                             MARCH FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT A GREATER
THAN CLIMATOLOGICAL CHANCE OF ABOVE NORMAL MONTHLY PRECIPITATION
ACROSS ALL OF UPPER MICHIGAN IN MARCH 2017.

                           MARCH CLIMATOLOGY

AS THE SUN CONTINUES ITS MARCH NORTHWARD DURING THE THIRD MONTH OF
THE YEAR...DAYLIGHT AND AVERAGE TEMPERATURES INCREASE STEADILY. THE
POSSIBLE SUNSHINE INCREASES FROM 666 MINUTES ON 3/1 TO 765 MINUTES
ON 3/31. ON 3/1...NORMAL MAXIMUM AND MINIMUM TEMPERATURES AT THE
MARQUETTE NWS ARE 30 AND 8...BUT REBOUND TO 40 AND 20 ON 3/31.
MONTHLY AVERAGE TEMPERATURES THROUGHOUT UPPER MICHIGAN ARE 8 TO 11
DEGREES HIGHER IN MARCH THAN FEBRUARY. REMEMBER TO TURN YOUR CLOCKS
AHEAD ONE HOUR AT 2 AM EST ON SUNDAY 3/12 AS MOST OF THE UNITED
STATES TRANSITIONS FROM STANDARD TIME TO DAYLIGHT SAVINGS TIME.
SPRING ARRIVES IN THE NORTHERN HEMISPHERE THIS YEAR ON 3/20 AT 6:29
AM EDT.

SPRING OFTEN TEASES UPPER MICHIGAN RESIDENTS DURING MARCH WITH
RECORD HIGH TEMPERATURES REACHING WELL INTO THE 60S AND 70S COMMON
BY MONTH`S END. BUT IN MARCH 2012...UNPRECEDENTED WARMTH ARRIVED AT
MID-MONTH AS A SPRAWLING RIDGE OF HIGH PRESSURE DOMINATED THE GREAT
LAKES FOR ALMOST 3 WEEKS. MONTHLY MEAN TEMPERATURES ENDED UP 10 TO
16 DEGREES ABOVE THE LONG TERM AVERAGE...ENOUGH TO PLACE MARCH 2012
AS THE WARMEST THIRD MONTH ON RECORD ALMOST EVERYWHERE EXCEPT FOR
MANISTIQUE. DURING THE WARMEST STRETCH FROM 3/17 TO 3/21...MEAN
DAILY TEMPERATURES AVERAGED AN INCREDIBLE 35 TO 40 DEGREES ABOVE
NORMAL. MANY LOCATIONS REPORTED THE HIGHEST MAXIMUM AND MINIMUM
TEMPERATURE EVER OBSERVED IN MARCH DURING THIS WARM SPELL...
INCLUDING SOME DAYTIME HIGHS IN THE LOW 80S AND OVERNIGHT LOWS IN
THE 50S AND LOW 60S. HARVEY IN MARQUETTE COUNTY LOGGED THE HIGHEST
TEMPERATURE...AN INCREDIBLE 85 ON 3/21. SOME OF THESE DAYS WOULD
HAVE BEEN WARM BY MID-SUMMER STANDARDS. IN RECENT MEMORY...MARCH
2010...2000 AND 1995 WERE ALSO QUITE WARM AND AMONG THE TOP FIVE
WARMEST AT MANY SPOTS. THE EARLY ONSET OF 70- TO 75-DEGREE PLUS
TEMPERATURES BY 3/7 IN MARCH 2000 WAS ALMOST UNPRECEDENTED.

RECORD LOW SNOWFALL AT ALL LOCATIONS DURING MARCH IS AN INCH OR
LESS. MANY LOCATIONS SET THIS MONTHLY RECORD FOR LOW SNOWFALL IN THE
WARM AND DRY MARCH OF 2010. A STRONG EL NINO ALSO RESULTED IN VERY
LOW SNOW TOTALS IN MARCH 1973...WHEN EVEN NORMALLY SNOWY MUNISING
RECORDED A MEAGER 0.5 INCH OF THE WHITE STUFF.

