Additional rounds of thunderstorms are expected Thursday and Thursday night across Oklahoma and north Texas, with risks for both large hail and flash flooding. Strong winds may accompany any storms from east Texas northeast through the lower Great Lakes. Read More >
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.
Tornado or Funnel Cloud?
While we haven't received confirmation that a tornado touched down, it looks like the funnel cloud near North Manchester, IN was really close to being a tornado. These photos of the funnel were submitted to us through social media. This occurred around 4 pm EDT. There have been no reports of damage in this area as of 11:15 pm EDT 5/28. If you have any reports of damage, submit it to us using this form.

Later on in the evening around 7:30 PM EDT, a tornado warning was issued for southern Huntington County, IN. There were no reports of a tornado or even a funnel with this storm, however there was rotation observed on radar, as seen below. If you have any reports of damage, or if you saw a funnel cloud or tornado with this storm, submit it to us using the form.

Wind & Hail:
Severe storms led to reports of strong to severe wind gusts and pea to just over quarter-sized hail. The largest hail report was ping pong ball size (1.5") near Hicksville, Ohio.
Wind
While there were no pictures of wind damage submitted to us as of 11:15 PM EDT May 28, 2017, we did receive several reports of 40-60 mph wind gusts.

Flooding
Heavy rainfall from this event, combined with the excessive rain from the past month or so led to flooding. You can see in figures 3 and 4 that we are well above normal for May in many areas.

Environment
There are 3 ingredients needed to develop thunderstorms: Moisture, Instability, and Lift. To make those storms severe, wind shear is needed. On May 28th, 2017 a cold front moved through our forecast area during the afternoon and early evening hours. This provided the lift. We also had sufficient moisture transport ahead of the front, with precipitable water values up to around 1 inch or so. Instability and wind shear were also present, with about 1500 J/kg of surface based CAPE and 35-40 knots of shear.
Surface Weather Maps
A cold front is shown moving through the forecast area during the day/evening on May 28th, 2017 (Fig. 1-3). Additionally, at 300 MB we see a Jet streak, which led to additional upper level support for storms (Fig. 4-6). In the mid levels, an upper level trough was approaching the region.

Lift
Upper level divergence was present from the Jet at 300 mb, mid level support from the wave moving through the area (500mb).

Instability and Wind Shear
Instability was present when the front arrived, which made it easy for storms to develop. Wind Shear was also present, as seen in figure 6.

Moisture
Moisture was also present, as shown in the images below. Precipitable water values were around 1 inch.
