Tropical Depression Three developed this afternoon off the Southeast coast, and will be the main driver of our weather this weekend. Even though Three is forecast to become Tropical Storm Chantal, this should largely be a beneficial system, bringing some rain to some parched spots. However, it will still bring a few hazards, including gusty winds (40-45 MPH) near the coast and offshore, a high risk of rip currents, and the potential for locally heavy rain that could lead to some flooding, particularly around the afternoon high tide. This potential has prompted a Tropical Storm Watch for Charleston County. With all that said, though, this is nothing we can’t handle.
The weather for the Fourth of July weekend looks a bit on the unsettled side as low pressure — perhaps tropical in nature — spins up offshore and increases the risk for rain near the coast.
Independence Day itself looks okay with a bit of drier air working into the area in the wake of a stalling front. There’s still enough juice for a few thunderstorms along and ahead of the seabreeze in the afternoon, so be sure you have indoor alternatives to your outdoor plans just in case thunderstorms threaten. Temperatures start in the mid-70s, warming to the low 90s in the afternoon. Heat indices will run in the mid-90s to around 100° in the afternoon, particularly in the immediate wake of the seabreeze, so be wary of the heat especially if you are more vulnerable to it.
While storms so far on Wednesday were more off than on, more chances for rain arrive on Thursday with the heating of the day and a stalling front that will be in the neighborhood. Temperatures start in the mid-70s, warming to the low 90s in the afternoon — right on the line for what to expect from early July. Showers and thunderstorms will be capable of heavy rain and frequent lightning, and an isolated severe storm can never be ruled out this time of year where boundaries collide.
