Our run of warm temperatures, which peaked Friday with a record-tying high of 82° at the airport, will be coming to an end this weekend as a storm system affects the area.

While Valentine’s Day looks lovely, Sunday will decidedly not live up to its name as a storm system affects the area. From there, quite a warming trend develops, especially for the second half of next week.

A chilly — but, thankfully, mostly sunny — weekend lies ahead as a reinforcing shot of cool air works its way in on Saturday. We’ll start Saturday in the mid-30s, but somewhat brisk northwesterly winds will drive the wind chill into the upper 20s to low 30s. Another push of cooler and drier air moves in during the day, and highs will only peak around 50° as a result with brisk winds continuing. Gusts to 25 MPH will be possible during the day, so keep that in mind for any outdoor activity you’ve got planned.

Well, it certainly appears as if the third time will be the charm for snow-lovers in the Lowcountry as a long-anticipated winter storm system impacts the area this weekend. A Winter Storm Warning goes into effect Saturday at 7AM and will run until Sunday at 1PM. Meanwhile, an Extreme Cold Warning will also go into effect Saturday at 7PM until noon Sunday for air temperatures in the mid-to-upper teens and wind chills dropping perhaps as low as 3° above zero in the morning — extraordinarily rare cold air for this part of the world.

While it won’t be quite as chilly as Tuesday was, the rest of the week will continue to feature below-normal temperatures as Arctic air continues its residence across the area. Wednesday starts in the upper 20s, warming to the low 50s in the afternoon under a mix of sun and clouds. A dry front will sag south across the area Thursday, which will cool things off and cloud up the skies a little bit. Temperatures Thursday once again start in the upper 20s, warming to the upper 40s to about 50° in the afternoon. The cloud cover insulates us a bit overnight Thursday into Friday, with lows only dropping to the low 30s (and staying above freezing toward the coast). Highs Friday warm to the mid-50s as more onshore flow takes over.

A reasonably busy weekend of weather awaits in the Lowcountry as we deal with the south side of a massive and likely potent winter storm, the effects of which are starting to develop across Texas into the Midwest before spreading eastward during the day tomorrow into the Mid-South and eventually to the Eastern Seaboard.

For our part, a Winter Weather Advisory has been hoisted for inland Berkeley and Dorchester counties, with some freezing rain expected between Saturday night and Sunday morning. Elsewhere in the Charleston Tri-County area, we’ll deal with periods of cold rain as well as some windy conditions. Comparatively, though, this will be this storm on easy mode for a lot of us — some really treacherous conditions are likely to develop across the northern half of the state into NC. Read on to learn what’s most likely to happen in your neck of the woods.

Topsy-turvy temperatures will feature prominently this weekend as a decently strong cold front comes through on Sunday. Ahead of that front, Saturday temperatures will warm from the mid-30s in the morning to the mid-60s in the afternoon as warmer air pumps in from the south and southwest. We’ll see clouds on the increase as the day goes on with the approaching front and a strong trough of low pressure that’ll help drive that front through and bring some much-needed rain for Sunday.

A lot has been made of the risk for winter weather on Sunday, but the ultimate outcome looks to be mostly rain for the Charleston metro area, with some flakes likely mixing in the further west toward I-95 you go. The front itself gets through early in the day, with the precipitation developing behind it as the trough of low pressure swings through. While it will stay mostly rain near the coast, a few flakes could mix in along and west of 17-A. However, accumulating snow, if snow falls at all, is not expected given surface temperatures in the upper 30s to mid-40s. Travel issues beyond the elevated risk of distracted driving at the sight of novelty snowflakes are not expected.

After a record high on Friday, we’ve got one more warm day ahead before a cold front begins to make things feel a little more like January for Sunday and especially the start of the new work week.

The first rain chance of the new year arrives on Saturday as low pressure along a cold front develops and approaches the area. We’ll clear out in time for a pleasant and seasonable Sunday, though.

Quiet weather continues this weekend, though the temperature rollercoaster will continue to roll on as record highs Saturday yield to cooler (but still warmer-than-normal) temperatures on Sunday.
