What happened

The episode as NWS FSD wrote it up.

Variable snowfall of 2 to 5 inches, northwest winds gusting to 45 mph, and snow cover existing before the storm in part of the area, produced blizzard conditions with visibilities below a quarter mile in blowing snow in many areas. The low visibilities and drifting snow forced some businesses to close, and also forced several school closings on Monday February 11th. The blizzard closed many roads.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Sioux Falls, SD wrote its last area forecast discussion before the first event at Feb 10, 5:50 PM CST, 1 hour 10 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
550 PM CST SUN FEB 10 2013

.DISCUSSION.../ISSUED AT 404 PM CDT/
WINTER STORM UNDERWAY ACROSS THE NORTHERN PLAINS WITH THE SURFACE
LOW TRACKING NORTHEAST ACROSS NORTHWEST IOWA THIS AFTERNOON. LATEST
WATER VAPOR IMAGERY PLACES THE CENTER OF THE UPPER LEVEL CIRCULATION
OVER THE SIOUX FALLS AREA WITH A LARGE AND WELL PRONOUNCED DRY SLOT
COVERING MUCH OF THE AREA ALONG AND EAST OF INTERSTATE 29. WITH THE
COOLER AIR SHIFTING EAST...ANY RAIN OR MIXED PRECIPITATION WILL
SWITCH OVER TO SNOW WITHIN THE NEXT FEW HOURS AND REMAIN AS SNOW
OVERNIGHT. WHILE THE BULK OF THE HEAVY BANDED PRECIPITATION HAS
LIFTED OUT OF THE CWA...WE ARE WATCHING TWO BANDS WHICH HAVE SET UP
ACROSS OUR AREA THIS AFTERNOON.

THE FIRST BAND IS ASSOCIATED WITH A VORT MAX SPINNING UP ON THE
SOUTH SIDE OF THE UPPER LOW ACROSS NORTHWEST IOWA INTO SOUTHWEST
MINNESOTA. MODERATE REFLECTIVITY SUGGESTS THIS BAND MAY BE
CONVECTIVELY ENHANCED...WITH REPORTS WITHIN IT OF A QUICK BURST OF
LARGE WET SNOWFLAKES FOR AREAS ALONG AND NORTH OF I90. EXPECT THE
RAIN OVER NORTHWEST IOWA TO MIX WITH THEN CHANGE TO SNOW INTO THE
EARLY EVENING AS THE BAND LIFTS EAST NORTHEAST.  A SECOND BAND OF
LIGHT TO MODERATE SNOWFALL IS FALLING IN THE WRAP AROUND MOISTURE ON
THE BACK SIDE OF THE SYSTEM  AND VERY SLOWLY ROTATING ACROSS THE
JAMES VALLEY AREA. THIS BAND SHOULD GRADUALLY SHIFT EAST AND NORTH
AS THE LOW TRACKS INTO NORTHERN WISCONSIN BY LATE TONIGHT. THIS WILL
BRING SOME ADDITIONAL ACCUMULATIONS TO THE FORECAST AREA...BUT
OVERALL TREND WILL BE FOR THE SNOW TO TAPER OFF FROM SOUTHWEST TO
NORTHEAST INTO MONDAY MORNING. COULD SEE AN ADDITIONAL INCH OR TWO
FROM THIS ACTIVITY THROUGH TONIGHT WITH LOCALIZED HIGHER AMOUNTS.

THE BIGGEST CONCERN WILL BE THE STRONG WINDS THAT ARE INCREASING
ACROSS OUR WESTERN HALF THIS AFTERNOON. THE STRONG WINDS WILL
QUICKLY SPREAD EAST THROUGH THE REMAINDER OF THE CWA THIS EVENING
AND SHOULD PEAK AROUND 20 TO 30 MPH WITH GUSTS TO 45 MPH. WINDS WILL
DECREASE BEGINNING LATE TONIGHT IN OUR FAR WEST WHILE THE FAR EAST
WILL SEE STRONG WINDS THROUGH THE MORNING HOURS. WITH THE RECENT
HEAVY SNOWS AND ADDITIONAL SNOW FALLING...BLIZZARD CONDITIONS
ALREADY BEING SEEN WEST OF THE JAMES VALLEY WILL SPREAD EAST. MADE A
FEW CHANGES TO THE ONGOING BLIZZARD WARNINGS. HAVE REMOVED
COTTONWOOD...JACKSON AND NOBLES MN AND PLACED THEM IN THE WINTER
WEATHER ADVISORY GIVEN THAT THEY HAVE RECEIVED LITTLE TO NO SNOWFALL
TODAY AND ONLY SOME HEAVY SLUSH AT BEST. ALSO ENDED THE BLIZZARD
WARNING AT 12Z MONDAY FOR MOST OF OUR SD COUNTIES WITH WINDS
DECREASING A BIT FASTER. OTHERWISE HEADLINES LOOK PRETTY GOOD. WHILE
SIOUX FALLS PROPER DID NOT RECEIVE MUCH SNOW TODAY...WESTERN AND
NORTHERN MINNEHAHA COUNTY HAVE REPORTED AT LEAST 3 INCHES SO
FAR...SO WILL LEAVE THE COUNTY IN THE BLIZZARD WARNING WITH THE
BIGGEST CONCERN BEING THESE AREAS. /

