We have a rainy day on tap for Saturday as a complex storm system sweeps across the eastern half of the country. We’ll start the day in the upper 30s to around 40°, but warm to around 60° in the afternoon as warm, humid air moves in ahead of the storm system’s cold front. We’ll stay in the rain for a fair bit of the day after daybreak, though there will be breaks at times as well.
Showers depart early in the day on Sunday, which will be the warmest day in the forecastable future as highs top out in the mid-60s ahead of the cold front. Said front should swing through by evening, and we’ll start to see a sharp change in the airmass after that as Arctic air spills into the region from the northwest. Lows on Martin Luther King, Jr. Day bottom out in the upper 20s, heading to only the low 40s despite plenty of sunshine.
After a day in which we received a trace of snow at the airport for the first time since the January 2018 winter storm, we will dry out on Saturday with low pressure moving away from the area. We start the day with showers tapering off in the early morning; these should be gone by mid-morning, though. Lows will bottom out in the 30s overnight but we’ll be warming up as the night goes on, and we should wake up to temperatures in the 40s Saturday morning. As low pressure departs, so does the cloud cover, and we should end up with a good bit of sunshine before it’s all said and done. Expect highs to reach around 50-51° or so — you’ll definitely still want the jackets.
Sunday starts out in frigid fashion once again with lows in the mid-20s expected. Highs will only reach about 50° despite plenty of sunshine as northerly winds continue to keep the airmass a little on the chilly side. The good news is that we should be largely dried out before Sunday morning’s freeze, so I’m currently not anticipating any traffic concerns. Stay warm and enjoy the weekend!
Expect largely quiet weather this weekend as high pressure generally maintains control over our weather. It’ll be chilly, though, even by January standards (especially Saturday). We start Saturday below freezing with lows around 30-31° in the metro, with wind chills dipping to the mid-20s around daybreak. As always this time of year, expect warmer low temperatures near the coast and even cooler temperatures in more rural, remote locations. High temperatures will only head to the low 50s in the afternoon despite plenty of sunshine. It’ll be pretty dry, too, with dewpoints mixing down to the upper teens in the height of the afternoon.
Sunday starts out on a similarly cold note, but we’ll start to see high pressure wane a little throughout the day ahead of the next storm system. Expect an uptick in cloud cover as Sunday goes on, but otherwise, winds turning a little more southerly will allow for temperatures to warm to the mid-to-upper 50s. Rain should hold off until after midnight, thankfully, so we’ll get the dry weekend intact.
The final weekend of 2024 will be unseasonably warm as we get into the warm sector of an approaching storm system that could bring some rough conditions on Sunday.
We’ve got a quiet weekend of weather ahead as high pressure remains generally in control. Notably, our starts will be a bit milder: expect Saturday to begin in the low to mid-40s, while Sunday starts in the mid-to-upper 40s as onshore winds help to take the edge off the chill a bit. Temperatures each afternoon head toward the mid-60s, and we can expect a mix of sun and clouds each day.
The only real issues with the weather this weekend come in the form of winds and tides. Saturday in particular will be a breezy day as high pressure butts up against a trough of low pressure that’ll be developing offshore. Winds stay elevated on Sunday, but won’t be quite as blustery.
The northeast winds along with the upcoming full moon will help drive water levels into flood stage in Charleston Harbor with the morning high tides. Saturday morning, we can expect a water level between 7.1-7.3′ mean lower low water with the 6:41am high tide, which is solidly within minor flood stage. We could approach moderate flooding with Sunday morning’s high tide, currently forecasted between 7.4-7.6′ MLLW around the 7:32am high tide. Moderate flooding begins at 7.5′, and this is the level when we start to see more widespread road closures downtown. If downtown’s in your plans early the next couple mornings, be ready to reroute around road closures. Otherwise, enjoy a nice weekend!
We are off to another frigid start on Saturday. Many spots in the metro will dip into the low 20s, with upper teens expected further inland. A Cold Weather Advisory is in effect for inland Berkeley and Dorchester counties, with the expected window of coldest air between 3-9am. Temperatures will moderate throughout the day, and we should get back above 50° once again, with highs topping out about in the low to mid-50s under sunny skies.
