Hello everyone, Jared Smith here with your Charleston weather forecast for Monday, September 18th, 2023, and a look at the week ahead.

After a very soggy day across the Charleston metro on Sunday, featuring weather stations recording 3-5 inches of rain in many spots, as well as another round of downtown flooding, we get at least a couple days to dry out to start the work week.

Monday actually looks pleasant, weather-wise anyway, as we start the day in the upper 60s with some fog in the area.

Temperatures head to the mid-80s in the afternoon under mostly sunny skies, and dewpoints drop into the low 60s, making for a fairly comfortable day to have an emotional support lunch outdoors as we go back to work.

We’ll keep this going into Tuesday as well, with an even cooler start in the low 60s away from the locally warmer coastline, and maybe a couple more clouds in the afternoon.

Winds go a little more northeasterly on Wednesday, and a shower or two could get caught up in the mix in the afternoon and evening hours, but much of us get that day in rain-free as well as we once again top out in the mid-80s.

From there, things get a little more unsettled.

I think I called it weird on the blog, and yeah, it is kind of weird too.

Low pressure should spin up somewhere near or just off the coast starting Thursday, and it’ll move northward towards the area for Friday and into at least the first half of the weekend.

What kind of form it takes is somewhat up in the air.

It’ll look a lot like a nor’easter, but given the time of year and warm waters nearby, we do need to watch it for possible subtropical formation, especially if it stays out a little more over the water.

The National Hurricane Center gives this area a 20% chance to take on some tropical characteristics later this week as it moves northward.

Regardless of whether the storm is a cold-core low, a warm-core tropical cyclone, or a hybrid, it looks like the impacts are going to largely be the same.

Periods of rain, with gusty winds, especially at the coast.

Beyond that, it’s just tough to know.

The bottom line, though, is that right now this doesn’t look like something to take a cow down over just yet.

But if that changes, I’ll let you know.

Otherwise, the tropics continue to percolate.

The National Hurricane Center has written the final advisories for Margot and Lee as those storms have completed extra-tropicals transition, and Tropical Storm Nigel should become a major hurricane by Tuesday, though it will be staying out to sea, only posing a risk for maritime traffic.

Finally, the Hurricane Center gives the wave forecast to emerge off Africa earlier this week a 50% chance to develop into a tropical cyclone over the next several days.

It’s way out there, and nothing we really need to be concerned about at this point.

It’d be a solid week and a half or so before we even needed to really start to pay attention to the storm if in fact it looked like it was going to be a problem.

Which, given the pattern out there, chances are good it probably won’t be.

But that’s why we watch them.

And that was Charleston Weather Daily for September 18th, 2023.
