...NEAR NORMAL TEMPERATURES BUT BELOW NORMAL PRECIPITATION...

JANUARY WAS A MONTH OF EXTREMES AND FLUCTUATIONS IN THE WEATHER AS
VERY COLD AND WARM TEMPERATURES WERE EXPERIENCED AT TIMES. THE MONTH
BEGAN WITH BITTERLY COLD ARCTIC AIR AND SUB ZERO TEMPERATURES ACROSS
THE REGION MAKING FOR ONE OF THE COLDEST NEW YEAR DAYS IN HISTORY.
THE COLD AIR SUBSIDED BRIEFLY BUT CAME BACK WITH MORE SUB ZERO AIR
DURING THE SECOND AND THIRD WEEKS OF THE MONTH.

THE DIFFERENCE BETWEEN THE WARMEST AND COLDEST TEMPERATURES WAS A
WHOPPING 72 DEGREES AND SEPARATED BY JUST 8 DAYS. THE LOWEST
TEMPERATURE OF THE MONTH WAS 13 DEGREES BELOW ZERO ON THE 2ND AND
THE WARMEST TEMPERATURE WAS 59 DEGREES ON THE 11TH. BOTH OF THESE
TEMPERATURES WERE DAILY RECORDS ON THEIR RESPECTIVE DATES.

DESPITE THE OVERALL FEELING THAT JANUARY WAS COLD, THERE WERE
ACTUALLY MORE DAYS WITH ABOVE NORMAL TEMPERATURES THAN BELOW NORMAL.
HOWEVER, MOST BELOW NORMAL DAYS WERE WELL BELOW NORMAL AND AS MUCH
AS 20 TO 30 DEGREES BELOW NORMAL. THIS WAS DUE TO BITTERLY COLD
ARCTIC AIR THAT INTRUDED DURING TWO SEPARATE PERIODS DURING THE
FIRST HALF OF THE MONTH.  THE PERIOD FROM JANUARY 19TH THROUGH THE
31ST DID NOT HAVE A DAY WITH A BELOW NORMAL AVERAGE TEMPERATURE.
THIS MILD END TO THE MONTH HELPED EVEN OUT THE COLD STRETCHES AND
LED TO A NEAR NORMAL AVERAGE MONTHLY TEMPERATURE.

THE AVERAGE MONTHLY TEMPERATURE WAS 25.2 DEGREES, 0.3 DEGREES ABOVE
NORMAL. THIS RANKED AS THE 65TH WARMEST JANUARY ON RECORD AND TIED
WITH 1927, 1956 AND 2001. THERE WERE 7 DAYS WITH TEMPERATURES BELOW
ZERO. THERE WERE ONLY 11 OTHER JANUARY MONTHS WITH MORE BELOW ZERO
DAYS.

PRECIPITATION FOR THE MONTH WAS 1.25 INCHES WHICH WAS 1.01 INCHES
BELOW NORMAL. THIS RANKED AS THE 27TH DRIEST JANUARY ON RECORD, TIED
WITH THE YEAR 2000.

SNOWFALL WAS ALSO BELOW NORMAL. A TOTAL OF 7.2 INCHES FELL WHICH WAS
2.9 INCHES BELOW NORMAL. THIS RANKED AS THE 55TH LEAST SNOWIEST
JANUARY ON RECORD.
