The week ahead will feature what passes for a “cooldown” in mid-July followed by a return to temperatures running a few degrees above normal for this point in the year. But first, a soggy Monday as showers and thunderstorms ahead of a cold front take center stage. Some very heavy rain is possible, with another 1-2″ of rain possible across the area with locally higher amounts. We’ll have to watch for the potential for flooding as storms could train across some of the same spots repeatedly; there is also the matter of the 3:07 PM high tide to be concerned about, too, for downtown Charleston. The clouds and rain will keep highs in the mid-80s for the first time since June 23rd, so at least there’s a brief break from the heat. (Silver linings, etc.)

Rain chances continue overnight Monday, tapering off by daybreak Tuesday. Somewhat cooler and slightly drier air will be in place for Tuesday, though that may not preclude a stray shower or thunderstorm in the afternoon. Highs top out in the low 90s after starting the day around 70-71°.

A mostly sunny day appears to be on tap Wednesday with lows in the mid-70s and highs topping out in the low 90s. Dewpoints in the low 70s should yield heat indices around 100°, so while the air temperature will be a touch lower than we’ve seen recently, the humidity will make up for it somewhat.

Scattered afternoon thunderstorm chances return Thursday and beyond as temperatures warm back into the mid-90s. We may see a stretch of Heat Advisory-level warmth starting Friday into the weekend with heat indices possibly peaking near 110°; stay tuned for updates over the next few days. All in all, aside from a soggy Monday, it’ll be fairly standard July fare for us here in the Lowcountry.
