Sunday’s forecast looks fairly similar to Saturday’s: We’ll start the day in the mid-70s and head toward around 90° in the afternoon under partly cloudy skies. Heat indices will top out around 100-101°, with perhaps locally higher values closer to the coast. A scattering of showers and thunderstorms will once again be possible as the seabreeze presses inland, with heavy rain a continued concern with decent low-level moisture still in place. Ridging developing aloft will keep a lid on widespread coverage of showers and storms.

On and off showers and thunderstorms will continue for Thursday as a front remains stalled to our west and deep moisture resides over the area. We start the day in the mid-70s before highs top out around 90° before showers and thunderstorms fire. Once again, storms could pack heavy downpours that could lead to some flooding in a few spots, so be alert to quickly-changing conditions.

We have one more day of Heat Advisory-level warmth on Tuesday before a front starts to usher in changes later in the day in the way of showers and thunderstorms. First, though, we start the day in the upper 70s to around 80° in the morning before highs head back into the mid-90s in the afternoon. Mid-70s dewpoints will yield heat indices around 110° for at least a couple hours. From there, showers and thunderstorms should develop in the afternoon, with more widespread coverage arriving late afternoon and evening as the front gets closer. A few storms could be on the strong to severe side with damaging wind gusts the main concern. Otherwise, heavy rain and frequent lightning are the other main concerns.

We’re back to heat and humidity for Thursday as the brief respite of drier air comes to a close. Lows will be rather balmy — upper 70s away from the coast, likely at 80° or above closer to the coast and in Downtown Charleston — as the high temperature heads to the mid-to-upper 90s in the afternoon. Expect heat indices 105-110°, with the warmer heat indices near the coast where the higher dewpoints will be found. NWS notes a heat advisory might be needed; will keep an eye on that.

A few thunderstorms will be possible during the day Thursday as a disturbance moves by to the north. A couple storms could be on the strong side with damaging wind gusts the main concern. Not everyone will see storms, though.

After a day in which heat indices spiked to 117° at Mt. Pleasant, we should see another round of hot weather on Tuesday, though perhaps not to the extremes we saw on Monday with somewhat lower dewpoints behind a stalling front. Still, heat indices could approach 110° especially near the coast, and another Heat Advisory might be coming down the pike as a result.

Another thunderstorm complex will move across the South on Tuesday, and could bring some impacts to our nook of the Lowcountry in the evening hours. A lot will depend on how far south the front ultimately gets. For now, the best risk of severe weather looks displaced to the south of the Charleston metro, but we’ll want to keep an eye on this as the day goes on in case things change.

Thursday should be generally quiet across the metro area for the vast majority of the day as dry air characterized by dewpoints in the mid-60s — about as good as it gets at this point in the year — hang around for one more day. Expect the day to start in the low 70s once again with highs warming to the upper 80s in the afternoon. Clouds will be on the increase throughout the day as a disturbance approaches, with a slight chance of showers after sunset, but again, the vast majority if not all of us get Thursday in rain-free.

We start August with a relatively “cool” day, at least in contrast to that second half of July we just had, anyway. We start the day in the low 70s before temperatures head to the upper 80s in the afternoon. A little drier air will be mixing in, but it’ll still be humid enough to get heat indices into the mid-90s. Still, though, this is what passes for improvement at this time of year.

A few thunderstorms will be possible in the afternoon, though we shouldn’t see the high coverage that we’ve seen the past two nights. The risk for severe weather is a little lower, too.

The main fly in the ointment on Tuesday evening will be tidal flooding; high tide around 8:43 PM should top out around 7.3-7.5′ in the harbor, producing minor to moderate coastal flooding and likely causing some road closures, which were observed with Monday evening’s 7.52′ high tide. Be ready to route around flooding if you have plans downtown Tuesday evening.

The brief interlude away from the mid-90s air temperatures that have punctuated a fair bit of July will end Sunday as a tropical low and its associated showers and thunderstorms moves away. We’ll start the day in the mid-70s before highs top out in the mid-90s in the afternoon; mix in humidity and we should see heat indices around 105-106° around peak heating.

Scattered showers and thunderstorms should fire later in the afternoon into the evening hours and head coastward within northwest flow. A storm or two could get strong enough to produce a damaging wind gust or two, so we’ll want to watch that potential closely. Not everyone will see rain and storms, but if you do, be ready to move outdoor activities inside.

Standard late-July weather continues for Thursday. We’ll see primarily partly cloudy skies across the area with highs topping out in the low 90s ahead of the seabreeze. Heat indices should top out around 103° or so, with some locally higher values closer to the coast possible for a brief time as the seabreeze moves inland. Said seabreeze should be responsible for a few showers and thunderstorms during the afternoon hours, moving inland with time. Some locally heavy rainfall and gusty winds will be possible in the strongest storms, but they shouldn’t last terribly long at any one location.

Tuesday’s forecast looks relatively benign across the area as partly cloudy skies dominate thanks to increasingly drier air aloft. We’ll start the day in the low 70s away from the coast before highs top out in the low-to-mid-90s in the afternoon. Heat indices should top out in the low 100s with low-70s dewpoints across the area. A shower or storm can’t be ruled out along the seabreeze, but most of us should get Tuesday in rain-free.
