Unfortunately, as expected, widespread flooding is ongoing in downtown Charleston this morning as heavy rain combined with high tide to close numerous roads. Heavy rain will continue throughout the day, with another 4-6″+ expected across much of the Tri-County area through tonight.

Holiday travel will become increasingly difficult as a low pressure system develops in the Gulf of Mexico and heads our way Sunday into Monday, bringing heavy rainfall, gusty winds, and the threat for coastal flooding to the area.

The week ahead: Warm start, chilly finish as we barrel toward Christmas

/ December 15, 2019 at 10:15 PM

The last work week before Christmas will start out feeling a little more spring-like, with highs topping out in the low 70s Monday and Tuesday before a cold front swings through and sends temperatures a little below normal for Wednesday and Thursday. We’ll see a little warmup as we head into the weekend.

The best chance of rain so far this week will come on Tuesday, primarily from noon into the overnight, as showers and perhaps a few thunderstorms ahead of the aforementioned cold front come through. We’ll then want to watch the weekend for the potential for another coastal storm to get started. There’s a fair bit of uncertainty there still, so don’t change any plans just yet, but keep an eye on the forecast as rain chances become more clear.

Unsettled week ahead

/ December 9, 2019 at 6:35 AM

It’ll be a bit of a topsy-turvy weather week this week. A warm front will lift north of the area this morning, bringing some rather mild weather to the area for today and Tuesday with highs getting into the mid-to-upper 70s despite mostly cloudy skies.

A cold front will swing into the area on Wednesday, bringing with it a chance of showers. In the wake of said front, high pressure will build in from the northeast in a “wedge” pattern, which will keep low clouds and a low-end chance of showers in the forecast for Thursday. By Friday, we’ll be watching the progress of a low pressure system coming out of the Gulf for the potential of periodic downpours as we head into the first part of the weekend. Much refinement will be needed as timing becomes clearer as the week goes on, so be sure to watch forecast updates!

A chilly start to meteorological winter

/ December 1, 2019 at 11:12 PM

Meteorological winter began today, and it will definitely feel a little chilly as we start the work week off with highs topping out in the mid-50s. Temperatures will moderate a bit to the low 60s heading into Wednesday and Thursday. We’ll remain dry for much of the work week. Our next rain chance could come as early as Friday afternoon and may persist into the weekend; there’s a lot of model disagreement around specifics here, so stay tuned for forecast fine-tuning.

Cool start to the weekend; next rain chance Sunday

/ November 28, 2019 at 8:46 PM

A dry cold front will swing through tonight, knocking high temperatures down to around 60° for Black Friday despite plentiful sunshine. Bundle up if you’re headed out to shop early in the day, as wind chills will be in the mid-30s.

We stay fairly cool on Saturday as clouds increase ahead of our next front, with highs topping out in the mid-60s. Rain looks likely Sunday, particularly in the afternoon. Be ready to enact Plan B for outdoor activities. Temperatures will rise into the low 70s ahead of the front, before heading below normal for the first full week of December.

A pleasant Thanksgiving approaches

Pleasant end to the work week

/ November 19, 2019 at 10:46 PM

We’ve got a nice stretch of weather coming up over the next few days as high pressure passes through the area, suppressing rainfall and bringing along plenty of sunshine. Temperatures will be rising over the next few days, perhaps reaching 70° by Friday — right near normal for mid-November.

Our next front (and rain chance) swings through roughly Saturday afternoon into the evening. Timing is still tough to pin down. Don’t cancel outdoor plans just yet, but have a secondary plan ready to go.

Coastal storm to bring rain for Saturday, chilly temps throughout the weekend

/ November 15, 2019 at 11:21 PM

This weekend will remain chilly and breezy as a coastal storm takes shape. Rain will continue to be a factor Saturday as the low develops and gradually moves offshore. Wet weather will taper off as Saturday night progresses, leaving us with a mix of sun and clouds for Sunday. Temperatures will remain well below normal, with highs around 50° for Saturday and in the mid-50s for Sunday. Breezy NNE winds will contribute to the risk for coastal flooding around times of high tide Saturday (10:01 AM, 10:27 PM), with moderate flooding possible in the morning. If heavier rain develops around times of high tide, flooding could be worsened. Keep the winter rain gear close — you’ll be happy you have it Saturday!
