DISCUSSION...
Thunderstorms developed this afternoon near a remnant boundary
across southeastern Kansas and north central Arkansas. Some of this
developed into northeastern Oklahoma and northwestern Arkansas this
evening, although thus far it has been very isolated in the TSA CWA.
Maintained low pop across northeastern Oklahoma and northwestern
Arkansas through much of the night, which is supported by high-
resolution, rapid update models. Most areas unaffected tonight,
however.

Mainly diurnal convection expected again on Sunday as air mass warms
into the 90s with dewpoints well into the 70s. Heat Advisory may need
to be tweaked some based mainly on dewpoint temperature forecast,
which will impact forecasted heat index values. Thanks to our August
rains, much more humid than what we normally experience in late
August.
