Another round of wintry weather tonight will get the south off to an ugly crunch for the second Monday in a row. The first batch of snow and ice is already falling across a swath of real estate from Louisiana to North Carolina, while a more threatening round of sleet and freezing rain will affect Texas and Oklahoma on Monday morning.

With temperatures as low as 15°F, it seems unusual that parts of the south saw sleet and freezing rain instead of snow on Monday.
