The spin threat is higher than a severe t-storm threat, as weird as that sounds.
You don't want to be just east of the rotation ... which is exactly where Harrisburg is.
If anyone is curious what the exact dead center of Pennsylvania is, I had to discover it for a map I'm creating.
It's 200 Windy Butte Lane in Spring Mills, Centre County.
I think even I'm too east for anything from Fred. I'll prob have to get rain from the afternoon line, and that's hit/miss as always (though likely a hit as it looks solid)
Good news - got a roofer over here to discover my leak is from a hole in a shingle (probaby from a falling tree branch). He's coming back at 7 a.m. tomorrow to fix, which should beat any real rain as it won't start until the afternoon most likely.
