Friday & Memorial Day Weekend: Periodically unsettled, but no washout

Jared Smith / May 21, 2026 at 8:20 PM

It’s a very summer-like look to the forecast this Memorial Day Weekend as the Lowcountry sits on the fringes of Atlantic high pressure. The pattern is largely stagnant as evidenced by the copy & paste temperatures for the next few days: lows in the low to mid-70s, highs in the upper 80s to near 90°.
