Wow! What if you threw a Biblical disaster party and Moses RSVP'd for tornadoes and flaming hail and Noah showed up instead? Oh, we had our tornadoes. Maybe not the outbreak of long-tracked violent behemoths, but an outbreak nonetheless. I'm gonna hazard a guess (get it?) and say we had 15-20 tornadoes? I think if we could have said Sunday we're gonna see 15-20 tornadoes Monday starting in the early afternoon, then the preemptive closings were proper. We just never saw storms go up in the warm sector to the south and east. VERY thankful for that. At any rate, we can do the postmortem on this severe event later, but right now the rains -- for some historic rains -- are still plaguing us (but so is the severe weather in eastern Oklahoma).

And it has left an already waterlogged state wondering where it's all going to go. We're basically one great big flood warning right now. And the flash floods will all create more areal floods.

Just one instance, Bird Creek near Avant has topped it's historic crest record (back in March 1974) by more than 3.5 feet!

I thought, "WOW, I wonder if we can break the all-time May record for rainfall?" I had forgotten just how bad May 2015 was, however. While we're already up to our 11th wettest May on record with a statewide average of 7.51 inches, May 2015 had that whopping 14.44 inches to set the record for the wettest month of any month, not just May. We have 10 more days to go, but I don't see up doubling what we've already had.
Here are the stats through today, compared to similar periods back to 1921.

Storm chances remain for the rest of the week. Thursday is the biggie again, this time NW OK is in the crosshairs. Sorry Moses and Noah, you ain't invited.
