Special Weather Statement issued April 13 at 12:06AM EDT by NWS Northern Indiana

Gusty south winds could briefly gust as high as 50 mph for a short time during the early morning hours through around 3 AM EDT. A band of showers moving across northwest Indiana and southwest Lower Michigan will likely aid in producing some stronger wind gusts of 40 to 50 mph. If travelling, be prepared for brief periods of these stronger wind gusts, particularly for high profile vehicles.