Temperatures will take another plunge toward freezing on Sunday morning, though we can expect lows to generally run some 10-12° above where they were on Saturday morning. This will mean that some spots inland will likely dip back into the low 30s once again, but much of the metro should stay just above freezing, especially the closer to the coast you are. We’ll see a few more clouds as high pressure starts to move offshore, and the resulting return flow will allow highs to peak in the mid-60s — much closer to normal for this point in December and some 20° warmer than we felt on Friday!
The warming trend continues for the first part of the week as the next storm system works into the area, with rain chances starting Tuesday and peaking Wednesday. The end of next week looks to close out below normal once more, though not to the advisory-level cold we’ve had recently.
We’ll add a little amplitude to the temperature rollercoaster as we get into the second half of the work week as one high pressure departs and another builds back in.
Bring in your pets and sensitive plants (or cover them if you can’t bring them in) as the first freeze of the season is expected tonight into Saturday morning to close out climatological fall and welcome in climatological winter on December 1. Temperatures will fall into the low 30s across much of the metro by morning, and a Freeze Warning is in effect for the entire Tri-County area as a result. Despite several days of cold air ahead, including even colder air next week, this will be the only Freeze Warning of the season as the growing season will come to an end on December 1, regardless of how far to the east freezing temperatures penetrate. Frost and freeze alerts resume on March 1, 2025.
After that very chilly start, we’re warming to only the mid-50s in the afternoon despite mostly sunny skies. Northerly winds 5-10 MPH will keep temperatures feeling like the mid-40s through early afternoon.
Winds go calm overnight Saturday into Sunday morning, and we’ll see another very chilly morning as a result, with the potential for widespread frost particularly inland. Lows should bottom out in the low 30s once more. (If it doesn’t freeze again, it’ll be close.) Highs will recover a bit to the upper 50s on Sunday afternoon, but that’s still well below normal for the first of December.
We have another shot of even colder air in store for early next week, with lows in the 20s across the metro possible Tuesday and Wednesday mornings. Tuesday may not even get out of the 40s! Colder-than-normal temperatures and rain-free conditions look to continue through next Friday.
Showers will move into the area overnight and persist into a good chunk of Wednesday as a cold front moves by. We start Wednesday in the mid-60s, warming to the mid-70s in the afternoon. Showers should scour out by early evening, and from there, cooler and drier air will begin to work into the area. The airmass change will be very noticeable this go-around; we’ll start Thursday in the mid-40s, warming to the low-to-mid-60s in the afternoon at best. Friday will be even cooler, with lows in the low 40s warming to just the upper 50s in the afternoon despite full sunshine, roughly 10° below the normal temperature for November 22 and more reminiscent of normal highs for early January!
Cool high pressure will be in control this weekend, and we will get a taste of more seasonable conditions for mid-November than we’ve had thus far this month.
First, though, there is the potential for major coastal flooding for the second time in three days with Saturday morning’s high tide, which is predicted around 7:46am. Water levels in Charleston Harbor are projected to peak between 8.1-8.3′ MLLW with this tide, and this will cause numerous road closures throughout downtown Charleston, as well as flooding issues on Isle of Palms, Mt. Pleasant, and perhaps even parts of James Island. Be vigilant and be ready to reroute in case you encounter a flooded road. A Coastal Flood Watch is in effect between 6-10am, and if trends continue, expect this to be upgraded to a Coastal Flood Warning. Also, if the predicted forecast height of 8.2′ comes to pass, it’d be a top-25 tide on record at Charleston Harbor.
Water levels should diminish by mid-morning, and from there, a fairly nice Saturday commences. Expect quite a bit of sunshine, with temperatures warming from the mid-40s in the morning to the upper 60s in the afternoon, just about right on target for normal for this point in the year. Sunday should turn a touch warmer, but a high of 70° is just a teeny bit warmer than normal, so that seasonable feel will continue. Unfortunately, another round of moderate to major coastal flooding is possible with Sunday morning’s high tide, though it should not be as severe as Saturday’s.
From there, a warming trend commences for the first half of the week before a mid-week front. The second half of next week looks much cooler than normal, with highs possibly not making it out of the 50s next Thursday! But let’s enjoy the weekend first.
