MYRTLE BEACH, SC (WMBF) - The pleasant weather continues through the middle of the week with low humidity and plenty of sunshine. Low pressure developing off shore this weekend will likely bring unsettled weather and gusty winds at times.

Another fantastic day is on tap for Wednesday. Morning temperatures will start in the middle and upper 50s inland with lower 60s near the beaches. With another round of sunny skies, temperatures will climb into the lower 80s by the afternoon.

REST OF THE WORK WEEK

Thursday will see more of the same with plenty of sunshine, low humidity and temperatures returning to the lower 80s. Friday will start to bring changes as clouds increase through the day followed by increasing chances of showers by late in the day. Mostly cloudy skies and late day showers will likely keep afternoon temperatures held down into the middle and upper 70s.

LATE WEEK LOW PRESSURE

The forecast from late Friday into the weekend remains very complicated as an area of low pressure develops off shore. The strength and movement of the low pressure area will have impacts on the weather here at home through the weekend.

The low pressure will develop late Thursday and continue grow a bit stronger by Friday and Saturday.

With water temperatures off the coast being above 80°, there’s a slight chance the low pressure area could begin to take on some tropical characteristics. Right now, the National Hurricane Center has the risk of any tropical development at just 30%. Thankfully, there is no data that suggests this would become a powerful or disruptive tropical system.

Showers become likely late Friday through Saturday.
