Weather and Climate Conditions
The Coastal Plain area demonstrates a striking contrast between summer and winter. During the summer months temperatures are relatively warm (40 degrees) and daylight is continuous. During the winter months temperatures drop well below O degrees and blowing snow fills in valleys and swales, resulting in the appearance of a vast, white wasteland.
