Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
505 PM MDT SUN SEP 4 2016

.SHORT TERM...(This Evening Through Monday Night)
Issued at 207 PM MDT Sun Sep 4 2016

Mean western conus trough and associated impulses will continue
to affect the region in the period. A potent front side impulse is
in the process of advecting toward the region this afternoon with
flow increasing in the mid levels ahead of this feature.
Destabilization will continue this afternoon and evening with
convection developing and becoming more numerous through evening.
Strong flow will support deep layer shear in excess of 50 knots
with mean ll cape of 1-2.5 KJ/Kg, highest over scentral
SD...supporting a good chance of severe storms over the se half.
Initial convection over the far sw will likely be single
cell/supercells. Convection will quickly organize into a linear
connective system (given wind profiles aloft) with large hail and
damaging winds possible as it progresses across the se third.
Outside of this area, mainly sct showers and few isold ts will be
possible. Convection chances will continue through the night as
the main jet streak and upper trough lifts over the region. Patchy
fog will also be possible tonight, esp across the western third.
Cyclonic flow will remain over the region through Monday, with
additional diurnal shra/ts possible, best chance across the far nw
closest to the best lsa. Cooler conds expected nw 2/3 with highs
slightly below seasonal norms most areas, coolest over far nw
areas.

.LONG TERM...(Tuesday Through Sunday)
Issued at 207 PM MDT Sun Sep 4 2016

Slow moving upper trof to the west of the region will finally
start moving east across the Rockies and plains Tuesday and
Wednesday. Good chances for showers and a few storms will
continue, with the best chances looking to be Tuesday night into
Wednesday morning. As trof moves east of the area late in the
week, drier zonal flow aloft will develop. Will still keep low
chances for showers in some areas late Thursday through Friday.
Temperatures will be near or slightly below seasonal averages
through the period, with highs mostly in the 70s.

.AVIATION...(For the 00Z TAFS Through 00Z Monday Evening)
Issued At 502 PM MDT Sun Sep 4 2016

Expect showers and thunderstorms this evening with areas MVFR/IFR
CIGS/VSBYS at times. Severe storms with large hail and damaging
winds are possible over southern SD. After 06z, precipitation will
be on the wane with patchy IFR VSBYS developing due to BR along
with MVFR CIGS overspreading much of the area lasting into Monday.
