LABOR DAY

 

 

LABOR DAY IS OBSERVED ON THE FIRST MONDAY IN SEPTEMBER.  LABOR DAY WAS FIRST CELEBRATED IN NEW YORK IN 1882 UNDER THE SPONSORSHIP OF THE CENTRAL LABOR UNION.  THE IDEA WAS SUGGESTED BY PETER J. MC GUIRE, OF THE KNIGHTS OF LABOR, THAT THE DAY BE SET ASIDE IN HONOR OF LABOR.

 

THE HIGHEST TEMPERATURE EVER RECORDED IN ROCHESTER ON LABOR DAY WAS ON SEPTEMBER 6, 1971 AND SEPT 3, 1973 WITH A HIGH TEMPERATURE OF 93 DEGREES.  ON THE OTHER SIDE OF THE SPECTRUM, CLEAR SKIES DURING THE EARLY MORNING HOURS OF SEPTEMBER 2, 1991 RESULTED IN A RECORD LOW TEMPERATURE OF 42 DEGREES.  NORMALLY, THE HIGH TEMPERATURE AVERAGED NEAR 77 DEGREES WHILE THE LOW AVERAGES ABOUT 56.

 

THERE IS ROUGHLY A 39 PERCENT CHANCE OF HAVING AT LEAST A TRACE OF PRECIPITATION AND ABOUT AN 11 PERCENT CHANCE OF A THUNDERSTORM. ON SEPTEMBER 1, 1980 AFTERNOON THUNDERSTORMS DROPPED 1.21 INCHES OF RAIN AT THE ROCHESTER AIRPORT‑‑THE MOST PRECIPITATION EVER RECORDED ON A LABOR DAY.

 

ON LABOR DAY IN 1944...SEPTEMBER 4TH...A MODERATE EARTHQUAKE OF 5.6 ON THE RICHTER SCALE WAS FELT AT 11:39 PM.  THE QUAKE WAS CENTERED AT MASSENA, BY THE ST. LAWRENCE RIVER. PERCEPTIBLE VIBRATIONS WERE FELT IN HOMES AND BUILDINGS.  LIGHT FURNITURE WAS DISPLACED AND DISHES RATTLED. THE SHOCK WAS FELT THROUGHOUT THE NORTHEASTERN UNITED STATES AND ONTARIO.  PROPERTY DAMAGE WAS REPORTED IN ONTARIO.
