After a quick break from afternoon thunderstorms on Thursday, storms return to the forecast each afternoon through the weekend. Temperatures will remain on the hot side, too, with humidity joining mid-90s air temperatures to yield feels-like temperatures around 105°. Forecast post: chswx.com/blog/2023… Transcript

Our unsettled stretch of weather continues Thursday as more hot and humid weather starts the day followed by afternoon and evening thunderstorms along and ahead of the seabreeze. Watch for frequent lightning, heavy rain, and a possible wet microburst at times. We continue the risk for scattered to numerous afternoon thunderstorms into the weekend as well, with temperatures remaining in the 90s and...

Hot and humid days lead to unsettled afternoons and evenings each day for the rest of the week as we remain in an active pattern with the seabreeze instigating storms and disturbances riding atop the area giving them a little staying power. Forecast post: chswx.com/blog/2023… Transcript

Honestly a pretty standard summer day lies ahead for the Fourth of July here in the Lowcountry: expect highs to top out in the mid-90s with heat indices over 105° once again before thunderstorms fire in the afternoon. Forecast post: chswx.com/blog/2023… Transcript

Another hot day is ahead Monday with heat indices once again near 105° in the afternoon. Watch for a few seabreeze thunderstorms – a little more coverage than we’ve seen in the past couple days. We continue this trend into the Fourth of July before storm chances ramp up further from Wednesday on. Forecast post: chswx.com/blog/2023… Transcript

We continue to get progressively hotter for Sunday and beyond as heat indices head into the danger zone (110°+) by Monday. An isolated shower or thunderstorm is possible Sunday afternoon, but chances improve Monday and Tuesday with more moisture and a little more favorable upper-air configuration. Forecast post: chswx.com/blog/2023… Transcript

Heat and humidity will be increasing as the weekend goes on, peaking just in time for Independence Day on Tuesday. Watch for heat indices exceeding 100° on Saturday, then exceeding 105° each afternoon beginning Sunday. A few showers and thunderstorms are possible each afternoon, and we’re keeping an eye on the potential for a thunderstorm complex to bring some rain late Saturday into early S...

Progressively warmer and muggier conditions enter the forecast for Friday and beyond, with heat indices possibly approaching 110° by Sunday. Generally isolated to widely scattered storms are possible each afternoon, but we’ll watch upstream thunderstorm complexes just in case. Forecast post: chswx.com/blog/2023… Transcript

Thursday will feature one more day of relatively dry heat – highs in the mid-90s with heat indices maybe running a degree or two above the air temperature – before humidity builds back in starting Friday, leading to heat indices at or above 100° for the weekend and well into next week, including the July 4th holiday. Forecast post: chswx.com/blog/2023… Transcript

Plenty of sunshine will help drive highs on Wednesday back to the mid-90s. We’ll get progressively more humid heading into the weekend with air temperatures remaining in the low to mid-90s, and that could yield some Heat Advisory-level warmth at times. Forecast post: chswx.com/blog/2023… Transcript

We may see some showers and even a thunderstorm overnight Monday into early Tuesday morning, but that should clear the area by daybreak, yielding a mostly sunny and warm day with highs topping out in the low-to-mid-90s. Humidity won’t be horrible, though, which will keep those heat indices in check. We stick with this through the meat of the work week. Humidity starts to move back in Friday,...

Severe thunderstorms with damaging winds and large hail will be possible on Monday – but not necessarily a sure thing, either – ahead of a front that’ll get through Tuesday with a little reduction in dewpoints but continued highs in the low 90s. By the weekend, high heat indices exceeding 105° return to the forecast and may prompt Heat Advisories. Forecast post: chswx.com/blog/20...

