The episode as NWS IWX wrote it up.
A late February storm system brought widespread precipitation in the form of mainly freezing rain. Several locations did see periods of sleet during the event, however the ice accumulations posed the greatest threat. Reports of around one quarter inch of ice along with a few tenths of an inch of sleet was reported across parts of northwest Ohio. 10 to 20 mph winds caused additional problems with fallen tree limbs and power lines, causing road closures and power outages. Temperatures rose above freezing during the overnight hours keeping overall damage to a minimum.
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 Northern Indiana wrote its last area forecast discussion before the first event at Feb 24, 6:28 PM EST, 32 minutes earlier.

.SHORT TERM...
SHORT/DELAYED DISCUSSION DUE TO MULTIPLE ISSUES. SLEET AND FREEZING
RAIN HAS BEEN SLOWLY OVERSPREADING ILLINOIS MUCH OF THE DAY. SOME
LOCATIONS IN WESTERN ILLINOIS HAVE ALREADY REPORTED UPWARDS OF A
HALF INCH OF ICE. OVER THE PAST HOUR THE AREA OF PRECIP HAS
ACCELERATED NE AND HAS REACHED WHITE COUNTY WITH A MIXTURE OF SLEET
AND RAIN. WARMER SFC TEMPERATURES ALREADY POISED TO MOVE INTO FAR
SOUTHWEST COUNTIES POSSIBLY BY THE OVERNIGHT HOURS. INCREASINGLY
DIFFICULT FORECAST AS A RESULT...REQUIRING EXPANDING THE ICE STORM
WARNING FURTHER NORTH TO ALONG AND SOUTH OF US 6. ICE ACCUMULATIONS
OF ONE HALF TO THREE QUARTERS OF AN INCH OR MORE ARE
EXPECTED...ESPECIALLY ACROSS THE NORTHERN HALF OF THE ICE STORM
WARNING AREA. WHILE ACCUMULATIONS WILL BE HEAVY FURTHER
SOUTH...TEMPS POSSIBLY CLIMBING ABOVE FREEZING WILL ALLOW A STOP TO
THE ACCUMULATION OF ICE. EXACTLY WHEN THIS OCCURS REMAINS IN
QUESTION...HENCE NO CHANGES TO THE WARNING. FURTHER NORTH...MIXTURE
OF SNOW...SLEET AND FREEZING RAIN WILL CAUSE LOTS OF PROBLEMS. ICE
ACCUMS OF UP TO QUARTER INCH AS WELL AS SLEET UP TO ONE HALF INCH
ARE EXPECTED TONIGHT. IF TREND CONTINUES ON WARMER AIR BEING DRAWN
NORTH...THEN SIGNIFICANT ICING COULD ALSO OCCUR ACROSS THE WINTER
STORM WARNING AREA.
ON SUNDAY...GRIDS CHANGED TO REFLECT THE WARMER AIR ARRIVING WITH
EITHER RAIN OR RAIN/SNOW EVENTUALLY DOMINATING SOUTHERN QUARTER TO
HALF OF CWA. WILL LEAVE REST OF DETAILS TO LATER SHIFTS.
&&
.LONG TERM...
SUNDAY NIGHT THROUGH SATURDAY...
FORECAST PERIOD BEGINS WITH STACKED SYSTEM OVER THE AREA. MODELS
DIFFERING ON EXACT PLACEMENT WITH NAM FURTHER WEST BACK OVER IOWA
AND ILLINOIS SUNDAY NIGHT AND GFS OVER SOUTHERN GREAT LAKES. MODEL
SOUNDINGS INDICATING SE CWA MAY SEE BRIEF PERIOD OF LIQUID PRECIP IN
THE EVENING BEFORE CHANGING TO SNOW OTHERWISE GOING FORECAST OF SNOW
REST OF CWA LOOKS GOOD. STACKED SYSTEM REMAINS OVER THE AREA
MONDAY...NOT LOOKING FOR MUCH DIURNAL CHANGE IN TEMPS SO WILL KEEP
HIGHS NEAR FREEZING OVER CWA...COLUMN SATURATED THROUGH 700MB AND
SUFFICIENTLY COLD TO SUPPORT ICE PRODUCTION AT CLOUD LEVEL SO SHOULD
BE ALL SNOW EVEN IF SOME LOCATIONS MANAGE TO NUDGE ABOVE FREEZING.
SYSTEM EVENTUALLY KICKS EAST ALLOWING FOR UPSTREAM RIDGING TO WORK
INTO THE AREA GIVING DRY FCST TUE NITE AND WEDNESDAY. NEXT SYSTEM
THEN DIGS INTO THE PLAINS BRINGING ANOTHER CHANCE FOR PRECIP
THURSDAY AND FRIDAY. WILL STAY WITH CURRENT GRIDS RA/SN MIX DURING
THE AFTERNOON AND SN NITE/MORNING HOURS. EXPECT TEMPS 5-10 BELOW
NORMAL TUE THEN NEAR NORMAL REMAINDER OF EXTENDED....WITH BEST
CHANCE OF ABOVE NORMAL TEMPS ON THU IN ADVANCE OF NEXT SYSTEM.
