An intense storm system that helped spawn killer tornadoes over the Tennessee Valley brought areas of heavy snow and blowing snow to southeast Nebraska and southwest Iowa. The system tracked from the Texas panhandle to the lower great lakes region and pulled up 50 and 60 degree surface dew points into southeast Missouri and southern Illinois.

The episode as NWS OAX wrote it up.
An intense storm system that helped spawn killer tornadoes over the Tennessee Valley brought areas of heavy snow and blowing snow to southeast Nebraska and southwest Iowa. The system tracked from the Texas panhandle to the lower great lakes region and pulled up 50 and 60 degree surface dew points into southeast Missouri and southern Illinois.
Snow from this system began around sunrise Tuesday morning February 5th and lasted until mid morning on the 6th. Around 6 inches of snow fell over much of Montgomery county, and north winds that frequently gusted over 25 mph caused significant blowing and drifting snow. Some schools across the area were closed on the 6th.
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 Omaha, NE wrote its last area forecast discussion before the first event at Feb 5, 3:34 AM CST, 4 hours 41 minutes earlier.

334 AM CST TUE FEB 5 2008
.DISCUSSION...
MAIN FORECAST CHALLENGE IS POTENTIAL FOR HEAVY SNOW IN SRN COUNTIES.
LATEST WATER VAPOR IMAGERY AND RUC ANALYSIS FEATURE AMPLIFYING
TROF OVR FOUR CORNERS REGION WITH IMPRESSIVE UPPER JET STREAK OUT
AHEAD OF THE TROF. LATEST MSAS SFC ANALYSIS SHOWS LOW PRES
CENTERED OVR NRN TX WITH WMFNT EXTENDING INTO NERN OK. PCPN
CONTINUES TO SPREAD NEWD ACROSS WRN KS AND INTO CNTRL NEB IN
ASSOCIATION WITH STRONG UPPER LEVEL DIVERGENCE IN RIGHT ENTRANCE
REGION OF JET STREAK. IN ADDITION...STRONG MID LEVEL FRONTOGENESIS
OFF RUC ANALYSIS /700-500MB/ LINES UP WELL WITH PCPN BAND. AS JET
STREAK MOVES NEWD OUT AHEAD OF POTENT UPPER TROF...EXPECT PCPN TO
SPREAD NORTHEAST ACROSS MUCH OF THE FORECAST AREA THIS MORNING.
THIS WILL BE FIRST WAVE OF PCPN FOR THE AREA. BUFKIT FORECAST
SOUNDINGS SHOW PCPN TYPE AS SNOW OVER MOST OF THE AREA...EXCEPT
ACROSS FAR SERN NEB AND SWRN IA WHERE A FREEZING RAIN/SLEET/SNOW
MIX IS POSSIBLE UNTIL 18Z. AFTER THIS TIME...PCPN TYPE EXPECTED TO
BE ALL SNOW FOR ALL AREAS.
SECOND WAVE OF PCPN...WHICH MAY VERY WELL BLEND INTO THE
FIRST...WILL COME AS BROAD AREA OF LARGE SCALE ASCENT INCREASES
AHEAD OF APPROACHING UPPER TROF THIS AFTERNOON. IN
ADDITION...CROSS SECTIONS SHOW DEEP FRONTOGENETIC CIRCULATION WITH
STRONG OMEGA ON TOP OF CIRCULATION ACROSS SOUTHEASTERN NEB AND
SWRN IA. WEAK STATIC STABILITY INDICATED BY LARGE AREA OF NEGATIVE
EPV...ESPECIALLY ACROSS SERN NEB/SWRN IA AND POINTS SWD...ALONG
WITH NEGATIVE THETA-E LAPSE RATES INDICATE CONVECTIVE SNOW QUITE
LIKELY. DUE TO FOLDING OF THETA-E SFC...UPRIGHT INSTABILITY MORE
LIKELY THAN CSI WHICH WL LIKELY PRODUCE MORE INTENSE PCPN RATES
ACROSS OUR FAR SRN COUNTIES. RATES OF 2/HR NOT OUT OF THE
QUESTION AT TIMES BETWEEN 21Z/TUE AND 06Z/WED. HAVE UPGRADED THE
ADVISORY ACROSS SOUTHERN COUNTIES TO A WINTER STORM WARNING. 6-8
POSSIBLE IN THIS WARNING AREA WITH AN ISOLATED 10 NOT ENTIRELY
OUT OF THE QUESTION GIVEN THE LARGE AREA OF NEGATIVE EPV. WL
CONTINUE ADVISORY FOR POINTS NORTH AS PREVIOUSLY FORECAST WITH
AMOUNTS RANGING FROM 3-5 BASED ON SPECIFIC HUMIDITY CALCULATIONS
AND WITH A NEAR 1:12 RATIO. SNOWFALL AMOUNTS EXPECTED TO TAPER OFF
TO THE NORTH WITH AROUND AN INCH TOTAL ALONG A LINE FM ALBION TO
NORFOLK TO ONAWA IOWA...AND LESS THAN AN INCH NORTH OF THAT LINE.
