Nice pics everyone! NCHurricane, thanks for sharing those looks like you had some really strong winds at your location. Possible downburst or microburst since the damage was limited to a 1 mile swath?
Thanks! That's what I'm thinking. I odd thing is that I went back and looked at the velocity scans for that time period from MHX and RAX and the highest winds aloft I saw was ~45mph. It must have been an extremely narrow corridor of winds.
How strong were the dbz? Would you be able to post a screenshot of both the radar as it moved over and the velocity? I'm curious what the presentation looked like. Definitely did some damage and had to be 60mph or higher winds to do some of that damage.

The resolution on those gifs is a little poor. If there's a certain one you want to see, let me know and I'll upload it. It seems most of the higher winds were down in northern Beaufort Co.

Hmm. Interesting. The image from 01:01 GMT shows a small area of possible weak rotation, if I'm seeing it correctly? Or maybe radar picking up on a downburst/microburst as the winds spread out in both directions?

Even though it doesn't pertain to NC I wanted to share a few pics from Preston (fountainguy97) he sent me today. They had a strong MCS roll through this morning knocking down power poles, trees and causing widespread damage. Radar indicated 70-80mph winds right as it went through Tulsa, OK where he's at for the week. Over 70k without power and it won't be fully restored until Tuesday! Here are a few pics.

I was wondering about that patch of lower wind data. It didn't make sense.

Thats what I'm thinking. At the distance from the MHX radar site and with the storm movement we had a downburst/microburst would be more likely to show up that way while not showing up very well at the mid-levels due to distance from radar. A weak tornado could also be possible if one briefly spun up and then lifted off the ground as well although that would be less likely. Any twisting of trees or limbs?

No everything was laid out in the same direction. The tree that fell and the tree top that snapped off as well as all of the limbs and debris were pretty much blown in the same direction. A shelter across the road was blown down as well in the same direction.

Sounds like a wet microburst then based on the small area of damage and radar presentation. The apparent weak rotation is probably due to the wind hitting the ground and spreading out from there. I'm guessing it probably took about 60-65mph winds to do some of that damage? Also today could have some more severe storms as well.
Rons been on vacation all week at the river. We stopped by on our way home from delaware and some storms rolled in. Had rotation on radar and watched a nice little up draft form. Of course I left to beat the storms then ron had a small funnel and developing waterspout form. I'll get the pic loaded in a few minutes.

Not sure if Tom will be able to post this or not but copied it from his FB feed. His house was struck by lightning but everyone was okay and no fire thankfully.
Wow nice pics Steve, was that from today? Did the funnel touchdown?

He didnt take that pic I did, it was down on the Pamlico River near Bayview/Ferry Landing....I couldnt see it making it to the surface and I dont think it made it......
Here is the little updraft that spawned it and there was a bit of weak rotation on velocity scans, it was also attached to the left rear flank of the main updraft and had some inflow going so I knew it had a chance. I also played with the contrast etc to get a better look at the funnel itself.

Cool site ron and his son watch during thunderstorm days. Not sure this is the same one they use but its the best one I've found so far. Shows lightning strike and the thunder wave as it races away from strike.

That is an attractive presentation, but I'm not sure how "real-time" it really is. In the U.S., unlike radar, lightning detection is privately owned and supposedly not available to the public in real time without a hefty subscription fee. (I can't imagine how that was ever allowed to happen, but never mind.) And I can't seem to make what I'm seeing on this lightning map correlate with what I'm seeing on radar, which of course is publicly owned and is in real time. E.g., a few minutes ago I saw a lightning strike depicted about 10 miles west of New Bern…but radar shows nothing west of New Bern at this time. Also, the lightning data is showing nothing (as I type this) within miles of New Bern, even though radar shows an intense echo only a few miles east of New Bern, near Grantsboro.
I once thought about purchasing a lightning subscription, but seem to recall it was a bit too rich for my blood. Given this nation's otherwise sterling level of public weather services, it's really an almost unbelievable lapse. No one's ever been able to explain or justify it to me.
