A relatively quiet Saturday will give way to a somewhat turbulent Sunday as a potent winter storm brings heavy rain to the Lowcountry. Temperatures on Saturday will generally run in the upper 50s as cloud cover increases as the storm approaches from the west. We should get much of Saturday in rain-free, with the better rain chances arriving at and after midnight.

Let’s start with the good news: Friday looks pretty good, with highs around 60° in the afternoon under mostly sunny skies. Much of Saturday looks to be okay as well, with showers not expected to start until later in the afternoon/early evening. And then there’s Sunday.

Thursday will run several degrees warmer than what we saw today, bringing a brief return to the 60s as winds turn a little more out of the west. A weak trough looks to stir up some cloud cover particularly later in the day. While a shower can’t totally be ruled out, it is highly unlikely that we’ll see any rain.

We continue to watch trends for a Carolina winter storm this weekend. So far, confidence continues to increase in precipitation remaining all liquid across the Charleston metro area, and that is the going NWS forecast as a result. There are still many details to be worked out over the next few days as we start to get into range of the higher-resolution mesoscale models, so stay tuned for updates as the weekend draws near.

After one more freezing cold morning across the Tri-County — perhaps the coldest since late November with lows in the 20s spreading well into the metro area — a warming trend will commence to get us over the hump and into the end of the work week. Wednesday afternoon will feature temperatures running about 5-7° above where we topped out on Tuesday, with upper 50s expected under mostly sunny skies. Cloud cover will tick up overnight Wednesday into Thursday as a weak front approaches, possibly even generating a shower or two. We’ll see more sun on Friday with temperatures remaining within spitting distance of normal for mid-January here in Charleston.

We’ve got another chilly Tuesday in store as lows drop below freezing away from the coast tonight. Expect temperatures around 30-31° to begin the day in the Charleston metro area, with upper 20s further inland. Winds will make it feel like the mid-20s, though, so be dressed with layers accordingly.

Despite full sunshine, high temperatures will only top out around 50° in the afternoon. This runs about 10° below normal for this point in January.

Otherwise, no other major weather hazards are expected. Enjoy your Tuesday.

We’ll see some showers and thunderstorms overnight as a cold front approaches the area. No severe weather is expected, but some gusty winds and brief heavy downpours are possible as the line gets through. Rain should clear the area before daybreak.

Once the front is through, temperatures will plummet and clouds will scour out. Expect high temperatures to only top out around the mid-50s with some afternoon sunshine. Then, we’ll have a pretty cold night overnight Monday into Tuesday morning, with lows getting into the upper 20s in the metro area away from the coast. Highs on Tuesday will only top out in the upper 40s despite full sunshine.

After another somewhat hard freeze Wednesday morning, temperatures will begin to moderate some as an upper disturbance approaches from the west and high pressure slips offshore. We might see a few showers Thursday morning as the disturbance swings through, but will close the work week with mostly sunny skies. Showers re-enter the realm of possibilities for the weekend as another front approaches the area. Temperatures will remain generally around if not a click or two below normal.

After a couple slightly warmer days, a reinforcing shot of cooler air arrives for Friday into Saturday. Highs will once again top out in the mid-50s both days despite plenty of sunshine. A freeze is even likely for most of us away from the coast on Saturday morning, too. By Sunday, though, high pressure quickly slips offshore and the southerly return flow turns the heat pump back on, sending us into the low 70s in the afternoon ahead of an advancing cold front. There could be some shower chances late Sunday, but the best risk of rain right now appears to be overnight Sunday into Monday morning as the front swings through. All in all, not a bad-looking weekend with a little something for both cool-weather and warm-weather fans.

Additionally, tomorrow should be only the second time this year that we will not have any coastal flooding concerns in Charleston Harbor. Water levels once again peaked just over 7′ this morning, making it 5 of 6 days so far in 2022 with some tidal flooding to contend with. (The one day there was no flooding? Monday, when the windstorm blew the tide out well below predicted levels.)

After a couple chilly days post-storm, temperatures will trend back up in a big way for Wednesday as high pressure slips southward, sending winds in a more westerly direction. After just topping out at 54° today, look for highs in the mid-60s on Wednesday with a mix of clouds and sun as a coastal trough lingers nearby. The mid-60s continue into Thursday ahead of a cold front which could bring us a few showers late in the day. By Friday, the front will have cleared and temperatures will once again run in the mid-50s as cooler high pressure builds in from the west.

Expect these cool temperatures to persist into Saturday before warming up big-time on Sunday ahead of a more potent front, which by Monday evening into Tuesday could bring us an even cooler airmass linked to strong high pressure building out of the Plains.

Coastal flooding will once again be an issue with Wednesday morning’s high tide, predicted to peak around 7.5′ around the 10am hour. This will once again cause minor to moderate coastal flooding in parts of downtown Charleston and could close a few roads. Be ready to use alternate routes in case you encounter a flooded road.

Tuesday’s weather, in a word: Quieter. It will also be much less windy than today was, though that’s not a hard bar to reach either. We’ll start the day around freezing in the metro area, with upper 20s further inland, while places near the coast will stay above freezing. Mostly sunny skies will be the rule, with cloud cover increasing a bit as the day goes on.

The main weather hazard for Tuesday will be the potential for moderate coastal flooding with the morning high tide. The forecast is for water levels to reach 7.8′ around 9am. This will certainly be high enough to close several roads in downtown Charleston, including the Highway 61 off-ramp from the Ashley River southbound bridge as well as parts of Lockwood Drive. Be ready to use alternate routes if downtown is in your commuting plans.

Tonight’s forecast is rather tricky. We’ve had a good bit of rain across much of the Tri-County today that has helped to knock temperatures back into the 60s in most spots, but it is still conceivable that a few severe thunderstorms may develop overnight.
