   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 45
   NWS Storm Prediction Center Norman OK
   735 PM EST Tue Feb 28 2017

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Northern Indiana
     Southern Lower Michigan
     Northwestern Ohio
     Lake Erie
     Lake Michigan

   * Effective this Tuesday night and Wednesday morning from 735 PM
     until 400 AM EST.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible
     Isolated damaging wind gusts to 70 mph possible
     A tornado or two possible

   SUMMARY...Multiple rounds of thunderstorms are expected to spread
   across this region north of a warm front, offering the potential for
   large hail and isolated strong-severe gusts.  A tornado cannot be
   ruled out later tonight over parts of northern Indiana as well, but
   that threat is more conditional and uncertain at this time.  See SPC
   mesoscale discussion 222 for initial meteorological reasoning.

   The severe thunderstorm watch area is approximately along and 55
   statute miles north and south of a line from 30 miles southwest of
   Benton Harbor MI to 15 miles east southeast of Detroit MI. 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
   2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 450. Mean storm motion vector
   26035.
