    NewAlright, here's a start for stuff to put in the OP. If there is anything else or another question, I can add that.

    I have a bunch of links to observations, soundings, radar, satellite, models, etc on a site I put together to keep track of everything. I use SPC, COD, Pivotal Weather (PW), and Tropical Tidbits (TT) the most. COD has everything. http://wxsme.weebly.com/wx-links.html

    Radar stuff:
    Radar Fundamentals (NWS/Iowa State)
    How to read and interpret radar (Iowa State)
    NWS Jet Stream Doppler Radar
    Description of radar products (RadarScope) - near the bottom under "Radar Products"

    RadarScope (Apple and Android) - $9.99 one-time fee (9.99/year for lightning and a few other additional features)

    GR3 - 21 day trial or $80 one-time fee. Free NOAA/NWS radar feed, what I use at home. If you do happen to buy or get the trial, let me know and I can get you better color tables to use...the defaults suck. GR2Analyst uses Level 2 radar, essentially what is used in NWS offices. More expensive, data hog (if you chase with it). Iowa State has a free feed, otherwise you need pay 3rd party vendors for a reliable feed.

    Pykl3 (Android, not sure about Apple) - $9.99 one-time fee; I have this as well, it's nice but I prefer RadarScope for mobile. Pykl3 has more integrated GIS features and is more customizable than RadarScope

    Some app recommendations:
    aforementioned radar
    COD nexlab (only for iPhone)
    Weather Radio - essentially a mobile weather radio, can get NWS alerts based on your location
    SPC mobile
    NWS mobile forecast widget - the find your location feature doesn't seem to work; just plug in your zip

    Comet modules are used extensively in met classes and in the workplace:
    Skew-T - long module but covers everything you could ever want to know.
    Convection (some are quite technical, but if you're bored and want what a lot of met students get in the classroom (sans the equations), it's good - The first 3 are the most fundamental

    Decent algebra-based met textbook, focuses more on physical understanding, not the math: https://www.eoas.ubc.ca/books/Practical_Meteorology/

    The Weather Prediction website is a very thorough resource on most anything you would want to read about. Geared toward forecasting and has very little, if any math.

    US Tornadoes "Forecasting" stuff:
    Basics
    Boundaries and gradients
    What could go wrong

    SPC YouTube Tornado forecasting series, heavy emphasis on soundings and observations; highly recommend. There are 9 total videos

    TornadoTitans info on storm basics, skew-t/sounding, etc (haven't watched, but probably good enough to get a grasp)

    NWS Louisville Science Officer has tons of radar and storm dynamics stuff
    Hodographs - easy way to display winds throughout the atmosphere and shear
    Supercells

    A couple of papers on how tornadoes form and how the phrase "clashing airmasses" is highly misleading/physically incorrect way to describe how severe thunderstorms form.
    What we know and what we don't about tornado formation
    Clash of the airmasses

    To get a thunderstorm you need 3 things:
    1. Moisture (hard to get clouds and rain without moisture)
    2. Lift (hardest to diagnose; there was much better large-scale ascent last night (March 6) in Iowa and Minnesota than there was further south, large reason why those discrete supercells in AR and MO didn't get going until late)
    3. Instability (updraft strength/speed is directly proportional to instability --> higher instability = stronger updrafts

    Need a 4th ingredient to get severe:
    4. Wind shear (change in direction and speed with height; Generally, you'll see southerly-southeasterly winds at the surface that quickly veer (turn clockwise) west-southwesterly above the surface)

    This is key to storm organization; shear helps to organize storms and prevent precipitation from falling into the updraft, cutting it off. Shear also helps induce vorticity (spin) in the atmosphere that gives rise to mesocyclones (rotation of supercells). Supercells are amazing in that once they start to rotate, they self-sustain. The rotation induces mid-level low pressure --> "sucks" air up from below --> enhances the updraft and strength of the storm, augments the buoyant instability available to the storm. This is a reason why you can get supercells in an environment that some might consider to have marginal instability.

    In an ideal or classic case, supercells also can deviate to the right of the mean wind flow in their environment. What's the significance of this? This deviant motion enhances the low-level helicity --> enhances the shear and "spin" potential. Supercells are beasts that, by way of internal dynamics, can significantly enhance it's environment. Despite all of this, some research shows that only about 15% of supercells actually produce tornadoes.

    You can get tornadoes from non-supercell storms as well; also embedded within a line of storms. Often these squall line or QLCS storms have embedded supercellular circulations within them, rather than a discrete, classic supercell. Getting timely warnings out for QLCS tornadoes remains quite elusive as these things can form, produce damage, and dissipate within a few scans of radar or less (5-10 minutes).

    In high school, my parents were out of town and had a few buddies at my house having a few brews. Big ass storms started filing in, so we hopped in my Jeep and drove out to meet the storm coming in in Cheney (about 20 minutes from my hometown). We camped out there (had a few more beers) and watched the rain/hail, then followed it for a bit once the intense stuff went by. Ended up seeing a small tornado in a field following it back toward my house. Storm dissolved shortly after that and we headed back to my place.

    Lotta fun, pretty exciting but it was pretty dumb of us to head out there with no information other than an AM radio. Lol.

    i just got home, and was thinking about this thread...wind is blowin pretty good in Stillwater right now, and i heard all kinds of alerts on the radio about big storms in the state, but they're mostly further out west. we're only under a tornado watch for the next few hours here :curses:

    That's what I was thinking but if you look at the fronts right now, it's nuts. We're in a cold front, but there's a warm front rolling and a stationary front hovering around the state as well. Pretty crazy weather day overall.

    My senior year at Ole Miss I was on the phone with my dad who called to say there were tornadoes in my area and wanted to see if everything was ok. I told him it was getting dark outside (it was like 3 in the afternoon) but I didn't think there were any tornadoes. Just as I said that my roommate yelled to come outside. Walked outside and saw a tornado about 2 miles away going away from our house. It was awesome and definitely made the sound of a train like they say they make. I'd love to do a tornado chase after that experience, they're incredible.

    /cool story hansel.

    I was in a tornado when I was in HS. Pretty crazy shit. My dad had to take out six inches of soil from our yard to make sure he got all the glass that had been buried into it by the wind. All my clothes had glass and fiberglass in them. Tornadoes haven't been nearly as cool since that shit.
