Area Forecast Discussion
National Weather Service Sioux Falls SD
627 PM CDT TUE SEP 27 2016

.SHORT TERM...(This evening through Wednesday)
Issued at 258 PM CDT Tue Sep 27 2016

Gusty winds should quickly subside this evening as mixing dies
away. Large area of stratus to the north is expected to work down
across southwest Minnesota into northwest Iowa tonight into
wednesday morning.  Have not changed temps much from blend with low
deviation in guidance.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 258 PM CDT Tue Sep 27 2016

Surface high pressure will be in control Thursday and Friday which
will allow for lighter winds and mostly clear skies. The winds will
be a little stronger in central South Dakota with the ridge of high
pressure mainly along and east of Interstate 29. Highs will be from
the upper 60s to lower 70s both days with lows in the 40s.

In the outer periods (Saturday through Tuesday), ridging aloft will
gradually shift east of the area as a trough of low pressure moves
from the west coast and Rockies onto the plains. The dry and
pleasant weather will continue this weekend with highs in the 70s
and lows in the 40s. By Monday the trough of low pressure will work
on to the plains and with some marginal instability a few
thunderstorms will be possible along with scattered showers. Chances
will be in the mid range. Otherwise expecting breezy conditions
Sunday night into Monday.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 625 PM CDT Tue Sep 27 2016

The primary concern in the 00Z TAF set will be late tonight and
Wednesday morning. MVFR stratus is projected to back in from the
northeast into our eastern zones, primarily in the 10Z to 15Z time
frame. So far it appears that this may impact the KFSD TAF with
MVFR conditions during that time frame before clearing out in the
late morning. At this time, the stratus is forecast to remain east
of KHON and KSUX, however included an MVFR scattered deck at KSUX
early Wednesday as the stratus deck may be very close to that
site.
