The episode as NWS ILN wrote it up.
On Sunday and Monday March 24th and 25th, snow and sleet along with some rain spread through the region, with significant snow found over metropolitan Dayton and to the northwest. Surface low pressure moved from the Tennessee Valley to Ohio during the overnight. This low got added influence with an upper low tracking east through Kentucky during the late night and early part of Monday. The system occluded over the state and large snowfall amounts were recorded north and west of Dayton. Drier air in the occlusion was pulled into central Ohio, limiting snowfall totals significantly in this area. Much of the early part of the event started as rain in the southern portion of the CWA and snow totals were notably lower in southern Ohio, southeast Indiana, and northern Kentucky.
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 Wilmington, OH wrote its last area forecast discussion before the first event at Mar 24, 9:01 PM EST, 59 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1001 PM EDT SUN MAR 24 2013
.SYNOPSIS...
LOW PRESSURE AT THE SURFACE WILL TRACK FROM THE TENNESSEE VALLEY
INTO OHIO TONIGHT AS AN UPPER LOW MOVES EAST THROUGH KENTUCKY. THE
LOW WILL TRANSLATE EAST OVER THE APPALACHIANS ON MONDAY. NORTHWEST
FLOW WILL KEEP COOLER AIR AND SOME LINGERING SHOWERS OVER THE
REGION THROUGH MID WEEK.
&&
.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
HEAVIER BAND HAS PIVOTED NORTH OF THE IMMEDIATE CINCINNATI AREA.
WE ARE SEEING SOME REDEVELOPMENT UNDER THE UPPER LEVEL LOW ACROSS
CENTRAL KENTUCKY AND THIS COULD EXPAND SOME THROUGH THE OVERNIGHT
HOURS. MEANWHILE...DEFORMATION BAND WILL SLOWLY PIVOT AROUND THE
LOW LATER TONIGHT AND EVENTUALLY WORK BACK IN TOWARD CINCINNATI
THROUGH DAYBREAK. EVEN WITH THAT THOUGH...THINK IT WILL BE HARD TO
ACHIEVE WARNING CRITERIA A WE JUST DID NOT GET THAT MUCH
SNOW ACCUMULATION WITH THE INITIAL SURGE OF MOISTURE EARLIER THIS
EVENING. HAVE THEREFORE DOWNGRADED THE WARNING TO AN ADVISORY ACROSS
PARTS OF OUR SOUTHWEST. WILL ALSO TRIM BACK ON ACCUMULATIONS FROM
FRANKLIN COUNTY INDIANA OVER TO CLINTON COUNTY...BUT LEAVE
WARNING UP AS THEY MAY STILL END UP ON THE SOUTHERN FRINGE OF THE
PIVOTING DEFORMATION AXIS. ELSEWHERE...ACROSS THE NORTH HAVE ALSO
TWEAKED DOWN ACCUMULATIONS A BIT...BUT WILL NOT MAKE ANY CHANGES
TO THE HEADLINES.
&&
.SHORT TERM /MIDNIGHT TONIGHT THROUGH TUESDAY NIGHT/...
HEAVIEST BANDS OF SNOW WILL HAVE MOVED EAST WITH THE EXITING AND
WEAKENING UPPER LEVEL LOW. NORTHERLY FLOW WILL SET UP AND
ADDITIONAL ACCUMULATIONS OF AN INCH OR TWO WILL BE POSSIBLE IN
THE INSTABILITY SHOWERS THAT SET UP WITH FAVORED FETCHES OFF OF
THE GREAT LAKES. TEMPERATURES MAY WARM ENOUGH ON MONDAY AFTERNOON
AND ESPECIALLY TUESDAY AFTERNOON THAT ANY SHOWERS PRESENT WOULD
MIX WITH AND POSSIBLY CHANGE TO RAIN FOR A PERIOD OF TIME.
