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.
Near-normal temperatures and a few stray storms will mark Juneteenth across the Lowcountry. We start the day around 70°, warming to the upper 80s in the afternoon as onshore flow continues to keep temperatures a little lower. A few showers and maybe a thunderstorm will be possible, particularly in the afternoon, but many of us stay dry once again.
An approaching tropical wave — thankfully, of the open wave variety and nothing more organized — will be the weather feature of interest later Thursday into Friday. Ahead of the wave, we should see a mostly quiet day of weather with temperatures near normal and partly cloudy skies. Rain chances tick up Friday as the wave comes ashore, with scattered showers and thunderstorms a decent bet. It won’t rain all day at any one location, though. Temperatures Friday will be limited to the upper 80s with the shower and thunderstorm activity. We’ll start to get much warmer this weekend, with highs returning to the low to mid-90s well into next week.
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.
The week ahead will generally feature temperatures around if not even a touch below normal at times through mid-week before warming back up, perhaps into the mid-90s, for the weekend.
We start the week off fairly quietly as a little bit of lower-dewpoint air nudges into the area, generally capping highs in the upper 80s to around 90°. High pressure aloft and at the surface will keep thunderstorm chances very low, so expect to at least get the first couple days of the week in rain-free.
High pressure starts to weaken as we head into Juneteenth, and the standard summertime afternoon thunderstorm chances respond accordingly. Storms could be a little more widespread Thursday as low pressure approaches Florida, enhancing the flow of moisture into our neck of the woods. A warming trend begins Friday as high pressure offshore moves a little further south, turning the resulting flow at the surface more southerly as well and essentially turning the heat pump back on. Low-to-mid-90s temperatures are expected Friday through Sunday, with scattered thunderstorms each afternoon.
Heat continues to build into Saturday before onshore flow knocks thermometers down a few clicks starting Sunday. After starting the day in the low 70s, temperatures should head to the mid-to-upper 90s in the afternoon especially away from the coast. A few thunderstorms are possible in the afternoon as the seabreeze moves inland, which may offer some relief, but otherwise, be ready for a hot day that’ll feature heat indices over 100° at the height of the afternoon. Take frequent breaks in the shade and with plenty of water if you must be outside.
Winds turn more onshore Sunday, which will make it a little more humid but also “cooler” (technically, 91° is cooler than 97°), though heat indices will peak in the upper 90s so it all comes out in the wash. A few storms will be possible along and ahead of the seabreeze once again in the afternoon, but a rain-free day is quite possible for many of us. Just be ready to bring outdoor activities inside in case a storm threatens your location.