BUT WINTER CAN ALSO SHOW ITS NASTY SIDE DURING MARCH. EVEN ON
3/31...RECORD LOW TEMPERATURES REACH BELOW ZERO AT MANY PLACES...
INCLUDING -17 AT IRONWOOD (3/31/75). DURING THE VERY COLD MARCH
1965...RECORD LOW TEMPERATURES AT THE MARQUETTE NWS DROPPED TO -20
AS LATE AS 3/24/65. ON 3/7/84...THE LOW TEMPERATURE AT IRONWOOD
PLUMMETED TO 34 BELOW ZERO. IN 2003...AN ARCTIC INVASION AT THE
BEGINNING OF THE MONTH DROPPED THE MERCURY AS LOW AS 42 BELOW ZERO
AT EWEN IN ONTONAGON COUNTY ON 3/3. MORE RECENTLY...MARCH 2014
FEATURED LENGTHY PERIODS DOMINATED BY ARCTIC AIRMASSES. THE MEAN
MONTHLY TEMPERATURE THEN RAN 9 TO 13 DEGREES BELOW THE LONG TERM
AVERAGE...EARNING THAT MONTH THE TITLE OF THE COLDEST MARCH ON
RECORD AT IRONWOOD...THE MARQUETTE NWS...MUNISING...MANISTIQUE AND
ONTONAGON AND AS ONE OF THE TOP FIVE COLDEST ELSEWHERE ACROSS UPPER
MICHIGAN.

ALTHOUGH LAKE EFFECT SNOW BECOMES LESS LIKELY DURING MARCH AS LAKE
SUPERIOR TEMPERATURES USUALLY REACH THEIR LOWEST READINGS AND ICE
COVER PEAKS...AVERAGE PRECIPITATION DURING MARCH IS MORE THAN DURING
FEBRUARY BECAUSE THE NORTHWARD MOVING JET STREAM BRINGS MORE
MOISTURE-LADEN LOW PRESSURE SYSTEMS TO THE UPPER GREAT LAKES. THIS
INCREASED STORMINESS RESULTS IN HIGHER AVERAGE SNOWFALL AT INLAND
LOCATIONS THAN IN FEBRUARY. THE AVERAGE MONTHLY SNOW AT IRON
MOUNTAIN DURING FEBRUARY IS 9.1 INCHES...BUT RISES TO 11.1 INCHES IN
MARCH. HEAVY SNOW CAN FALL WHEN LARGE STORM SYSTEMS FUELED BY THIS
ACTIVE MARCH JET STREAM PUSH NORTHEAST FROM THE PLAINS INTO THE
GREAT LAKES. IN FACT...THE SNOWIEST DAY EVER AT THE MARQUETTE NWS
WAS 3/14/97...WHEN A POTENT LOW PRESSURE CENTER MOVED THROUGH
WISCONSIN AND DUMPED 26.2 INCHES OF THE WHITE STUFF...PUSHING THE
SNOW DEPTH TO A RECORD 63 INCHES ON 3/15/97. SINCE THE EARLY WINTER
IN 2001-2002 WAS SO WARM AND LAKE SUPERIOR WATER TEMPERATURES WERE
WELL ABOVE NORMAL LATE IN THE WINTER...HEAVY LAKE EFFECT SNOW FELL
IN MARCH 2002 ONCE VERY COLD AIR PUSHED SOUTH AND CONTRIBUTED TO A
RECORD MARCH SNOWFALL AT THE MARQUETTE NWS (83.1 INCHES)...NEWBERRY
(66.9 INCHES)...AND IRONWOOD (60.8 INCHES). A TOTAL OF 63.5 INCHES
OF SNOW SMOTHERED THE HOUGHTON COUNTY AIRPORT IN MARCH 1976. DURING
THAT SAME MARCH...60.6 INCHES ACCUMULATED AT THE MARQUETTE NWS.

                OUTLOOK FOR SPRING INTO EARLY SUMMER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER
THAN CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE
TEMPERATURE BUT EQUAL CHANCES OF ABOVE AND BELOW NORMAL 3-MONTH
PRECIPITATION ACROSS ALL OF UPPER MICHIGAN IN APRIL THROUGH JUNE
2017.

NOTE THAT STATISTICS FOR THE NATIONAL WEATHER SERVICE OFFICE IN
NEGAUNEE TOWNSHIP ARE BASED ON RECORDS WHICH BEGAN IN OCTOBER 1961.
THIRTY YEAR NORMALS USED ARE FOR THE PERIOD OF 1981 THROUGH 2010.
NOTE ALL TEMPERATURES ARE IN FAHRENHEIT AND PRECIPITATION IS IN
INCHES. ALL CLIMATE DATA LISTED IN THIS PRODUCT ARE UNOFFICIAL. FOR
OFFICIAL DATA...PLEASE REFER TO THE NATIONAL CLIMATIC DATA CENTER.
