National Weather Service Aberdeen SD
241 PM CDT Tue Apr 13 2021

.SHORT TERM...(This Evening through Wednesday Night)
Issued at 239 PM CDT Tue Apr 13 2021

Cold conditions to continue through the short term forecast.
Meanwhile, the upper system over the upper Mississippi River valley
that`s been responsible for all the cold air and pcpn will gradually
start to shear off to the east over the next 12-36hrs. One more wave
rotating around the upper low will move through the northeast CWA
tonight, with more light snow expected. Again, some light
accumulations appear possible over especially the Glacial Lakes
region. As the low pulls away, mid-level ridging will bring mainly
dry conditions to the forecast area for Wednesday and Thursday. As
for temperatures, they`re gonna remain below average yet for a
couple more days as the cold airmass gradually moderates across the
Northern Plains.

.LONG TERM...(Thursday through Tuesday)
Issued at 239 PM CDT Tue Apr 13 2021

The period starts out with the region between two upper level lows
with a trough off to the northwest over Saskatchewan. One low will
be situated over the central Rockies and one over the Great Lakes
region.  The western low will gradually open up and weaken as it
progresses eastward across the area Thursday through Thursday night.
Light precipitation in the form of both light rain and snow will
accompany this system Thursday night into Friday, although will be
limited mostly to areas along and west of the Missouri River. Light
snow accumulations are possible mainly west river.  As the weakened
upper low moves out of the area, the Saskatchewan trough will dig in
behind it Friday night, although no additional precipitation is
expected with this system.

Beyond the precipitation chances Thursday night into Friday, the
extended period looks mostly dry and cool.  Highs will generally be
in the 40s with Sunday being the main exception.  Temperatures
Sunday will be much closer to average with highs in the 50s across
most of the area.
