I have to laugh when I hear that phrase. Because there is no "normal" weather in Missouri.. We've had a hard freeze as late as May 10. I've seen snow in April (thank goodness I'm not seeing it this morning; our precipitation is still coming down in the form of rain).
Oh, there are a few things you can be sure of: It won't snow in June, July or August, for instance; or at least hasn't so far. I do recall some seventy-plus-degree days in the depths of winter. Yesterday I heard a weatherman on TV say that the record high for that date was 92... and that occurred just last year.
Some years we seem to have two or three tornado warnings a week; other times, you almost forget there's such a thing as a tornado, they're so rare.
I've seen years when it wouldn't stop raining (1993 is a good example), and times like last year where you couldn't beg, borrow or steal a few raindrops. We seem to get more of the latter, by the way.
So yeah, don't be surprised if you see me smile when you say something about "the crazy weather we're having this year."
It's Missouri. Deal with it.
