A major winter storm produced a variety of precipitation types. The precipitation began as a period of freezing rain, which coated most elevated surfaces with one-tenth to one-quarter inch of ice. As colder air filtered southward, the freezing rain changed to sleet and then snow. Thunder and lightning accompanied bursts of heavy  sleet and freezing rain. The duration and intensity of the snow was highest in far southern sections. Along and south of a line from Carbondale and Marion to Harrisburg, three to four inches of snow fell on top of a layer of sleet about an inch thick. The snow fell heavily at times, reducing visibility to one-half mile or less. The lowest amounts were along and north of Interstate 64, where an inch or two of snow and sleet fell. The following are some specific reports: At Carbondale, two inches of snow fell on top of 1.5 inches of sleet. At Mount Vernon, one inch of snow fell on one inch of sleet. The messy mixture created very dangerous travel conditions. Very cold temperatures in the wake of the storm system hampered road crews by rendering some road chemicals ineffective. Low temperatures were around 10 degrees above zero on both the 3rd and 4th of March. Gusty winds produced low wind chills from zero to 10 below, along with some drifting of the sleet and snow. Peak wind gusts were around 30 mph during the storm. The stage for this winter storm was set by an Arctic cold front that moved southeast across the region, followed by a surge of Arctic air on gusty north winds. A low pressure system developed along the front over the Gulf coast states, then moved northeast to the southern Appalachian Mountains. A 500 mb shortwave trough moved east from the southern Plains, passing across the Lower Mississippi Valley. Moisture associated with the shortwave trough and the surface low overspread the Arctic air, resulting in widespread heavy precipitation.
