Coastal storm to bring rain for Saturday, chilly temps throughout the weekend

/ November 15, 2019 at 11:21 PM

This weekend will remain chilly and breezy as a coastal storm takes shape. Rain will continue to be a factor Saturday as the low develops and gradually moves offshore. Wet weather will taper off as Saturday night progresses, leaving us with a mix of sun and clouds for Sunday. Temperatures will remain well below normal, with highs around 50° for Saturday and in the mid-50s for Sunday. Breezy NNE winds will contribute to the risk for coastal flooding around times of high tide Saturday (10:01 AM, 10:27 PM), with moderate flooding possible in the morning. If heavier rain develops around times of high tide, flooding could be worsened. Keep the winter rain gear close — you’ll be happy you have it Saturday!

Freeze expected overnight, coastal flooding with morning high tide

Wednesday will be the coldest day in the Charleston metro area since early March as an Arctic airmass, rushing in tonight, makes a brief visit to the Lowcountry through Thursday morning. Many locations will experience a freeze, and wind chills will be heinous (think low 20s). Time to dust off the jackets!

/ November 3, 2019 at 10:22 PM

After a very refreshing weekend of below-normal temperatures, we will be headed back into the 70s for a few days starting Monday. (For what it’s worth, highs in the 70s are normal for early November.) However, another round of unseasonably cool weather is on tap for the weekend.

Fall goes on hold for Halloween

/ October 27, 2019 at 5:03 PM

While much of the nation will close October out with fairly cold temperatures, a sliver of warmth will hug the East Coast, keeping temperatures closer to late September/early October normals for the work week. Upper-level disturbances will keep the weather rather unsettled as well, with rain chances Tuesday-Friday before a cold front ushers fall back into the picture for the weekend.

A strong storm or two is possible Tuesday

/ October 21, 2019 at 11:08 PM

Another cold front will be moving through the area on Tuesday, bringing along some more fall-like weather for Wednesday and beyond. Before it passes, though, we’ll see temperatures spike into the mid-80s with scattered thunderstorms in the area. A few thunderstorms could produce strong, gusty winds in the late afternoon/early evening hours. Be alert to possible warnings.

The front is expected to clear the area around sunset or a little later. Temperatures will cool down nicely behind said front, bottoming out in the low 50s for Wednesday morning.

It’s hard to believe that after the coolest morning since April 27, we are talking about the potential for a little tropical mischief in the Gulf. But, it’s still hurricane season, and this one has a shot at bringing us some much-needed rain over the weekend.

After the wettest day since Dorian, a ridge of high pressure will usher in fall weather for a few days, with the potential for the first 40° readings of the season Thursday and Friday mornings. Then, a slug of tropical moisture will bring in another solid rain chance late this weekend into next week.

A nice weekend concludes; much-needed rain coming next week

/ October 13, 2019 at 7:57 AM

Sunday will finish with a little more warmth than we’ve had the last couple days as high pressure slips offshore and a front stalls out nearby. Clouds will be on the increase throughout the day, but rainfall is expected to hold off until overnight. Highs will top out in the mid-80s; with dewpoints in the 60s, this will feel a little warmer and more humid than we felt on Saturday.
