Friday & the weekend: Below-normal temperatures with unsettled periods continue

/ August 7, 2025 at 11:04 PM
Weather forecast for Charleston from August 8 to 10. On Friday, expect scattered thunderstorms in the evening with a high of 85°F and a low of 72°F. Saturday will have PM storms expected, with temperatures reaching 85°F during the day and dropping to 72°F at night. Sunday will also see PM storms, with a high of 84°F and a low of 73°F. The graphic was created on August 25 at 6:17 PM, with data sourced from the National Weather Service.

After an unusually cool and cloudy early-August day across the Lowcountry, in which highs largely did not breach 80° (good for a new record cool high temperature at North Charleston, breaking the record of 80° set just last year), we should see a bit more warmer air tomorrow as the high pressure wedge which reasserted itself today weakens a bit toward the coast. This will allow the seabreeze to get going a bit more, setting us up for an afternoon of scattered storms, with the best risk of precipitation generally east of 17-A. Lows in the low 70s will warm to the mid-80s in the afternoon — still several degrees below normal for this point in August — but it’ll still be somewhat muggy.

Friday & the weekend: One more hot day, then turning cooler — and stormier

/ July 31, 2025 at 8:23 PM

The end to the heat wave is in sight, but we have one more day to go before a front moves in from the north, replacing the oppressive heat with numerous showers and thunderstorms for the weekend. (Sorry.)

[Updated] Thursday: Another Extreme Heat Warning day for some with afternoon storms

/ July 30, 2025 at 9:57 PM

The heat wave rolls on into Thursday as we continue to sit between low pressure to the west and high pressure over the Atlantic, funneling warm and humid air into the area. We once again look to get off to a very warm and humid start with lows topping out in the upper 70s inland to low 80s near the coast. Temperatures will then warm to the low-to-mid-90s in the afternoon before showers and thunderstorms kick off, cooling some spots down. Daytime heating combined with mid-to-upper-70s dewpoints will drive heat indices to around 108-112° inland and approaching 116° closer to the coast. This has prompted an Extreme Heat Warning for Charleston and southern portions of Berkeley County (Hanahan, Daniel Island) along with an expansion of the heat advisory inland to the rest of Berkeley and Dorchester counties from 11am-8pm. Get plenty of hydration and be sure to take frequent breaks indoors or in the shade if you are working outdoors during the heat of the day!

Expect showers and storms to kick off in the noon-2pm timeframe. Slow-moving storms are again expected, with the potential for training of rainfall over some of the same areas, yielding some heavy rain and perhaps a few more flood advisories. Lightning will also be prevalent once again, so be ready to head inside if thunderstorms approach. It won’t rain all day at any one spot, though.

Friday & the weekend: Dangerous heat wave begins

/ July 24, 2025 at 8:39 PM

Anomalously strong high pressure builds in aloft starting Friday, bringing about the hottest weather of the year. We’ll challenge record high temperatures as well as record warm low temperatures, with heat advisories and even Extreme Heat Warnings a likelihood.

Thursday: Scattered storms possible, but taper off ahead of a hot weekend

/ July 23, 2025 at 8:54 PM

The stationary front that’s been lingering nearby will begin to fall apart on Thursday as high pressure begins to build in, bringing storm chances down and temperatures up especially as we head into the weekend, which looks particularly hot.

Friday & the weekend: Heat turns up a notch; advisories possible

/ July 17, 2025 at 10:57 PM

The story for Friday and the weekend will be the potential for dangerous heat as high pressure ridges in overhead and at the surface while dewpoints continue to run in the low-to-mid-70s, helping to keep overnight lows elevated to near record-warm levels and storm chances suppressed, worsening the risk for heat stress as a result.

Thursday: Storm chances decrease, heat starts to build

/ July 16, 2025 at 6:11 PM

Storms will be more hit-or-miss on Thursday as high pressure aloft starts to rebuild, which will heat things up for the weekend. Temperatures will start in the mid-to-upper 70s, with lows possibly not getting below 80° at the beaches. We’ll warm to the low-to-mid-90s in the afternoon, and with limited storm coverage, heat indices should have no trouble getting into the low-to-mid-100s, especially post-seabreeze.

Friday & the weekend: A little hotter, a touch less stormy

/ July 10, 2025 at 8:19 PM

We should see more thunderstorms on Friday as mid-level energy continues to affect the area for one more day. High pressure then ridges in aloft for the weekend, warming temperatures up and taking storm chances down a notch.

Friday & the weekend: 90s continue with a few storms each afternoon

/ June 26, 2025 at 6:05 PM

A fairly standard summer setup will take shape for Friday and the weekend as high pressure in the Atlantic ridges westward across the area, keeping temperatures warm and humid with daily storm chances. We can generally expect temperatures to start in the mid-70s each morning, with temperatures warming to the low to mid-90s each afternoon as our run of 90° days dating back to June 14 continues. Dewpoints ahead of the seabreeze will mix out with some drier air aloft to keep heat indices from getting too far out of hand, with apparent temperatures running just 3 or 4° warmer than air temperatures. Still, if you have vulnerability to the heat, be mindful of too much strenuous activity during the afternoons.

We should see isolated to scattered showers and thunderstorms fire along and ahead of the seabreeze each afternoon. The risk for severe weather is very low, but there’s always the risk for a storm or two to briefly turn strong to severe especially where thunderstorm outflow boundaries collide. Remember, all thunderstorms are dangerous because of the lightning they produce. When thunder roars, go indoors!

Thursday: Heat abates slightly, but still quite warm

/ June 25, 2025 at 6:15 PM

The high heat of the past couple days — we hit 98° again on Wednesday, just one degree off the record high — will let up on Thursday as high pressure aloft continues to weaken. Don’t misunderstand: it’ll still be plenty hot, but not to the Advisory-level thresholds we’ve hit recently. After a start in the mid-70s, likely in the wake of thunderstorms that are expected late tonight into early Thursday morning, temperatures in the afternoon warm to the low 90s. Dewpoints will mix down to around 70°, so heat indices should stay relatively tame, with a brief spike into the upper 90s possible as the seabreeze pushes inland. A few showers and thunderstorms could pop on the seabreeze, as is often the case this time of year, but nothing out-of-bounds is expected.
