Hello everyone! Jared Smith here with the Charleston weather forecast for Monday, October 30th and the week ahead.

Well, we tied a record high on Sunday.

The high temperature at North Charleston reached 85 degrees, tying the record first set on this day in 1946.

And we’ll challenge another record on Monday, as highs should once again head to the mid-80s, approaching the record high of 85 set in 1949.

But boy oh boy do things begin to change starting on Halloween.

A front will get through at some point on Tuesday, leading to an increase in cloud cover and maybe a shower or two in the afternoon, but don’t count on it.

The main thing we’re watching with this front is the shot of the coldest air so far this season.

Right now it looks like there will be a little delay in the cooler and drier air moving into the area behind the front, but that could all depend on exact timing of the front, so stay tuned.

Right now the forecast high for Tuesday is about 77 degrees, dipping to the upper 60s or so by trick-or-treat time, but I wouldn’t be surprised if temperatures rain cooler than this though, again depending on whether the front can get through sooner.

Regardless, cold air will be strongly advecting into the area by overnight Tuesday, and we start Wednesday much cooler with lows in the mid-40s.

Persistent cold advection thanks to breezy northerly winds will cap high temperatures in the upper 50s on Wednesday afternoon.

We haven’t done that since April 8th.

Thursday should start in the upper 30s away from the coast, with highs only reaching the low 60s in the afternoon despite nearly unfettered sunshine.

Yes, folks, sweater weather is indeed making its first appearance this season.

I hope you’re prepared.

The air mass will modify though, and the much cooler weather will not last terribly long.

We’ll start Friday in the low 40s before warming to the upper 60s to around 70 in the afternoon, and by the weekend we’re back to highs in the low to mid 70s once again.

And so it goes during transitional seasons here in the Lowcountry.

Coastal flooding will remain a concern for at least the next few morning high tides as well.

Monday morning’s high tide peaks around 940 AM, and should head to about 7.4 feet or so on the cusp of moderate flooding.

Expect some road closures at times, especially in the most vulnerable areas downtown.

We’ll likely repeat this Tuesday and Wednesday as well, though commute impacts will decrease as the tide peaks more in the mid-morning hours.

Stay tuned for coastal flood advisories from the National Weather Service.

Finally, there are a couple areas in the tropics to watch, but nothing for us to worry about.

One of them is northeast of the Bahamas, but it has a very limited time to get going at this point as shear increases atop the storm, and its chances to develop are decreasing with each outlook.

The second area, a broad swath outlined in the Southern Caribbean, is where low pressure may develop this week, and whatever gets going has a 30% chance to become tropical right now.

We’ll keep an eye on it, but again, it’s nothing to get overly concerned about at this point, if ever.

And that was Charleston Weather Daily for October 30th, 2023.
