cstrunk Posted June 19 I agree with SPC concerning the tornado threat, my concern is for potentially wind-driven very large hail. That would be no fun. *edit - Towers are going up north of DFW. Initiation seems likely soon. Quote Share this post Link to post Share on other sites

Wmsptwx Posted June 19 AR storm is very impressive. Quote Share this post Link to post Share on other sites
Jim Marusak Posted June 19 could it be held up by the CI/AS layers currently in most of the metro from the storms off to the SW near Brownwood/Abilene/Dyess AFB (extrapolating from the ASOS cloud heights and satellite pics there attm). it also looks like two sets of the blowoff tops may have caused a bit of a bubble to form in between, with that bubble right on top of the metroplex.

Chinook Posted June 20 Rotation seems to be pretty noticeable near Como and Sulphur Springs, TX. Quote Share this post Link to post Share on other sites
Jim Marusak Posted June 20 00Z RAOB from FWD. just an ever so slight lid still holding attm, especially if you look at the mixed layer, not the pure surface Td. still though 3900 j/kg cape and an LI of -12. just need to bust the cap at 750hPa. the lapse rate from the lid to 500hPa is big though, so pop it, and you'll need more than the Coyote's parasol to protect you from the hail.

Bob's Burgers Posted June 20 HREF probs look pretty impressive this evening in the Central Plains. Depending on how robust these storms are could have major implications for tomorrow's event. Quote Share this post Link to post Share on other sites
andyhb Posted June 20 That is an impressive shortwave coming through the S Plains for the end of June on Sunday. Setup looks more May-like synoptically. 1 Quote Share this post Link to post Share on other sites

Jim Marusak Posted June 21 quick question on this double squall line moving through eastern KS and Missouri currently. How close can these lines be before they end up working against each other in a dynamically destructive manner? Quote Share this post Link to post Share on other sites

It's Always Sunny Posted June 23 On 6/21/2019 at 9:45 AM, Jim Marusak said: quick question on this double squall line moving through eastern KS and Missouri currently. How close can these lines be before they end up working against each other in a dynamically destructive manner? I'm not sure my answer is 100% correct but from my experience it is more about the timing than the distance apart. What I mean by timing is how long it takes for that second line to pass through the same environment the first line did. Generally that second line would weaken as it pushes east due to the fact of the first line eats up all the moisture and instability ahead of it. However, looking at previous models it was ridiculously unstable across that geographic area when those two lines passed through to where it would be hard for that first squall line to work over the atmosphere enough. Those lines were also moving really fast so it's not like that first line had time to work over the atmosphere enough either. Also the LLJ was very strong which definitely fueled those lines. Personally, I would consider this event an anomaly. I'm sure other mets can correct me or add onto this but I hope my explanation helps a bit at least!

nrgjeff Posted June 25 Back on Friday the double squall line or double MCS was able to survive because both had open access to the LLJ and inflow. They were moving somewhat in parallel, instead of one immediately following the other. Eventually they somewhat merged in the Ohio Valley before continuing through the Tennessee Valley and off the Carolina coast. @Jim Marusak @It's Always Sunny The MCSs were impressive. 1 Quote Share this post Link to post Share on other sites
