Sunday: Showers and maybe a thunderstorm or two possible, especially later in the day

/ February 14, 2026 at 10:07 PM

A storm system will affect the area on Sunday, bringing us some showers at times and maybe even a few thunderstorms as we get into the afternoon and evening hours. We need the rain as moderate drought continues to envelop the area, and a half-inch to even an inch of rain will be possible. While that won’t put an end to the drought by any stretch, it will certainly help.

Friday & the weekend: Warming up, but turning unsettled on Sunday

/ February 12, 2026 at 7:45 PM

Another quiet and generally seasonably pleasant day is head on Friday. We get off to a bit of a chilly start as lows fall to the mid-to-upper 30s in the morning. A northeasterly breeze will make it feel closer to freezing to start the day, but temperatures will warm to around 60° in the afternoon under predominantly sunny skies. This is a few degrees below mid-February norms, but nothing too outrageous.

After a front gets through overnight, we’ll turn cooler for Thursday as temperatures head ever-so-slightly below normal. We’ll start Thursday in the upper 30s to around 40°, warming to the low 60s in the afternoon under predominantly sunny skies. While not quite the 70s, it’ll still be a solid mid-February day in the Lowcountry.

Rest of the work week: Showery Wednesday before turning cooler

/ February 10, 2026 at 6:39 PM

We had quite the temperature swing on Tuesday, with a low of 33° giving way to a high of 76° in the afternoon. A warm front that swung through around daybreak helped temperatures jump from 37° a little after 6am to 46° about 20 minutes later, according to the National Weather Service. From there, plenty of sunshine propelled us to the warmest day since January 10.

I hope you got to enjoy the brief spring preview, because the weather will turn more unsettled on Wednesday as a cold front approaches from the northwest. Temperatures will still run well above normal, with lows in the low 50s yielding to highs once again approaching 70° in the afternoon. Showers will begin to move into the area as early as daybreak, with off and on showers possible through the evening hours.
