Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
623 PM CDT Sat Oct 14 2017

.SHORT TERM...(This Evening through Sunday)
Issued at 302 PM CDT Sat Oct 14 2017

System continues to wrap up overhead with moderate rain, a few
rumbles of thunder and a sprinkling or two of grauple. Back to
the west there remains a band of rain associated with mid level
frontogenesis as well. With all the rain across the area, the low
level atmosphere is expected to be quite saturated, however there
is some lightly drier air upstream so despite clearing overnight
it is still questionable that fog will develop, despite a surface
ridge moving overhead. This feature will result in our winds
having a westerly component, whether northwest or becoming
southwest after passage. Only one CAM supported fog development,
likely under the ridge axis where lighter winds could allow for
favorable conditions before picking back up and mixing out. As
such, will omit any mention of fog overnight but will pass along
to the evening shift as something potentially to watch.

Sunday will be cool, with warm advection but temperatures still
taking their time to moderate. A weak secondary wave will follow,
but result in mostly mid clouds across the east.

.LONG TERM...(Sunday Night through Saturday)
Issued at 302 PM CDT Sat Oct 14 2017

500 mb heights in the 570s and 825mb heights in the +15 - +22C range
through the extended will lead to unseasonably warm temperatures all
week. Highs will climb into the 60s and 70s about 10 to 20 degrees
above climatological averages. Although a few fronts will skim
through the area, the region is expected to remain dry until next


.AVIATION...(For the 00Z TAFS through 00Z Sunday Evening)
Issued at 622 PM CDT Sat Oct 14 2017

The storm that brought widespread rain/mvfr cigs to the region
will continue to move off to the east overnight, with clearing
skies from west to east. The rainfall and clearing skies, along
with light winds may promote patchy fog late tnt and early Sunday.
