    POSTSCRIPT


    5/16: Kelvin-Helmholtz Instability just west of Smithville, MO.
    5/17: A thin line of thunderstorms developing above a weak dryline near Emporia, KS.
    5/20: A mature supercell near McAlester, OK.

    5/20: Some of the hail we encountered that afternoon... at times reaching 1.25 inches in diameter.
    5/20: John Griswold gazes over the dimpled hood of his truck. The hail was indeed big enough (golfball-size) to leave many obvious dents in both chase vehicles.
    5/20: Sunset-lit supercell just east of Kiowa, OK.

    5/20: One of inumerable lightning bolts we saw from Route 1 in OK on our way back to Ada from McAlester.
    5/25: A very large dust devil along Rt. 83 near Wellington, TX.
    5/26: Beautiful display of mammatus near Aspermont, TX. These were some of the largest ones any of us had ever seen.

    5/26: A well-defined wall cloud drops down from a strong supercell just southwest of Aspermont, TX.
    5/26: Classic sunset in the Texas panhandle.
    5/26: Another shot of a classic Texas sunset.

    5/27: Part of an incredible light show just northwest of Clinton, OK. The approaching storm was a line of strong cells, each one containing a visible mesocyclone.
