We're tracking a threat of snow and winter weather in the Carolinas for Thursday and Friday morning: Rain midday Thursday could turn to snow, which is expected to freeze overnight into Friday. Snow accumulations are expected across much of North Carolina.

Plus we're joined by Dr. Lynn McMurdie. She is the lead investigator on the NASA IMPACTS project, an initiative that is chasing storm storms using planes, weather balloons, and remote sensing equipment to better understand winter storm intensity.  Their goal is to collect data and understanding that lead to more accurate winter storm forecasts.
