        STRONG WINDS BLEW SNOW ACROSS THE RUNWAYS AT CENTENNIAL
        AIRPORT...WHICH GLAZED OVER AND FORMED AREAS OF ICE.  TWO

      IN 1956...WEST-NORTHWEST WINDS GUSTED TO 52 MPH AT STAPLETON
        AIRPORT.
      IN 1996...THE FIRST SNOW STORM OF THE NEW YEAR DUMPED MORE

        ON THE 2ND.  SOUTHWEST WINDS SUSTAINED TO 60 MPH WITH GUSTS
        AS HIGH AS 66 MPH WARMED THE TEMPERATURE TO A HIGH OF 55
        DEGREES ON THE 1ST.  NORTHWEST WINDS SUSTAINED TO 54 MPH
        WITH GUSTS TO 60 MPH RESULTED IN SNOWFALL OF 0.3 INCH AND
        A HIGH TEMPERATURE OF ONLY 31 DEGREES ON THE 2ND.
1-5   IN 1940...THE FIRST DAYS OF THE MONTH WERE CHARACTERIZED BY A
        MIXTURE OF DRIZZLE...LIGHT SNOW...AND FOG.  FOG OCCURRED ON
        EACH DAY.  ON THE 4TH AND 5TH CONSIDERABLE GLAZING RESULTED
        FROM FREEZING DRIZZLE.  ALL OBJECTS WERE COATED WITH A
        GLAZE ON THE WINDWARD SIDE.  THIS RESULTED IN VERY SLIPPERY
        STREETS...WHICH CAUSED SEVERAL MINOR TRAFFIC ACCIDENTS.  THE
        GLAZE WAS NOT HEAVY ENOUGH TO DAMAGE WIRES AND CABLES.
