could just be a scuddy updraft hard to say, but there does seem to be a fairly defined funnel there for 20-30 secs.....
I think it's a look-alike -- a scud cloud forming on the gust front. There's no discernible rotation.
I'm getting very heavy rain now -- no lightning or thunder.
Northern Pitt Co has been hammered, and now the line is over Greenville and barely dropping south while new storms fire and move east, going to get 2-4" in town easy if this holds up, should see flash flood warnings for Greenville proper soon. Also a general area of rain and storms firing back to the west headed this way as well.
I posted my video to mhx Facebook page and they said it was a gustnado forming under the leading edge of the squall line.
What exactly is a gustnado? I've heard the term before but not familiar with what it is. I could see some rotation in the video you posted. Had the same thing move right over my house today, could actually see clouds rotating but it was very broad and weak. So far it doesn't look like any damage which is good.

Several interesting points on Wikipedia. The one I got the video of does go from ground to cloud base.
The cool air in the gust front acts like a mesoscale cold front. It slices under the warm air ahead of it, creating upward motions and turbulent interactions. The friction from this interaction creates a spinning column of air, or eddy, which can create a gustnado (to get the general idea of this, picture an area of leaves swirling on a windy day, just on a much larger scale).
They are not considered true tornadoes (unless they connect the surface to the ambient cloud base) by most meteorologists and are not included in tornado statistics in most areas. Sometimes referred to as spin-up tornadoes, that term more correctly describes the rare tornadic gustnado that connects the surface to the ambient clouded base
Lots of quick hitting heavy showers so far, the hi res models have a more organized line of storms firing around 6-8 tonight NW of here and dropping across eastern NC I would think that will the best chance to see something severe.
Props to the hi res models for picking that line up. They nailed this system for sure.
The sea breeze is making another run for us today. It can be seen on MHX radar; it just made it to Kinston, pulling northward at 10 mph. If I remember right, it rolled right on through the Triangle yesterday evening.
It's amazing, really, what a disappointment of a weather phenomenon sea-breeze passage usually amounts to around here. It might bring a subtle backing of wind direction, but it seldom seems to change the temperature/humidity all that much, and even though it can occasionally light off convection, this far inland sea-breeze showers seldom make for anything more than the very small and fleeting.
Just something to watch on radar when you're bored, I guess.

OK, I stand partially corrected: the dewpoint took a 10-degree jump when the sea breeze hit. Other than that -- meh. A lone, stationary shower in southern Sampson County -- a half-inch for the loneliest square mile on earth.

Well it looks like we might have a cane to track soon enough, or at least a tropical storm. Models have been showing for days something developing in the BOC area and then moving into the GOM. This is a climatologically favored area for early season formation as well. Euro and CMC are both aggressive with a strong TS or cat 1 cane.

Yeah, I saw some recent Allan Huffman tweets on that:
"A trough is forecast to dig into Miss River Valley then East, during period. If system is far enough north, trough gets it turns it north. Towards US Gulf Coast. If it misses. Ridge builds in over top turns it west. And likely Mexico is threatened. Right now at 6-10 days away, very high uncertainty. But something to watch, as model consistency is noticeable."

Most likely scenario for this system is a weak, disorganized TD or TS that heads west into Mexico. However if it strengthens a little quicker it could take more of a N track towards the Gulf coast states. With the GFS and Euro now pushing this west into Mexico, I would say this is the most likely scenario to occur.
