Thunderstorms, including severe storms, could develop in northern Indiana by 5 p.m. EDT, according to a “mesoscale discussion” that the National Weather Service Storm Prediction Center issued at 2:58 p.m. EDT. The discussion indicated a 40 percent chance that a watch will be issued.

Nearly all of the northern Indiana National Weather Service (NWS) county warning area (CWA) now has a slight risk of severe weather between 12:30 p.m. today and 8 a.m. tomorrow, according to an updated “Day 1 Convective Outlook” the NWS Storm Prediction Center issued at 12:27 p.m. EDT. The following counties are the only ones in the CWA that are entirely out of the slight risk area: Grant, Blackford and Jay. An earlier version of the outlook excluded more counties on the south side of the CWA.
Damaging straight-line winds and hail remain the primary threats, but a short-lived tornado is also possible.
The severe storms are most likely this evening through the overnight hours, according to a “Hazardous Weather Outlook” the northern Indiana NWS office issued at 1:24 p.m. EDT. That outlook also indicates that SKYWARN storm spotter activation might be needed tonight.
Our next update of the severe weather picture for this evening and tonight comes when the SPC issues an updated day one outlook by 4 p.m. EDT.

Extreme northern Indiana and nearby areas have a slight risk of severe weather between 9 a.m. today and 8 a.m. tomorrow, according to the “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 8:44 a.m. today.
The slight risk area covers essentially the northern three quarters of the county warning area (CWA) of the northern Indiana NWS office, or all of IMO SKYWARN quadrants one and four and the northern parts of quadrants two and three. Quadrant two counties included in the slight risk area today are Whitley, Allen (Ind.), Paulding and Putnam.
The primary threat in the slight risk area is damaging straight-line wind of 58 mph or more. Storms could affect the area as early as late this morning but they’re more likely from this afternoon into this evening.
The SPC will update its day one outlook by 12:30 p.m. and 4 p.m. today.

The entire northern Indiana CWA has a slight risk of severe weather between 8 a.m. tomorrow and 8 a.m. Thursday, according to the “Day 2 Convective Outlook” that the SPC issued at 1:33 a.m. today. Tomorrow’s slight risk area covers most of the northern half of Indiana and large parts of nearby states.
Forecasters expect widespread storms by late afternoon tomorrow from northern Illinois and Indiana into Pennsylvania and southern New York. The primary threat will be damaging straight-line winds, but the atmosphere will be also unstable enough for large hail.
The SPC will update its day two outlook by 1:30 p.m. EDT today. The subsequent update comes as tomorrow’s first day one outlook by 2 a.m. EDT.
If you’ll be in the slight risk areas today or tomorrow, plan to have a way to learn of any watches or warnings the NWS might issue, especially if you’ll be involved in outdoor activities, such as sporting events. Also have a plan for seeking safe shelter.
If you’re a SKYWARN storm spotter, be prepared for activation. Check your communications equipment, review reporting criteria, etc.

The northern fourth of Indiana and parts of several nearby states have a slight risk of severe weather between 8 a.m. EDT Wednesday, June 18 and 8 a.m. EDT Thursday, June 19, according to the “Day 3 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 1:24 a.m. EDT today.
The main threats will be damaging straight-line winds of 50 knots (58 mph) or higher and marginally severe hail of one inch in diameter.
As you can see on the map above, the slight risk area includes most of the Indiana, Michigan and Ohio counties that are in the county warning area (CWA) of the northern Indiana NWS office. The only CWA counties completely outside the slight risk area are Grant, Blackford and Jay.
If you’re planning any outdoor activities in the slight risk area Wednesday, be sure you have some way of knowing about any storm watches or warnings that the NWS might issue. Also be sure you have identified safe shelter nearby.
If you’re a SKYWARN storm spotter, fuel up your vehicle and charge up and check your communications equipment, so you’ll be ready for activation on Wednesday.
Risk areas often change as the outlook period nears. The SPC will issue its next outlook for the period by 2 a.m. tomorrow (the first of two “Day 2 Convective Outlooks” it will issue tomorrow). So check back tomorrow to see how the outlook might have changed.
If it seems that we haven’t had the usual amount of severe weather this spring, that’s because we haven’t! In fact, the low amount of severe weather this year in northeastern Indiana, southern Lower Michigan and northwestern Ohio is nudging records, as you can see in the tweet below from the local National Weather Service office:
YTD, we’ve only issued 22 severe thunderstorm warnings. That’s a new record low since office opened in 1998! pic.twitter.com/uYIMU7WUZK

More showers expected today. Could see a lull in activity this morning-early afternoon before another round moves across the area.

A few rumbles of thunder will not be out of the question this afternoon but severe weather is not expected.

In mid-May, NWS Warning Coordination Meteorologist Michael Lewis sent an email message to spotters with the graphic above, to remind them of the best ways to report various severe weather phenomena. He also asked spotters to review the following Web pages:

Steve Haxby, N9MEL is now an official net control station operator for the IMO SKYWARN quadrant two net on the ACARTS 146.88 MHz repeater. Steve has maintained his official NWS spotter training and is well acquainted with public safety work, having retired from the Allen County Police Department. If you hear him take a shift, please congratulate him and welcome him to the position. As a reminder, should the 146.88 MHz demonstrate performance issues during SKYWARN operations, SKYWARN will move to the FWRC 146.76 MHz repeater. Also, keep in mind that our net in Fort Wayne simultaneously serves as an Allen County (Ind.) net and a quadrant net, serving 11 counties. See a map of IMO SKYWARN quadrants.

Several local hams configured dozens of NOAA weather radios for members of the general public at two Fort Wayne events in May. The first was Monday afternoon and evening, May 12, at the Walgreen’s store on Coldwater Road at Dupont Road. The second was Saturday afternoon, May 17 at the Kroger Marketplace on West Jefferson Boulevard.
The following people did an excellent job assisting the public and representing amateur radio: Tom Baker, N9TB; Al Burke, WB9SSE; Jim Boyer, KB9IH; Steve Haxby, N9MEL; Jim Moehring, KB9WWM; Howard Pletcher, N9ADS; Tom Rupp, KU8T; and Charles Ward, KC9MUT. Representatives of the Allen County Office of Homeland Security and WANE TV also participated. Photos of both events are available on the Fort Wayne Radio Club website.
When correctly programmed, these radios remain silent until the National Weather Service issues a watch or warning for the user’s specific county. This eliminates the annoyance of being alerted to far-away storms and therefore reduces the temptation to shut off the radio, rendering it useless when a storm actually threatens the user.
If you don’t have such a radio, I strongly recommend obtaining one. Post a comment below if you have any questions about NOAA Weather Radios, etc.
