Weekend forecast: Shower chances hang around, but no washout, either

/ at 7:43 PM

Surface low pressure will have pulled well away from the Lowcountry by Saturday morning, but we don’t get completely off the hook for rain chances this weekend with a lingering front and a warm airmass. Temperatures will run well above normal — we start the day in the upper 50s, warming to the low 70s in the afternoon. Cloud cover will feature prominently, and as mentioned, there is the risk for a few showers from time to time, but we should have a decent amount of rain-free time as well.

Sunday will be similar as the front continues to hang around. We’ll start the day in the mid-to-upper 50s once again, warming to the low 70s with sun peeking through cloud cover occasionally. The risk for showers remains, though it will be a little lower than we saw on Saturday. Shower chances will quiet down for Sunday evening, leading to a dry Monday before shower and thunderstorm chances return to the forecast for Tuesday through much of the upcoming week.

Friday & the weekend: Unsettled start to March

/ February 29, 2024 at 10:35 PM

We’ll get March — and climatological spring — off to a fairly wet start on Friday as moisture overruns the area throughout the day. We start the day within range of normal — generally the upper 40s — but only warm to the mid-60s in the afternoon as rain showers increase throughout the day. There could be some pockets of heavy rain at times, particularly depending on the positioning of a developing low pressure system, but right now the risk for the heaviest rain looks to stay offshore. Still, it’ll be a day for the rain gear as rain looks to continue well into Friday night.

Thursday turns much cooler ahead of an unsettled weekend

/ February 28, 2024 at 10:23 PM

We’ll wake up to much cooler air on Leap Day as a cold front will be long-gone by Thursday morning. Temperatures will start in the mid-40s, warming only to the low 60s at best as high pressure wedges into the area. We’ll get some peeks of sun at times, but the mid-and-high cloud deck will prove formidable. It’ll be a breezy day as well, especially in the early going. By evening, we will start to see more in the way of low-level moisture return to the area, which could bring a few showers late Thursday.
