We get a brief reprieve from the heat on Tuesday as the front that brought today’s deluge nudges just south enough for a little bit of cooler and drier air to work in, especially further inland. Mostly cloudy skies will be the rule as onshore flow persists throughout the day. We start the day in the low 70s, but dewpoints sneaking briefly back into the upper 60s could feel a little bit better than we’ve felt. Those dewpoints will start to creep back up, but the cloud cover and onshore flow keeps highs capped to the mid-80s. A stray storm can’t be totally ruled out near the coast; in fact some model data suggests a few downpours will be possible before sunrise. Wait and see on that, but most of us should get Tuesday in rain-free.

It was a nice couple days of heat indices “only” in the upper 90s to low 100s, but we return to Advisory-level heat on Sunday as air temperatures in the mid-90s combine with dewpoints in the mid-to-upper 70s to yield heat indices 108-110°. Once again, you’ll want to be sure your outdoor activities involve frequent breaks in the shade with plenty of water.

Those outdoor activities may become disrupted as we get into the afternoon and evening hours as thunderstorms begin to fire along and ahead of the seabreeze. Coverage should increase as the evening goes on as a disturbance aloft swings by. Scattered to numerous showers and thunderstorms will be possible with some periods of locally heavy rain and cloud-to-ground lightning. A few stronger storms could produce sporadic damaging wind gusts, so be alert for possible severe weather warnings as well. Regardless of the severity of the storms, lightning makes every thunderstorm dangerous. If you can hear thunder, you’re close enough to be struck by lightning, so move those outdoor activities inside if a thunderstorm approaches your location. Most of the activity should disperse as we get later into Sunday night, though some could hang around with the energy aloft and an approaching front.

We’ll want to keep an eye on Monday for the potential for some flooding as slow-moving showers and storms should fire on that aforementioned front as it stalls out across the area. I’ll have more on that risk tomorrow as more data rolls in.

The meteorological status quo continues on Thursday: Heat, humidity, and a few storms in the afternoon. Temperatures will be fairly heinous on Thursday, with lows barely dipping below 80° away from the warmer coastline and highs getting into the mid-to-upper 90s in the afternoon. Mix in dewpoints in the mid-70s, and that’ll yield another day of dangerous heat indices in the 107-110° range. I’d be ready for yet another Heat Advisory to be issued for tomorrow.

A front sinking southward into the area combined with the usual seabreeze influence will help improve shower and thunderstorm chances for more of us tomorrow afternoon and evening. Pockets of heavy rain will be possible, and some gusty winds will be possible in any thunderstorm as well. A stray Severe Thunderstorm Warning certainly is in the cards, but widespread severe weather isn’t expected.

Another hot summer day lies ahead for Tuesday, with just a few of us possibly seeing some relief from thunderstorms in the afternoon. We start the day in the mid-70s, warming to the mid-90s in the afternoon. Dewpoints in the low to mid-70s will make it feel closer to 103° at times, with even warmer heat indices possible in the wake of the seabreeze.

As mentioned, a few thunderstorms will be possible with a stalled front in the area, but not everyone will see a storm. A stronger storm or two can never be ruled out this time of year, but there is not a widespread risk for severe weather.

Thursday looks to remain mostly quiet over the area, though a few showers will be possible near the coast once again during the morning as showers within onshore flow reach land and dissipate in drier air. We start the day around 70° and warm to the upper 80s in the afternoon, much like the past few days. If you’ve been enjoying the somewhat lower-humidity mornings that we’ve had lately, enjoy this tomorrow morning because we’re shifting back into more traditional mid-to-late-June dewpoints starting Friday.

We’ve got one more generally quiet day of weather coming up for Tuesday before turning a little more unsettled heading into the second half of the week. Temperatures will remain around if not a touch below normal as a solid onshore breeze keeps us on the “cool” side. We’ll see a few clouds from time to time, but overall, expect a mostly sunny day. The only downside to the onshore flow will be a moderate risk of rip currents at the beaches, so be alert if you are going to be heading into the surf.

Thursday could feature a few showers and storms brushing the coast as low pressure tries to organize along a stationary front that’s been lingering offshore for the past few days. It’ll otherwise be a fairly standard warm June day — lows in the low 70s yielding to highs around 90° in the afternoon under a mix of sun and clouds. Dewpoints in the upper 60s will help keep heat indices from getting too far out of hand, thankfully.

It’s a low bar to clear, but Tuesday will be much quieter than Monday was weather-wise as drier air noses in from the northeast. This should be enough to keep storms, much less significant cloud cover, at bay for a day. We start the day in the upper 60s to around 70°, warming to about 90° in the afternoon under mostly sunny skies. Unfortunately, we’ll need the good weather for some cleanup after severe storms brought large hail and damaging winds to the Summerville area on Monday evening.

Humidity continues its slow climb on Sunday as onshore flow from the Atlantic gradually sends dewpoints higher. Most of us should stay rain-free, though some guidance does show the potential for a few showers to brush coastal areas in the morning. There’s also the risk for a few popup storms generally near I-95 in the afternoon, but the vast majority of the Charleston metro stays rain-free.

Temperatures head to the mid-80s after a mid-60s start. As alluded to earlier, dewpoints will continue to creep upward, generally remaining in the low 60s. This’ll yield relative humidity values generally in the 45-50% range — still far from horrendous, but you might notice a little more sweat.

A dry front is getting through tonight, and that will open the door for a really pleasant ending to May. Temperatures start in the low-to-mid-60s, which is a few degrees below normal for May 30. We’ll warm to the mid-80s in the afternoon under mostly sunny skies, right near climatological norms for this point in the year. Dewpoints will mix out to around 50° during the day, which should keep the warmth more on the comfortable side than not.
