfall through the duration of this event resulted in a crippling winter event. The Will Rogers, Cimarron, and Turner Turnpikes were closed for up to nine hours during the heaviest precipitation. Many flights into and out of the Tulsa International Airport were canceled during this storm. Sporadic power outages were reported during the storm across the region. In Ottawa County, the roof of a boat manufacturing facility collapsed due to the weight of the snow destroying 40 boats worth more than $1 million.
