Area Forecast Discussion
National Weather Service Aberdeen SD
1149 AM CST Mon Dec 21 2020

.UPDATE...
Issued at 1149 AM CST Mon Dec 21 2020

18z aviation discussion updated below.

UPDATE Issued at 1055 AM CST Mon Dec 21 2020

Very strong northwest winds this morning across the eastern cwa.
These will continue into the early afternoon before dropping off
quickly by mid afternoon. Therefore, the wind advisory looks good
at this time. Otherwise, mixed layer clouds across the east are
expected to diminish into the afternoon. Highs in the upper 30s to
the upper 40s still look good for the day.

UPDATE Issued at 534 AM CST Mon Dec 21 2020

Put out a wind advisory for portions of the area today considering
winds on the sounding were 40 kts at 925 mb with a steady increase
above that. Gusts may still be sporadic. Winds will diminish from
west to east through the afternoon and westernmost counties in the
advisory may be cancelled early.

&&

.SHORT TERM...(Today through Tuesday Afternoon)
Issued at 447 AM CST Mon Dec 21 2020

Breezy northwest winds will continue today as upper trough exits to
the east. Lapse rates will support mixing from a strong jet aloft,
especially along higher elevations like the Coteau. However, suspect
it may be isolated/sporadic like it was yesterday even with the core
of mid level dry air. Winds will diminish by evening as high
pressure briefly builds in. At the same time, ridging will build
back in aloft.

Both the ridge and the winds will support warm temperatures today
and tonight with highs in the upper 30s/40s and lows in the 20s.
Southerly winds pick up early Tuesday across the east on a llj ahead
of an approaching low pressure system. Behind the low, winds will
shift to the northwest and become very gusty again. With the
southerly winds, good mixing, and ridging aloft, Tuesday will be the
warmest day of the week by far and the last warm day for at least a
week. Highs will top out in the 40s in the east to near 60 degrees
in south central SD.

.LONG TERM...(Tuesday Evening through Sunday)
Issued at 447 AM CST Mon Dec 21 2020

A strong area of low pressure crossing the region Tuesday night into
Wednesday will be the main forecast challenge.

There is reasonable agreement among models and ensembles with an
area of low pressure and upper level trough crossing the region
Tuesday night through Wednesday. This system will certainly bring
much colder temperatures, gusty northwesterly winds, and the
potential for light accumulating snowfall. Using the 0Z model
solutions, currently have high confidence the region will experience
much colder temperatures Wednesday and Wednesday night. The actual
high on Wednesday will likely occur shortly after midnight, with
temps falling throughout the day, bottoming out in the signal digits
on either side of zero by Thursday morning.

Currently have moderate to high confident the CWA will see gusty
northwesterly winds with gusts possibly exceeding 45 knots Wednesday
morning. Confident with winds is better over central and south
central areas, or where the NAEFS Return Interval is showing one in
ten years winds at 850 mb. Winds should exceed advisory levels,
perhaps reaching high wind criteria Tuesday night/Wed morning.

There is low to moderate confidence with pcpn and potential snowfall
amounts. A majority of the models now support some pcpn as the cold
front pushes across the region. Timing is slightly different, or
offset by 6 hours with some models. Snowfall amounts is still a big
unknown at this time. The GEFS probability of seeing 2 inches of
snow is 30 percent over the far northeastern portion of the CWA, or
the upslope region of the Sisseton Hills. The prob of 1 inch is 15
to 25 percent for areas along and north Highway 14, with a higher
potential over the Sisseton Hills.  Will a half inch of snow and 40
mph sustained winds cause significant travel issues? Or will the
lack of snow cover limit the impacts? Thankfully, the rest of the
period is dry and uneventful at this time.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1149 AM CST Mon Dec 21 2020

Terminals KABR,KATY,KPIR,KMBG

Very strong northwest winds along with MVFR/low VFR mixed layer
clouds are expected into the afternoon affecting ABR/ATY. As the
surface pressure gradient weakens quickly into the afternoon, expect
the winds to fall off by mid afternoon along with the mixed layer
clouds decreasing. ABR and ATY will then be VFR through the night
and Tuesday morning. PIR and MBG should remain VFR through the
entire forecast. Also, expect llws to develop late tonight into
Tuesday morning from the southwest at most airports.
