    I'm pretty sure the gust of 93mph at Camp Creek overnight was the highest ever recorded at that station...unless I'm forgetting something. I think the previous record was 92mph. I'm certain there were other stronger events (2004 was the strongest I can remember), but there weren't reliable data at that point.

    Great video. Thanks for sharing. Hopefully you enjoyed your trip.

    That's the best area. I usually go to the church parking lot that is next to the Camp Creek Memorial. It is next to the school. I like that spot because it gets me away from trees and power lines.

    Keep us posted. Have you been there before?

    Camp Creek is already getting gusts to nearly 70mph this morning. I actually think this Mountain Wave event is slightly more favorable for Camp Creek than the previous system.

    It looks like the mountain wave event is underway. Just noticed a 60mph gust on a weather station in southern Greene Co. I'm actually keeping an eye on areas west of Camp Creek too. On rare occasions, that area can get wind gusts that rival what is experienced at Camp Creek Elementary for a particular event. Unfortunately, the data in that area aren't as reliable. That includes areas like Cedar Creek and St. James. The roof has been blown off the gym at South Greene HS a few times, so these windstorms aren't isolated to the Camp Creek community. This event might actually favor areas just to the west of Camp Creek...but that's just speculation on my part. Regarding your question, I still believe the effects of the mountain waves will extend away from the foothills in a few areas, and it could cause tree and power issues. It's difficult to pinpoint where. It's common to have 70mph wind gusts in one area while winds remain relatively light just a few miles away. The LLJ is extremely strong tonight and other parameters are favorable, so it's hard to imagine there won't be some very high gusts recorded.

    Yes, this could be a very impressive event. I need to give credit to MRX for their great afternoon discussion regarding this. I completely agree with everything they wrote, and I actually agree that the mountain waves might extend a little further away from the mountains than usual.

    The potential is definitely there for significant wind event. When HRRR wind gusts look like that, it’s usually a pretty good indication of a high-end event. Even the high-resolution models typically underestimate wind potential with these events, specifically for places like Cove Mountain and Camp Creek. Hopefully we can avoid any major fire issues.

    The Tweed fire near the Cocke County/Greene County line is showing up pretty good on satellite this evening. Hopefully they can make some progress with that fire in the short term. Wind might become more of an issue for that area by midweek as a southeasterly flow gets established over the mountains. It shouldn't be a significant wind event (the 850mb flow is pretty weak) but it could create some breezy/windy conditions. That area isn't as bad as Camp Creek, but it still gets some significant downslope enhancement with southeasterly flow. You can see signs of the potential enhancement over that specific area on model output.

    I was thinking about that earlier today, in terms of where this rainfall total ranks for me. I ended up with just over 6.00 inches today. It caused several flooding issues across Greene County today. Schools are closed tomorrow...it would have been their first full day. It's definitely one of the largest one-day totals that I can remember. My largest total by far occurred at the same time of year in 2001 (August 3&4). I had over 14.00 inches of rain with that event, but it was actually worse in other areas. I really wish there was a reliable rainfall total from the max area in that 2001 flood. The NWS wrote this a few weeks after the event "An unofficial gauge at Viking Mountain, located approximated 7 miles southwest of the radar-indicated maximum, measured 15.35 inches from Friday evening until Saturday morning". That was probably one of the top 5 most memorable weather events that I've experienced. It was unbelievable how hard it rained for about 4 hours that morning. Today's flooding doesn't compare to that, but it is still a notable event.

    Up to 5.53 now.
  12. Math/Met
    My rain gauge has 4.60 inches so far today in Greeneville. Still pouring.

    I'm a little late posting this. This is a picture from the Greeneville Sun newspaper. The roof was blown off a double wide mobile home in southern Greene County (Camp Creek area).
  14. Math/Met
    Just noticed that as well.

    Just to follow up on this. I haven't looked to see how bad it was in other areas, but I don't really consider 78mph to be a particularly strong mountain wave event for Camp Creek. This type of system (the evolution and orientation of the LLJ)has underperformed several times at CC in my years of studying them. That's why I was kind of reluctant to go all in on a high end event. Still a decent mountain wave event though.
