CoastalWx Posted June 29, 2012 Share Posted June 29, 2012 Definitely some slow rotation there. Like I was taught for spotter training, if you can see rotation with the naked eye it is signifcant rotation. We also teach the half way down rule for the purposes of reporting tornado versus funnel. Chances are if it is halfway to the ground it has at least some contact with the ground. So that looks dangerously close to a missed event for us, of course there have been no reports of damage either. That's the trouble with the "cold-air" funnel/landspout days, you don't necessarily need lightning or even 50 dBZ to get something to briefly touch down. I pretty feel the way you do and said that to my friend. I didn't even think it was that questionable after a second look. Link to comment Share on other sites More sharing options...

OceanStWx Posted June 29, 2012 Share Posted June 29, 2012 We've got our first good looking cell going up now in northern Coos County. Two volume scans and it's now pushing 50 dBZ to 25 kft. Link to comment Share on other sites More sharing options...
OceanStWx Posted June 29, 2012 Share Posted June 29, 2012 Nice lean to the updraft on the first pulse, plenty of shear out there. Core came down a bit on the last volume scan, but I think it's just working on what's left of the capping. Link to comment Share on other sites More sharing options...

If only there was a LLJ to aid in forcing that MCS could be putting down widespread 100+ mph wind. Link to comment Share on other sites More sharing options...

Yeah, though I wouldnt be surprised to see a few more reports get close to that...particularly where the commahead/meso low area really comes together in the next few hrs Link to comment Share on other sites More sharing options...

CoastalWx Posted June 29, 2012 Share Posted June 29, 2012 I miss when a conditional slight risk can turn into that. Well maybe we can grab something interesting, if the models are right and another heat plume tries to move in next weekend. We really need to get into it a little more and not be on the periphery like we are now. There is obviously a narrow window for severe as you don't want to be in a position like the good folks in TN are. Link to comment Share on other sites More sharing options...

There probably will be a nice event over the next few days, if only because I'll be heading to the heart of the heat ridge down in NC. Link to comment Share on other sites More sharing options...
