A slow moving cold front will continue to allow numerous showers and storms to develop across the Carolinas on Thursday.
An upper level ridge is situated to our south and an upper level trough is located to our west, which is allowing a cold front to move slowly across the Carolinas. Showers and storms developed Wednesday across the Carolinas. Those showers and storms are expected to continue Wednesday night through Thursday.
With the slow moving nature of the cold front allowing for numerous showers and storms to redevelop over the same areas, flash flooding is possible across the mountains. A Flash Flood Watch has been issued for many counties across the mountains.
Outside the mountains, areas that receive numerous heavy showers and storms have the chance of flash flooding. Some of the storms could drop 2-3 inches of rain in an hour.
Most areas are expected to receive 1-2 inches of rain from Wednesday evening through Thursday evening, according to the National Weather Service. The highest rain totals are expected in the mountains and adjacent foothills.
Severe storms are also possible on Thursday due to the extremely moist environment and weak upper level energy. The SPC has a marginal risk of severe weather across central and eastern NC on Thursday. The greatest threat will be damaging wind gusts and isolated tornadoes can not be ruled out.
Showers and storms will continue into Friday as the cold front moves into the coastal plain. Early indications are that the front will move towards the coast of NC this weekend and drier air will slowly begin to move into the western and central locations.
