Update...
issued at 640 PM CDT Sat Aug 29 2015

No major changes planned for the overnight forecast. The sky will
remain a little hazy with smoke but with breezy southerly winds
visibility is not expected to be impacted tonight or Sunday.

Short term...(this evening through Monday night)
issued at 335 PM CDT Sat Aug 29 2015

Upper level ridging will be in place across the area tonight and
Sunday with toasty 850 mb temperatures in the +20s celsius. At the surface...a
tightening pressure gradient will bring an increase in southerly
winds on Sunday. With better mixing tomorrow and warmer temperatures
aloft...will be adding a handful of degrees to highs on Sunday
compared to what was seen on Saturday. Will have to keep an eye on
fire danger across central South Dakota Sunday afternoon as relative humidity values drop
into the 20s with gusty southerly winds. At this point it does not
appear to be low enough to warrant any headlines...but fire danger
will be elevated nonetheless.

Will then be watching the frontal boundary which models show moving
across the area on Monday. Still appears to be a limited potential
for precipitation with this front so will keep only slight chances in the
forecast for the time being.

Long term...(tuesday through saturday)
issued at 335 PM CDT Sat Aug 29 2015

There are a couple of frontal passages prognosticated for the out periods.
The one maintaining the highest probability of inducing
showers/thunderstorms looks to be sometime over the Labor Day
Holiday weekend. That is where the highest probability of precipitation are currently
forecast. Otherwise...the headline in the extended should
read..."unseasonably hot for the beginning of september".
