Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
1255 AM CDT Sat May 27 2017

Issued at 1248 AM CDT Sat May 27 2017

See below for an aviation forecast discussion for the 06Z TAFs.

UPDATE Issued at 841 PM CDT Fri May 26 2017

Made a few changes to the pops/wx grids but in general the
forecast is going fine.


.SHORT TERM...(This Evening through Sunday Night)
Issued at 320 PM CDT Fri May 26 2017

An upper level low pressure area spinning over the Rockies late this
afternoon already spreading clouds and some rainfall into southwest
SD. All model indications continue to show this rainfall spreading
northeast into the evening and overnight through Pierre and maybe up
to Watertown by morning. The best chances of rainfall will be south
of Pierre. The northern CWA looks like it will miss out with this
system. Otherwise, as this system moves by, daytime heating on
Saturday afternoon will build up some instability. With the help of
some upper level short wave energy, expect some afternoon and
evening showers/storms to develop. Bufkit soundings showing some
weak cape for Saturday afternoon. With northerly flow aloft
remaining through Sunday night, another short wave trough dropping
in straight from the north will clip the eastern part of our region
Sunday afternoon and night bringing some more chances of
showers/storms in the far eastern cwa as weak instability will again
be available. Highs over the next few days look to be mainly around
70 to 75 degrees for both Saturday and Sunday which is near to a few
degrees below normal.

.LONG TERM...(Monday through Friday)
Issued at 317 PM CDT Fri May 26 2017

Not much for change across the extended/next week. There may be a
bit of a cool start to Tuesday, however the rest of next week
appears dry with near average temperatures.


.AVIATION...(For the 06Z TAFS through 06Z Saturday Night)
Issued at 1248 AM CDT Sat May 27 2017

Vfr conditions are expected through Saturday at all terminals.
