SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Thu Dec 24 2020 Valid 250100Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE EASTERN CAROLINAS INTO SOUTHEAST VIRGINIA... ...SUMMARY... Severe risk -- which includes potential for locally damaging winds and a few tornadoes -- continues across portions of the Carolinas and Mid-Atlantic region, and to a lesser degree southward into Florida. ...01z Update... Strong 500mb speed max appears to have translated through the base of the eastern US trough and will eject across GA into VA later tonight. Cold front associated with this feature is beginning to surge east across western NC/SC at roughly 35kt. While the majority of deep convection with lightning is observed ahead of this wind shift, will maintain severe probabilities along/ahead of the synoptic frontal zone. Given the latest trends, will continue a SLGT Risk downstream across Coastal NC/SC into southeast VA where buoyancy remains greatest in association with mid 60s surface dew points. Very strong flow just off the surface remains conducive for strong wind gusts if augmented by minimal convective contribution. Shear is also impressive across the warm sector so damaging winds and some tornado threat remain until the front moves offshore. ..Darrow.. 12/25/2020
