Tuesday’s forecast looks relatively benign across the area as partly cloudy skies dominate thanks to increasingly drier air aloft. We’ll start the day in the low 70s away from the coast before highs top out in the low-to-mid-90s in the afternoon. Heat indices should top out in the low 100s with low-70s dewpoints across the area. A shower or storm can’t be ruled out along the seabreeze, but most of us should get Tuesday in rain-free.
Believe it or not, it’s already the last full week of July. Climatologically speaking, this week’s forecast is about as end-of-July as it gets: Mid-70s lows each morning, low 90s highs each afternoon with isolated to scattered afternoon thunderstorm chances as the trough that made Sunday in particular quite unsettled lifts out and ridging begins to build back in.
Monday could offer up some slightly better shower and storm chances during the day as a little spin remains in the atmosphere, but a repeat of Sunday’s deluge (more on that in a minute) is certainly not in the cards with generally scattered coverage expected.
Mid-week will feature highs generally 92-93° with a few seabreeze showers and thunderstorms each afternoon in a very standard summertime regime with Atlantic ridging firmly in place. If anything, that will get even a little stronger as we head into the weekend; temperatures will respond appropriately by heading back into the mid-90s on Saturday and upper 90s on Sunday. Dewpoints won’t quite be as nasty as they were this past week, but low-70s dewpoints should still yield a period of heat indices 104-106°.
Best risk for new flooding is shifting into Summerville and Goose Creek as thunderstorms push inland. Rain rates around Park Circle have mercifully come down. Please send any flooding reports!
