MYRTLE BEACH, SC (WMBF) – High pressure builds in tomorrow which will bring in warmer temperatures with plenty of sunshine this week. For church goers this morning, you’ll definitely would want to grab a jacket. We start off the days with temperatures in the mid to upper 30s with cloudy skies. Thanks to the cloud cover and northerly winds our high temperatures are going to struggle to get out of the 40s today. Looks like a good day to stay inside and read a book with this type of weather.
