.DISCUSSION...
Convection has begun over west Texas, and scattered or isolated
storms are expected to affect far western Oklahoma as well by
mid-evening. Large CAPE values suggest the possibility of severe
storms...again. Increasing mid-level temperatures should help
shut down convection for the next day or two.

A large upper-level wave is still forecast to edge slowly east
this weekend and into next week. This will bring rain chances to
the far western parts of Oklahoma this weekend, then spread across
the remainder of our forecast area late in the weekend and early
next week. Its slow movement makes it challenging to pin down
the geographical extent of the expected rain at any given time.

In addition to the increasing chances for rain, the change in the
upper-air pattern will also bring cooler weather to the southern
Plains. Temperatures will drop to near the seasonal average around
Sunday, then below average for early next week.
