Drove from Hickory to Knoxville this morning, leaving Hickory around 10 AM. Never got below freezing in Hickory - a total nothing-burger. Was 35 when I left. Temp fell slowly as I drove west. Ice began to show in the treetops once I got west of Marion. Coldest temp observed was 33, right at the top of Old Fort Mountain. Trees were all glazed over all the way up the mountain. It was quite beautiful. By the time I got to the Swannanoa exit about 7 miles away, the temp had risen to 40 and the sun was peeking through. Just an amazing demonstration of cold-air damming in action and how different the weather conditions can be on either side of the Ridgecrest pass at the top of Old Fort Mountain. High temp on my drive was right around the NC state line where it got above 50! By the time I reached Knoxville, it was drizzly and back down to low 40s again. Weather is truly interesting as it changes due to geography, and sometimes it’s the opposite of what you would expect.
