    Mesoscale Discussion 1089

    Areas affected...Eastern Iowa into far northeast Missouri and
    northwestern Illinois.

    Concerning...Tornado Watch 285...

    Valid 192218Z - 192315Z

    The severe weather threat for Tornado Watch 285 continues.

    SUMMARY...Several tornadoes have been confirmed from two supercells
    in east central Iowa. The tornado threat continues into the evening
    across the eastern half of tornado watch 285.

    DISCUSSION...Two supercells have generated numerous confirmed
    tornadoes across central and east central Iowa this evening. The
    tornado confirmed in Marshalltown, Iowa formed as the northern
    supercell interacted with the outflow boundary from the southern
    supercell. This supercell has now weakened significantly as it moved
    into a cooler airmass east of this outflow boundary. A tornado
    threat continues across the entire watch area, but the highest
    tornado threat is now associated with the supercell moving into
    Keokuk and Wapello counties where instability is maximized with
    MLCAPE around 2500 J/kg. Will be watching these storms for upscale
    growth over the next hour or two as some CAMS suggest these storms
    may congeal and pose a wind threat into northwest Illinois later
    this evening.