WINDS WILL CRASH PRETTY QUICKLY WITH WEAK RIDGE SETTLING ACROSS AREA
DURING MONDAY EVENING...THEN DEVELOP A BETTER WESTERLY COMPONENT LATER
IN THE NIGHT AS PRESSURES FALL ALONG THE INTERNATIONAL BORDER WITH
KICKER WAVE SLIDING TO THE NORTH. THIS WILL MAKE LOWS TOUGH...AS
FRESH SNOWCOVER WILL BE GOOD FOR A RAPID EVENING DECOUPLE...THEN
SHOULD SEE STEADY TO RISING TEMPS...WITH SLOWER RESPONSE FOR LOWER
ELEVATION LOCATIONS. HEALTHIER WESTERLY COMPONENT ON TUESDAY WHICH
WOULD BE QUITE MILD IF NOT FOR THE SNOW COVER. TOOK TEMPS ON A TRIP
TOWARD 925 HPA MIXING FOR NW IA...WHILE BALANCED IMPACT OF NEW
SNOWCOVER WITH INCREASED WEIGHTING TOWARD ISOTHERMAL IN DEEPEST
SNOWCOVER.

SHOULD HAVE INCREASING AMOUNT OF HIGH LEVEL CLOUDS SPILLING OVER THE
RIDGE INTO NORTHERN PLAINS ON TUESDAY NIGHT AND WEDNESDAY. PERHAPS A
WEAK REINFORCING PUSH OF COOLING GLANCING BY THE NORTHEAST WITH
SUPPORT OF WEAK NW FLOW WAVE...BUT OVERALL A MILD PATTERN EVEN
THROUGH WEDNESDAY NIGHT...AS STRONGER CLIPPER WAVE CRASHES THE PARTY
ON WEDNESDAY NIGHT. DEEPEST DIV Q WITH SYSTEM REMAINS TO THE
NORTHEAST AND FAVORS MORE SIGNIFICANT PRECIPITATION OUTSIDE OF AREA
ACROSS MID MINNESOTA. DO HAVE SHARPENING SYSTEM AS IT DIGS TOWARD
THE WESTERN GREAT LAKES BY LATER THURSDAY...AND THIS WILL DRIVE A
MUCH COLDER AIRMASS SOUTHWARD. CARRIED ON WITH SOME CHANCE LEVEL
POPS FOR MAINLY SHALLOW FORCED PRECIP WITH COOLING BEHIND ARCTIC
FRONT...BUT DEEPER LIFT AGAIN REMAINS OFF TO THE NORTHEAST. GFS IS A
BIT TOO STRONG AND TOO FAST FOR TASTE...AND TEMPERED THIS WITH THE
ECMWF. HELD ON THE COOLER AIR A BIT STRONGER AND LONGER IN THE EAST
AS ANOTHER BIT OF SOUTHWARD MOVING TROUGH ENERGY SHOULD SLOW RETREAT
OF COLD CORE. /CHAPMAN

&&

.AVIATION.../FOR THE 00Z TAF ISSUANCE/
SURFACE LOW PRESSURE ASSOCIATED WITH SIGNIFICANT WINTER STORM HAS
MOVED JUST EAST OF OUR FORECAST AREA AT THE START OF THE PERIOD...
CENTERED NEAR KJYG IN SOUTH CENTRAL MN AS OF 11/00Z. AS EXPECTED...
VERY STRONG NORTH-NORTHWEST FLOW HAS DEVELOPED AROUND THE BACK SIDE
OF THIS SYSTEM...WITH SUSTAINED WINDS AROUND 25KTS AND FREQUENT WIND
GUSTS OF 35-40KTS LIKELY THROUGH THE NIGHT AT OUR TAF LOCATIONS. THE
STRONGEST WINDS WILL LINGER ACROSS SOUTHWEST MN INTO MONDAY MORNING
AS WELL...WHILE LOCATIONS ALONG AND WEST OF I-29 BEGIN TO SEE SPEEDS
SLOWLY TAPER OFF THROUGH THE DAY. WINDS WILL HAVE LARGEST IMPACT IN
AREAS WEST AND NORTH OF KFSD...WHERE THE STORM PRODUCED ITS HEAVIEST
SNOWFALL. CONSEQUENTLY WIDESPREAD LIFR VISIBILITY IS EXPECTED DUE TO
BLOWING SNOW IN THESE AREAS...WITH SLOW IMPROVEMENT IN VISIBILITY AS
THE WINDS DIMINISH AND FALLING SNOW MOVES OUT OF THE REGION MONDAY.
MVFR-IFR CEILINGS WILL CONTINUE THROUGH AT LEAST EARLY AFTERNOON...
WITH THE STRATUS EXPECTED TO BECOME SCATTERED ALONG/WEST OF THE
JAMES AND MISSOURI RIVER VALLEYS AFTER 11/20Z.
