-central Arkansas this morning. Additional thunderstorms will be possible
late Tonight across portions of northeast Oklahoma as a weakening thunderstorm
complex approaches the area.

High relative humidity values in place will combine with warm afternoon
temperatures, resulting in heat index values between 98 and 103 degrees
this Afternoon across southeast Oklahoma and west-central Arkansas.

EXTENDED DISCUSSION...
Better chances for thunderstorms will come Friday evening
into the overnight hours as a storm complex moves south into the region.
Additional moderate to heavy rainfall may raise flood concerns
over locations that have seen several rounds of heavy rainfall
this week. The wet pattern breaks by the weekend as some upper
level ridging takes place in the wake of the departing storm
complex. Heading into early next week...thunderstorm chances
overall will remain low...with any isolated storms remaining
confined to the late afternoon or early evening hours. Storm
coverage may increase towards the middle of next week as a frontal
boundary approaches the region.
