Hello everyone, Jarrett Smith here with your Charleston weather forecast for Wednesday, September 20th, 2023, as well as the rest of the work week.

We’ve got one more generally rain-free day of weather before things begin to turn a little more unsettled heading into the weekend.

We start Wednesday in the mid-60s away from the coast, where it’ll run closer to 70, and we’ll warm into the mid-80s in the afternoon under partly cloudy skies.

Overall, nothing too shabby.

Shabbiness slowly increases though, heading into Thursday and Friday.

We’ll start to see low pressure develop somewhere off the southeast coast, and a trough will sharpen near the coast, perhaps providing a focal point for a few isolated showers and thunderstorms in the afternoon.

Northeasterly winds will also be turning a little more breezy, especially at the coast.

Expect highs on Thursday to top out once again in the mid-80s.

Onshore flow will continue to strengthen Friday, and this, combined with more in the way of showers and storms, will hold highs into the mid to upper 70s on Friday afternoon.

Unsettled and breezy conditions should continue into Saturday before gradually improving Sunday, but this is all dependent on the timing, location, and forward speed of the low pressure system.

There will be more adjustments to this forecast, so stay tuned for updates.

The aforementioned low pressure area could still take on some tropical characteristics, especially if it sniffs out the Gulf Stream a little bit more.

It is unlikely to turn into anything terribly strong or disruptive if this happens, though.

The National Hurricane Center holds this area at a 30% chance to become at least subtropical through the weekend.

Regardless of how the storm is structured, it certainly seems our impacts locally would be pretty close to the same, so I really wouldn’t get too worked up about it.

Elsewhere in the tropics, Nigel continues to churn as a hurricane as it begins to accelerate north and northeastward into Friday, losing its tropical characteristics as it goes.

Meanwhile, a wave moving off Africa sometime on Wednesday will have a chance to develop into a tropical cyclone as it moves across the eastern Atlantic heading into next week.

It’s way out there, though, and doesn’t currently pose any imminent threat to our area.

We’ll keep an eye on it, of course, in case that ends up changing.

And that was Charleston Weather Daily for September 20th, 2023.
