TEMPERATURE WAS 29.4 DEGREES, 4.9 DEGREES ABOVE NORMAL.  THE AVERAGE
TEMPERATURE FROM THE 19TH TO THE 31ST WAS JUST 9.2 DEGREES. THIS
RANKED AS THE 4TH COLDEST AVERAGE TEMPERATURE ON RECORD FOR THIS
PERIOD TO END JANUARY. THE WARMEST TEMPERATURE FOR THE MONTH WAS 54
DEGREES ON THE 7TH AND THE COLDEST WAS 20 DEGREES BELOW ZERO ON THE
30TH AND 31ST. THIS WAS A 74 DEGREE DIFFERENCE BETWEEN THE MONTHLY
HIGH AND LOW TEMPERATURE.

THE AVERAGE MONTHLY TEMPERATURE FOR ALL OF JANUARY 2019 ENDED UP
BEING 21.0 DEGREES, 3.4 DEGREES BELOW NORMAL. THIS RANKED AS THE
31ST COLDEST JANUARY ON RECORD.

PRECIPITATION FOR JANUARY WAS 1.78 INCHES, 0.51 INCHES BELOW NORMAL.
THIS RANKED AS THE 50TH DRIEST JANUARY ON RECORD. DESPITE THE BELOW
NORMAL PRECIPITATION, SNOWFALL WAS ABOVE NORMAL. TOTAL SNOWFALL WAS
23.9 INCHES, 3.3 INCHES ABOVE NORMAL. THIS RANKED AS THE 31ST
SNOWIEST JANUARY ON RECORD.

SEVERAL DAILY RECORDS WERE SET IN JANUARY. A DAILY RECORD SNOWFALL
OF 6.7 INCHES OCCURRED ON THE 28TH. RECORD LOW TEMPERATURES WERE
BROKE ON THE 30TH AND 31ST WITH A LOW OF 20 DEGREES BELOW ZERO ON
