Tuesday: Another foggy start to an unseasonably warm day
Tuesday looks to start much in the same fashion as the past few days: at a minimum, patches of fog, potentially dense with visibility below ¼ of a mile at times, should develop overnight and should persist into mid-morning. As of this writing, a Dense Fog Advisory is in effect for Charleston County and Berkeley County around Cainhoy and Daniel Island through 10am. If fog does indeed persist and even expand, you’ll want to be sure to allow extra following distance and use low beams so that other drivers can more readily see you.
Once the fog mixes out, partly cloudy to mostly sunny skies will kick back in, and temperatures should respond by heading into the mid-70s by afternoon (sticking closer to the low-to-mid-60s near the coast, though, given much cooler shelf waters). Clouds should be on the increase in the evening as our next storm system approaches from the west.
Rest of the work week: Stormy Wednesday, then cooling back to January normals
We’ll see rain chances head up during the day Wednesday as a storm system and associated cold front approach the area. We’ll have one more day in the 70s as we get comfortably into the warm sector of the storm system. A line of showers and thunderstorms should be proceeding through the state during the afternoon, and enough instability and shear should overlap to perhaps bring a stronger storm or two with damaging wind gusts the main concern as of right now. We’ll want to watch forecast trends closely for Wednesday.
The line of storms should clear the area by midnight. From there, the front looks to lag a little bit, with the cooler air arriving during the day Thursday. Temperatures will top out in the upper 60s under a mix of sun and clouds. Cooler, drier air continues to work into the area for Friday, and we’ll be back into sweater weather mode with highs topping out in the upper 50s — much more in line with early January normals. Quiet weather continues into the weekend.
