A weak cold front drops south through our area overnight. This brings the first hit to our temperatures. Overnight, we drop into the 50s with partly cloudy skies. Then temperatures only warm to highs in the low to mid 70s under a mostly sunny to partly cloudy sky with cloud cover increasing into the later part of the day. If you’re heading to the beach, scattered showers are already be underway in the morning. The rain tracks inland as a coastal low pressure system begins to curve toward the coast of the Carolinas. Showers are not expected to advance much farther than the Midlands by the end of Friday.

Saturday and Sunday remain First Alert Weather Days, as the low moves slightly inland over the Carolinas. For now, the early hours of Saturday look dry with rain moving in from the southeast around 10AM and becoming widespread across the area by 6 PM. Once the rain gets going, we’ll be hard pressed to see much in the way of breaks. The latest short range models do show improvements for Sunday, however. By 6 AM, the rain has move north into the northern Upstate and the mountains. The rain continues to lift north, clearing the area by 9 AM. However, widely scattered showers are still possible throughout the day, it just won’t be an all day washout. So let’s hope the models hold on to this solution!

While severe weather isn’t a concern, the potential for flooding is present. Most areas pick up 1″ to 2″ of rain which could lead to some minor issues, especially in the Eastern part of the mountains and the Eastern Upstate.

The other big issue for the weekend is the unseasonably cool weather. Temperatures take a big drop for Saturday as cool air gets pulled in on the north side of the coastal low. Highs struggle into the low 60s with many higher elevations getting stuck in the 50s. That’s about 20 degree below normal for the last weekend of May! On top of that, it’s windy, especially in the Upstate with gusts to 35 mph. Sunday isn’t much better with highs in the low to mid 60s and wind still gusting to around 30 mph. The real improvement comes on Memorial Day when the winds die down and partly cloudy skies help to warm us back up to the low to mid 70s, which is still about 5° below normal.
