Also... while not higher end potential, the threat (including tornadoes) looks pretty well squarely placed in Chicago metro. Always a little more concerning than usual when involving such populated areas.
This is really going to be a nowcast or near nowcast thing. Right now it seems like there may be just enough of a break and enough destabilization so that the setup isn't completely killed. Certainly conditional potential for a decent severe threat if things break favorably.
Am I correct that the humidex is more liberal than the heat index? Like for a given temp and dewpoint, the humidex value will be higher than it is on the heat index?
I looked it up. Seems like it's a fairly infrequent occurrence. The last time it happened at GRR was 2012. The high on March 14, 2012 was 80 with no 70s before that.
Spring has sucked, but it's a treat to have a day like this on a weekend. The wind is nice too because it takes the edge off of how warm it would feel with the body not being acclimated to temps like this yet.
