It’s a low bar to clear, but Tuesday will be much quieter than Monday was weather-wise as drier air noses in from the northeast. This should be enough to keep storms, much less significant cloud cover, at bay for a day. We start the day in the upper 60s to around 70°, warming to about 90° in the afternoon under mostly sunny skies. Unfortunately, we’ll need the good weather for some cleanup after severe storms brought large hail and damaging winds to the Summerville area on Monday evening.

After highs topped out in the mid-90s on Sunday, we’ll see temperatures back down a little bit toward normal heading into the upcoming work week as a front crosses through and stalls out nearby, potentially bringing a somewhat unsettled Monday. Showers and thunderstorms could be in the area during the morning hours, but the better chance for rain arrives in the afternoon and evening as more forcing arrives. Temperatures start in the mid-70s, heading to around 90° under a mix of sun and clouds.

We’ve got quite a warm weekend ahead with plenty of sunshine. Thankfully, humidity will not play a major role as dewpoints mix out to the 50s on Saturday and the low 60s on Sunday. In fact, Saturday could be one of those days where the heat index is actually lower than the air temperature at times as relative humidity values will head down to around 35% during the height of the afternoon.

Sunday may end up as the hottest day thus far in 2024. The forecast high of 98°, if it verifies, would be the warmest day since August 14, 2023, when it was also 98°. Thankfully, we’ll keep dewpoints in the low 60s, which will keep heat indices below 100°. Still, 98° is plenty, plenty hot — if you’ll be outside, make sure you’re taking breaks and staying hydrated. Don’t forget the sunscreen, too, especially if you’re headed to the beach — it’s prime UV season, after all.

Despite the heat, thunderstorm chances will be nil — just too much dry, sinking air for afternoon thunderstorms (much less a robust cumulus field!) to develop. The next rain chances arrive Monday, and we could stay somewhat unsettled heading into next week as a front stalls out nearby.

Mother Nature will come out throwing heat this weekend — thankfully coming along with lower dewpoints than we typically see in summertime. A “cold” front swings through during the day Friday, and while the airmass will trend drier, it’ll still be quite warm — highs in the mid-90s are expected. Thankfully, the drier air keeps heat indices within a degree or two of the air temperature. Sunshine will be in abundance, with the dry, sinking air keeping cloud cover at a minimum.

We’ll keep this going into the weekend. Saturday will be the “cooler” of the two days, but still plenty warm with highs reaching the low to mid-90s under mostly sunny skies. Sunday turns a little warmer and a touch more humid, with highs solidly in the mid-90s under mostly sunny skies once again. The next shower or thunderstorm chance arrives Monday afternoon as dewpoints continue to climb heading into next week.

Scattered thunderstorms return to the forecast on Wednesday afternoon, once again focusing inland along and ahead of the seabreeze. It’ll be another mild start around 70°, warming to near 90° in the afternoon. Dewpoints around 70° will help drive heat indices to around the low to mid-90s.

Thunderstorm chances peak Thursday ahead of a cold front. Expect scattered to numerous storms to develop ahead of the seabreeze first as temperatures head to the mid-90s with dewpoints in the low 70s. Heat indices should crack 100° in the afternoon, so if you have outdoor plans, be ready to move those indoors. Thunderstorm chances will approach the coast later Thursday evening into the overnight as the front draws closer, and a stronger storm or two can’t be totally discounted. Be alert to quickly changing conditions if your Thursday night includes some out and about time.

The front clears the area Friday. It won’t get cooler, but the dewpoints will be dropping throughout the day, so while highs top out in the mid-90s once again, we shouldn’t see the heat indices we saw on Thursday. A stray storm might be possible in the afternoon, but all in all we should see plenty of sunshine and a rain-free day for many.

Warm and muggy conditions can be expected for the rest of the work week, with some periods of thunderstorms possible especially Wednesday and Thursday.

Tuesday starts around 70° and warms to near 90° in the afternoon. A few thunderstorms will be possible, particularly further inland near the I-95 corridor. Not everyone will see storms, and the Charleston metro area in particular should be clear of any unsettled weather by evening in the wake of the seabreeze.

