Frosty start to Thursday gives way to a comfortable afternoon

/ November 18, 2020 at 10:15 PM

Clear skies and light winds will allow temperatures to drop into the upper 30s overnight, likely causing some frost to develop away from the coast. The National Weather Service has issued a Frost Advisory that includes Berkeley and Dorchester counties for early Thursday. Make sure you cover up your plants and have your pets in a warm place tonight.

Once we get clear of the frost, we’ve got a pretty solid November day ahead with highs topping out in the low 60s under mostly sunny skies and a bit of a northerly to northeasterly breeze.

Reinforcing shot of cold air to bring sweater weather on Wednesday

/ November 17, 2020 at 5:59 PM

Get your sweaters ready — Wednesday is going to be a chilly one. A dry cold front featuring a reinforcing shot of cold air will swing through the area tonight. By tomorrow morning, winds will be back out of the north and a little breezy — lows in the low 40s may feel closer to the mid-30s when factoring the wind in. Despite full sunshine, temperatures will only rise into the mid-50s given continued cold advection into the area.

As high pressure slips overhead Wednesday night, winds will calm and skies will remain clear, allowing for excellent radiational cooling conditions. We may be contending with some frost as we get into overnight Wednesday/early Thursday morning, especially in the inland tier of counties. Keep an ear out for a possible Frost Advisory from the National Weather Service, and be ready to ensure plants, pets, and people are protected. (Pipes will be okay — not expecting a freeze just yet.)

Picture-perfect Tuesday ahead

/ November 16, 2020 at 9:09 PM

High pressure will remain solidly in control of our weather Tuesday with another beautiful mid-November day ahead. Highs will top out in the upper 60s after starting out in the low 40s (and maybe the upper 30s inland) with nary a cloud in sight. This will put temperatures right around, if not a little bit below, normal for mid-November.

A few more showers for Tuesday; latest on Eta

/ November 9, 2020 at 9:21 PM

Expect a bit more in the way of cloud cover and showers for Tuesday as a moisture plume courtesy of Tropical Storm Eta begins to spread northward. Temperatures will remain rather warm for this time of year. We’ll start the day in the upper 60s to low 70s (especially near the coast). Temperatures will top out in the low 80s, with periods of cooling where showers develop. Shower chances will continue to ramp up with time on Tuesday, with thunderstorms becoming likely as we head into Wednesday.

The week ahead: Above-normal temperatures, coastal flooding continues

/ October 18, 2020 at 10:21 PM

Temperatures will head back above normal this week with shower chances coming back into the picture starting Tuesday. Showers will be isolated to scattered at best for most of the week as a coastal trough persists. Onshore flow will keep dewpoints up, making for a warm and humid mid-to-late October week. Expect highs in the 80s just about every day with lows in the mid-60s. (Closer to the coast, take a couple degrees off the high and add it to the low.)

Coastal flooding — perhaps major — possible at times of high tide this weekend

/ October 16, 2020 at 9:39 PM

Astronomical influences and onshore winds will send water levels in Charleston Harbor well into flood stage at times of high tide this weekend. Moderate to major coastal flooding (8.0′ MLLW) will be possible with each morning high tide through at least Monday, while minor flooding is expected with each evening high tide. Road closures will be possible at times of high tide, with some routes becoming temporarily cut off due to salt water inundation.

Fall arrives, but brings exceptionally high tides with it

/ September 19, 2020 at 9:47 AM
Radar and temperatures as of 8:30am Saturday, September 19.

If you step outside this morning, you’ll notice a welcome lack of humidity as high pressure wedges in from the north, drying out the air at the surface (though cloud cover will remain in place today thanks to some moisture trapped between 4-6,000 feet as well as some upper-level energy that will stir up high cloud cover later today). Dewpoints this morning were running well into the low 60s, with even a reading of 59° at Charleston International Airport at 8am.

Unfortunately, this surge of Fall weather will also come with several rounds of major coastal flooding this weekend into early next week.

The week ahead: Off and on rain continues, but temperatures finally abate

/ September 13, 2020 at 10:27 PM

So the first thing you will undoubtedly notice in the seven-day is that it is largely bereft of 90s (save for Monday). You may also notice a high of 79° for Sunday. Yes, that’s out there a ways and could still be tweaked upward, but it is just refreshing to see 70s for highs somewhere in the forecast. We’ll need to deal with some rain and coastal flooding to get here, though.

Warmer and unsettled this week, with a side of tidal flooding

/ April 5, 2020 at 11:38 PM

After a rather pleasant weekend, temperatures will begin to trend back above normal this week with chances of showers and perhaps a few thunderstorms each afternoon. Highs will be getting into the mid-80s by midweek, marking a return to that summer preview we were feeling toward the end of March. A cold front will move through the area sometime later this week, bringing a reduction in temperatures, but showers may yet stick around. It’s a fairly low confidence forecast looking toward next weekend with a fair bit of divergence in the models, so stay tuned for updates as things will undoubtedly need to be ironed out.

[UPDATE 3] Significant coastal storm may disrupt holiday travel Monday

/ December 21, 2019 at 11:09 PM

Holiday travel will become increasingly difficult as a low pressure system develops in the Gulf of Mexico and heads our way Sunday into Monday, bringing heavy rainfall, gusty winds, and the threat for coastal flooding to the area.

8:30 PM: This post has been updated with the latest forecast information.
