Cloud cover moving over the area tonight will make for a much warmer start to Tuesday than we saw on Monday, with lows only dipping into the mid to upper 40s. Wakeups will trend even warmer as we get into the rest of the week, with lows in the 50s becoming commonplace through the weekend.

Keep an eye out for a few showers during the day on Tuesday as a coastal trough develops. Otherwise, expect temperatures to top out in the low 60s under mostly cloudy skies.

There will be a risk for a little salt water encroaching on roads around Gadsden Creek (Hagood/Fishburne/Lockwood) around the 6:10am high tide, but more significant flooding is not expected as water levels are expected to peak just shy of the 7′ coastal flooding threshold in Charleston Harbor.

We’ve got more clouds and chilly weather in store for Thursday after a rather chilly and somewhat dreary day across the Lowcountry. The high temperatures of 68° at the airport and 70° downtown on Wednesday were set right around midnight as cooler air filtered into the area throughout the day. We should see another near-normal morning Thursday (lows mid-40s) before temperatures once again struggle into the mid-50s in the afternoon, well below the usually nice normal November temperature around 69°. There’s a decent chance we should see a little sun before the day is out, but overall, expect more in the way of gray. Silver lining: No precipitation is expected.

Here comes the warmest day of this week! A coastal trough will move inland during the day Tuesday, which will allow some warmer air to infiltrate the area from the Atlantic. It remains to be seen just how far inland this warmer air can penetrate; we could see some spots near I-95 run much cooler, possibly not getting out of the 50s.

Expect a scattering of showers in association with the aforementioned trough, but it won’t rain all day at any one location. A couple of the models want to bring some instability inland, but the thinking is that any thunder stays over the water. Aside from slick roads from the rain, not expecting much in the way of any hazards from tomorrow’s weather.

Election Day will feature rain-free conditions, plenty of sunshine, and much cooler temperatures as high pressure to the north wedges into the area. This will definitely feel a lot different than the mugginess we’ve had for the past week-plus. You’ll want to keep a jacket around, too, as winds become gusty as the pressure gradient between the high building in from the north and Subtropical Storm Nicole to the south intensifies. Watch for gusts upwards of 25 MPH away from the coast, with gusts 30-35 MPH possible at the beaches.

The last total lunar eclipse of 2023 — and last one visible from the US until 2025 — will peak tomorrow morning just before 6am. The moon will be getting lower on the horizon in the western sky, but cloud cover should be sparse for eclipse viewing.

The full moon will also be a contributor to elevated water levels in Charleston Harbor with the 7:31 AM high tide, which is expected to peak around 7.6′, producing minor to moderate coastal flooding. This may have some impacts on the morning commute for folks traveling around downtown Charleston. Be ready to use alternate routes in case you encounter flooded or closed roads.

Mariners should take note that a Tropical Storm Warning has been hoisted for the coastal waters (not the harbor, yet) with very rough marine conditions expected to develop due to the aforementioned pressure gradient. There are no land-based tropical headlines as of this writing.

We’ve got another unseasonably warm day on tap for Sunday as an anomalously strong ridge of high pressure aloft continues to extend into the Carolinas. High clouds will favor prominently well ahead of a cold front to our west, but that won’t act as much of a governor on temperatures with low 80s still expected in the afternoon. Indeed, onshore flow is likely going to be the only thing keeping us from approaching the record high of 87° set in 2003.

The morning warmth is almost more remarkable: lows in the upper 60s are forecast, which is getting close to 20° above normal for this point in the year. We should fall shy of the record high minimum temperature of 71° set in 2003, but it does look like we’ll give the record a good run for the money.

A stray shower or two can’t be totally ruled out, but we’ll stay sandwiched between the front to the west and better instability and convergence over the waters and should stay dry as a result.

Finally, minor coastal flooding will be possible with the 6:05 AM high tide as we approach a full moon on Tuesday. Water levels approaching 7′ in the harbor could put some salt water on roads around Gadsden Creek once again — think Fishburne and Hagood — as well as spots along Lockwood (both Drive and Boulevard).

Weather’s looking good for Thursday as high pressure at the surface and aloft are in control. It will remain mild for November with temperatures running a few degrees above normal, especially in the morning. Expect plenty of sunshine with just a few passing clouds from time to time. If there’s one thing that might throw a fly in the ointment for an outdoors lunch, it’s that there will be a bit of a northeasterly breeze. Pin your napkins down appropriately and otherwise enjoy!

The only other weather concern will be the risk for some minor coastal flooding around the 5PM high tide. This could have commute impacts around Lockwood Dr. and the Citadel as salt water spills onto Fishburne and Hagood. If this is part of your evening commute, consider another route to avoid salt water splashing onto your car’s undercarriage.

A cold front will push offshore Tuesday allowing dry high pressure to build into the area from the west. Before the front gets offshore, though, patches of fog — perhaps dense fog — will be possible in the morning as lows only bottom out in the mid-60s, a rather warm start to the first day of November.

Slightly cooler and drier air will filter into the area once the cold front has passed, but ridging aloft will help temperatures head to about 80° once again in the afternoon with ample sunshine peeking through scattered clouds. Rain-free conditions are expected.

We keep a rain-free forecast heading into the rest of the week, with more onshore flow helping to curb temperatures closer to normal especially as we head into Thursday and Friday. 80s look to return for the weekend before our next rain chance next Monday.

A cold front is on its way through this evening, which will bring cooler temperatures for Thursday and beyond after highs peaked in the low 80s this afternoon away from the locally cooler coastline. Winds will go to the north and then the northeast overnight as high pressure builds in from the north and west. We’ll generally see scattered clouds throughout the day with those northeast winds keeping us about 5-7° cooler than we saw Wednesday. The aforementioned northeasterly winds and upcoming lunar perigee will contribute to another risk for minor to moderate coastal flooding around the 9:47am high tide, so be aware of the potential for closed roads once again tomorrow morning (though the peak of any tidal flooding should miss the bulk of any commute time at this point).

We’ll continue our warming trend on Tuesday ahead of a weak front that’ll come through later Wednesday. After starting around 50° thanks to clear skies and light winds, we’ll warm well into the upper 70s in the afternoon. We should see mostly sunny skies for a good bit of the day, with some higher clouds beginning to thicken later on. Rain-free conditions continue, and it should overall be another good day of weather across the area.

The only weather hazard of note will be the risk for some minor coastal flooding around the 8:20 AM high tide. Right now, water levels are forecast to peak around 7.1-7.3′ in the harbor, which will be enough to perhaps close a couple of the more vulnerable roads on the Charleston peninsula (such as around Hagood and Fishburne as well as near the City Market).

Some of us are going to get off to a frosty start on Thursday as temperatures fall into the mid-30s overnight, perhaps threatening the record low of 34° set in 1981. A Frost Advisory will be in effect from 4-9am for inland Berkeley and Dorchester counties as this is where temperatures are most likely going to be low enough to support frost formation. I don’t know that I could totally rule some patchy frost out a little further eastward as well in more sheltered spots. Bring in plants and pets tonight to be safe.

From there, full sunshine will begin to modify the chilly airmass that’s been in place over the past couple days. Highs Thursday afternoon will still run well below climatology for this point in October, but will be a few degrees warmer than we felt Wednesday, topping out in the mid-to-upper 60s.
