Even Stevens
So we finally have drought on the run across southwestern Oklahoma, thanks to the ginormous rains of the last two months, when northeastern Oklahoma decides to become the current problem child.

While the amount of drought in the state remained virtually unchanged (9.11% last week, 8.94% this week), the decrease in the SW was replaced by an increase in the NE. A near even exchange.

Now I think we're still set up in a pretty nice situation for drought removal over the next week, but NOT so pretty if you're worried about flooding, especially over western Oklahoma. The scenario remains the same as far as I can ascertain... we have that large upper-level trough dominating the western half of the country and the eastern half under a ridge of high pressure. With us stuck in between, we should continue to see abundant moisture flow on southerly winds from the Gulf of Mexico. As small storm systems rotate through the larger flow pattern, we'll see rain chances now and again. Then the biggie moves through early next week and we get inundated.
Heck, we have a cold front sagging into northern Oklahoma right now, causing showers and storms AND some decent rains very close to our problem drought area in the NE Oklahoma.

There's even a flood warning for Kay and Noble counties.

So if you look at the CPC 6-10 day outlooks, you can definitely see the influence of that large trough and moisture from the Gulf.

I really do think we'll see widespread relief across all the remaining drought areas over the next week or so. The 7-day rain forecast certainly looks favorable for that!
