Awesome local forecast for tomorrow, has all my favorite words in it...

Breezy, with a south wind 16 to 23 mph becoming northwest in the afternoon. Winds could gust as high as 40 mph. Chance of precipitation is 80%. Little or no snow accumulation expected.

Seems likely that would tapping into that LLJ rather efficiently, gonna be a solid 40-50 mph wind along that I bet, probably last a good couple of minutes.

3k NAM is pretty outrageous with it's gusts in the morning. Pretty cool though how you can see the front and the stronger gusts south of the warm front in eastern NC

The next two frames of the NAM moves that area of 50+ gust near Marion over central and eastern NC....probably be good enough for some scattered power outages, if this was a few weeks later and the trees were all leafed out it would be worse.

Latest 3k NAM run brings the business....its overdone but some 50 mph gust seem doable over a good chunk of NC...

Ground truth this morning in the Charleston Area bears this out as verified. Winds have been over 50mph at times and multiple trucks have been overturned in West Ashley on the Wando/Don Holt bridges this morning forcing closures of the two.

Bottomed out at 992.5mb ~9am, 0.74” event total, wind gauge is sheltered but still managed to clock 26.8mph, guess is gusts were close to 40.
