The week ahead starts out on a warm note with high pressure in play before turning more unsettled by the time we get into the weekend. Meanwhile, Hurricane Erin will be passing offshore, sparing us direct impacts but kicking up high surf, a risk for dangerous rip currents, and even some coastal flooding in the evenings.

More storms are in the offing for Saturday as a front slides southward across the area, eventually stalling out across Georgia. This front, though, brings us a slightly cooler and drier airmass that filters into the area starting Sunday.

Another hot day is ahead Friday as heat indices once again climb well into the 100s under partly cloudy skies before thunderstorms develop along and ahead of the seabreeze in the afternoon. These will be generally scattered in nature — not everyone will see a storm, but those who do could get a quick round of heavy rain and gusty winds along with a good bit of lightning.

Better storm chances arrive on Saturday as a front sags south and eventually falls apart. Many of us should see a storm on Saturday, particularly in the afternoon, with plenty of triggers available for thunderstorm development. This should also help keep temperatures pinned to around 90° — still hot, but not as hot.

Lower dewpoints move in with northeast flow behind the front, giving us a little less humidity to deal with and slightly cooler temperatures as well. Ridging aloft will persist, allowing highs to get to around 90°, while a few showers and thunderstorms will be possible on the seabreeze each afternoon. We’ll keep this going into next week, too.

Thursday will be a fairly typical mid-August day across the area. We’ll start in the mid-to-upper 70s, warming to around 90° in the afternoon with heat indices generally running in the low to mid-100s given continued dewpoints in the mid-to-upper-70s, highest downtown and along the coast with closer proximity to the water. Once again, showers and thunderstorms should fire on the seabreeze in the afternoon, and a couple of those could be on the strong side with frequent lightning and gusty winds. Winds out of the west will drive showers and storms coastward, so keep an eye on this if you’re taking a day at the beach (you lucky duck).

90° temperatures have been tough to come by so far this August. (Please note this is not necessarily a complaint.) Since August 1, only today (August 12) has been a 90° day. It’ll get a little easier to achieve the 90° mark going forward, though, as ridging aloft continues to build in. High pressure in the mid-levels helps temperatures heat up while keeping more widespread thunderstorm activity tamped down. We’ll have plenty of humidity in play, which will allow heat indices to head into the low 100s each afternoon — hot for sure, but not Heat Advisory hot, at least. And yes, there will be a chance for a few thunderstorms each day primarily along and ahead of the seabreeze (with perhaps better coverage on Friday). A couple storms could turn strong or even severe where outflow boundaries collide, and heavy rainfall is certainly a concern as well given deep moisture. However, once again, we’ve had much worse very recently, and shouldn’t have a replay of the past weekend for a bit. Just be ready to head indoors in case thunderstorms approach, and you’ll be fine.

After a rambunctious Monday that featured widespread showers and thunderstorms leading to flash flooding downtown as well as a lightning strike caught on camera in Mt. Pleasant, the weather will return to a more traditional summertime pattern beginning Tuesday as Charleston County heads back to class. Temperatures will start on the mild side, generally in the mid-to-upper 70s, warming to the upper 80s in the afternoon. Mix in the continued humidity, and it’ll feel closer to 98°. Scattered showers and storms should fire again in the afternoon along and ahead of the seabreeze, and yes, there is a risk of heavy rain with these storms, but the risk for flash flooding will be a bit lower especially as storm motions should be a bit faster.

After a dreary weekend, a more standard summertime pattern returns to the Lowcountry as high pressure ridges into the area aloft, finally breaking down the high pressure wedge and stalled front that’s kept us unsettled (but at least on the cool side).

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.

The rest of the work week will remain unsettled as the frontal zone that’s been hanging around for several days begins to trek back toward the coast, cooling us back off a little bit but keeping showers and thunderstorms in the forecast.

We remain on the cool side of normal on Tuesday, though a few more breaks in the clouds should allow temperatures to turn warmer, with highs approaching the mid-to-upper 80s in the afternoon after starting the day in the low 70s. Periods of showers and maybe a few thunderstorms will continue to be possible, though it won’t rain all the time. Some guidance suggests storms kicking off on the seabreeze later in the afternoon, which could produce some heavy downpours considering the continued feed of moisture and energy from the southwest. Severe weather is not expected, though.
