First PDS Severe Watch
Severe Risks: SPC Outlooks
I knew the potential for Severe Storms was great, however, I also came to the realization that the best chance of severe weather was in the 8600 CAPE area in Central and North Central Illinois. Having worked all day Monday and having to work Tuesday, I decided that was pretty much a chase that wouldn’t happen.
After work I drove to Battle Creek and ended up sitting around for a couple hours. I filled up and washed & Rain-X’ed my windows.
A Derecho formed in North Central IL and was heading towards the Chicago Area. I decided to start dropping southwest towards the South Bend, IN area to intercept. The SPC then issued a Particularly Dangerous Situation (PDS) Severe Thunderstorm Watch for Northwest Indiana. It was the first time I had really seen a PDS Severe watch in our area – and was the first time I had ever been IN one.
I headed down US-131 to US-20 south of Elkhart and South Bend. I took US-31 South to Lakeville, IN. I wanted to make it all the way to Plymouth, IN but knew I would never make it so I found an open spot where chances of debris hitting me would be significantly less. While I was sitting there waiting on the storm to hit me, The Weather Channel called and asked if I could do a phoner with Jim Cantore.
I ended up driving east on US-6 and not finding any damage so I drove west to where all the reports of damage was coming in from La Porte and Michigan City. I ended up finding nothing and returned home up 94 to 69 to Lansing. I pulled in around 3 am. I was at work again at 745 am the next morning. Needless to say, Tuesday I was tired.
