What happened

The episode as NWS FSD wrote it up.

A strong upper level wave lifted northeast from the Texas Panhandle early on March 9, reaching the western Great Lakes as an intense closed low. This system included a leading surge of warm air, allowing precipitation to become rain or light freezing rain over a large area, with many locations receiving a few hundredths to two tenths of an inch ice accumulation before colder air wrapped in behind and transitioned precipitation to snowfall. Brief periods of heavier snowfall due to marginally unstable air off the surface led to accumulations of 2 to 6 inches north of Interstate 90 along with travel disruptions, with generally a trace to 2 inches south; the exception being parts of northwest Iowa which received 2 to 4 inches. As the surface low pressure moved across Iowa by later in the afternoon and evening of March 9, northwest winds increased to a gusty 30 to 45 mph.

What forecasters said that day

Area Forecast Discussion
National Weather Service Sioux Falls SD
327 AM CST Sat Mar 9 2019

.SHORT TERM...(Today and Tonight)
Issued at 323 AM CST Sat Mar 9 2019

Main concerns will be an increased threat for icing in far
southeast SD and northwest IA this morning. Snowfall amounts
similar to previous forecast with highest amounts north of
Interstate 90. Once this system is through attention will then
turn to the potentially very wet and windy mid week system which
could bring a number of weather hazards.

A strong system will swing into the area today and bring an
abundance of precipitation types. Temperatures aloft from about
Yankton to Brookings east will be at least a bit above zero for a
period this morning and from about Vermillion to Sioux Falls to
Marshall 2 to 4 degrees C above zero in the warm layer aloft. This
warm layer aloft is in response to a strong wave which was just
beginning to wrap northeast from the panhandle of Texas at 9z. As
this wave wraps north lift will increase significantly and with weak
instability aloft precipitation will be moderate to briefly heavy at
times. The low to mid level forcing will focus along and east of
Interstate 29, especially from mid morning into the afternoon.
Overall precipitation amounts will be about a half an inch to an
inch with much of that shared between snow, freezing rain, sleet and
rain. The best chance for mainly rain this morning will be over
northwest IA but temperatures will be just a bit above freezing at
33 to 34 degrees so still some concern for icing with east winds at
15 to 30 mph this morning. Will bump up the amounts of icing and
focus wording a little more heavily in these areas. Have removed the
warning from south central SD and now have it only north of I-90.
Snowfall amounts will likely struggle a bit in central SD as the
main precipitation shield sets up east of the James River. Still
anticipate snowfall amounts of about 5 to 9 inches within the
warning area, 2 to 5 inches along I-90 and 1 to 3 inches south of
there, possibly just a half an inch from Sioux City to Storm lake.
All of these precipitation amounts have the potential to be variable
depending upon how long the warm layer aloft hangs in.

Drier air will fill in behind the system quickly tonight with strong
winds still anticipated. Will maintain advisories for late tonight
into Sunday morning with the potential for blowing and drifting
snow, although the main threat will likely be drifting snow. After
high temperatures in the 30s today, lows tonight will fall into the
teens and lower 20s.

.LONG TERM...(Sunday through Friday)
Issued at 323 AM CST Sat Mar 9 2019

Sunday into Monday evening looks fairly quiet with weak mid level
ridging building across the area. This is in response to the
deepening wave over the southwest United States. Temperatures will
remain cold during this time with highs mostly in the 20s both
Sunday and Monday and lows 5 to 15 on Monday morning.

This will be the short break before we head into our next period of
unsettled weather. Late Monday night into Tuesday warm advection
will spread across the area as a small piece of energy wraps north
ahead of the main wave. This will bring the threat for a little
light freezing rain in the morning with rain possible from the
morning into the afternoon. Amounts with this wave will likely be
less than a quarter of an inch.

Late Tuesday night into Thursday a colossal wave will deep over the
western high plains and spread northeast. This will bring an
abundance of lift and moisture. Precipitation type still up in the
air but if it ends up close to it's current path we will likely see
mostly rain east of the James River and snow towards central SD. In
fact, if it is all snow could see a potent blizzard with each model
showing 50 to 60 knots of northerly flow at 850 mb with this wind
likely occurring while it is snowing. Too early to start tossing
around any details but needless to say, this mid week system is
massive and may bring a lot of what we do not need which is more
moisture. In areas that see mostly rain there will likely be some
flooding concerns, especially in towns where storm drains are
clogged with snow. Temperatures should be in the 30s and 40s
Tuesday and Wednesday then back into the 20s Thursday and Friday.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1116 PM CST Fri Mar 8 2019

IFR to LIFR conditions are expected through most of the TAF
period. Areas of fog and patchy freezing drizzle continue
overnight, before a wintry mix and snow develop during the morning
on Saturday. Gusty northwest winds will arrive by Saturday
afternoon, causing patchy BLSN.
