Hoosier Posted May 11, 2011 Author Share Posted May 11, 2011 Today was about as unstable of a mid-May day here as I can recall. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted May 11, 2011 Share Posted May 11, 2011 Today was about as unstable of a mid-May day here as I can recall. agreed, 4500 j/kg of MLCAPE and an LI of -11 by noon is quite impressive and something I've never seen. Link to comment Share on other sites More sharing options...
OceanStWx Posted May 11, 2011 Share Posted May 11, 2011 I thought of two days immediately when I saw this with one being the Roanoke day that Hoosier mentioned and the other being 8/4/08 from DVN and ILX roab soundings with the 2nd one from ILX just huge....the most I've ever seen, amazing. My first day of work at DVN, I remember I came back in to assist with the evening launch and comms. I remember wondering what I got myself into when the temps around 00z were close to 85/80. Funny though that 6/18/09 immediately popped into my head when I saw the question, despite this sounding having the higher CAPE values. Link to comment Share on other sites More sharing options...

Hoosier Posted May 11, 2011 Author Share Posted May 11, 2011 I still can't get over that Bangladesh sounding. What would a warning look like? ...RADAR INDICATED A DANGEROUS SEVERE THUNDERSTORM CAPABLE OF PRODUCING VIOLENT TORNADOES AND BASKETBALL SIZE HAIL...

Chinook Posted June 1, 2011 Share Posted June 1, 2011 I used to have a web page about this, and I still have the files on the internet. 7150 J/kg or more at GREEN BAY WISCONSIN, July 31, 1999 (actually the evening of July 30 1999) I think the Plymouth sounding system uses a mixed layer, so I think the actual CAPE is over 7200 J/kg http://www.greatlakes.salsite.com/SevereStorms/high_CAPE/july_31_1999_00z_GRB_sounding.gif Link to comment Share on other sites More sharing options...
blackjack123 Posted June 1, 2011 Share Posted June 1, 2011 With insane parameters like that is just out of this world. I mean 9000-10000J/Kg, 1000m2/s2, LCL's 200m, 80-90kts, temperatures mid 80s, dews in the low to mid 70s, EHI's of 15, LI's of -12, followed by a powerful cold front or dryline, and addtional other insane parameters. I am afraid that some of our states would not be existing anymore. There would be multiple PDS tornado watches with all probabilities >95%. They would state numerous violent tornadoes, numerous wind gusts in excess of 180 mph, and numerous hail stones to the size of bowling balls/basketballs. You may also have flooding torential rains of one feet/hour. I would thin k something would be out of this world scary. Link to comment Share on other sites More sharing options...

Hoosier Posted May 25, 2013 Author Share Posted May 25, 2013 bump...here's another version of the Peoria sounding from the Plainfield tornado day. Sick, sick stuff. Link to comment Share on other sites More sharing options...
Stebo Posted May 25, 2013 Share Posted May 25, 2013 Like a 27c dew point, muggy would be an understatement. Link to comment Share on other sites More sharing options...
Hoosier Posted May 25, 2013 Author Share Posted May 25, 2013 Like a 27c dew point, muggy would be an understatement. I can tell you all about it...we specialize in 80 degree dews in the LAF. Plainfield is a good reminder that you still need to keep an eye out on days that may not look like much tornadic wise at first glance. Link to comment Share on other sites More sharing options...
BowMeHunter Posted May 25, 2013 Share Posted May 25, 2013 probably our inflatable mattress in the tent tomorrow night. We need a get together so you all can show my dumbness how to read a sounding. so calm, quiet and cool out there finishing packing the forgotten stuff. Does not seem and feel like memorial day weekend at all for some reason. I guess the last 3 yrs or so have skewed towards the wet fruit of the looms that this seems strange.

nwohweather Posted May 25, 2013 Share Posted May 25, 2013 As far as setups go I'd say Alabama on April 27th was the worst I've ever seen. 80-100 LLJ, CAPE up to 3000 j/kg and Helicity levels of 500-600 may never be seen again in our lifetimes. Let alone we saw 10 monster tornadoes including one that ran through the most populated parts of Alabama and one that IMO was the worst of all time in Phil Campbell Link to comment Share on other sites More sharing options...

Since we're bumping already...I know I've posted this in some other place, but 6/18/09: What a bust. Probably for the best, in the end. Link to comment Share on other sites More sharing options...
Ensō Posted May 25, 2013 Share Posted May 25, 2013 I saw this mentioned earlier but I'm surprised it wasn't posted, unless I missed it. Closest proximity sounding to Jarrell on 5/27/97 was Temple: And although it isn't quite as massively unstable as some of the others, 6/8/53 southeast of Flint: Link to comment Share on other sites More sharing options...
stormtrackertf Posted May 28, 2013 Share Posted May 28, 2013 I seem to remember some time in the late-90's/early 2000's an area in mid-Michigan had CAPE up around 7000 j/kg but the area was so tightly capped nothing significant ended up coming to fruition.

Ensō Posted May 28, 2013 Share Posted May 28, 2013 How about some other 6,000-7,000+ cases (some may have already been posted, I'll go check): 7/31/99, GRB: 7/13/95, MPX: 7/17/06, MPX: 8/3/06, BNA: Link to comment Share on other sites More sharing options...
Chinook Posted June 11, 2013 Share Posted June 11, 2013 Those ones from the previous post are actually posted on my web site (I should re-write that web page.) Anyway, I have a new nifty sounding for you. Last year, before the Super-derecho of 2012.. Davenport. Link to comment Share on other sites More sharing options...

MidwestChaser Posted June 11, 2013 Share Posted June 11, 2013 This is the closest I could get to the Chicago heat wave in 1995. I remember seeing a graphic on LOT's site some year's back of LI's near -25. Link to comment Share on other sites More sharing options...
Chinook Posted June 25, 2013 Share Posted June 25, 2013 I updated my high CAPE page, based on some of the things you guys posted here http://www.greatlakes.salsite.com/high_CAPE_1.html almost one year ago: 8000 J/kg analyzed by the RAP/SPC http://www.greatlakes.salsite.com/SevereStorms/high_CAPE/2012_06_29_00z_MUCAPE.png Link to comment Share on other sites More sharing options...
AlertIowa1234 Posted February 24, 2019 Share Posted February 24, 2019 Hate to reply to an old thread, but here is a sounding from Calcutta in April 2016. MLCAPE of 9753J/kg. Link to comment Share on other sites More sharing options...
