As low pressure moves eastward along the Gulf coast, we’ll keep the risk of showers and drizzle around through early Tuesday afternoon before high pressure begins to build in and cloud cover slowly breaks. Watch for areas of fog in the morning; be sure to use low beams and be prepared for visibility to drop quickly.

We should see a little sun before Tuesday’s gone, and there will be much more where that comes from as we get into the rest of the week. Temperatures could top out in the upper 50s, but this certainly will be dependent on how quickly the cloud deck can scour out.

The second half of 2019 will get off to a fairly hot start, with heat indices running in the low 100s each afternoon. Scattered thunderstorms will provide relief, particularly later in the week. (Must be July in Charleston.)
