Dangerous heat and humidity continues across the Lowcountry as we get into the second half of the work week with fewer opportunities for relief from thunderstorms.

The heat wave continues Tuesday with another hot and humid day on tap, followed by a scattering of afternoon thunderstorms. We’ll start in the upper 70s inland to low 80s near the coast and downtown, warming to the mid-90s in the afternoon. Dewpoints in the mid-70s will drive heat indices toward 108-110°. Another Heat Advisory will be in effect for Charleston and Berkeley counties as a result. Further inland toward Dorchester, dewpoints should be ever so slightly low enough to stay out of Heat Advisory criteria, but it’s still going to be plenty hot.

From there, a few thunderstorms should fire along and ahead of the seabreeze. Storm motions should be a little more coastward, so keep an eye out at the beaches for possible thunderstorms. A stray severe storm is not out of the question, with damaging wind gusts and hail to the size of quarters possible.

High pressure remains the primary weather driver at the surface and aloft for the rest of the work week, keeping temperatures toasty. Northeast flow over the next couple days, though, helps to bring in some drier air, which will keep heat indices from popping off too much. Wednesday starts in the low-to-mid-70s, with temperatures warming into the low to mid-90s in the afternoon under generally partly cloudy skies. The aforementioned stacked high pressure and influx of drier air will keep convection to a minimum.

High pressure wedging southward into the Lowcountry and the resulting northeasterly flow will take a slight edge off the heat for Tuesday after another day in the mid-90s on Monday. It’ll still be a steamy start, though, and the low of 78° will get awfully close to the record warm low temperature of 79° set in 2024. We’ll warm into the low 90s in the afternoon, but dewpoints running in the low to mid-70s will drive the heat index into the upper 90s (standing in contrast to the mid-100s we’ve felt the past few days). High pressure ridging in aloft will put a lid on thunderstorm activity, though some of the convection-allowing models still try to squeeze out a few showers in the afternoon. Rain is highly unlikely, though, so don’t count on it.

Generally normal summer weather continues for the rest of the work week, with a bit of an uptick in temperature as we head into Friday and the weekend.

Standard summertime fare continues in the forecast for Tuesday with seasonably warm temperatures and a few afternoon thunderstorms. We’ll start the day on the warm side of normal ahead of a stalling cold front, with lows in the mid-to-upper 70s. The record warm low temperature at the airport for June 23 is 78°, set in 2024, and we may get close to that. From there, we’ll warm into the low 90s, but dewpoints in the low 70s will drive heat indices to around 100° at peak heating. We should see a few storms fire along and head of the seabreeze in the afternoon, though the convection-allowing models are rather sparse with coverage. If storms get going, there are some indications that a pocket of dry air in the mid-levels could help produce some gusty winds in addition to the usual heavy rain and lightning threat, so be alert for possible special weather statements or even warnings.

Unsettled weather sticks around for the rest of the work week as disturbances continue to move across the area, with a shot of tropical moisture enhancing rainfall heading into the weekend.

Heat and humidity will continue to build as we head down the home stretch of the work week. We’ll also start to see an uptick in shower and thunderstorm chances as well, which should bring at least a little relief.

Rain is done for a few days as dry high pressure builds down into the area, bringing about comfortable warmth as we get down the home stretch of the work week. It won’t feel like June on Wednesday as temperatures bottom out into the mid-50s away from the locally warmer coastline. Expect highs to peak in the low 80s in the afternoon with nearly unfettered sunshine as deep dry air sets in. Savor the low humidity because we don’t have too many more days like this left for a while!

If the beach is in your plans, be aware of a high risk of rip currents during the day Wednesday due to the ongoing northeast flow. It’s best to stay out of the water on days like this

We should see another scattering of showers and thunderstorms on Tuesday in association with a cold front that will make for a rather nice second half of the work week. Temperatures will start in the mid-to-upper 60s, warming to just about 80° in the afternoon as the front pushes further southward and drier air begins to find its way in. Dewpoints should fall nicely late Tuesday into Wednesday, setting up a stretch of spring-like conditions through Friday.