HEAVIEST SNOWFALL RATES IN BOTH LNK AND OMA METRO AREAS EXPECTED
TO BE BETWEEN HOURS OF 18Z/TUE AND 03Z WED IN ASSOCIATION WITH
FRONTOGENETIC BAND AND STRONG LARGE SCALE ASCENT.
DUE TO MOISTURE ASSOCIATED WITH THIS SYSTEM...EXPECTING A HEAVIER
WET SNOW INITIALLY VERSUS LIGHT AND FLUFFY. WITH SFC WINDS AROUND 15
TO 25 MPH...NOT EXPECTING TOO MUCH TROUBLE WITH REDUCED VISIBILITIES
DUE TO BLOWING SNOW. DRIFTING MAY BE AN ISSUE LATER IN THE
DAY/EVENING AS SNOW ACCUMULATES MORE RAPIDLY AND TEMPS DROP. WL GO
WITH A NON-DIURNAL TEMPERATURE RANGE TODAY WITH TEMPS SLOWLY
DROPPING INTO THE 20S BY AFTERNOON.
OF NOTE...GFS SEEMS RATHER FAST WITH THIS SYSTEM. WE HAVE GONE WITH
A NAM/ECMWF BLEND FOR SPEED WHICH 03Z SREF AGREES WITH AND THEREFORE
HAVE LINGERED PCPN LONGER INTO WED MORNING.
SHORTWAVE RIDGING MOVES IN LATER IN DAY ON WED. LEFT SMALL CHANCES
OF PCPN IN FOR EARLY THURSDAY AS TROF MOVES THRU NWRLY FLOW. LEFT
REMAINDER OF FORECAST UNCHANGED EXCEPT WE DID DROP TEMPS ON
SATURDAY DUE TO ARCTIC AIR MAKING ITS WAY SWD. DAY SHIFT WILL
ASSESS FURTHER...BUT WANTED TO GET A LITTLE START ON THE COLD AIR
FOR THE WEEKEND.
&&
.AVIATION...
FOR TAF SITES KOMA/KLNK/KOFK...THRU 06Z/06TH.
EXPECT CIGS TO FLUCTUATE FOR A WHILE BETWEEN LOW END MVFR AND IFR AS
A SECOND SURGE OF COLD AIR THAT BROUGHT CIGS DOWN AT OFK BETWEEN 06Z
AND 07Z REACHES OMA AND LNK ARND 12Z. SNOW IS EXPECTED TO DVLP ARND
15Z...BUT HEAVIER BANDED SNOW WILL MORE LIKELY AFFECT OMA AND LNK
BETWEEN 18Z AND 03Z WITH INTERMITTENT MDT SNOW AND LOW CIGS/VSBYS
DURING THAT PD. OFK SHOULD SEE LIGHTER SNOW BUT PREVAILING IFR
CONDITIONS AFTER 15Z WITH SOME IMPROVEMENT AFTER 00Z.
