The latest U.S. Drought Monitor map (from last Thursday) was definitely ugly, and given that the new on on Thursday only considers what happened up through Tuesday morning (a whole lot of nothing!), you can expect it to look worse. But it will *probably* be raining heavily at that time...especially across western Oklahoma.

For the western and central portions of the state, that should be the bulk of the precip. Check out the rainfall total map just released by WPC for now through Friday.

ZOUNDS!! 5 inches across western OK and NW Texas? What is this, May? There will be a definite flooding threat with that type of rainfall.
After that, the focus shifts further to the east where a frontal boundary should stall out and interact with that Gulf moisture, allowing for possible drought ease-ification later into the weekend.

The point, which I rarely approach, is that it's going to rain after a long, LONG hiatus for significant portions of the state. So be prepared for heavy rainfall, and also be prepared to ignore the new Drought Monitor map that comes out on Thursday.
Just in case.
