The Weather Alert Day has ended.
We will still see thunderstorms through this evening, but the threat for severe weather is no longer high enough for an Alert Day.
8:00am, Friday, May 13:
A Weather Alert Day has been issued for today, May 13. An incoming cold front will help spark more widespread strong to severe thunderstorms this afternoon and evening, primarily along the coast and up into the border belt. The main hazard from storms today will be gusty straight line winds of 60+ mph, with a secondary threat of 1″+ hail. Timing will be from 1-2 PM west of I-95 to 7-8 PM along the coast.
The cold front is currently located in the Upstate as of 5 AM Friday and will be moving toward the coast all day. It will be moving into the Pee Dee as we approach our peak heating hours of the day, adding to the energy already in the atmosphere from warm temperatures and high levels of moisture. The cold front will provide the lift needed to generate thunderstorms and like yesterday, they will quickly become strong. While gusty straight line winds will be the primary hazard, other hazards are possible as well, as seen in this graphic.
Futuretrack shows some clearing behind this morning’s showers and storms, with mostly cloudy to partly sunny skies from around 9 AM to noon. As the front enters the Pee Dee early in the afternoon, showers and thunderstorms will spark west of I-95. Thunderstorms will cross I-95 between 3 and 4 PM, and should be mostly non-severe at that time. They could still contain 30-40 mph winds, but should remain below severe limits of 60 mph. The highest risk for severe storms happens between roughly 5 PM and 7-8 PM as the front gets closer to the coast and interacts with better moisture. This will be the best opportunity for severe storms containing 60+ mph winds or 1″ hail. The cold front should clear the coast by 8 PM, bringing an end to rain and thunderstorms. Heavy rain will also be a concern with any thunderstorms today with widespread totals of 0.5-1″ and locally higher amounts possible, especially near the coast.
