Unsettled weather is expected on Wednesday as a potent storm system brings us a good bit of much-needed rain, particularly in the afternoon into the evening. Lows start in the mid-40s, warming just to the mid-50s in the afternoon owing to the rain-cooled state of play. If you have travels taking you northward into the Midlands and beyond, there’s a risk for some winter weather as well, especially getting into NC and VA where ice and snow will be the rule. There will be too much warm air in our neck of the woods for any winter weather, and I suspect that is probably okay with many of you!

The week ahead will be notable for the return of cooler-than-normal temperatures to the forecast, especially after a mid-week storm system moves by which will send morning lows below freezing for the first time since the mid-January snowstorm.

Sunday will be a very breezy day as a highly dynamic storm system moves across the eastern half of the continental United States. Showers and a few thunderstorms should set up in a line ahead of a cold front which will come through generally between 11am and 1pm, according to NWS. The line of showers and storms could produce damaging wind gusts to 60 MPH, which could prompt some Severe Thunderstorm Warnings for tree damage and possible power outages. Even outside of storms, gusts 40+ MPH will be possible, especially on bridges and overpasses. A Wind Advisory goes into effect overnight through about 5PM.

Rain will be offshore by evening, and winds will die down as the front clears the area. This will set up a much cooler week ahead, with a mid-week secondary front likely to send us back below freezing for the first time since the January snow later in the week.

A cold front that brought showers and a few thunderstorms to the Lowcountry — including a tornado warning for Hilton Head Island — is through the area, and we’ll start Friday on a much cooler note as a result. Expect lows in the low 40s Friday morning, warming only to the upper 50s in the afternoon despite much more sunshine.

A warm front will lift north of the area overnight, scouring out some dense fog and sending much warmer and more humid air into the area ahead of an approaching cold front. Within the warm sector, we’ll start in the mid-50s, warming to the mid-70s early on before a line of showers and maybe a few thunderstorms approaches the area, generally affecting the metro between 10am-4pm. Severe weather is unlikely this far north where instability is a bit more meager, but a rumble of thunder or two with a strong wind gust is still not totally out of the question. You won’t need the rain gear all day, though, as storms should be offshore by evening with the front following thereafter.

The temperature rollercoaster takes another upswing Wednesday and Thursday before dipping again Friday as a series of fronts affect the area.

Astute @chswx readers will note that Wednesday’s forecast high is about 10° cooler than the 74° that was advertised yesterday. High-resolution model guidance is strongly suggestive that the wedge front will take longer to move northward across the area as a warm front than previously thought. In fact, there’s some indications that it may stall out right across the Tri-County for a time, which certainly makes for a tricky temperature forecast. Right now, the going forecast is the mid-60s with mostly cloudy skies expected.

A wedge of cool high pressure hangs tough on Tuesday, bringing another gray and cool day to the area. Temperatures start in the mid-40s, warming to the low 60s in the afternoon — right around normal for this point in February. There’s going to be a risk for some showers from time to time, but an all-day rain isn’t expected.

After a record-breaking stretch of warmth over the past few days, we turn much cooler and cloudier for Monday as a backdoor front slides south and cooler high pressure wedges into the area in its wake. We could see some showers in the morning, but otherwise expect a mostly overcast day as lows in the mid-50s only warm a few degrees, perhaps not even cracking 60° in the afternoon. This stands in stark contrast to the record high of 84° set on Sunday, smashing the previous record for the date of 80° set in 1949. And while it’s been easy to forget with such warm weather, it is still February, and these things happen.

It was an incredibly warm February day in the Lowcountry, skipping ahead from a spring preview to an early summer preview as the high topped out around 84° at the airport. This high temperature obliterated the old daily record of 80° set in 2019, and was 22° above normal for February 7.

Record warmth will remain possible this weekend, especially on Sunday, before temperatures moderate (but remain above normal) as the pattern turns a little more unsettled for next week.

Abnormally warm weather continues for Friday and the weekend as warm high pressure continues to rule the roost for a few more days. We will have a front stall out nearby on Friday; while we’ll be on the warm side of the frontal zone, there’s still a risk for some isolated to scattered showers at time especially getting into the afternoon. A rumble of thunder isn’t totally out of the question, either. Despite the slight risk of showers, temperatures should still head into the upper 70s, threatening February 7’s daily record high of 80° set in 2019.
