    Areas affected...Western/central Wisconsin

    Concerning...Severe Thunderstorm Watch 299...

    Valid 101118Z - 101245Z

    The severe weather threat for Severe Thunderstorm Watch 299
    continues.

    SUMMARY...An isolated large hail and damaging wind threat will
    accompany a small cluster of storms moving into central Wisconsin
    this morning.

    DISCUSSION...Warm advection over the outflow from earlier morning
    convection has promoted a few stronger/deeper thunderstorms within
    the northern Coulee region. This activity is on the fringe of the
    steeper mid-level lapse rates and effective shear (perhaps around
    25-30 kt). It is not clear how far east this complex of storms will
    progress as buoyancy and shear decrease with eastward extent and the
    low-level jet will weaken. The current thinking is that isolated
    large hail and perhaps strong/damaging winds are possible over the
    next 1-2 hours. An additional watch is not currently expected this
    morning.
