   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 89
   NWS Storm Prediction Center Norman OK
   305 PM CDT Wed Apr 8 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southeast Iowa
     Western and Central Illinois
     Eastern Missouri

   * Effective this Wednesday afternoon and evening from 305 PM
     until 900 PM CDT.

   * Primary threats include...
     Scattered damaging winds likely with isolated significant gusts
       to 80 mph possible
     Scattered large hail likely with isolated very large hail events
       to 2.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Storms will quickly increase and intensify near/ahead of a
   southeast-accelerating cold front. The environment is favorable for
   initial supercells capable of large hail. Damaging winds will also
   become an increasing concern by early evening as storms tend to
   merge and organize into a fast-moving line particularly across
   central/southeast Illinois.

   The severe thunderstorm watch area is approximately along and 105
   statute miles east and west of a line from 55 miles north of
   Bloomington IL to 45 miles south southwest of Saint Louis MO. 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 87...WW 88...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 70 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   29040.
