...GREAT LAKES WATER LEVELS REMAIN WELL BELOW NORMAL IN MARCH...

INCREASED EVAPORATION DUE TO VERY WARM LAKE WATERS AND A LACK OF
SIGNIFICANT WINTER ICE HAS RESULTED IN WELL BELOW NORMAL GREAT LAKES
WATER LEVELS FOR THE PAST SEVERAL YEARS. IN COMBINATION WITH DROUGHT
THAT PLAGUED THE LOWER LAKES THROUGH MUCH OF 2012...THE WATER LEVEL
ON LAKES MICHIGAN-HURON DROPPED TO JUST BELOW THE RECORD LOW IN
NOVEMBER THROUGH JANUARY. INCREASED PRECIPITATION IN LATE JANUARY
THROUGH MARCH HELPED RAISE WATER LEVELS TO 3 INCHES ABOVE THE
RECORD LOW BY LATE MARCH. BUT LEVELS ON LAKES MICHIGAN-HURON WERE
STILL ALMOST 26 INCHES BELOW THE LONG TERM AVERAGE AT THE END OF THE
MONTH. AS IS TYPICAL IN MARCH...LAKE SUPERIOR WATER LEVELS FELL
SLOWLY...HOLDING A BIT MORE THAN A FOOT BELOW NORMAL THROUGH 3/31.

PERSISTENT COLD DURING THE SECOND HALF OF JANUARY...FEBRUARY...AND
MARCH MAINTAINED SIGNIFICANT ICE COVER ON THE BAY OF GREEN BAY
THROUGH MARCH. SLOWLY MODERATING TEMPERATURES IN LATE MARCH TENDED
TO ALLOW FOR SOME RETREAT IN THE ICE COVERAGE. ICE COVER ON LAKE
SUPERIOR WAS LIMITED TO MAINLY THE NEARSHORE AREAS AND IN THE MORE
SHELTERED BAYS.

HIGHEST REPORTED TEMPERATURE...55 AT LA BRANCHE IN MENOMINEE COUNTY
                                ON 3/28...AT PELKIE IN BARAGA COUNTY
                                ON 3/29 AND AT KENTON IN HOUGHTON
                                COUNTY ON 3/29

LOWEST REPORTED TEMPERATURE...-19 AT HERMAN IN BARAGA COUNTY ON 3/3
                               AND AT CLARKSBURG-CHAMPION IN
                               MARQUETTE COUNTY ON 3/17

                                 HOUGHTON COUNTY

LOWEST MONTHLY PRECIPITATION...1.32 INCHES AT MARQUETTE CITY

HIGHEST MONTHLY SNOWFALL...64.4 INCHES AT ROCKLAND IN ONTONAGON
                            COUNTY

LOWEST MONTHLY SNOWFALL...7.2 INCHES AT MANISTIQUE

GREATEST SNOW DEPTH...53 INCHES AT ROCKLAND ON 3/20

A RESILIENT WINTER WEATHER REGIME DOMINATED THE GREAT LAKES THROUGH
MARCH 2013 AS THE NORTHWEST FLOW ALOFT AROUND A PERSISTENT UPPER
TROUGH IN SOUTHEAST CANADA FUNNELED NUMEROUS POLAR AIRMASSES INTO
THE EASTERN AND CENTRAL UNITED STATES. MONTHLY MEAN TEMPERATURES
RANGED FROM 1 TO 2 DEGREES BELOW NORMAL OVER THE EAST TO AS MUCH AS
5 DEGREES BELOW AVERAGE OVER NORTHWEST UPPER MICHIGAN. IN THIS
AREA...MARCH AVERAGED ONLY ABOUT 5 DEGREES WARMER THAN FEBRUARY EVEN
THOUGH THE THIRD MONTH TYPICALLY RUNS 8 TO 10 DEGREES WARMER THAN
FEBRUARY. THESE NEGATIVE TEMPERATURE ANOMALIES WERE DUE MAINLY TO
CHILLY DAYTIME HIGH TEMPERATURES. IN FACT AT THE MARQUETTE NWS AND
THE HOUGHTON COUNTY AIRPORT...THERE WERE JUST 2 DAYS IN MARCH WHEN
THE MERCURY REACHED 40 OR HIGHER...COMPARED TO A NORMAL OF 9 AND 6
DAYS RESPECTIVELY. THE LAST MARCH WHEN THERE WERE FEWER 40-DEGREE OR
HIGHER MAXIMUMS AT THESE LOCATIONS WAS IN 1965...WHEN THE
THERMOMETER REACHED 40 OR BETTER ONLY ONCE AT THE MARQUETTE NWS BUT
NOT AT ALL AT HOUGHTON.

