After a rainy and windy start to Thursday, we’ll settle in to a cool and mostly sunny weekend with high pressure firmly in control of our weather.
Notable winds on Thursday morning
I heard from quite a few of you who got woken up by high winds early Thursday. You weren’t imagining things: A band of showers was able to pull down some pretty good gusts from a potent low-level jet, causing some scattered power outages and even downing a tree on the upper peninsula.
Some maximum wind gusts as reported in preliminary reports from the National Weather Service:
- Charleston International Airport: 56 MPH at 6:22am
- Mount Pleasant: 51 MPH at 6:35am
- Charleston tide gauge: 46 MPH at 6:00am
- Sullivan’s Island WeatherFlow Station: 41 MPH at 6:51am
- Johns Island (Charleston Executive Airport): 40 MPH at 6:11am
A secondary cold front will come through late Thursday, ushering in much cooler air as high pressure builds in from the northwest.
You’ll begin to notice the chill on Friday. We’ll start the day in the mid-30s, struggling to get to the mid-50s in the afternoon as cool northwest winds continue over the area despite almost full sunshine. Morning wind chills will be closer to 30°, so be sure to dress warmly if you’re out and about.
Saturday will start out even cooler, with temperatures at or below freezing in many spots away from the coast. Winds will at least back off some, but some wind chills in the upper 20s can’t be totally ruled out. Like Friday, we’ll see lots of sunshine in the forecast, but that won’t be enough to get temperatures beyond the mid-50s once again.
Once again, we’ll start out around the freezing mark on Sunday, but the resident airmass will begin to moderate a little bit, allowing temperatures to get up into the upper 50s. A nearby jet streak will enhance mid to high level cloud cover for Sunday, but dry conditions will remain in place with a very dry airmass near the surface.
Overall, things look pretty great for this weekend. Throw on a sweater and enjoy!
