Hail??

So . . . I just checked the handy-dandy time/date in the lower right hand corner of my computer and it says that today is indeed Friday, April 18, 2008 (And, like Santa, I checked it TWICE!). I confirmed it with my day planner and the wall calendar that is conveniently not on my wall, but rather in my mess of work stuff at my computer. All three sources say that today is April, 18. If those sources are true (and maybe I should check with something more official . . . but . . . ) then why is it HAILING???!!

*Edit* It is now several hours later -the hail turned into snow and hasn't stopped since it started this afternoon (it is now 8PM). I'm glad I didn't have my heart set on a run today . . . it is COLD and dreary out there. On a cute note, though, my son wanted to know if the snow meant it was time for Christmas again. He wishes!
