Weekend forecast: Heat and humidity build with a slight chance of afternoon thunderstorms
Hello everyone, Jared Smith here with your Charleston weather forecast for Saturday, July 1st, 2023.
Taking a look ahead at the Independence Day holiday as well.
Heat and humidity will continue to build this weekend as strong high pressure takes hold across the area.
We start Saturday in the low to mid 70s and top out in the mid 90s in the afternoon, with maybe even some warmer readings even further inland.
Dew points will only mix out to around 70 degrees or so, and this should yield heat in the seas generally around 100-101 during peak heating.
A shower thunderstorm along the sea breeze can’t be ruled out, but I suspect much of us get Saturday in rain free.
Now one possible fly in the ointment as we get later into Saturday and early Sunday is the potential for a thunderstorm complex to head into the area from the north.
Guidance does show it weakening as it gets closer, but it is very possible we may see some rain late Saturday into early Sunday morning, particularly the further north you are.
These are tough things to pin down even a day out, so stay tuned to forecast updates just in case.
The thunderstorm complex, if it comes by, should be out of our way by daybreak Sunday.
Temperatures should respond appropriately by heading back into the mid 90s in the afternoon after once again starting in the 70s.
Dew points approaching the mid 70s should yield heat in the seas over 105 degrees, which is the point where heat stroke becomes a real concern.
Be sure you are getting plenty of water and taking breaks in the shade if you are outside Sunday afternoon.
There remains the potential for an isolated storm or two on the sea breeze in the afternoon and evening as well, but don’t count on any relief from thunderstorms.
We continue to warm as we get into Monday and Tuesday, with highs getting well into the mid 90s both days.
Dew points in the mid 70s will continue to yield heat in the seas in the 105-110 degree range, and that is hot.
Ridging begins to weaken as we get into Tuesday, and that will mean a slightly higher chance for an afternoon or evening thunderstorm for the 4th of July, so keep an eye on that if you have outdoor activities, but don’t cancel anything either.
And finally, we’ll be keeping an eye on evening high tides beginning Saturday for the potential for some minor flooding.
High tide on Saturday evening is around 7-10pm, and should peak right at 7 feet.
On Sunday, it’ll peak around 8-03pm at around 7.1 feet or so.
While this won’t cause widespread problems downtown, there will still be some spots taking on saltwater, particularly the vulnerable locations near Haygood and Fishburn as well as along Lockwood.
Be ready to route around flooded roads as well as moving a little further up the beaches when high tide comes in.
And that was Charleston Weather Daily for July 1st, 2023.
