DISCUSSION...
Thinning clouds this morning will allow for additional surface
heating this afternoon with moderately unstable conditions. As
upper disturbance approaches from the west, additional scattered
thunderstorms will be likely across portions of eastern Oklahoma.
PWAT will remain around 2 inches with the potential for locally
heavy rainfall in the stronger storms. Increased pops across
aforementioned area this afternoon into this evening. Precipitation
chances will likely need to be increased further as location of
the heavier thunderstorm bands become more certain. Update out
shortly.
