Overview

A cold front moved through the forecast area on the afternoon of May 28th, 2017. Strong to severe storms brought funnel clouds, gusty winds, and large hail to the region. Heavy rain from the thunderstorms led to flooding problems, especially in areas where heavy rainfall occurred earlier this week. While a funnel cloud was visible in a storm near North Manchester, we have not received any reports of damage (as of 10:15 pm EDT). If you saw hail of 1" or greater diameter or have wind damage, please send your report to the National Weather service using this form.

Below is a GOES-16 visible loop from 1830-1914Z (230-314 pm EDT) of the deep cumulonimbus clouds that developed along the surface warm front over northeast Indiana and northwest Ohio. Line of bubbling cloud oriented northwest to southeast denoted the position of the actual surface warm frontal boundary. A mesoscale sector was in place over the area with imagery taken every minute.

*NOTE* The GOES-16 data posted on this page are preliminary, non-operational data and are undergoing testing. Users bear all responsibility for inspecting the data prior to use and for the manner in which the data are utilized.