Disturbances aloft working with ample instability will maximize shower and thunderstorm chances Wednesday and Thursday. The best risk for storms will be during the afternoon and evening hours. Severe weather isn’t expected, though storms could pack some gusty winds where outflow boundaries collide. Temperatures Wednesday top out once again near 90°, while we turn even warmer on Thursday with highs in the low to mid-90s. Given dewpoints in the low 70s, we could get close to heat indices around 100°.

A front approaches the area on Friday, but drier air will be working its way in, so while temperatures will be similar to Thursday (low to mid-90s), dewpoints will be trending lower. This should also keep the thunderstorm risk a little more at bay, leading into a generally quiet weekend.

Humidity continues its slow climb on Sunday as onshore flow from the Atlantic gradually sends dewpoints higher. Most of us should stay rain-free, though some guidance does show the potential for a few showers to brush coastal areas in the morning. There’s also the risk for a few popup storms generally near I-95 in the afternoon, but the vast majority of the Charleston metro stays rain-free.

Temperatures head to the mid-80s after a mid-60s start. As alluded to earlier, dewpoints will continue to creep upward, generally remaining in the low 60s. This’ll yield relative humidity values generally in the 45-50% range — still far from horrendous, but you might notice a little more sweat.

Welcome to the 2024 hurricane season, everybody. From now through November 30, we’ll keep one eye out on the Atlantic basin for whatever spinny mischief may try to get going. The outlook for this year is for an incredibly busy season thanks to flat-out hot water well into the Atlantic and the expectation that we’ll be in La Niña, which tends to relax shear over the Atlantic and turbocharges the environment for tropical cyclone formation as a result. Of course, the outlook only shows how many storms will probably form; it’s not an indicator of how many of those will make landfall, much less where they may do so. It only takes one storm to make a season memorable for all the wrong reasons, too.

The good news to start the season is that tropical cyclone development isn’t expected for the next seven days. We didn’t even have any preseason activity this year for the first time since 2022. However, as we all know, tropical cyclones can spin up on a dime, so it’s important for us all to be prepared. To paraphrase John Philpot Curran, Thomas Jefferson, and others: the price of living in Charleston is six months of tropical vigilance.

We’ve got no major weather concerns for the start of June and climatological summer. Saturday starts on a cooler-than-normal note once again, with lows bottoming out around 60° away from the beaches. Highs climb to the mid-80s with tolerable humidity, though dewpoints shouldn’t dry out as much as they ended up doing on Friday. We’ll see a little bit more in the way of cloud cover, but there’s going to be plenty of sunshine, too.

High pressure shifts offshore Sunday, kicking off a warming trend that’ll have us back in the 90s by early next week. Dewpoints will continue their gradual climb to more traditional early-June levels, though humidity still should remain generally tolerable. We start Sunday in the low 60s one more time, warming to the mid-to-upper 80s in the afternoon. A stray thunderstorm or two will be possible well inland in the afternoon, generally closer to the I-95 corridor, but the vast majority of us stay rain-free.

Enjoy the weekend!

We’ll close out May with plenty of sun, temperatures generally near if not slightly below normal (especially in the mornings), and reasonably low humidity. Friday looks to run a little warmer than Thursday did, but the northerly breeze will keep the air on the dry side as dewpoints fall into the low 50s during the height of the afternoon. Expect mostly sunny skies, with just a few passing clouds as moisture remains a little tough to come by.

Saturday will be one more really nice day before a warming trend kicks in beginning Sunday. Temperatures on Saturday will once again bottom out in the low 60s, with highs in the mid-80s in the afternoon. Dewpoints will creep up a couple degrees, but it should still feel plenty comfortable outside as relative humidity values drop below 35% in the afternoon. Dewpoints begin to rebound to more June-like levels on Sunday as high pressure starts to slip offshore. Expect a milder start to Sunday with lows bottoming out in the mid-60s, warming to the mid-80s in the afternoon with a little bit more mugginess in the air as dewpoints return to the 60s. This warming trend continues into next week, with highs returning to the 90s and slight afternoon shower and thunderstorm chances coming along for the ride as well. But first, we have a beautiful weekend to enjoy — so enjoy it!
