301 PM CDT THU AUG 25 2016

.SHORT TERM...(This evening through Friday)
Issued at 301 PM CDT Thu Aug 25 2016

Gusty northwest winds across the area will quickly subside this
evening as heating dies away. Expecting good radiational cooling
resulting in lows in the upper 40s to lower 50s across the region.

Short wave will approach front the west on Friday resulting in
increasing clouds.  With not a lot of low level moisture available,
instability will be quite limited.  Have raised pops in the Missouri
River Valley after 21z as dynamics really start to increase across
the area. Highs will generally be cool in the 70s.

.LONG TERM...(Friday night through Thursday)
Issued at 301 PM CDT Thu Aug 25 2016

Energy currently diving through the southern and central Rockies
will spread onto the plains and wrap northeast Friday night into
Saturday morning. Due to fairly weak instability severe weather is
not expected with this wave, but there will be a good chance for a
more widespread and rain and isolated thunderstorm threat. Will ramp
up pops as the lift and mid level moisture increase Friday evening
then decrease pretty quickly on Saturday morning as the deeper
moisture lifts northeast. Will maintain some small chance for
showers and isolated thunderstorms as the main wave scrapes through
northeast South Dakota into Minnesota. Saturday will be mild as
clouds clear from the southwest through the day. Will have the
coolest readings in southwest Minnesota and northwest Iowa in the
mid 70s while lower 80s will be possible in south central SD. Sunday
will be much warmer as southerly flow develops. Expect highs in the
lower 80s in northwest Iowa to the lower 90s in central SD.

In the outer periods (Monday through Thursday), Overall this time
frame looks fairly quiet as flat upper level ridging becomes a
little sharper. Only very small chances for thunderstorms so
expecting mostly dry conditions. However with the upper level ridge
in place temperatures should run about 5 to 10 degrees above normal
through the entire time frame. Overall highs in the 80s with lows in
the 60s. A very nice late summer pattern if you are not in need of


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1214 PM CDT Thu Aug 25 2016

VFR conditions expected through the period. Surface high pressure
will shift east through Friday morning with increasing
southeasterly flow on Friday. Could see some showers/thunderstorms
approach the Missori river valley after 18z on Friday.
