A NEAR NORMAL JANUARY...

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 73 DEGREES AND SEPARATED BY JUST 8 DAYS. THE LOWEST
TEMPERATURE OF THE MONTH WAS 15 DEGREES BELOW ZERO ON THE 2ND AND
THE WARMEST TEMPERATURE WAS 58 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 23.7 DEGREES, 0.7 DEGREES BELOW
NORMAL. THIS RANKED AS JUST THE 46TH COLDEST JANUARY ON RECORD AND
TIED WITH 1903 AND 1917. THERE WERE 5 DAYS WITH TEMPERATURES BELOW
ZERO.

PRECIPITATION FOR THE MONTH WAS 1.93 INCHES WHICH WAS 0.36 INCHES
BELOW NORMAL. THIS RANKED AS THE 56TH DRIEST JANUARY ON RECORD.

DESPITE BELOW NORMAL PRECIPITATION, SNOWFALL WAS SLIGHTLY ABOVE
NORMAL. A TOTAL OF 22.0 INCHES FELL WHICH WAS 1.4 INCHES ABOVE
NORMAL. THIS RANKED AS THE 37TH SNOWIEST JANUARY ON RECORD.
