.DISCUSSION...
Hot and humid conditions will be the rule for much of the forecast
period, with some minor heat relief possible by Friday or
Saturday. Maximum heat index values may touch the magic 105
threshold in a few spots both today and Sunday, with more
widespread 105+ heat index values becoming more likely during the
Monday through Wednesday timeframe. Will hold off on a heat
advisory at this time, and let the day shift monitor temperature
and dew point trends today. One big difference from this round of
heat as compared to the last one is that southerly winds will be
quite breezy this time around, thus WBGT values will remain lower
than they were then, keeping the heat stress lower.

An upper level system passing to our north will bring a chance of
showers and thunderstorms late tonight and Sunday, with the 
highest chances in northeast Oklahoma and northwest Arkansas. An
isolated severe storm or two will be possible Sunday. Shower and
storm chances may linger through at least Sunday night across
parts of far northeast Oklahoma and far northwest Arkansas as
well.

Shower and thunderstorm chances will return Wednesday through the
end of the week as a frontal boundary approaches from the north.
This front will eventually push into and through the area, but it
may take it until Friday or Friday night to have any real effect
on temperatures. 

Stayed close to the National Blend of Models forecast.
