range over eastern Oklahoma and west central Arkansas. Excessive Heat
Warnings and Heat Advisories are in effect for much of the region
through 8 pm this evening, when these dangerously hot conditions will
improve.

Thunderstorms once again developed this afternoon in the very hot
and humid air mass that exists across the area. The strongest
thunderstorms will be capable of producing wind gusts of up to 50 to
60 mph, but any intense thunderstorm development is expected to be
short-lived due to the lack of wind shear to organize the activity.
Thunderstorms are expected to end this evening, as the atmosphere
stabilizes.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.

reach the upper 90s to just above 100 degrees. Dangerous heat index
values will continue each afternoon and additional heat advisories
will likely be needed. A frontal boundary will approach from the
north by Sunday and Monday, resulting in a chance of showers and
thunderstorms.
