early morning storms could become strong to marginally severe,
with hail and gusty winds. Later this morning, a complex located
over western Oklahoma will move into parts of eastern Oklahoma,
with a continued low-end severe weather threat. As this complex
moves over some of the same areas impacted by the early morning
storms, the threat of heavy rain and localized flash flooding will
develop across parts of eastern Oklahoma. Storms will gradually
shift east into western Arkansas through early this afternoon.

MONDAY AND TUESDAY...Thunderstorm Potential.
WEDNESDAY...Thunderstorm Potential...Dangerous Heat Potential.

EXTENDED DISCUSSION...
An active pattern will continue into the weekend with additional
rounds of thunderstorms possible through Tuesday. This will lead to
an increasing threat of heavy rainfall and possible flooding. Severe
weather will also be possible with any of the more organized
thunderstorm complexes in this pattern. The overall threat of
storms may begin to decrease by the middle of next week, with
hotter temperatures returning.
