Spring and severe weather typically go together in the Southeast. Eastern North Carolina is not immune to severe weather events such as tornadoes, severe thunderstorms, strong winds and flooding. The period from mid-March to mid-May tends to be the most active period for severe weather in our area although it can start as early as February. Isolated severe weather events can actually occur about anytime during the year but are quite rare during the winter months. Over the past weekend we saw some strong storms with an isolated weak tornado in Greene and Wilson counties.
Severe weather is more likely to occur during the spring due to the strong contrast in temperatures and more unstable air above the surface. Also, the transtion from winter to spring usually brings strong areas of low pressure that help destabilize the atmosphere more than at other times of the year. Severe weather events become less common by summer as weather systems tend to be weaker and the jet stream lifts northward into the northern United States and southern Canada.
