possible MVFR ceilings into SE OK and western AR early tomorrow

.PREV DISCUSSION... /Issued 156 PM CDT Tue Jun 30 2020/ 

DISCUSSION...
Near term item of interest continues to be the hotter temperatures
that are expected tomorrow and Thursday. Latest solutions
indicate mid level height rises tomorrow and Thursday, and with
surface dewpoints remaining in the mid 70s, heat indices will be
well within advisory criteria across most zones. That said, have
added the remaining zones across ERN OK to the heat advisory 
except for Adair county, and at this time will continue to leave 
the NW AR zones out. Expect less wind tomorrow as a surface 
boundary to the west draws closer to the area. Later in the day 
Thursday, and especially Friday scattered storm chances 
materialize as a back door front begins to move into the area. 
Slightly cooler air will move into the area behind the boundary, 
with modest decreases in surface dewpoints beginning Friday and 
continuing through the weekend. Storm chances through the weekend 
and into the early next week will remain low, and mainly confined 
to the higher terrain of SE OK and NW AR. Stayed close to the 
National Blend of Models for temperatures through the forecast 
period.
