JANUARY AVERAGED ABOVE NORMAL FOR BOTH THE TEMPERATURE AND
PRECIPITATION. SNOWFALL WAS BELOW NORMAL OVER MOST OF THE AREA.

THERE WAS CONSIDERABLE VARIABILITY WITH TEMPERATURES RUNNING WELL
ABOVE NORMAL IN BOTH THE SECOND WEEK AND TOWARD THE END OF THE
MONTH. DURING THE SECOND WEEK OF JANUARY TEMPERATURES WERE MORE
THAN 20 DEGREES ABOVE NORMAL FOR SEVERAL DAYS. MEANWHILE DURING THE
THIRD WEEK...INTO THE START OF THE FOURTH WEEK OF JANUARY...
TEMPERATURES WERE AS MUCH AS 20 DEGREES BELOW NORMAL. THAT WAS THE
COLDEST WEEK SINCE THE SECOND WEEK IN JANUARY OF 2009. MOST LOCATINS
HAD THREE TO FOUR DAYS WITH HIGHS BELOW 20. MOST LOCATIONS HAD AT
LEAST ONE DAY WITH A LOW BELOW ZERO.

PRECIPITATION WAS WELL ABOVE NORMAL...WITH SOME LOCATIONS NORTH OF
I-96 HAVING AROUND 200 PERCENT OF THE NORMAL PRECIPITATION. MOST OF
THE PRECIPITATION FELL BETWEEN THE 9TH AND 13TH AND THEN AGAIN
DURING THE LAST 10 DAYS OF THE MONTH. RECORD OR NEAR RECORD RAINFALL
OCCURRED ON THE 29TH. MUSKEGON HAD THE SECOND WETTEST JANUARY DAY ON
RECORD WITH 2.48 INCHES... THE WETTEST DAY WAS JANUARY 3RD 1897 WITH
4.90 INCHES OF RAIN. MOST OF THE AREA HAD BETWEEN 1 AND 3 INCHES OF
RAIN. THAT CAUSED CONSIDERABLE FLOODING DUE TO THE COMBINATION
HEAVY RAIN... SNOW MELT AND ICE JAM FLOODING.

SNOWFALL WAS FROM 50 TO 75 PERCENT OF NORMAL OVER THE CENTRAL AND
EASTERN SECTIONS AND 75 TO NEAR 100 PERCENT NORTH OF HOLLAND AND
WEST OF US-131. MOST OF THE SNOW THAT FELL OVER SOUTHWEST LOWER
MICHIGAN DURING JANUARY 2013 WAS EITHER LAKE ENHANCED OR LAKE
EFFECT. LITTLE IN THE WAY OF SYNOTIC SNOWFALL OCCURED. NEARLY ALL OF
THE SNOW FELL DURING THE THIRD AND FOURTH WEEK OF THE MONTH. MANY
LOCATIONS WEST OF US-131 AND NORTH OF I-94 HAD ONE TO TWO FEET OF
SNOW DURING THIS TIME. ANOTHER SYSTEM ON THE LAST DAY OF THE MONTH
BROUGHT FROM 3 TO 9 INCHES TO AREAS SOUTH AND WEST OF GRAND RAPIDS.