A FEW LOCATIONS REPORTED A HIGH TEMPERATURE IN THE 50S ON ONLY TWO
DAYS THE WHOLE MONTH...3/28 AND 3/29...THE ONLY TWO DAYS WHEN THE
MARQUETTE NWS SAW A MAXIMUM OF 40 OR BETTER. THE MERCURY FELL BELOW
ZERO AT AT LEAST A COUPLE OF LOCATIONS ON 3/2 THRU 3/5...3/7...
3/8...3/14...3/17...3/18...3/22 AND 3/28. READINGS DIPPED TO -10 OR
LOWER ON 3/3...3/4...3/14...3/17 AND 3/22 AT SOME OF THE INTERIOR
COLD SPOTS.

WITH A PERSISTENT UPPER TROUGH DOMINATING CENTRAL AND EASTERN UPPER
MICHIGAN IN MARCH 2013...MONTHLY PRECIPITATION AND SNOWFALL RAN
ABOVE NORMAL AT MOST LOCATIONS...THANKS MAINLY TO AN ACTIVE MID-
MONTH PERIOD THAT FEATURED THE PASSAGE OF SEVERAL DEEP...MOISTURE-
LADEN LOW PRESSURE SYSTEMS THROUGH THE WEST AND CENTRAL GREAT LAKES.
IN GENERAL...THE HEAVIEST WATER EQUIVALENT PRECIPITATION AND SNOW
FELL OVER THE WEST AND NORTH CENTRAL...WHERE MONTHLY TOTALS EXCEEDED
3 INCHES... AS MUCH AS 150 PERCENT OF NORMAL...AND 50 INCHES...150
TO 250 PERCENT OF NORMAL...RESPECTIVELY AT SOME HIGHER TERRAIN
LOCATIONS. IN FACT...MARCH 2013 GOES DOWN IN THE RECORD BOOKS AS ONE
OF THE TOP 10 SNOWIEST THIRD MONTHS IN A SWATH FROM NEGAUNEE IN
MARQUETTE COUNTY TO MUNISING AND NEWBERRY. LOCATIONS OVER SOUTHEAST
UPPER MICHIGAN SAW THE LEAST PRECIPITATION AND SNOWFALL...BUT EVEN
THERE MONTHLY TOTALS WERE CLOSE TO NORMAL.

THE TWO MOST SIGNIFICANT MARCH STORM SYSTEMS IMPACTED UPPER MICHIGAN
ON 3/11 AND 3/18 INTO 3/21. THE FIRST OF THESE TRACKED NORTH THROUGH
LAKE MICHIGAN AND ACROSS THE EASTERN U.P. ON 3/11. SNOW IN ADVANCE
OF THIS LOW INVADED UPPER MICHIGAN FROM SOUTH TO NORTH IN THE
EVENING ON 3/10 BUT MIXED WITH RAIN EAST OF A LINE FROM MARQUETTE TO
IRON MOUNTAIN AS WARMER AIR SURGED INTO THIS AREA CLOSER TO THE
TRACK OF THE LOW PRESSURE CENTER. SNOW FELL HEAVY AT TIMES OVER THE
WEST AND NORTH CENTRAL...WHERE NORTH WINDS GUSTING UP TO 30 TO 35
MPH CAUSED CONSIDERABLE BLOWING SNOW BEFORE THE WINDS BEGAN TO
DIMINISH IN THE AFTERNOON ON 3/11. BY THE TIME THE LOW MOVED INTO
ONTARIO AND THE STEADY SNOW DIMINISHED IN THE EVENING ON 3/11...
STORM TOTAL SNOWFALL EXCEEDED A FOOT AT SOME OF THE HIGHER TERRAIN
LOCATIONS OF THE WEST AND NORTH CENTRAL. A LOCATION NEAR WINONA IN
HOUGHTON COUNTY LOGGED A TOTAL OF 19.5 INCHES TO LEAD REPORTING
STATIONS...BUT ANOTHER SPOT OVER THE HIGHER TERRAIN IN MARQUETTE
COUNTY JUST NORTHEAST OF ISHPEMING REPORTED 19.1 INCHES. THIS SAME
SITE HAD A SNOW DEPTH OF 52 INCHES AT DAWN ON 3/12.

