REMARKS...

THE MONTH OF NOVEMBER SAW QUITE THE ROLLER-COASTER OF TEMPERATURES.
THE BEGINNING OF THE MONTH WAS MARKED BY REPEATED DAYS OF BELOW
AVERAGE TEMPERATURES. FOUR RECORD LOW TEMPERATURES WERE TIED OR
BROKEN THIS MONTH DURING THE SIX DAY SPAN OF NOV 5 THROUGH NOV 10
WITH THE COLDEST TEMPERATURE OF -9 OCCURING ON NOV 9. TOWARDS THE
END OF THE MONTH MOTHER NATURE FLIPPED THE THERMOSTAT WITH SEVERAL
DAYS OF ABOVE AVERAGE TEMPERATURES. TWO HIGH TEMPERATURE RECORDS
WERE TIED ON NOV 27 AND 29 WITH HIGH TEMPERATURES OF 48 AND 49
RESPECTIVELY.

SIMILAR TO THE SWING IN TEMPERATURES, GRAND FORKS EXPERIENCED A
SWING IN PRECIPITATION WITH MUCH OF THE MONTH`S PRECIPITATION
OCCURING DURING THE FIRST 8 DAYS OF THE MONTH. THE MONTH ENDED WITH
0.86 INCHES OF PRECIP, LESS THAN A TENTH OF AN INCH SHY OF AVERAGE.

MUCH OF THIS PRECIP FELL IN THE FORM OF SNOW DURING THE FIRST WEEK
OF THE MONTH. 10 INCHES OF SNOW FELL THIS MONTH, LEAVING A SNOW PACK
6 INCHES DEEP. AS MANY IN GRAND FORKS FOUND OUT, IT WOULD TAKE THE
REST OF THE MONTH AND THE ABOVE AVERAGE TEMPERATURES TO FINALLY MELT
THE SNOW PACK.

REMEMBER... THIS DATA IS PROVISIONAL AND SUBJECT TO CHANGE. THE
FINAL AND OFFICIAL RECORDS WILL BE AVAILABLE FROM THE NATIONAL
CENTERS FOR ENVIRONMENTAL INFORMATION (FORMERLY THE NATIONAL CLIMATE
DATA CENTER).
