    The NWS Storm Prediction Center has issued a
    
    * Severe Thunderstorm Watch for portions of 
      central Minnesota
      southeastern North Dakota
      northeastern South Dakota
      northwestern Wisconsin
    
    * Effective this Friday afternoon and Saturday morning from 345
      PM until 100 AM CDT.
    
    * Primary threats include...
      Scattered damaging wind gusts to 70 mph likely
      Scattered large hail and isolated very large hail events to 2
        inches in diameter possible
      A tornado or two possible
    
    SUMMARY...Severe thunderstorms, including a couple of supercells,
    are expected to form across parts of the Red River Valley into west
    central Minnesota late this afternoon, before consolidating into an
    organizing cluster by early evening.  This cluster of storms is
    expected to then track east-southeastward across the remainder of
    central Minnesota into northwestern Wisconsin by late evening. 
    Initial storms may pose a risk for severe hail, with some potential
    for an isolated tornado or two, before strong wind gusts become the
    primary severe hazard later this evening.
    
    The severe thunderstorm watch area is approximately along and 65
    statute miles north and south of a line from 45 miles southwest of
    Detroit Lakes MN to 70 miles east northeast of Saint Cloud MN. For a
    complete depiction of the watch see the associated watch outline
    update (WOUS64 KWNS WOU0).
    
    PRECAUTIONARY/PREPAREDNESS ACTIONS...
    
    REMEMBER...A Severe Thunderstorm Watch means conditions are
    favorable for severe thunderstorms in and close to the watch area.
    Persons in these areas should be on the lookout for threatening
    weather conditions and listen for later statements and possible
    warnings. Severe thunderstorms can and occasionally do produce
    tornadoes.
    
    &&
    
    AVIATION...A few severe thunderstorms with hail surface and aloft to
    2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
    few cumulonimbi with maximum tops to 550. Mean storm motion vector
    28025.
