...UPDATE...

.DISCUSSION...
Mostly clear conditions were common across Eastern Oklahoma and
far Northwest Arkansas while scattered cirrus clouds lifted
northwest into West Central Arkansas this evening. To the
northwest...a frontal boundary stretched from Southwest Kansas
into Iowa. With Eastern Oklahoma and Northwest Arkansas south of
this boundary...southerly winds and warm/humid conditions
continued over the CWA.

Overnight tonight...some passing high clouds should continue to
move through the region with additional high clouds possible from
a MCS currently diving southward through Missouri. Temperatures
and dewpoints...like the past few night...are within a degree or
two from where they were 24-hrs ago. Thus...expect lows tonight
to get close to this mornings lows as not much change in the
airmass is forecast until the cold front arrives Sunday evening.
Lows in the mid to upper 70s will be possible for most
locations...with a few spots getting into the lower 70s. Current
forecast resembles this thinking and for the evening update have
only added in recent observations to account for latest hourly
trends.
