MAY 2016 ENDED UP SLIGHTLY WARMER THAN NORMAL... THOUGH FEATURED
HINTS OF WINTER AND SUMMER WEATHER NOT MORE THAN WEEKS APART.
PRECIPITATION TOTALS WERE LESS THAN NORMAL. SCATTERED THUNDERSTORMS
OCCURRED AT TIMES BUT ALMOST ENTIRELY REMAINED BELOW SEVERE LEVELS.

THE FIRST TWO WEEKS OF THE MONTH BROUGHT VARIABLE TEMPERATURES AS
CAN BE EXPECTED IN LATE SPRING. HIGH TEMPERATURES RANGED BETWEEN THE
50S AND 70S... AND LOW TEMPERATURES DIPPED BELOW FREEZING IN SPOTS.

A SHARP COOL DOWN OCCURRED ON THE 14TH AND 15TH... WITH RECORD COLD
HIGH TEMPERATURES BEING TIED AT GRAND RAPIDS AND MUSKEGON ON THE
14TH. HIGH TEMPERATURES STRUGGLED TO REACH 50 DEGREES. SCATTERED
SNOW SHOWERS DEVELOPED THE MORNING OF THE 15TH. LIGHT ACCUMULATIONS
GENERALLY LESS THAN A HALF INCH WERE MEASURED IN A NUMBER OF
LOCATIONS. GRAND RAPIDS AND LANSING OFFICIALLY RECORDED A TRACE OF
SNOW... TYING OR EVEN BREAKING DAILY RECORDS.

TEMPERATURES QUICKLY REBOUNDED TO NEAR NORMAL AFTER THE LAST GASP OF
WINTER... AND THEN WARMED TO ABOVE NORMAL FOR THE FINAL THIRD OF THE
MONTH. HIGH TEMPERATURES IN THE 80S AND LOW TEMPERATURES IN THE 60S
WERE COMMON FOR SEVERAL DAYS. EAST WINDS KEEPING LAKE MICHIGAN
MODIFIED AIR AT BAY ALLOWED MUSKEGON TO REACH A RECORD HIGH ON MAY
31ST.
