   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 348
   NWS Storm Prediction Center Norman OK
   1105 AM CDT Thu Jul 9 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Central and Eastern Iowa
     Northwest Illinois
     Southeast Minnesota
     Southwest Wisconsin

   * Effective this Thursday morning and evening from 1105 AM until
     700 PM CDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Scattered large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...A remnant MCV (mesoscale convective vortex) will continue
   to contribute to severe thunderstorm development initially across
   northern Iowa into southeast Minnesota. Over time, additional storms
   should develop across broader portions of eastern Iowa. Damaging
   winds should be the primary hazard, but some severe hail may occur,
   and a tornado cannot be entirely ruled out.

   The severe thunderstorm watch area is approximately along and 110
   statute miles north and south of a line from 50 miles west southwest
   of Waterloo IA to 25 miles east southeast of Dubuque IA. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU8).

   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 60 knots. A
   few cumulonimbi with maximum tops to 600. Mean storm motion vector
   25025.