Quiet weather continues Sunday as we top out in the low 90s in the afternoon under partly cloudy to mostly sunny skies. Attention then turns to the potential for strong to severe thunderstorms on Monday afternoon and evening ahead of a cold front. Forecast post: chswx.com/blog/2023… Transcript

The upper low that’s kept things unsettled this weekend has departed, yielding a quieter and warmer weekend of weather, with just a few storms possible Saturday afternoon. We could even get Sunday in rain-free. Tropical Storms Bret and Cindy continue to churn in the Atlantic, though they pose no further threat to land. Bret should dissipate this weekend, while Cindy suffers a similar fate by...

Expect one more unsettled day of weather on Friday as an upper low begins to lift out of the area. Thereafter, the weekend looks quieter with isolated to scattered afternoon storms possible Saturday followed by what should be a rain-free Sunday with highs topping out around 90°. In the tropics, Bret is affecting the Lesser Antilles as it encounters a more hostile environment, while newly-named Tro...

Off and on showers and thunderstorms will continue to be the order of the day on Thursday as the pesky upper low which has ruled our weather for the last few days continues to swirl nearby. Changes are coming, though, as the low finally moves away, yielding a quieter – and warmer – weekend. Forecast post: chswx.com/blog/2023… Transcript

A blocking pattern across the eastern US keeps us in quite a bit of unsettled weather for Wednesday through the rest of the work week. Expect highs in the mid-80s before thunderstorms fire; heavy rain and lightning are the main concerns. In the tropics, Bret continues to head toward the Lesser Antilles, but is forecast to shear apart by Saturday. 93L has yet to completely organize, but looks like...

We stay unsettled Tuesday – and, really, for the rest of the week – as a blocking pattern in the mid-levels keeps moisture and disturbances moving through the area. Also, Tropical Storm Bret was christened on Monday and is expected to become the first hurricane of the year as it approaches the Lesser Antilles later this week. Another disturbance behind Bret has a 60% chance of becoming...

We kick off an unsettled stretch of weather on Monday as a Rex block takes shape aloft, keeping the area under the influence of an upper level low through the end of the week. Expect numerous showers and thunderstorms each day. Highs Monday run in the upper 80s before dipping back to a rain-cooled mid-80s for much of the rest of the week. The tropics are also a little busy, with Invest 92L expecte...

Sunday will feature a little more humidity but overall still quiet weather aside from perhaps an afternoon storm or two along the inland-moving seabreeze. Expect temperatures in the upper 80s and feels-like temperatures around 90-91°. It might not be the worst day to get yard work in given what looks to be a soggy week ahead. Forecast post: chswx.com/blog/2023… Transcript

Saturday’s looking pretty good with highs around 90°, quite tolerable humidity for this point in the year, and only a tiny chance of an afternoon shower or storm. We keep this going – albeit with a little more humidity – into Sunday before unsettled weather returns for Juneteenth. Plus, a look at possible tropical formation in the east Atlantic by next week – a climatologic...

A few showers are possible Friday morning, but those yield to a mostly quiet weekend of weather with highs running around normal for mid-June with a little taste of standard Charleston humidity as well. Unsettled weather returns to the forecast for Juneteenth and beyond, with an unsettled next week ahead. Forecast post: chswx.com/blog/2023… Transcript

Thursday will feature highs in the mid-80s that’ll feel closer to the low 90s before another round of showers and thunderstorms ignites. The risk for severe weather is a little lower, but there could still be some strong winds and hail in a few storms. Forecast post: chswx.com/blog/2023… Transcript

Watch for some strong to possibly severe storms Wednesday afternoon and evening as another disturbance moves through the area. Temperatures will top out in the upper 80s before thunderstorms arrive. We warm to the low 90s by Friday as afternoon thunderstorm chances get a little lower thanks to diminishing upper-air support. Forecast post: chswx.com/blog/2023… Transcript

Another round of showers and thunderstorms, with a few of those possibly containing damaging wind gusts and large hail, will be possible Tuesday afternoon and evening across the metro area. We stay unsettled heading into the rest of the work week as well. Forecast post: chswx.com/blog/2023… Transcript
