Area Forecast Discussion
National Weather Service Aberdeen SD
326 AM CDT Wed Jul 26 2017

.SHORT TERM...(Today through Friday Afternoon)
Issued at 325 AM CDT Wed Jul 26 2017

Still a few echoes showing up on the radar this morning, so may be a
few sprinkles or light showers into the morning hours. Surface high
pressure will begin to drop southward over the area by midday or so,
then looks to become the dominant feature through late Thursday
night before getting pushed eastward on Friday as low pressure
approaches from the west. After this morning`s lingering
precipitation chances, will see dry conditions through the remainder
of the short term period. May see some increase in cloud cover
during the day Friday ahead of the low and in association with a
weak mid level shortwave tracking across the area.

Temperatures will be right around normal through the period, with
highs mainly in the 80s and overnight lows in the upper 50s to mid 60s.

.LONG TERM...(Friday Evening through Tuesday)
Issued at 325 AM CDT Wed Jul 26 2017

The Southern Plains mid level high is expected to gradually shift
west during the period as the mid level ridge over the western
conus begins to amplify. This pattern will bring west to northwest
flow aloft to the region. Northwest flow is always tricky,
especially concerning timing of energy through the flow, and on
that count the deterministic models are only broadly similar. One
thing is a bit more certain, temperatures should average out right
around normal since the warmest air sfc/aloft is expected to
reside over the western high plains.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1227 AM CDT Wed Jul 26 2017

VFR conditions are expected at all locations through tonight and
Wednesday. Showers and thunderstorms are expected to affect ATY
tonight at or in the vicinity with possible MVFR conditions.
