The Blizzard of 1978 -- CVG

Go Back

JANUARY 25TH - 27TH OF 1998 MARKS THE 20TH ANNIVERSARY OF THE BLIZZARD
OF 1978.

ON JANUARY 25TH - 27TH OF 1978...A LARGE STORM SYSTEM RACED ACROSS THE
OHIO  VALLEY REGION  AND TRACKED ACROSS  CENTRAL OHIO.   THIS DEEP LOW
PRESSURE  SYSTEM PRODUCED  PRESSURE READINGS  AROUND  28.50 INCHES  OF
MERCURY ACROSS  MUCH OF  THE REGION...COLUMBUS  RECORDED A RECORD  LOW
PRESSURE  OF 28.47  INCHES  OF  MERCURY ON  JANUARY  26TH.   CLEVELAND
AIRPORT HAD A  READING OF 28.28 INCHES.  NO READING THIS LOW  HAD EVER
BEEN  REACHED ON THE UNITED STATES MAINLAND BEFORE THIS TIME EXCEPT IN
HURRICANES.

ACROSS WESTERN AND  SOUTHWESTERN SECTIONS OF OHIO...THIS  STORM SYSTEM
WAS A  MAJOR PRODUCER OF  SNOW WITH DAYTON RECEIVING  ALMOST 13 INCHES
AND CINCINNATI NEARLY 7 INCHES DURING THIS TIME PERIOD.  WHILE  ACROSS
CENTRAL OHIO...THE  PRECIPITATION FROM  THIS STORM  BEGAN AS RAIN  AND
CHANGED OVER  TO SNOW...WHICH RESULTED  IN LESSER AMOUNTS  ACROSS THIS
REGION.  WIND  GUSTS ASSOCIATED WITH THE  BLIZZARD WERE AS HIGH  AS 69
MPH AT THE  PORT COLUMBUS AIRPORT.   THE RESULT OF THESE  STRONG WINDS
WAS THE SIGNIFICANT  BLOWING AND DRIFTING  OF SNOW ACROSS MUCH  OF THE
REGION.

FOR CINCINNATI IN PARTICULAR...JANUARY 1978 WILL GO DOWN IN THE RECORD
BOOKS AS A COLD AND SNOWY MONTH WITH MANY MONTHLY AND SEASONAL RECORDS
BROKEN.  THE MONTHLY SNOWFALL FOR JANUARY 1978 WAS 31.5 INCHES...WHICH
IS THE HIGHEST AMOUNT OF  SNOW FOR ANY MONTH.  THE  GREATEST SNOW FALL
FOR A SEASON WAS ALSO BROKEN WITH THE 1977-1978 SEASONAL TOTAL OF 53.9
INCHES.

THE MAXIMUM  SNOW DEPTH AT CINCINNATI UP TO  THAT TIME WAS JUST BEFORE
THE BLIZZARD  WITH 14 INCHES  ON JANUARY 20TH AND  21ST OF 1978.   THE
MOST  CONSECUTIVE DAYS  WITH ONE INCH  OR MORE  OF SNOW ON  THE GROUND
OCCURRED  FOR 63 DAYS  FROM JANUARY 8  THROUGH MARCH 11  1978.  DURING
THAT WINTER...FIVE OR MORE INCHES WERE ON  THE GROUND FOR 43 DAYS FROM
JANUARY 13 THROUGH FEBRUARY 24, AND  10 INCHES OR MORE INCHES WERE  ON
THE GROUND FOR 10 DAYS FROM JANUARY 16 THROUGH JANUARY 25.

THE WINTER  OF 1976  - 1977  HAD 39  CONSECUTIVE DAYS OF  ONE OR  MORE
INCHES ON THE GROUND FROM JANUARY 4 THROUGH FEBRUARY 11 1977.

OTHER EXTENDED PERIODS OF AN INCH OR MORE OF SNOW COVER WERE:

   29 DAYS...JANUARY 11 1918 - FEBRUARY 8 1918
   27 DAYS...DECEMBER 22 1969 - JANUARY 17 1970
