Tuesday’s forecast: Showers return

/ at 8:19 PM

Tuesday’s forecast will be unsettled at times with periods of showers ahead of a cold front that’ll advance through the area on Wednesday. It’s going to be a warm and humid day, with lows around 60-61° warming to the mid-70s in the afternoon. Shower chances will increase as we get into Tuesday night and early Wednesday, and some rumbles of thunder may be possible as well. We need the rain and it looks like we could get a fair bit of it in spots. A half-inch of rain seems to be a decent bet in many locations, with locally heavier amounts possible as well.

Weekend forecast: Lots of sun, warm Saturday, cooler Sunday

/ November 17, 2023 at 5:29 PM

Showers will depart overnight Friday, and we look to have a rather nice and warm Saturday ahead. We’ll start the day in the upper 50s and warm to the upper 70s in the afternoon with plenty of sunshine to be had. A cold front will then pass through Saturday evening with nary a whimper, just a gradual drop in dewpoints with temperatures to follow. We start Sunday in the low 50s — a few degrees warmer than recent forecasts — and warm to about 70° in the afternoon. Sunshine will once again be in abundance, and it’ll be another gorgeous (and more seasonally-appropriate) weather day.

Looking ahead: Showers will return to the forecast for the first half of Thanksgiving week with temperatures generally around or above mid-late November norms. From there, a strong cold front looks to sweep through, knocking temperatures down well below normal — thinks highs in the upper 50s to around 60° — just in time to make Thanksgiving Day feel like, well, Thanksgiving Day.

Friday & the weekend: One more day of tapering showers, then turning nice

/ November 16, 2023 at 10:41 PM

Showers will gradually depart as Friday wears on thanks to low pressure moving away from the area. It’ll be an unseasonably warm day, with lows starting near 60° before temperatures top out in the low to mid-70s in the afternoon. We’ll see some breaks in the clouds between showers, so once again, we’re not expecting a totally gray, washed out day. The only other issue will be the potential for some minor salt water flooding around the 10:25am high tide; expect water levels to peak around 7′ or so, putting some salt water once again on Hagood at Fishburne and perhaps on Lockwood. Widespread flooding issues are not expected.

The weather improves just in time for the weekend. Clouds will be decreasing Saturday as deeper moisture departs. We start the day in the mid-50s before warming into the low 70s in the early afternoon. From there, a cold front will get through later in the day; expect a dry passage thanks to much drier air in place. Sunday will be noticeably cooler — expect lows in the mid-40s, some 10° cooler than Saturday morning — before warming to around 70° in the afternoon.
