December 26th Significant Severe Weather Threat

The Storm Prediction Center is forecasting another dangerous severe weather situation tomorrow, December 26th, after an already destructive day along the Gulf Coast.

We are already seeing the storm system responsible for this destruction start to ease up on the Gulf Coast and start its trek northeast. However, as it does so, another area of potentially dangerous weather will evolve along the Southeast coastline. Cities like Raleigh, Charlotte and Wilmington will be at risk for the worst of these storms.

Discussion: As the storm treks northeast, lower level winds will maintain their speed, possibly strengthening, providing a base to strong storms. Readily-available Gulf moisture and instability will flourish in the Southeast, as the warm front lifts this moisture north. A trailing cold front will kick off the event with individual cells, possibly in linear form thanks to overnight outflow boundaries and existing convection. As the day goes on, lower level winds will strengthen over the area of interest, promoting both a damaging wind and tornado threat.
