Area Forecast Discussion
National Weather Service Aberdeen SD
321 PM CDT SUN SEP 25 2016

.SHORT TERM...(This Evening through Tuesday Night)
Issued at 321 PM CDT SUN SEP 25 2016

Winds will diminish after sunset this evening as low pressure
continues to move away from the region. Cool temperatures can be
expected overnight, but just enough of a gradient will keep a breeze
going through the night, thus preventing a free-fall with temps.
Mainly upper 30s and low 40s are forecast. On Monday, breezy
conditions will develop once again, mainly for eastern areas.
Although, speeds will not be as strong as they were today,
especially for central SD. Surface high pressure moves in Monday
night with winds becoming light, especially for areas along and west
of the James River. Will likely see some 30s for lows, but not too
concerned about frost at this point as current forecast has mainly
upper 30s to low 40s. Another chilly night in store for eastern
areas Tuesday night with the ridge axis still in place. Went a bit
cooler over the east and believe temps could even get a few degrees
cooler. But again, readings still look warm enough to where
widespread frost still looks unlikely.

.LONG TERM...(Wednesday through Sunday)
Issued at 321 PM CDT SUN SEP 25 2016

Upper ridging over the Plains will keep high temperatures in the
70s through the extended. Dry conditions will allow for lows to fall
into the 30s and 40s. Models keep delaying the progression of a sfc
low off the Rockies and into the Plains. Until this occurs, there is
no good chance of precip. At the moment, consensus begins
introducing pops Sat night.


.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1228 PM CDT SUN SEP 25 2016

An area of mvfr stratus associated with an exiting cold front
continues to impact KATY. This cloud deck will continue to move
east and should clear KATY by 21z leaving all sites VFR for the
remainder of the period. Gusty northwest winds of 20 to 40 kts
will slowly diminish this evening before increasing back to 15 to
25 kts on Monday.
