JANUARY 2016 TEMPERATURES IN THE SOUTHWEST QUARTER OF LOWER MICHIGAN AVERAGED 1
TO 2 DEGREES ABOVE NORMAL. SNOWFALL AND PRECIPITATION WERE ABOVE NORMAL IN
MUSKEGON... NEAR NORMAL IN GRAND RAPIDS... AND BELOW NORMAL IN LANSING.

THERE WERE SEVERAL TEMPERATURE SWINGS BETWEEN COLD AND MILD DURING THE MONTH...
BUT OVERALL THERE WERE VERY FEW EXTREMES. LANSING SET A RECORD WARM LOW
TEMPERATURE ON THE 9TH. A FEW DAYS FEATURED TEMPERATURES DIPPING BELOW 10
DEGREES AND HIGHS REMAINING IN THE TEENS. THE END OF THE MONTH WAS QUITE MILD
WITH TEMPERATURES IN THE 40S TO AROUND 50.

FOLLOWING A RECORD WARM DECEMBER... LAKE MICHIGAN WATER TEMPERATURES IN THE LOW
40S IN EARLY TO MID JANUARY AFFORDED THE ATMOSPHERE OPPORTUNITIES TO PRODUCE
SIGNIFICANT LAKE EFFECT SNOW WHEN POLAR AIR MASSES MOVED IN FROM THE NORTHWEST.
HEAVY LAKE EFFECT SNOW DID INDEED OCCUR ON A COUPLE OCCASIONS AND MAINLY
FAVORED THE NORTHWEST AND SOUTHWEST WIND SNOW BELTS. MUSKEGON RECEIVED OVER 20
INCHES OF SNOW BETWEEN THE 9TH AND 13TH FROM BOTH LAKE EFFECT AND LAKE ENHANCED
LOW PRESSURE SYSTEMS. ANOTHER FOOT OF SNOW FELL BETWEEN THE 17TH AND 20TH.
VARIOUS LOW PRESSURE SYSTEMS PRODUCED RAIN AND OCCASIONAL ACCUMULATIONS OF SNOW
FOR ALL AREAS... THOUGH NO MEMORABLE WINTER STORM OCCURRED.
