What happened

The episode as NWS ILN wrote it up.

Surface low pressure tracked from the southern Appalachians to western Virginia by Saturday March 8th. A deepening upper level trough worked into the Ohio Valley overnight, combining with the surface low and strengthening the entire system. The surface pressure gradient tightened in response to the upper low, and gusts of 30 to 40 mph brought blizzard-like conditions to the region.

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 Wilmington, OH wrote its last area forecast discussion before the first event at Mar 7, 10:44 AM EST, 1 hour 16 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1044 AM EST FRI MAR 7 2008

.SYNOPSIS...
LOW PRESSURE ALONG THE GULF COAST WILL MOVE NORTHEAST ALONG THE
APPALACHIANS TONIGHT INTO SATURDAY. THIS MAJOR SYSTEM WILL BRING
SIGNIFICANT WINTER WEATHER TO THE REGION...WITH THE POTENTIAL FOR
HEAVY SNOWFALL TODAY INTO SATURDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
DEEP LONG WAVE TROF EXTENDING SOUTH INTO THE SOUTHERN PLAINS. A
MOIST SOUTHWESTERLY FLOW ALOFT OVERSPREADING COLD AIR IN THE LOW
LEVELS OVER THE OHIO VALLEY. WATER VAPOR IMAGERY INDICATES A
DISTINCT SHORT WAVE OVER WESTERN TN EMBEDDED IN THE SOUTHWESTERLY
FLOW ALOFT. VERY FAVORABLE ISENTROPIC LIFT HAS DEVELOPED...ALONG
WITH FAVORABLE 800-850MB FRONTOGENETIC FORCING AHD OF THIS S/W.
THIS HAS LEAD TO THE DEVELOPMENT OF WIDESPREAD SNOW ACRS MOST OF
THE FA WITH MIX OVER THE FAR SE. TEMPS ARE DROPPING WITH THE SNOW
DUE TO EVAPORATIVE COOLING. THIS HAS LED TO A MORE EFFICIENT TEMP
FOR ACCUMULATING SNOW. ALREADY GETTING REPORTS OF 1 TO 1.5 INCHES
OF SNOWFALL OVER THE SW PORTION OF FA. DUE TO THE STRONG LIFT AND
TEMP PROFILE...HAVE BUMPED UP SNOWFALL DURING THE DAY TODAY TO 1
TO 3 INCHES FAR NW TO 3 TO 5 INCHES SW. HAVE ALSO SPED UP ALL
HEADLINES TO BEGIN NOW.

EXPECT A MINOR LULL IN PRECIP ACTIVITY GENERALLY THIS EVENING IN
THE WAKE OF THIS INITIAL SHORTWAVE. SO HAVE KNOCKED THIS EVENINGS
SNOWFALL DOWN SLIGHTLY WITH HEAVIER PRECIP RE-DEVELOPING LATE
TONIGHT INTO EARLY SATURDAY AS 700 MB LOW PRESSURE TRACKS INTO
SW OH. BASED ON THIS...OVERALL SNOWFALL TOTALS HAVE ONLY MINOR
ADJUSTMENTS TO SNOWFALL TOTALS THRU SAT AFTN WITH THE HEAVIEST
TOTAL OF 12 TO 15 INCHES FROM CVG TO ILN TO CMH.

&&

.SHORT TERM /SATURDAY/...
MODELS HAVE COME INTO GOOD AGREEMENT WITH TRACK AND INTENSITY OF
THE SFC TONIGHT INTO SAT...PUSHING IT INTO WRN NC BY 12Z SAT...AND
INTO PA/NY BY 00Z SUN. ALL MIXED PCPN SHOULD CHANGE TO SNOW
RELATIVELY QUICKLY THIS EVENING.

MODELS DIFFER A LITTLE ON TIMING OF THE HEAVIEST PCPN. THE NAM WAS
QUICKER TO BRING IN A LITTLE HEAVIER SNOW THIS AFTN. I PREFERRED
THE GFS SOLUTION WITH HAD A LITTLE HEAVIER SNOW LATE TONIGHT INTO
SAT...AS H5 LOW GOES NEGATIVE TILT AS IT GOES BY.

EITHER WAY THE SNOW TOTALS WERE SCARILY CLOSE BY THE END OF
SATURDAY. 12-15 INCHES ALONG I-71 FROM JUST N OF HAMILTON CO UP
THRU COLUMBUS METRO. A 10-12 INCH SWATH ON THE EDGE OF THAT. SEE
5-7 INCHES IN MERCER CO OH AND 8-10 IN LEWIS AND SCIOTO.

