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.

We’ve got a few more warm and muggy days ahead to start 2023 before a front gets through mid-week, bringing temperatures closer to early January normals.

2022 will come to an unsettled end across the Lowcountry as showers and perhaps a few thunderstorms develop and move through ahead of a cold front. A stronger storm or two will be possible near I-95, but otherwise expect generally off and on showers. The best risk for showers will occur in the afternoon through the early evening hours; yes, it is conceivable we may have the precipitation out of here as the clock strikes midnight. It will certainly be mild, with highs in the low 70s. Temperatures will run in the upper 50s as 2023 begins, so it should be fairly comfy with a light jacket.

The atmosphere will be drying out during the day Sunday, with cloud cover decreasing and some drier air moving in. It’ll still be warm, though, thanks to high pressure ridging aloft: once again, expect highs in the low to mid-70s. Overall, not a bad start to 2023!