WITH THE FRESH SNOW PACK EXPECTED...TEMPERATURE FORECAST UNDERCUTS
GUIDANCE BY A COUPLE OF DEGREES. HIGH SUN ANGLE EVEN THROUGH THE
CLOUD DECK WILL BATTLE THE COOLER AIR...GIVING A HIGH MARGIN OF
ERROR/CHANGEABILITY TO THE TEMPERATURE FORECAST OVER THE NEXT DAY
OR TWO. THE INSOLATION DURING THE DAY WILL QUICKLY LET ANY SHOWERS
IN THE EVENING TRANSITION QUICKLY BACK TO SNOW DURING THE
OVERNIGHT PERIODS.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
AT THE BEGINNING OF THE PERIOD THE FORECAST AREA REMAINS UNDER
THE WESTERN EDGE OF THE STORM SYSTEM THAT AFFECTED THE REGION
MONDAY AND TUESDAY. CYCLONIC FLOW ACROSS THE REGION WILL COMBINE
WITH CAA TO PRODUCE CONTINUED SCT SHSN. SOME SRN LOCATIONS MIGHT
WARM ENOUGH TO SEE SOME OF THE SHOWERS CHANGE OVER TO RAIN
SHOWERS. ANY LINGERING SHOWER ACTIVITY WILL DIMINISH AS THE NIGHT
PROGRESSES WEDNESDAY NIGHT.
HIGH PRESSURE RIDGE FINALLY BUILDS IN ON THURSDAY. HOWEVER A
DISTURBANCE IN THE NW ALOFT SWINGS ACROSS KENTUCKY PRODUCING AN AREA
OF PCPN. AT THIS TIME IT LOOKS LIKE THE PCPN WILL STAY S AND W OF
THE FA.
WEAK HIGH PRESSURE RIDGE WORKS BACK IN FOR SATURDAY. THEN FOR SUNDAY
GFS AND ECMWF ARE SHOWING SOME SPREAD. THE GFS IS QUICKER WITH A
CDFNT AND SHRA THAN THE ECMWF. WENT WITH BLEND AND PUT A CHC OF SHRA
ON SUNDAY.
FOR TEMPERATURES STAYED BELOW THE GUIDANCE AT THE BEGINNING OF THE
PERIOD. KEPT THE MAJORITY OF THE HIGHS IN THE MID TO UPPER 30S ON
THURSDAY...WHICH IS WELL BELOW NORMAL. AFTER LOWS FALL INTO THE
LOWER TO MID 20S WEDNESDAY NIGHT A GRADUAL WARMUP STARTS. HIGHS
WILL WORK INTO THE UPPER 30S TO MID 40S ON THURSDAY AND THE MID TO
UPPER 40S ON FRIDAY AND SATURDAY. WENT AHEAD AND PUT HIGHS IN THE
50S FOR EASTER SUNDAY.
&&
.AVIATION /02Z MONDAY THROUGH FRIDAY/...
FIRST BAND OF PRECIPITATION WILL CONTINUE TO MOVE TO THE EAST
THROUGH THE TAF SITES THIS AFTERNOON. MOST OF THIS PRECIPITATION AT
KILN...KCMH...KLCK...AND KDAY WILL IN THE FORM OF SNOW. AT KCVG
AND KLUK SOME LIGHT RAIN WILL BE POSSIBLE THIS AFTERNOON. THERE
WILL BE A LULL OR A DECREASE IN INTENSITY OF PRECIPITATION LATER
THIS AFTERNOON AFTER THIS INITIAL BAND. THE NEXT WAVE WILL BEGIN
TO MOVE INTO THE TAF SITES THIS EVENING. MOST OF THIS
PRECIPITATION WILL BE IN THE FORM OF SNOW AGAIN HOWEVER A BRIEF
MIX OF RAIN AND SNOW MAY ALSO BE POSSIBLE AT KCVG...KLUK...AND
KILN THIS EVENING. SNOW WILL BE HEAVY AT TIMES THIS EVENING INTO

TAF PERIOD. GENERALLY THERE ARE SOME LOWER CIGS ASSOCIATED WITH
AND JUST BEHIND THE BAND OF PRECIPITATION THIS AFTERNOON. CIGS

THE AREA OF LOW PRESSURE APPROACHES THE AREA EXPECT CIGS TO LOWER
INTO THE IFR RANGE FOR A LARGE PORTION OF THE OVERNIGHT HOURS.
