Why This Forecast

NWS ILM Analysis

Issued Jun 28, 7:36 PM

Tonight you've still got a 42% chance of showers and thunderstorms before things clear out by morning. That's the tail end of a trough, that's a dip in the upper-level pressure pattern, pushing through this evening with a cold front attached to it. Once that system moves offshore by midnight, you'll be clear for the rest of the night. Monday shapes up hot and sunny in Myrtle Beach, only 19% chance of any storms, with highs pushing toward 88°F.

What's actually happening is a frontal boundary that's moving south and stalling right around the coast by Monday or Tuesday. As it stalls, low pressure is expected to form along that front, and here's the interesting part: that low could develop subtropical or even tropical characteristics as it drifts westward through mid-week. The National Hurricane Center is keeping a close eye on it, though right now the risk to you is low. Meanwhile, high pressure is building in from the north behind the cold front, which'll give you that clearing and the start of a heat buildup.

Looking ahead, you're entering a serious heat pattern. By mid-week, heat indices are forecast to climb into the triple digits as that high pressure stays parked over the region. The National Weather Service is already discussing the possibility of Heat Advisories by Thursday and Extreme Heat Warnings by Friday or Saturday, especially in coastal areas. So enjoy the relatively pleasant Monday and Tuesday—you're about to get a taste of what summer really means in the Carolinas.
