A chilly start to meteorological winter

/ December 1, 2019 at 11:12 PM

Meteorological winter began today, and it will definitely feel a little chilly as we start the work week off with highs topping out in the mid-50s. Temperatures will moderate a bit to the low 60s heading into Wednesday and Thursday. We’ll remain dry for much of the work week. Our next rain chance could come as early as Friday afternoon and may persist into the weekend; there’s a lot of model disagreement around specifics here, so stay tuned for forecast fine-tuning.

Cool start to the weekend; next rain chance Sunday

/ November 28, 2019 at 8:46 PM

A dry cold front will swing through tonight, knocking high temperatures down to around 60° for Black Friday despite plentiful sunshine. Bundle up if you’re headed out to shop early in the day, as wind chills will be in the mid-30s.

We stay fairly cool on Saturday as clouds increase ahead of our next front, with highs topping out in the mid-60s. Rain looks likely Sunday, particularly in the afternoon. Be ready to enact Plan B for outdoor activities. Temperatures will rise into the low 70s ahead of the front, before heading below normal for the first full week of December.

Pleasant end to the work week

/ November 19, 2019 at 10:46 PM

We’ve got a nice stretch of weather coming up over the next few days as high pressure passes through the area, suppressing rainfall and bringing along plenty of sunshine. Temperatures will be rising over the next few days, perhaps reaching 70° by Friday — right near normal for mid-November.

Our next front (and rain chance) swings through roughly Saturday afternoon into the evening. Timing is still tough to pin down. Don’t cancel outdoor plans just yet, but have a secondary plan ready to go.

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!

Warmer for much of the week, but more cool weather to come

/ 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.
