Discussion...
mid clouds/scattered showers persist this afternoon in association
with trailing end of decaying mesoscale convective system that moved through MO overnight.
This has kept temperatures down 5 to 10 degrees from yesterday
across much of northeast Oklahoma and northwest Arkansas. Further
south, mostly sunny skies have allowed heat indices to climb
above 105 degrees in many areas. A few of the northern counties
currently in the heat advisory may be able to be canceled early
depending on latest cloud/precip trends.

The much anticipated cold front is currently located over northwest
Oklahoma, extending northeast into southeast Kansas/southern
Missouri. Breaks in the clouds ahead of the front have allowed
atmosphere to become moderately unstable across far northeast
Oklahoma with sbcapes around 3000 j/kg. As front slowly approaches
from the north tonight scattered showers/thunderstorms will be
likely across northeast Oklahoma and northwest Arkansas. A few
storms could be strong this evening with locally heavy rainfall
and gusty winds, but overall severe threat appears low at this time.
Thunderstorms chances will continue Friday as precip sags south with
the front into Friday night before finally shifting south of the
Red River by Saturday morning.

A cooler/drier airmass expected behind the front over the weekend
through the early to middle part of next week as upper trough
remains across the southeast Continental U.S.. this will provide a much
needed break from the heat with heat indices only in the upper
80s each afternoon.
