Memorial Day across the Lowcountry, while not nearly as springlike as last year’s, will feel appropriate as the unofficial start of summer. We’ll start the day in the low 70s away from the locally warmer coastline, heading into the upper 80s to near 90° away from the beaches by afternoon before the seabreeze rolls through. Temperatures at the beaches will top out in the low to mid-80s, making for a really good day to get some sun. (Just mind the high UV index and apply sunscreen liberally!)
There’s a tiny chance we could see a shower or storm in the morning as a little energy ripples on by, but that risk is rather low. The better — albeit still slight, all things considered — chance for showers and maybe a thunderstorm comes in the afternoon as we reach peak heating along and ahead of the seabreeze. Winds are onshore throughout a good bit of the atmosphere as surface high pressure remains offshore and a 585-588 decameter ridge remains centered over eastern North Carolina, so this should allow for the seabreeze to make good movement inland throughout the afternoon, limiting the risk for any thunderstorms near the beaches especially after 2PM. With limited to no wind shear to work with, thunderstorms will be pulse in nature and thus pop and subsequently collapse. All this to say, though, that the risk of any one location seeing storms is quite low — just be sure to have an indoor backup plan in case it’s needed briefly. Remember: When thunder roars, go indoors!
Temperatures will fall into the mid-70s in the evening, and any showers should be long gone by the time Nduduzo Makhathini takes the Cistern stage at Spoleto tomorrow night.
Finally, don’t forget to take a pause tomorrow to honor those we’ve lost in combat and their families. That’s why a lot of us are off, after all.
