Some marginally severe thunderstorms are popping up in north-central and northeastern Indiana this afternoon. The storms have dropped hail measuring up to .75 inches in diameter. The threat is too isolated and marginal to justify a severe thunderstorm watch, according to a mesoscale discussion from the National Weather Service (NWS) Storm Prediction Center. But the northern Indiana NWS office has issued some severe thunderstorm warnings and more are possible.

Extreme southern Indiana — along the banks of the Ohio River — has a slight risk of severe weather between 9 a.m. EDT today and 8 a.m. EDT tomorrow, according to the updated “Day 1 Convective Outlook” that the National Weather Service Storm Prediction Center issued at 8:28 a.m. EDT. Thunderstorms are forecast for the remainder of Indiana but forecasters expect none of those to be severe.
In the parts of Indiana that fall in the slight risk area, damaging thunderstorm winds of 58 mph or stronger and large hail of one inch or more in diameter are the primary threats.
Most of the western half if Indiana, most of Illinois and parts of many other states to the south have a slight risk of severe storms today and/or tonight, according to the “Day 1 Convective Outlook” that the National Weather Service Storm Prediction Center issued at 8:49 a.m. EDT.
The greatest threat in the slight risk area is damaging thunderstorm winds of 58 mph or greater.

The northern Indiana NWS office (@NWSIWX) has been doing a great job with Twitter for some time.
I encourage SKYWARN storm spotters who have not yet embraced this medium — including my fellow ham radio operators — to do so, as I did recently.
One advantage of Twitter is the ability to easily include photographs for visual verification of spotter reports.
I welcome your comments, using the link under the title of this post.
Areas along the western edge of Indiana have a slight risk of severe weather between 8 a.m. EDT tomorrow and 8 a.m. EDT Friday, according the “Day 2 Convective Outlook” that the National Weather Service Storm Prediction Center (SPC) issued at 1:16 p.m. EDT. The slight risk area also includes most of Illinois and parts of several other nearby states to the west and south.
The greatest threat in the slight risk area is damaging straight-line thunderstorms winds of 58 mph or stronger, from a squall line that forecasters expect will develop tomorrow afternoon.
The SPC will update its outlook for tomorrow when it issues the first of several “Day 1 Convective Outlooks” at around 1 a.m.
There is a slight risk of severe thunderstorms in parts of Indiana, Illinois, Michigan and Wisconsin between 8 a.m. EDT tomorrow and 8 a.m. EDT Sunday, according to the “Day 2 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 2:03 a.m.
The slight risk area covers the northwestern half of the county warning area of the Northern Indiana NWS office. Except for a bit of northwestern Whitley County, IMO SKYWARN quadrant two lies outside the slight risk area.
That means that while thunderstorms are forecast in the Fort Wayne area for the popular Johnny Appleseed Festival, meteorologists do not at this time expect severe storms (i.e. storms with winds at or above 58 mph or hail of one inch diameter or larger) there.
The SPC will update its outlook for tomorrow by 1:30 p.m. EDT today.
National Weather Service meteorologists surveyed damage from Wednesday’s storm in Van Wert County yesterday. They found no evidence of a tornado touchdown but did find thunderstorm wind damage. Their preliminary report appears below.

A suspected tornado struck eastern Van Wert County yesterday afternoon. A storm cell moved through eastern Van Wert County at 5:10 p.m. EST just west of Delphos and caused damage over a 1.5-mile-long area, according to Van Wert County Emergency Management Director Rick McCoy.
McCoy said that based on witness reports and observed damage, it appeared that a tornado moved through the area but he was waiting on official confirmation from the National Weather Service (NWS). A survey team from the northern Indiana NWS office is scheduled to assess the site this afternoon.
McCoy’s own survey of the area and interviews with residents provided the following information:
The possible tornado initially touched down in a corn field east of Brickner Road, one tenth of a mile south of Lincoln Highway, which is 1.25 miles west of Delphos. The damage path in the corn field was 25 yards wide, where some corn stalks had been flattened and others ripped out of the ground and carried across Brickner Road.
The storm then crossed Brickner Road, moving to the northeast through a bean field.
It then struck the Craig Beining property at 10671 Brickner Road, ripping numerous shingles off a barn roof and tearing a barn door off of north side of barn.
The storm then crossed Lincoln Highway and struck the Joe Wittler property at 23121 Lincoln Highway, where it uprooted a tree and tore numerous limbs out of several trees. It then ripped a barn door off the east side of a Morton building, ripped off a door on the north side of a larger barn and tore numerous slate shingles from the barn’s roof.
Wittler told McCoy he saw the storm approaching but the possible tornado was wrapped in rain, so all he could see was all the shingles from the neighbor’s barn swirling around in the rain as it came at him. He said he heard a loud “whoosh” and that it hit before the family could even get to the basement.
The storm path continued northeastward, cutting through two bean fields and then crossed Pohlman Road. It then cut through another bean field and then came to the Gordon Moenter property, located at 9874 Shenk Road
There, McCoy found a damage path in a field that was 25 yards wide. The storm split a large tree and tore the roof off of a barn. McCoy found the roof in splintered pieces across the road and in a bean field. The storm also tore the barn door off the east side of another barn.
The storm path then continued northeastward through two more bean fields, where the damage path ended before it reached the intersection of U.S. 30 and the Ohio State Route 66.
The total damage path was 1.5 miles long. No injuries or damage to homes were reported.
McCoy estimated the tornado as high end EF-0 damage.
The vigorous storm system that moved through the area yesterday had been forecast several days in advance with the possibility of isolated tornadoes.
