Hello everyone, Jared Smith here with your Charleston weather forecast for Wednesday, September 27th, 2023, as well as a look at the rest of the work week.

High pressure will wedge into the area starting on Wednesday, and this will keep us on the cool side of normal for the next few days.

Moisture moving across the wedge will keep cloud cover in the area, though there will be some breaks at times as well.

We’ll see some showers too, though rainfall amounts should stay generally on the light side.

Highs on Wednesday will top out in the upper 70s.

We’ll keep this going into Thursday as well, with a shower or storm still not out of the question, and by Friday we should start to see some drier air begin to work back into the area, and that should help to scour out some of the cloud cover.

That in turn will allow highs to creep up a couple more degrees, breaking 80 degrees once again.

But not getting too high there, 80-81 probably Friday afternoon.

Coastal flooding will be the main weather concern for the rest of the work week though.

Expect water levels to approach major flood stage Wednesday evening with a 7-11pm high tide.

This should have impacts on the evening commute, though probably closer to the tail end this go around.

Be ready to reroute around flooded roads if you’re out and about Wednesday evening as road closures should be numerous, and remember this is salt water.

No good for your vehicle’s undercarriage, don’t drive through it if you can help it.

Expect the morning commute to be impacted by moderate coastal flooding on Thursday, and even greater impacts are possible a Friday morning’s commute, as moderate to major flooding will be possible with high tide peaking just before 8.30am.

Stay tuned for updates on this, and keep an ear out for coastal flood watches, warnings and advisories from the National Weather Service.

Out in the tropics, Philippe is really struggling with wind shear, and doesn’t appear to be terribly long for this world as a tropical cyclone.

It will continue to move west and northwest, and is forecast to degenerate into a post-tropical cyclone by the weekend.

Philippe is no concern for us here at home.

I know the maps look a little bit scary with it continuing to trend west, but it’s probably going to fall apart.

The other area of concern in the Atlantic is Invest 91L, which is way out there in the central Atlantic.

It should develop into the Atlantic Basin’s next depression in the next day or so, and it may in fact have already developed by the time you hear this.

It’s got a lot of room to maneuver out there, and we have plenty of time to watch it.

The indications from guidance are somewhat split on where it’ll go, with a fair bit of members turning it northward, but some take a weaker storm further west.

We’ll keep an eye on it of course, but right now there’s no concern from 91L here in the Low Country.

And that was Charleston Weather Daily for September 27th, 2023.

I’m Jared Smith.
