I didn't want to ruin your day. Mine was ruined when my attempt to eat 13 Hostess Honeybuns in under 5 minutes was foiled by my alarm going off...it was actually a dream but my pillow sure tasted good.
So we've done this several times since our drought-that-used-to-be-flash-drought- but-is-now-just-drought began back on June 11. Back in July we had our first "driest last 30 days in 100 years" going on in addition to an explosion of summer heat, the hottest summer we've seen in these parts since 2011, in fact. So that was the beginning of the flash drought. Then we get to September and after some decent rains across various regions of Oklahoma, we start yet another month-long dearth of precip. The tragedy here is that we are missing out on what is considered our secondary rainy season, that period when the jet stream dips down our way and we get good return flow from the Gulf. For quite a few locations, September is the 3rd or 4th wettest month of the year behind May, June, and sometimes April or October--the eastern half of the state usually...the fall is a bit drier across western OK.
At any rate, we're missing out! In fact, since that flash drought began back on June 11, that's also the driest such period in the last 100 years (or the driest last 115 days in the last 100 years).

There is some wet (and cooler) weather on the way over the weekend into early next week. I still don't see any drought-busting rains. I wouldn't even call these drought-delaying rains.

But it's a start.
