Hello everyone, Jared Smith here with your Charleston weather forecast for Monday, September 25th, 2023, and the week ahead.

Well, even though the autumnal equinox passed on Saturday, Monday clearly did not get the memo that it’s officially fall.

We should see temperatures head up to around 90 degrees in the afternoon under mostly sunny skies.

Fortunately, dew points will be well in check, so there are no major concerns around heat index, but still, it’s a little warmer than we want to be at this point in the year.

This begins to change Tuesday, though, as high pressure starts to wedge into the area from the northeast.

Highs on Tuesday top out in the mid 80s with a few showers possible, and from there, highs look capped around the upper 70s to around 80 degrees each day into the weekend.

Showers will be possible each afternoon, particularly Wednesday and Thursday, as the coastal trough tries to sharpen.

Meanwhile, strengthening northeast early winds will help drive tidal departures into flood stage at times of high tide, possibly starting as early as Tuesday evening, but more likely starting Wednesday into Thursday.

We could see moderate flooding with the evening high tides beginning Wednesday, and guidance, though often somewhat overblown, suggests that major coastal flooding might not be out of the question later this week.

Stay tuned to coastal flood advisories from the National Weather Service, as they will likely be required later this week.

Meanwhile, the tropics generally continue a decent level of activity as we close out September.

Tropical Storm Philippe is moving west-northwest through the central Atlantic, likely to remain a tropical storm over the next few days as it contends with wind shear.

Philippe currently represents no threat to land, much less our neck of the woods.

The National Hurricane Center is watching two other areas for possible development.

The first, a wave south of the Cabo Verde Islands, tagged 91L, is likely to develop into a depression at some point this week.

It’s a long way out there, and right now looks like it’s going to follow Philippe, track-wise anyway, for the next few days.

It doesn’t appear to be a threat to us.

If that changes, I’ll let you know.

The second area is a disorganized cluster of storms in the southern gulf that has a slight chance to organize a bit more into something tropical before shear increases later this week.

It looks to move westward across the gulf and doesn’t look to be a concern for our weather here.

And that was Charleston Weather Daily for September 25th, 2023.
