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.

Weather winning streak continues into the weekend

/ April 3, 2020 at 10:14 PM

Did you like today? Excellent — there’s more on the way for Saturday as temperatures top out in the mid-70s once again under mostly sunny skies. High pressure will then slip into the Atlantic turning winds more onshore for Sunday, boosting humidity a little and providing for more partly cloudy skies, but comfortable temperatures in the mid-70s continue.

Only things to watch out for this weekend (besides coronavirus!):

Otherwise, this weekend’s weather will be enjoyable even if the circumstances aren’t so hot. Try to get outside — it will be good for your soul.

Excellent weather day ahead for Friday

/ at 7:35 AM

We have a beautiful Friday coming up for outdoor social distancing activities: mid-70s with low humidity in the afternoon under sunny skies as high pressure has full control of the weather situation. It’s a great day to work from home in the backyard or perhaps have some outdoor home school lessons. (I promised The Dog that I’d throw him the ball this evening, so that’s how I’m going to take advantage.) Remember, beating COVID-19 isn’t just about six feet of personal space or avoiding crowds — it’s also about taking time to do things for your mental health as well. This weather should hopefully help in that regard.

Beautiful day ahead

/ April 2, 2020 at 7:47 AM

The stratocumulus clouds are gone, and after the chilliest start since early March (mid-40s!), we look to have a really gorgeous day ahead with highs around 70° under sunny skies thanks to a broad area of high pressure across much of the eastern half of the continental United States. Just because we’re all in on social distancing doesn’t mean you can’t go outside. It’s good for the soul. Enjoy!

No fooling: Quite a bit cooler as we start April

/ April 1, 2020 at 7:42 AM

I knew it was coming, but the chill in the air was somewhat shocking as I went to read the rain gauge this morning! In the wake of yesterday’s storm system which, thankfully, had more bark than bite for our neck of the woods, April will start out significantly cooler with clouds gradually decreasing as the day goes on. You’ll want a light jacket as temperatures will only rise into the mid-60s this afternoon. Enjoy the brief return to #hoodieweather before above-normal temperatures re-establish themselves getting into next week.

Tornado watch cancelled

/ March 31, 2020 at 2:36 PM

UPDATE 6:18 PM: The tornado watch has been canceled.


The Storm Prediction Center has issued a tornado watch for the Lowcountry, including the entire Charleston Tri-County area, until 9PM. We in #chswx continue to watch an area of low pressure strengthen as it heads eastward. While instability is lacking, wind shear is plentiful, and the approaching low pressure will only assist in ramping this up. Thus, the watch.

Strong storms possible Tuesday evening

/ March 30, 2020 at 6:26 PM
Tuesday's forecast: Evening thunderstorms. A few could be strong to severe. Low 60, high 74.

March would end on a stormy note, wouldn’t it?

Much of Tuesday looks to remain dry, but we will be watching low pressure coming out of AL and GA throughout the day as it could bring a few strong storms to the area depending on how far north it gets. Overcast will help keep temperatures in the mid-70s throughout the day, but any breaks in the clouds could add some fuel for storms. Right now, the best risk for severe weather looks to be in southern Georgia, but we are right within the margin of error. If storms do turn strong to severe, damaging wind gusts would be the primary concern. Stay alert for forecast tweaks and changes tomorrow.

This storm system will usher in quite the airmass change as we get into Wednesday and beyond. Wave goodbye to the 80s for a little bit as temperatures plunge below normal Wednesday and Thursday before recovering back to normal (mid-70s) for the weekend.

Stormy Tuesday, then a more seasonable week ahead

/ March 29, 2020 at 5:15 PM

After a downright summer-like weekend, more seasonable conditions (with even some below-normal temperatures) will assert themselves as we kick off April. First, though, we’ll get a few showers and storms through the area on Tuesday.

Record heat possible this weekend

/ March 26, 2020 at 6:01 PM

Weather will turn sharply warmer on Friday as Mother Nature boots up the heat pump, with record highs in the forecast Friday through Sunday. Records at the airport are likely to fall all three days as a rather strong subtropical ridge builds in from the south and surface winds swing around to the south and southwest. The ridge will help keep any sort of thunderstorm activity at bay, too, with just fair weather cumulus mixing in for some brief relief from sunshine from time to time. Dewpoints will stay relatively sane in the mid-60s, so while it’ll be hot, it won’t be quite as humid as we might find in the summertime. Temperatures moderate some as you get closer to the coast, with mid-80s expected in downtown Charleston, and mid-to-upper 70s at the beaches thanks to water temperatures around 65°. Suffice to say, this is a terrible weekend for beaches to be closed. Please continue to stay close to home and do your part to ensure we can stop the spread of COVID-19!

Tuesday turns warmer with scattered showers, maybe a storm

/ March 23, 2020 at 7:02 PM

After a stubborn high pressure wedge held firm across SC for a good bit of the day, we will warm significantly on Tuesday as low pressure moves across a pesky frontal boundary which is expected to lift north across SC as the day goes on. Highs should top out in the upper 70s in most spots; wouldn’t be surprised to see an 80° reading peek through depending on how much sun can break through cloud cover. Said low pressure will help spur on some scattered showers and thunderstorms. It won’t rain all day, and rain amounts should generally be light, though a few downpours cannot be ruled out.

Most of us should not be headed out and about unless it is for essential trips for provisions or prescriptions. To the grocery workers, pharmacists, medical professionals, and first responders still heading into the community despite the threat from coronavirus, we salute you all.
