    Severe Thunderstorm Watch Number 359
    NWS Storm Prediction Center Norman OK
    400 PM CDT Sat Jul 11 2020
    
    The NWS Storm Prediction Center has issued a
    
    * Severe Thunderstorm Watch for portions of 
      Eastern Iowa
      Northern Illinois
      Far Northeast Missouri
    
    * Effective this Saturday afternoon from 400 PM until Midnight
      CDT.
    
    * Primary threats include...
      Scattered damaging winds likely with isolated significant gusts
        to 75 mph possible
      Scattered large hail and isolated very large hail events to 2
        inches in diameter possible
      A tornado or two possible
    
    SUMMARY...Strong to severe thunderstorms may persist/redevelop along
    a northwest/southeast-oriented boundary across the region, while
    other storms are expected to further organize across east-central
    Iowa and move southeastward into the region. Large hail is possible
    but there will be an increasing concern for damaging winds across
    the region by evening. A tornado cannot be ruled out, particularly
    along the aforementioned boundary.
    
    The severe thunderstorm watch area is approximately along and 65
    statute miles north and south of a line from 25 miles west southwest
    of Cedar Rapids IA to 15 miles north northeast of Danville IL. For a
    complete depiction of the watch see the associated watch outline
    update (WOUS64 KWNS WOU9).
    
    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.
    
    &&
    
    OTHER WATCH INFORMATION...CONTINUE...WW 356...WW 357...WW 358...
    
    AVIATION...A few severe thunderstorms with hail surface and aloft to
    2 inches. Extreme turbulence and surface wind gusts to 65 knots. A
    few cumulonimbi with maximum tops to 550. Mean storm motion vector
    32030.
