Historic Snowfall Across the Gulf Coast Region of the United States (credit: This Day in Weather History)
DISCUSSION: Over the past few days, a weak storm system began developing across portions of the Southeastern United States. The combination of very persistent as well as deep cold air facilitated a good portion of the precipitation which was generated by this particular low-pressure system to fall as snow. Thus, many places across the SE United States bore witness to their first accumulating snowfall event in many years in most cases. During the particular snowfall event captured in the footage above from Shreveport, Louisiana, temperatures hovered in the lower 20's F with dew point values hovering between 10 and 15 F. Thus, there is no question that this was an unusual turn of events, but certainly not out of the realm of possibility as it is historically plausible for such events to occur even in the Deep South.
