RECORD... THIS FEBRUARY HAD THE 8TH MOST SNOW FOR ALL FEBRUARYS ON
RECORD WITH 29.0 INCHES.

&&

THE UNUSUALLY COLD AND SNOWY JANUARY WEATHER CARRIED RIGHT OVER INTO
FEBRUARY. FEBRUARY 2014 WAS MUCH COLDER AND SNOWIER THAN NORMAL
ACROSS SOUTHWEST LOWER MICHIGAN. IN FACT... THE DEEPEST SNOW DEPTH
IN FEBRUARY ON RECORD FOR GRAND RAPIDS WAS MEASURED THIS YEAR.

AVERAGE TEMPERATURES IN FEBRUARY WERE IN THE MID TO UPPER TEENS...
AROUND 9 DEGREES COLDER THAN NORMAL FOR THE MONTH. AN AVERAGE
DEPARTURE OF 9 DEGREES FOR AN ENTIRE MONTH IS VERY SIGNIFICANT.
POLAR AIR FREQUENTLY STREAMED IN FROM CANADA AND RESULTED IN THE
11TH COLDEST FEBRUARY ON RECORD IN GRAND RAPIDS AND MUSKEGON. ONLY 4
DAYS IN FEBRUARY SAW TEMPERATURES RISE ABOVE FREEZING. THIS STRETCH
OF WARMER WEATHER OCCURRED FEBRUARY 18TH THROUGH THE 21ST...WHEN
HIGH TEMPERATURES SOARED INTO THE 40S. HOWEVER... BITTERLY COLD AIR
RETURNED DURING THE LAST FEW DAYS OF THE MONTH. RECORD LOW
TEMPERATURES WERE OBSERVED ON THE 28TH IN GRAND RAPIDS AND MUSKEGON.
GRAND RAPIDS DROPPED TO -12 AND MUSKEGON DROPPED TO -7. MANY
LOCATIONS ACROSS WEST MICHIGAN DROPPED TO 10 TO 20 DEGREES BELOW
ZERO ON THE MORNING OF THE 28TH.

FEBRUARY 2014 WAS ALSO MUCH SNOWIER THAN NORMAL. SOUTHWEST LOWER
MICHIGAN RECEIVED 3 TO 6 INCHES OF SNOW ON THE 4TH AND 5TH OF
FEBRUARY FROM A STORM THAT PASSED TO THE SOUTH OF MICHIGAN. THE SNOW
CAUSED NUMEROUS ACCIDENTS AND RESULTED IN SOME HIGHWAYS BEING
CLOSED... INCLUDING I-94 AND US-131. UNFORTUNATELY... THESE WERE
JUST TWO OF SEVERAL DAYS IN FEBRUARY FEATURING HAZARDOUS DRIVING
CONDITIONS. ON FEBRUARY 17TH...AN AREA OF LOW PRESSURE TRACKED
THROUGH NORTHERN INDIANA AND RESULTED IN A LARGE SWATH OF 4 TO 7
INCHES OF SNOW ACROSS SOUTHWEST LOWER MICHIGAN... WITH LOCALLY
HIGHER AMOUNTS IN CENTRAL LOWER MICHIGAN. THIS WINTER SYSTEM PUSHED
THE SNOW DEPTH IN GRAND RAPIDS UP TO 24 INCHES... A NEW RECORD DEPTH
FOR THE MONTH OF FEBRUARY. THIS IS THE 2ND DEEPEST SNOW DEPTH ALL
TIME FOR GRAND RAPIDS... SECOND ONLY TO 27 INCHES IN JANUARY 1978
AFTER THE BLIZZARD OF 1978.

ONE OF THE MORE SIGNIFICANT EVENTS DURING FEBRUARY OCCURRED DURING
THE BRIEF WARMUP. ON THE 20TH AND 21ST... MULTIPLE HAZARDS IMPACTED
SOUTHWEST LOWER MICHIGAN. THE 20TH FEATURED MIXED PRECIPITATION
ALONG WITH HEAVIER RAINFALL IN THE AFTERNOON TOWARD JACKSON...
RESULTING IN LOCALIZED URBAN FLOODING. THUNDERSNOW WAS ALSO REPORTED
IN SOUTHERN LOWER MICHIGAN. BIGGER IMPACTS WERE REALIZED ON THE
21ST. MODERATE TO HEAVY SNOWFALL AND WINDS GUSTING TO 45-60 MPH
CREATED BLIZZARD LIKE CONDITIONS IN SOME AREAS. SIGNIFICANTLY
REDUCED VISIBILITIES AND STRONG WINDS RESULTED IN MULTIPLE TRAFFIC
ACCIDENTS AND A CLOSURE OF US-127 IN ISABELLA COUNTY.

YET ANOTHER BLAST OF ARCTIC AIR... STRONG WINDS AND LAKE EFFECT
SNOW RESULTED IN BLIZZARD LIKE CONDITIONS ON THE 27TH OF FEBRUARY.
BLOWING SNOW RESULTED IN VERY POOR CONDITIONS FOR THE MORNING
COMMUTE. GRAND RAPIDS RECEIVED 3.9 INCHES OF SNOW... WHICH MAKES THE
WINTER OF 2013-2014 THE SECOND SNOWIEST WINTER ON RECORD.
