MARCH 2015 WAS COOLER THAN NORMAL... WITH PRECIPITATION AND SNOWFALL
VALUES BELOW NORMAL.

THE FIRST WEEK OF MARCH 2015 SAW TEMPERATURES BELOW NORMAL WITH
FREEZING RAIN... SLEET... SNOW AND RAIN. AFTER A LITTLE LAKE EFFECT
SNOW... TEMPERATURES ROSE TO ABOVE NORMAL LEVELS FOR THE NEXT WEEK
AND A HALF WITH THE WEATHER MAKERS PASSING BY THE AREA. AS THE DRY
WEATHER CONTINUED FOR MOST OF THE NEXT WEEK... TEMPERATURES AGAIN
FELL BELOW NORMAL AS ARCTIC AIR AGAIN PUSHED IN. THIS ARCTIC
INTRUSION BROUGHT BACK FREEZING RAIN... SLEET... SNOW AND RAIN TO
END THE MONTH.

THE AVERAGE TEMPERATURES FOR MARCH WERE AROUND TO A LITTLE BELOW
FREEZING. AT THE MAJOR CLIMATE SITES OF GRAND RAPIDS... LANSING AND
MUSKEGON... THE VALUES WERE ALL BETWEEN 32 AND 33 DEGREES. THESE
TEMPERATURES ARE 2 TO 3 DEGREES COOLER THAN NORMAL. THERE WERE FEW
DAILY RECORD TEMPERATURES IN MARCH 2015.

PRECIPITATION TOTALS VARIED FROM HALF AN INCH UP TO AN INCH AND A
HALF ACROSS SOUTHWEST LOWER MICHIGAN FOR MARCH 2015. THIS WAS 1 TO 2
INCHES BELOW NORMAL... WITH THE GREATEST SHORTFALLS ACROSS THE
SOUTH. THE 1.05 INCHES OF PRECIPITATION RECORDED IN GRAND RAPIDS FOR
MARCH 2015 WAS THE 9TH DRIEST MARCH ON RECORD... WHILE THE 0.74
INCHES IN LANSING WAS THE 7TH DRIEST ON RECORD. MUSKEGON WAS NOT A
TOP TEN FINISHER.

SNOWFALL IN MARCH 2015 RANGED FROM 2 TO 5 INCHES ACROSS MUCH OF
LOWER MICHIGAN. THIS WAS ABOUT HALF OF NORMAL SNOW TOTALS WITH
NORTHERN AREAS SEEING THE GREATEST DEFICIT.

THE MAIN WEATHER DURING MARCH 2015 WAS NON THUNDERSTORM WINDS OF
OVER 40 MPH A COUPLE TIMES DURING THE MONTH... AND SOME MINOR ICE
ACCUMULATIONS NEAR THE BEGINNING AND AGAIN NEAR THE END OF THE
MONTH.
