A warm front lifted north across East Texas and North Louisiana to along the Arkansas/Louisiana border during the afternoon hours of December 19th, focusing showers a large area of rain north of this boundary over portions of extreme Northeast Texas, Southeast Oklahoma, and Southwest Arkansas. Meanwhile, much warmer and humid air was found south of the front across Lower East Texas and Northcentral Louisiana, resulting in moderate surface instability. Meanwhile, a surface low developed during the afternoon over North Texas along a weak cold front, associated with a strong upper level trough of low pressure that progressed east across Westcentral and North Texas during the afternoon and evening. Steep lapse rates aloft enhanced instability across the warm sector south of the warm front, with adequate shear present and strong upper level forcing ahead of the trough leading to the development of stronger, more surface based showers and thunderstorms during the evening and overnight hours. These storms became severe as they moved across portions of Lower East Texas during the evening and into Northcentral Louisiana during the early morning hours on December 20th. Damaging winds destroyed a mobile home in Campti in Natchitoches Parish, with an isolated tornado touching down just southeast of Quitman in Jackson Parish.

Surface low pressure began to organize over the Colorado/Wyoming area on the evening of December 3rd. Surface winds over eastern North Dakota and the northwest quarter of Minnesota were from the east, and temperatures and dew points remained fairly mild. At midnight, temperatures for most of the area held in the 30s with dew points in the mid to upper 20s. This moist and mild air led to some of the precipitation starting out as rain and/or freezing rain on Monday morning the 4th. The precipitation would eventually change over to snow, with the most falling from Mayville, ND, up towards the Lake of the Woods region of Minnesota. In this area, roughly 6 to 11 inches of snow fell. Roosevelt, Minnesota, reported the 11 inches of snow. North winds picked up by late morning on the 4th and remained gusty until early evening, producing blizzard conditions over portions of eastern North Dakota and blizzard and winter storm conditions over most of the northwest quarter of Minnesota. Peak wind speeds ranged from 45 to 57 mph. The wind speeds started to slowly decrease Monday evening.
