cyclone77 Posted April 9, 2012 Share Posted April 9, 2012 From roughly a half an hour ago. Dual-pol variables help to visualize two updrafts just before the splitting occurs. ZDR represents the rough shape of the target, and updrafts contain liquid water in large concentrations (which should show up as positive ZDR). Two areas of positive ZDR show up, representing the two updrafts prior to the split (one north of Buffalo and the other southwest). The idea being that in the future, as we get better at recognizing these features. Two polygons could be issued, one for the left mover and one for the right. As the right mover is already diving hard out of about 300 degrees, whereas the first polygon was for a storm motion near 250. Very nice! This season will definitely be a learning experience as we get more and more opportunities to use dual-pol in these situations. Link to comment Share on other sites More sharing options...
OceanStWx Posted April 9, 2012 Share Posted April 9, 2012 Big time echo overhang on that cell. Surely producing significant hail, however the inflow is about to be disturbed by the cells to the southwest. Probably going to limit tornado potential for at least the next several volume scans.

cyclone77 Posted April 9, 2012 Share Posted April 9, 2012 About 100kts g2g in the 9000-13000ft range. Spinning like crazy aloft. Link to comment Share on other sites More sharing options...
OceanStWx Posted April 9, 2012 Share Posted April 9, 2012 About 100kts g2g in the 9000-13000ft range. Spinning like crazy aloft. The storm farther southwest, northwest of Woodward, actually has a very well defined mid level meso too. Has just as much potential I would think. Maybe not as close to the warm front, but probably has outflow from the northern cell to act as a pseudo-warm front. Link to comment Share on other sites More sharing options...
SouthernNJ Posted April 9, 2012 Share Posted April 9, 2012 The storm approaching Woodward is potentially concerning, because if it strengthens, it will move into a populated area. Link to comment Share on other sites More sharing options...

OceanStWx Posted April 9, 2012 Share Posted April 9, 2012 They are right on the nose of the theta-e ridge, with a really sharply defined boundary providing plenty of low level vorticity. Couple that with steep low level lapse rates you have enough 0-3 km CAPE to stretch that in the horizontal. Link to comment Share on other sites More sharing options...

David Reimer Posted April 9, 2012 Share Posted April 9, 2012 The tornadic potential with the two supercells near Woodward will depend greatly on their potential to contain surface outflow. So far I have not seen any reports of defined low level circulations being reported by spotters. Remember that the VNX radar is looking upwards of 8,000 feet.

cyclone77 Posted April 9, 2012 Share Posted April 9, 2012 At 2135 KWWR has south-southeast 36, gusting to 44mph. Nice surface inflow into that Woodward cell. Link to comment Share on other sites More sharing options...

Hearing reports of a lot of dust being loft by the inflow, and CC bears that out with low values in the inflow region. Link to comment Share on other sites More sharing options...

OceanStWx Posted April 9, 2012 Share Posted April 9, 2012 110kt g2g west-northwest of Woodward at around 6500ft. That kind of meso has to be producing something larger than golf balls. I would say we're pushing tennis balls at this point. Link to comment Share on other sites More sharing options...
