    June 13-30 Severe weather

    that makes total sense. and yes they were impressive. not something you or I will see very often. just hope i remember the mental notes for the next time it happens, say in like 10 year or so.

    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?

    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.

    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.

    MAY 20, 2019 High Risk

    on the SPC site, just saw the 00Z soundings at OUN and FWD, and those look a lot more promising now for all modes of severe weather with a bit of a more stereotypical severe weather lid forming aloft. add to that the height falls now coming in from NM with an approaching upper low on the mid-level WV satellite (channel 9), and now we're going to get to business for eastern OK and beyond, imho. the high risk may end up verifying yet, or at least has a better chance now. just a more dangerous setting in the night.

    MAY 20, 2019 High Risk

    i'm not calling it a bust by any means. was it in the storm mode everyone was hoping for in the OKC metro and SE OK? no, too tropical below 650 in the warm sector. but Jackstraw is right in that we're getting to the time in the evening and into the night where the near-surface layer isn't as important and the LLJ kicks in. And from that 21Z sounding I pointed out earlier for OUN, there's still enough kinematics and instability aloft to do a lot. It will be interesting to see the 00Z soundings from OUN, MAF, and FWD as well as any special soundings if they were to put them up out at ABI and maybe SPS to get a better pic of the air masses moving in for the overnight.

    MAY 20, 2019 High Risk

    going based off the obs, I would say Swisher County Tx > Altus OK > Minco OK > downtown OKC > Cushing OK > Nowata Conty OK with a first guess

    MAY 20, 2019 High Risk

    anyone look at the 21Z sounding from OUN (18Z and 21Z sounding pages linked below)? If you did, maybe you could see what's actually the problem in the OKC metro and SE OK attm. it actually looks like the moisture may have been way too deep to really get anything explosive going. very moist sounding from the surface to 650hPa. A lot of CAPE there, but the lower 1/3 of the troposphere almost looks purely tropical, IMHO. And tropical air masses aren't as tornado-prone as more traditional storm soundings. Not saying we won't get massive downpours with that, because we most certainly are, and will see that. And not saying that you can't get anything rotating with it, because we are seeing it in spots. But normal tornadic air masses with the normal V at the bottom this is not. https://www.spc.noaa.gov/exper/soundings/19052021_OBS/ https://www.spc.noaa.gov/exper/soundings/19052018_OBS/ something closer to traditional would be the sounding at KAMA at 19Z, if you mix out the surface. https://www.spc.noaa.gov/exper/soundings/19052019_OBS/ thoughts on this observation?

    better look reflectivity and velocity from KFDR radar, tornado now on the ground, Mangum, OK.

    Central PA Spring/Summer 2019

    a friend of mine over near Shickshinny Lake in rural Luzerne County PA actually posted a pic up of hail near ping pong ball sized hail with the cluster that moved through Luzerne County near 8p EDT, with a bunch of quarter-sized still in the yard after 20+ minutes of melting time. Also, in the City of Nanticoke on the other side of the river, I saw a bunch of friends who put up pics of tree damage (some pretty big and healthy ones) from the first cluster of storms a couple of hours earlier, with power out in several sections of the city. hopefully they all took my instruction and reported the pics and the hail/damage to the NWS in BInghamton, but we'll see in the final records. the radar was actually looking decently impressive by eastern PA standards this afternoon.

    that's the same cell that has been going from McCook to Cozad, that's just a "hand-off" warning for North Platte as the cell moves across CWA's.

    and Cozad is about to get hit with another circulation, and possibly a 2nd tornado. not exactly their night for viewing only.

    at least I'm not the only one. because yea, you're right they're usually the result of cell mergers and are short-lasting due to outflow disruption, allowing for one dominant cell and circulation to take over. these cells being the formation they are just seem unusual to me. I wonder what type of data the researchers are getting out there today on those cells.

    Mid to Late May 2019 Severe Threats

    question here. maybe i just haven't seen enough of them due to work or something. but there seem to be more than the usual amount of "multi-core" or "multi-circulation" supercells today than usual. the one that formed near Ft Stockton and is still going to the east on I-10, and the one currently in Nebraska crossing I-80/US 30 between Gothenburg and Lexington. the ones I have seen the most are usually single core-single circulation. is it just me?

    one curious thing, looking from the Hastings radar. you have one storm just departing the 88d near Goodland, and one moving on top of the LNX/LBF radar near Thedford. both getting direct hits within minutes of each other. good thing they're engineered well. would hate to see the areas west of US go low-level radar blind from both radars at once
