OceanStWx Posted April 13, 2012 Share Posted April 13, 2012 last 9 runs of sref sig tor ingredients for manana 0z Very clear trend on that loop, and it supports the additional area of high risk. Link to comment Share on other sites More sharing options...

Memphis Weather Posted April 13, 2012 Share Posted April 13, 2012 Very clear trend on that loop, and it supports the additional area of high risk. I think its telling the values are only peaking in the 20-30 range across OK/S KS. Not that those aren't significant values...but the extreme values are clustering North. I think the idea that the most violent tornado threat (especially considering storm coverage concerns) may be shifting to NE/IA is gaining credibility fast.

Ian Posted April 13, 2012 Share Posted April 13, 2012 Very clear trend on that loop, and it supports the additional area of high risk. im sorta wondering why those areas now in high were in slight this morning. multiple models have indicated that area has pretty solid potential for a day or two.

kevlon62 Posted April 13, 2012 Share Posted April 13, 2012 We are sitting just off 81 to the north of Chickasaw and watching the SVR cell approach from the southwest. Link to comment Share on other sites More sharing options...
Chinook Posted April 13, 2012 Share Posted April 13, 2012 First cell of the day has popped SE of Chickasha Looks like that cell is already getting 1 to 2 inch hail, and headed toward Norman or OKC in 1.5 hours. It could go into classic supercell mode, but I'm not sure. Link to comment Share on other sites More sharing options...
Memphis Weather Posted April 13, 2012 Share Posted April 13, 2012 Decent DP hail signature on the cell NE of Stecker in Caddo Co per the KOUN Testbed radar. Looks like that should be the predominant threat for a while with low level wind fields marginal. Link to comment Share on other sites More sharing options...

SluggerWx Posted April 13, 2012 Share Posted April 13, 2012 I'm trying to jog my brain, has the SREF's sigtor ever hit the 50 like we see today on the 09z for 0z Sunday? That's crazy...along the same lines, do you remember the wording the week leading up to April 27 last year? I remember mention of EHI values topping to the 14-20+ range... Is it possible to see EHI values escalate north of the high 10-12 range we're currently seeing? Link to comment Share on other sites More sharing options...
Disc Posted April 13, 2012 Share Posted April 13, 2012 That cell near Chickasha looks a little suspicious. Texas Storm Chasers are showing a low hanging wall cloud and the radar is now starting to show a hook. Link to comment Share on other sites More sharing options...

It says "live data from this radar is currently unavailable". Be sure you're not checking the KCRI radar (Testbed2)...its easy to choose that one over the KOUN because they're almost on top of each other...the KCRI is NOT updating live.
