The episode as NWS RLX wrote it up.
Another major rain event occurred from late on the 9th into the evening hours of the 10th. Rain amounts of 1 to 2 inches were common. Including this episode, the accumulative affects of 5 significant rain events since February 21st, caused the Ohio River to flood. The crest along the Ohio River was mostly 2 to 6 feet above the assigned flood stages. The crest occurred late on the 12th into the morning hours of the 13th. Along many reaches, it was the highest stage on the Ohio River since 2005. Some of the flood gates were installed in the Ironton floodwall, forcing a school to be canceled for a few days.
The crest of 49 feet at Pomeroy did allow water to reach the businesses along Main Street. Water was about 6 inches to a foot inside the structures. However, damage was minimal. Inventory and personal property was moved to higher levels well in advance of the flood. The Pomeroy police chief said, the community knew what they needed to do, they knew what was expected, and they stuck together, and that's what separates us from other people.
In Lawrence County, about 20 properties along the river had minor water problems. This was either water reaching around their homes, or into their garages and outbuildings.
The other most significant impact was road closures along the entire reach of the river in southeast Ohio. This caused motorists to take alternate routes for a few days. In the wake of the high water, a few roads suffered slips from the saturated ground. Many of the flood prone parks and recreational areas along the river were also flooded, including some of their outbuildings.
The unique feature about this flood, was the fact that there was very little headwater river or small small flooding in southeast Ohio. Leading into the Ohio River flood, only some minor stream flooding occurred along portions of some of the larger creeks, such as Raccoon Creek and the Little Muskingum River.
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 Charleston, WV wrote its last area forecast discussion before the first event at Mar 10, 4:36 AM EST, 1 hour 24 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
436 AM EST THU MAR 10 2011
.SYNOPSIS...
COLD FRONT MOVES THROUGH THE AREA TODAY...WITH LOW PRESSURE MOVING
UP ALONG FRONT LATER TODAY AND TONIGHT. ANOTHER COLD FRONT
CROSSES LATE SATURDAY. HIGH PRESSURE ARRIVES LATE SUNDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
FRONT ASSOCIATED WITH LARGE...COMPLEX LOW PRESSURE SYSTEM JUST
ENTERING CWA FROM THE W...AS DEPICTED BY BACK EDGE OF RAIN BAND.
UPPER LEVEL LOW TRIES TO CLOSE OFF TO THE S OF THE AREA TODAY AS ITS
PARENT TROUGH MOVES E AND TAKES ON A NEGATIVE TILT. SURFACE LOW
SHOULD REFORM ALONG FRONT S OF THE AREA IN RESPONSE.
EXPECT THE RAIN BAND TO MOVE SLOWLY NE THROUGH FORECAST AREA THIS
MORNING...FOLLOWED BY NEW PRECIPITATION DEVELOPMENT FROM THE S.
THIS RAIN SHOULD THEN SPREAD QUICKLY N IN RESPONSE TO THE UPPER
FORCING AND DEVELOPING SURFACE LOW. USED WRFAR5/NAM12/HPC FOR QPF
FOR QPF AS THESE MODELS DEPICT THE WAVE BUT INCLUDE A LITTLE SPREAD
FOR UNCERTAINTY. THIS BRINGS RAINFALL TOTALS OF AROUND A HALF AN
INCH...JUST ENOUGH TO NOT JUSTIFY CANCELING THE FLOOD
WATCH...ESPECIALLY WITH SOME RIVER ISSUES IN OHIO OUTSIDE THE OHIO
RIVER WHICH...OF COURSE...BECOMES QUITE PROBLEMATIC LATER. SEE
HYDRO SECTION OF THIS AFD.
AS THE LOW MOVES N LATER TODAY INTO TONIGHT...AND THE FRONT MOVES
E...COLDER AIR WILL OVERSPREAD THE AREA WHILE FORCING AND DEEP
MOISTURE REMAIN. THIS WILL LEAD TO A CHANGEOVER TO SNOW AND
OVERNIGHT ACCUMULATIONS.
WITH THE ADJMET LOOKING RATHER REASONABLE FOR TEMPERATURES GIVEN LOW
LEVEL TEMPERATURE FIELDS AND MODEL SOUNDINGS...TEMPERATURES DO NOT
FALL BELOW FREEZING UNTIL TOWARD 00Z IN THE MOUNTAINS...AND AFTER 2
OR 3 Z IN THE LOWLANDS...SO DO NOT EXPECT ACCUMULATING SNOW UNTIL
THEN.
