DISCUSSION...

Scattered thunderstorms will move across northeastern Oklahoma this

morning with a limited severe weather and heavy rain threat. 

Localized flooding is possible. After these thunderstorms exit the 

area to the east later this morning, hot and humid conditions will 

develop, with afternoon heat indices from 105 to 110 degrees for a

large portion of the area. Another round of thunderstorms is 

expected to develop late this afternoon and early this evening across

far northeastern Oklahoma and northwestern Arkansas. These 

thunderstorms will pose a risk of severe weather across much of the 

region as they move southeast across eastern Oklahoma and northwest 

Arkansas. The initial storms that develop will pose a tornado and 

large hail threat. Later in the evening, the thunderstorms are 

expected to evolve into a line, with the primary severe weather 

threat transitioning to damaging wind, with a lesser threat of large

hail.

EXTENDED DISCUSSION...

rainfall, will continue into next weekend. Updated forecasts should

be monitored through the week for the specifics involving these

threats.