AS LOW GOES BY TONIGHT...WINDS WILL INCREASE AND WILL CAUSE
BLOWING AND DRIFTING SNOW PROBLEMS...SO ADDED THAT TO THE ZONES.

SPED UP THE EXITING OF THE SNOW ON SAT...ONLY LINGERING A 20 POP
IN THE EXTREME E AND NE. HIGH PRESSURE RIDGE BUILDS IN TEMPORARILY
ON SUNDAY MORNING. H5 LOW DROPPING INTO ERN US TROF WILL BRING A
WEAK CLIPPER LATE SUNDAY INTO SUNDAY NIGHT ACROSS THE REGION. UPPED
POPS WITH THIS CLIPPER. SHOULD ONLY SEE ABOUT AN INCH OF SNOW.

WENT TOWARDS THE WARMER MAV TEMPS TONIGHT. DONT SEE A REAL COLD
NIGHT WITH THE SNOW AND CLOUDS. HIGHS ON SAT WERE A BLEND OF
GUIDANCE...THEN WENT SEVERAL DEGREES BELOW ALL GUIDANCE FOR LOW
SAT NGT...WITH FRESH SNOW COVER.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE SHOULD THEN DOMINATE THROUGH WEDNESDAY NIGHT WHEN
ANOTHER WEAK DISTURBANCE WILL APPROACH THE AREA FROM THE
NORTHWEST. THIS SYSTEM LOOKS TO PROVIDE A BETTER CHANCE FOR
PRECIPITATION THAN THE SYSTEM ON SUNDAY...ALTHOUGH A LACK OF
SIGNIFICANT MOISTURE APPEARS TO BE AN INHIBITOR. THIS SYSTEM TOO
WILL BRING A MIX OF RAIN AND SNOW TO THE AREA FOR TUESDAY AND
TUESDAY NIGHT. HIGH PRESSURE WILL MOVE IN AGAIN FOR WEDNESDAY AND
WEDNESDAY NIGHT. BUT YET ANOTHER SYSTEM WILL MOVE TOWARD OUR
REGION FROM THE NORTHWEST...BRINGING AGAIN A MIX OF SNOW AND RAIN
TO THE AREA FOR THURSDAY.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
MORNING FORECAST WAS CHANGED VERY LITTLE FROM PREVIOUS ISSUANCE.
LARGE AREA OF SNOW WILL WORK NNE FROM TN VLY TO OHVLY THIS
MORNING. DO NOT EXPECT THE RAIN/SNOW LINE TO WORK INTO CVG/ILN
LINE BUT IT MAY PUSH CLOSE...TO WITHIN 25-50 MILES OR SO. ENOUGH
COLD AIR SHOULD BE IN PLACE EARLY TODAY TO LIMIT ANY NRLY PUSH OF
WARM AIR. WINDS HAVE ALREADY BEGUN TO GUST AND HIGHER
REFLECTIVITIES ON THE RADAR WILL INDICATE THE QUICKLY MOISTENING
COLUMN OF AIR AND ONSET OF SNOW. TRIED TO ANNOTATE THE START TIMES
N OF KCVG/KLUK AROUND 14Z WITH HEAVIER SNOW AFTER ABOUT
16Z...ABOUT AN HOUR LATER THAN THIS IN CENTRAL OHIO CMH/LCK TAF
SITES. A VERY SLIGHT SHIFT IN WINDS TO JUST WEST OF N WILL OCCUR
EARLY TOMORROW. BELIEVE THAT THE STRENGTH OF THE GUSTS AND
SUSTAINED WIND WILL ALSO DROP DOWN TOWARDS DAYBREAK. TOOK A
GENERIC 10Z TIME FOR ALL SITES TO DIMINISH SLIGHTLY IN SPEED AND
SUBSEQUENTLY RAISED VSBYS FROM LIFR TO IFR. CIGS WILL STILL BE
VERY DIFFICULT TO PIN SO I DID NOT STRAY FROM THE VV005 THAT WAS
PRESENTED EARLIER.

OUTLOOK...LIFR CEILINGS AND VISIBILITIES ARE EXPECTED INTO
SATURDAY WITH WINTERY PRECIPITATION. MVFR CONDITIONS MAY CONTINUE
INTO SATURDAY NIGHT.
