The northern third of Indiana, including Fort Wayne, has a slight risk of severe storms between 8 a.m. EDT tomorrow (July 12) and 8 a.m. EDT Sunday, according to a “Day 2 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 2:10 a.m.

People planning to attend outdoor events of the Fort Wayne Three Rivers Festival tomorrow should assure that they have a way to know about any weather warnings the NWS might issue tomorrow.  Possibilities include carrying a portable weather alert radio, installing a weather alert app on a smartphone and listening to a local radio station.

The timing of storms remains uncertain but the current outlook seems to indicate they are most likely Saturday night into early Sunday.

In addition to Fort Wayne, the slight risk area includes all of IMO SKYWARN quadrant two, except for the Ohio counties of Allen and Putnam and the southeastern half of Jay County, Indiana.

The SPC will issue an updated outlook for tomorrow by 1:30 p.m. EDT today. By 2 a.m. EDT tomorrow, an outlook for tomorrow will include probabilities of tornadoes, damaging thunderstorm winds and large hail.

The northern two thirds of Indiana and adjacent parts of Ohio, Lower Michigan and Illinois have a slight risk of severe weather between 8 a.m. EDT Saturday, July 12 and 8 a.m. EDT Sunday, according to the “Day 3 Convective Outlook” that the National Weather Service Storm Prediction Center (SPC) issued at 3:30 a.m. today.

This means that as Fort Wayne’s annual Three Rivers Festival gets started Saturday, damaging straight-line thunderstorm winds of 58 mph or greater and/or hail of one inch or more in diameter could threaten the festival’s mostly outdoor activities.

As you can see on the map above right, the slight risk area includes all of IMO SKYWARN quadrant two, except the Ohio counties of Putnam and Allen.

We won’t know much more about Saturday’s severe weather risk until the SPC issues a “Day 2 Convective Outlook” at around 2 a.m. tomorrow (Friday). I’ll write about that outlook sometime tomorrow morning, so check back on w9lw.farlowconsulting.com then.
