MYRTLE BEACH, S.C. (WMBF) - A powerful cold front will blow through the area on Sunday providing a dramatic return to winter.

Near-record warmth will continue through the New Years holiday with daytime temperatures surging into the middle and upper 70s. The warmth will continue on Sunday but will come to an abrupt end as a very strong cold front moves through the Carolinas.

This cold front will bring a variety of changeable weather from Sunday through Monday.

So far, the SPC has outlined all of the Grand Strand for a level 1 of 5 risk for seeing a few strong to severe storms. This risk could increase as we get closer to Sunday and have a better idea of how much instability the atmosphere will have to work with.

DRAMATIC DROP

Temperatures on Sunday will soar into the lower to middle 70s once again. However, as the cold front moves through, temperatures will suddenly drop. Temperatures may drop as much as 10 to 15 degrees in an hour as the front moves through Sunday afternoon. These temperatures will continue to drop very fast through Sunday night. By Monday morning, temperatures will be in the lower to middle 30s. Gusty winds behind the front will drop Monday morning wind chills into the upper 20s.
