Thursday's forecast: Turning more unsettled as low pressure spins up offshore
Hello everyone, Jared Smith here with your Charleston weather forecast for Thursday, September 21st, 2023.
Our stretch of rain-free weather comes to an end on Thursday as low pressure spinning up offshore starts to send some showers our direction.
We’ll start the day on the mild side, generally in the upper 60s to around 70 degrees, and highs will top out in the low 80s between showers.
There is the risk for some heavy rain, particularly in the morning and early afternoon, and we may hear a rumble of thunder as well.
The northeasterly breeze will turn up, with some gusty winds expected, particularly at the coast.
There’s a chance some minor coastal flooding could develop around the 1241pm high tide as well, something to watch, but right now it doesn’t look horribly disruptive.
Low pressure will continue to affect the area on Friday, with a continued risk for showers coming ashore as well as some gusty winds that could cause some coastal flooding with the early afternoon high tide.
Winds will gradually go more northerly as the day goes on, and that will help keep high temperatures capped to around 80 degrees.
A more northwesterly trajectory begins to take hold on Saturday, and that will keep highs in the upper 70s with one more day of isolated showers possible.
The low departs to the north by Sunday, and that will bring some more pleasant weather to the area with highs rebounding into the mid 80s.
There is still the risk for the aforementioned low to develop some tropical characteristics as it moves northward.
The National Hurricane Center is giving this area a medium chance, or about 40%, to develop over the next few days.
So as things look right now, if the storm does take on a subtropical or tropical structure, the worst of the weather would remain offshore.
A wobble to the west, of course, could make things a little windier and a little rainier in our neck of the woods, but overall, this remains nothing to take a cow down over, and so I wouldn’t get too caught up in the tropical aspect.
Unless, of course, you have maritime considerations, and then I would be paying a little closer attention.
Elsewhere in the tropics, Hurricane Nigel continues to churn in the central Atlantic as it heads towards extratropical transition by the weekend.
Meanwhile, a wave coming off of Africa today has a 70% chance to develop into a tropical cyclone over the next few days as it moves across the eastern Atlantic.
It’s way out there, though, and currently poses no threat to us here in the Lowcountry, but of course, we’ll keep an eye on it.
And that was Charleston Weather Daily for September 21st, 2023.
