Area Forecast Discussion
National Weather Service Aberdeen SD
339 PM CDT Fri Jul 5 2019

.SHORT TERM...(This Evening through Saturday Night)
Issued at 339 PM CDT Fri Jul 5 2019

Mid level meso-vortex still bringing some showers/isold storms to
the far eastern cwa late this afternoon. These are expected to
end/move east into the early evening. Otherwise, new development is
already occurring out west with lift from the next short wave trough
coming in. The ops models and hi-res models all show this activity
continuing/increasing into the evening and night as it moves east.
Most all models show this convection having a hard time making it to
the James Valley and east tonight into early Saturday. Therefore,
have trimmed the pops back across much of the east. Severe weather
also looks like it will remain to our west tonight. After this moves
through, most of Saturday looks to be dry as surface high pressure
ridging builds in with maybe some surface heating isolated
showers/thunder with partly cloudy skies and mainly 70s again for
highs. Surface high pressure should keep it mostly dry Saturday
night with mostly clear skies and light winds. Some thunderstorms
are possible later Saturday night west river with some mid level
waa.

.LONG TERM...(Sunday through Friday)
Issued at 339 PM CDT Fri Jul 5 2019

Expect lows mainly in the 60s, and highs in the upper 70s to upper
80s.

Sunday through Sunday night should be mainly dry. It will be
difficult to shake the isolated/slight chance pops with a trough set
up across and just off the Pacific Northwest through much of this
long term period. We will start of with slight ridging, which will
shift into MN Sunday night, with southwesterly flow returning Monday
as the initial 500mb low over southern British Columbia/northern WA
slowly nears, and moves move across the Dakotas as an open trough
late Tuesday afternoon into early Wednesday morning).

The next chance for stronger to severe storms looks to hold off
until later Monday afternoon into Monday night, with the main threat
being across western ND into north central SD. Expect an elongated
area of low pressure at the surface stretching from northern
Manitoba to along the MT/ND/SD/WY border around daybreak Monday to
move across central SD by 06Z Tuesday, and exit through our MN by
early afternoon. Forecast solutions are pretty consistent with this
idea, so high chance/low likely pops seem reasonable Monday
afternoon through Tuesday. Expect northwest flow Wednesday night
into Friday, before becoming more zonal. While showers and storms
could slide in (especially Friday), mainly dry weather is expected.

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon)
Issued at 1255 PM CDT Fri Jul 5 2019

Upper level low pressure area showers in the ATY area will move out
early this afternoon. Otherwise, expect mixed layer MVFR/low VFR cu
clouds across the region into the early evening. The next short wave
trough coming in from the west will bring another round of
showers/storms this evening and overnight mainly affecting PIR/MBG
at or in the vicinity. Expect some possible IFR/MVFR vsbys and
ceilings in the showers/storms. ABR/ATY should be dry this evening
and overnight.