USED A NAM12/HPC BLEND FOR QPF AND...EVEN WITH OROGRAPHIC EFFECTS
ADDED...SNOW AMOUNTS IN MOUNTAINS DID NOT LOOK VERY IMPRESSIVE AS
THAT AREA AS IT WILL HAVE ONE OR PERHAPS TWO DRY SLOTS
TRAVERSING...LIMITING DEEPER MOISTURE AT TIMES. A HARD HIT AREA
FOR SNOW APPEARS TO BE E-CENTRAL OHIO WHERE THE DEFORMATION ZONE
SETS UP. HAVE THUS WENT ONLY WITH A WINTER WEATHER ADVISORY FOR THE
NORTHERN MOUNTAINS FOR TONIGHT AND FRI...AND ALSO ISSUED ONE FOR E
CENTRAL OHIO FOR TONIGHT AND FRI MORNING.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
UNSETTLED WEATHER CONTINUES IN THE SHORT TERM AS A SURFACE LOW
PRESSURE REMAINS TO OUR NORTHEAST...AND UPPER LOW REMAINS OVER THE
REGION. AS A RESULT...EXPECTING SNOW CWA WIDE EARLY
FRIDAY...TRANSITIONING TO A RAIN SNOW MIX...THEN RAIN OVER MUCH OF
THE LOWLANDS...WITH SNOW REMAINING OVER MUCH OF THE HIGHER TERRAIN
THROUGHOUT THE DAY. ADDITIONAL LIGHT ACCUMULATIONS ARE EXPECTED IN
THE LOWLANDS FRIDAY MORNING...WITH A FEW INCHES STILL POSSIBLE IN
THE HIGHER TERRAIN IN THE CONTINUED UPSLOPE FLOW.
KEPT THE WEATHER UNSETTLED UNTIL FRIDAY NIGHT/EARLY SATURDAY WHEN
HIGH PRESSURE BRIEFLY BUILDS IN BEHIND THE DEPARTING LOW.
HOWEVER...ANOTHER LOW PRESSURE SYSTEM WILL DROP OUT OF THE UPPER
MIDWEST SATURDAY...BRINGING UNSETTLED WEATHER TO THE REGION ONCE
AGAIN FOR THE REMAINING PART OF THE SHORT TERM PERIOD.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
LOW CONFIDENCE FCST CONTINUES THIS GO AROUND IN THE EXTENDED AS
BLOCKING SETS UP IN HIGH LATITUDES. ELECTED TO STAY CLOSE TO HPC
GUIDANCE GIVEN MODEL DISCREPANCY REGARDING TRACK OF UPR LEVEL SYSTEM
SAT/SAT NIGHT. THIS KEEPS BEST CHANCE OF LIGHT PRECIPITATION
CONFINED ACROSS THE NORTH AND THE MTNS...MAINLY IN THE FORM OF -RA
EXCEPT ACROSS THE NORTHERN MTNS.
MODELS DISCREPANCIES CONTINUE FOR NEXT SYSTEM SLATED FOR EARLY NEXT
WEEK...TRIED TO STAY CLOSE TO HPC SOLUTION WITH A SFC LOW SCOOTING
ACROSS THE SOUTHERN STATES. THIS WILL BRING ANOTHER SHOT OF
PRECIPITATION IN FOR EARLY NEXT WEEK WITH THREAT OF ACCUMULATING
SNOW ACROSS MTNS.
&&
.AVIATION /09Z THURSDAY THROUGH MONDAY/...
WET LOW PRESSURE SYSTEM HAVING HIGH AVIATION IMPACT ACROSS THE
REGION OVERNIGHT THROUGH THURSDAY NIGHT. IFR OR WORSE CONDITIONS
EXPECTED OVERNIGHT IN KBKW AND GREENBRIER VALLEY AREAS...THANKS TO
MOIST SOUTHEAST UPSLOPE AHEAD OF INBOUND FRONT. ALSO...STRONG
SOUTH-SOUTHEAST JET ALONG THE APPALACHIAN RIDGETOPS THROUGH
11Z...WITH GUSTS THERE OF 30-40 KTS. GENERALLY MVFR TO EVEN VFR
ELSEWHERE IN THE LOWLANDS AHEAD OF THE FRONT...BUT SLOWING FRONT
PROGRESSES WEST TO EAST 09Z TO 21Z THURSDAY. FRONT TO BE ACCOMPANIED
BY LINE OF BRIEF IFR VIS GUSTY SHOWERS...AND IFR CIGS IN ITS WAKE AT
LEAST FOR A TIME. ANY SLIGHT IMPROVEMENT BACK INTO MVFR DURING THE
DAY...WILL BE REPLACED BY IFR OR WORSE CIGS AREAWIDE ESPECIALLY
AFTER 00Z FRIDAY...AS RAIN MIXES WITH AND THEN CHANGES OVER TO SNOW.
GUSTY SE FLOW WILL DIMINISH EARLY THURSDAY MORNING AS THE FRONT
APPROACHES...AND THEN BECOME STRONG AND GUSTY FROM THE W FROM WEST
TO EAST ACROSS THE AREA LATE THURSDAY MORNING INTO THURSDAY
AFTERNOON. MODERATE SW FLOW ALOFT WILL BECOME LIGHT SE EARLY
THURSDAY MORNING...AND THEN MODERATE NW THURSDAY AFTERNOON AND NIGHT.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z FRIDAY...
FORECAST CONFIDENCE: MEDIUM TO LOW
ALTERNATE SCENARIOS: UPPER DISTURBANCE ALONG BACK SIDE OF FRONT WILL
CAUSE REDEVELOPMENT OF RAIN 12Z-18Z...AND THIS POTENTIALLY MAY CAUSE
IFR CONDITIONS TO PERSIST...INSTEAD OF IMPROVEMENT TO MVFR.
