   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 465
   NWS Storm Prediction Center Norman OK
   510 AM CDT Sun Jun 30 2019

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Eastern Minnesota
     Western Wisconsin
     Lake Superior

   * Effective this Sunday morning and afternoon from 510 AM until
     100 PM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 75
       mph possible
     Isolated large hail events to 1.5 inches in diameter possible

   SUMMARY...A complex of strong/isolated severe thunderstorms has
   turned south-southeastward along an eastward-moving instability
   gradient in northeastern Minnesota.  This poses an increased threat
   for damaging wind as these storms (and possible later development on
   their west side) encounter moist and unstable air through midday
   over the watch area.  See SPC mesoscale discussion 1311 for initial
   meteorological reasoning.

   The severe thunderstorm watch area is approximately along and 70
   statute miles east and west of a line from 70 miles northeast of
   Saint Cloud MN to 30 miles southwest of La Crosse WI. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU5).

   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
   1.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A
   few cumulonimbi with maximum tops to 550. Mean storm motion vector
   33035.
