JANUARY 2015 IN SOUTHWEST LOWER MICHIGAN WAS COLDER THAN NORMAL...
WITH NEAR TO ABOVE NORMAL SNOWFALL AND BELOW AVERAGE WATER
EQUIVALENT PRECIPITATION.

THE MONTH STARTED OUT ACTIVE AS A LARGE SCALE TROUGH SETTLED OVER
THE GREAT LAKES... PROVIDING MICHIGAN WITH VERY COLD AIR AT TIMES
AND FREQUENT ALBERTA CLIPPER WEATHER SYSTEMS WITH LAKE EFFECT SNOW.
MEASURABLE SNOW WAS RECORDED AT MUSKEGON AND GRAND RAPIDS FOR EACH
OF THE FIRST 10 DAYS EXCEPT FOR JANUARY 2ND. THE MOST SIGNIFICANT
SNOW EVENT OCCURRED THE EVENING AND NIGHT OF JANUARY 8TH WHEN LAKE
MICHIGAN ENHANCED A STRONG CLIPPER SYSTEM. MANY LOCATIONS WITHIN 40
MILES EAST OF LAKE MICHIGAN RECEIVED 8 TO 14 INCHES OF SNOW... AND
WIND GUSTS OF 40 TO 55 MPH NEAR THE LAKESHORE RESULTED IN
SUBSTANTIAL BLOWING AND DRIFTING. BOTH GRAND RAPIDS AND MUSKEGON SET
DAILY RECORD SNOWFALLS ON THE 8TH.

ARCTIC AIR WITH WELL BELOW NORMAL TEMPERATURES SETTLED INTO THE
GREAT LAKES FOR MOST OF THE PERIOD FROM THE 5TH THROUGH THE 14TH.
HIGH TEMPERATURES WERE FREQUENTLY IN THE TEENS. CALM AND CLEAR
CONDITIONS ON THE MORNINGS OF THE 13TH AND 14TH RESULTED IN LOW
TEMPERATURES BELOW ZERO ACROSS THE AREA. MUSKEGON TIED AND GRAND
RAPIDS BROKE THEIR RECORD LOW TEMPERATURES ON THE 13TH. GRAND RAPIDS
FELL TO 13 DEGREES BELOW ZERO THE MORNING OF THE 14TH... ITS COLDEST
TEMPERATURE SINCE 17 BELOW ZERO WAS OBSERVED ON THE 4TH OF FEBRUARY
1996.

FROM THE MIDDLE OF THE MONTH ONWARD... CONDITIONS WARMED UP AND
QUIETED DOWN. TEMPERATURES WERE GENERALLY NEAR TO ABOVE NORMAL.
LIGHT SNOW OCCURRED PERIODICALLY... BUT THERE WERE ONLY A FEW
OCCASIONS WITH MEASURABLE SNOW.
