Some of us are going to get off to a frosty start on Thursday as temperatures fall into the mid-30s overnight, perhaps threatening the record low of 34° set in 1981. A Frost Advisory will be in effect from 4-9am for inland Berkeley and Dorchester counties as this is where temperatures are most likely going to be low enough to support frost formation. I don’t know that I could totally rule some patchy frost out a little further eastward as well in more sheltered spots. Bring in plants and pets tonight to be safe.

From there, full sunshine will begin to modify the chilly airmass that’s been in place over the past couple days. Highs Thursday afternoon will still run well below climatology for this point in October, but will be a few degrees warmer than we felt Wednesday, topping out in the mid-to-upper 60s.
