Thursday's forecast: One more somewhat unsettled day, then the weather turns nice for the weekend
Hello everyone, Jared Smith here with your Charleston weather forecast for Thursday, September 14th, 2023, and taking a look at the weekend as well, and it looks like a pretty good one coming up.
A cold front will move through early Thursday morning, but the payoff will be a bit delayed as lingering moisture keeps shower and thunderstorm chances in the forecast in the afternoon and evening hours.
Expect highs to peak in the upper 80s, possibly for the last time for a while, as dewpoints in the 70s hang on for a few more hours.
The air mass change arrives in earnest overnight Thursday into Friday, and it will be very noticeable as dewpoints plummet into the 50s around daybreak.
Highs in the mid 80s will yield relative humidity values below 40%, quite comfortable indeed.
Clouds will be scouring out, and it should turn out to be a rather nice day.
You can have lunch outside, though, just mind a little bit of a northeasterly breeze around 10 miles an hour or so, and probably a little bit higher at the beaches.
Now Saturday is the pick day in my eyes.
We’ll start the day in the low 60s away from the coast, with highs topping out in the low to mid 80s in the afternoon, with dewpoints in the 50s again yielding relative humidity values well below 50%.
A cloud or two will be possible, but we should have otherwise unfettered sunshine.
Overall, Saturday looks like a great day to get out and about.
High pressure slips offshore late Saturday, and by Sunday, return flow starts to bring dewpoints back into the 60s, making it feel a little bit more humid, but still nothing heinous.
Highs top out in the mid 80s on Sunday, with clouds on the increase, and a stray shower or two can’t be ruled out late in the evening into the overnight either.
But we should still get much of the day in rain free.
Overall, the weekend’s looking pretty good, so I hope you get a chance to get outside and enjoy it.
And now a quick check of the tropics.
Swell from Hurricane Lee continues to bring some rough surf and a high risk of rip currents to the area.
It’ll pass north of our latitude by Friday, safely away from us to the east, as it heads towards Nova Scotia for the weekend.
The wind field is broadening as the storm gains latitude, and decent wind and water impacts are possible in the northeastern US.
Meanwhile, Margo will be generally meandering in the North Atlantic for a few days, as it spins down to a tropical storm from a Cat 1 hurricane thanks to cooler waters.
Margo remains no threat to land, and is only posing a hazard to maritime traffic.
Finally, our next depression should develop over the next couple days well out in the central Atlantic as it moves west-northwest.
Guidance generally brings this to hurricane strength, with another major hurricane not out of the question.
Early indications are leaning towards out to sea recurvature, but we’ll keep an eye on this one if anything changes.
And the good news is that it’s way out there, and there’s plenty of time to watch it.
If it does develop and reach tropical storm strength, as seems likely, it will get the name Nigel, unless something unforeseen gets to it first.
For now though, this wave poses no imminent threat to the Lowcountry, and there’s no other areas to worry about in the tropics right now.
And that was Charleston Weather Daily for September 14th, 2023.