A LOW PRESSURE SYSTEM TRACKING FROM MINNESOTA INTO ONTARIO CAUSED A
BAND OF MODERATE SNOW TO MOVE ACROSS UPPER MICHIGAN ON 3/18 AND INTO
THE EARLY MORNING HOURS ON 3/19...DROPPING 3 TO 6 INCHES OF THE
WHITE STUFF AT MOST PLACES. AFTER THE LOW MOVED INTO ONTARIO AND THE
STRENGTHENING NORTHWEST WIND AROUND THE SLOW MOVING CYCLONE
ADVECTED MUCH COLDER AIR INTO THE UPPER GREAT LAKES...THE
PRECIPITATION TRANSITIONED TO AN EXTENDED PERIOD OF MODERATE TO
HEAVY LAKE EFFECT SNOW. THIS SNOW FELL HEAVIEST IN THE NORTHWEST
WIND SNOW BELTS AND PERSISTED INTO 3/20 OVER THE WEST AND 3/21 TO
THE EAST OF MARQUETTE. NORTHWEST WINDS GUSTING AS HIGH AS 40 MPH ON
3/19 CAUSED CONSIDERABLE BLOWING SNOW IN THESE AREAS. INCLUDING THE
SNOW THAT FELL ON 3/18 INTO 3/19...AS MUCH AS 32.2 INCHES OF THE
WHITE STUFF PILED UP AT ROCKLAND IN ONTONAGON COUNTY...LIFTING THE
SNOW DEPTH AT THAT LOCATION TO 53 INCHES ON 3/20. OTHER NOTABLE SNOW
TOTALS FOR 3/18 THROUGH 3/21 WERE 30.0 INCHES AT TWIN LAKES IN
HOUGHTON COUNTY... 29.7 INCHES AT GRAND MARAIS IN ALGER COUNTY...
20.4 INCHES AT MUNISING...AND 20.3 INCHES AT HERMAN IN BARAGA COUNTY.

ALTHOUGH MARCH USUALLY GOES OUT LIKE A LAMB...THAT WAS NOT THE CASE
IN 2013. A STRONG COLD FRONT PASSED BY ON 3/31...BRINGING SCATTERED
TO NUMEROUS SNOW SHOWERS...MIXED WITH RAIN OVER THE FAR SOUTH
CENTRAL FOR EASTER SUNDAY. IN THE WAKE OF THE FRONTAL PASSAGE...
NORTH TO NORTHWEST WINDS GUSTING AS HIGH AS 45 TO 50 MPH NEAR LAKE
SUPERIOR DROVE COLDER AIR INTO THE UPPER GREAT LAKES. HEAVY SNOW
SHOWERS DEVELOPED EAST OF MARQUETTE IN THE EVENING ON 3/31 AND
CONTINUED AS THE CALENDAR TURNED FROM MARCH TO APRIL. WITH
SIGNIFICANT SNOW LINGERING ON EASTER SUNDAY AND A FRESH SURGE OF
COLD AIR ARRIVING...SOME COMMENTED THE HOLIDAY FELT MORE LIKE
CHRISTMAS.

WHAT MADE MARCH 2013 SEEM SO HARSH WAS THE STARK DIFFERENCE BETWEEN
THE WEATHER THIS YEAR AND IN 2012. RECORD WARMTH DOMINATED UPPER
MICHIGAN IN MARCH A YEAR AGO...WITH NUMEROUS RECORD HIGH DAILY AND
MONTHLY MEAN TEMPERATURES FALLING BY THE WAYSIDE...INCLUDING THE
EARLIEST OCCURRENCE OF 80-DEGREE TEMPERATURES AT SOME PLACES.
WHEREAS THE SNOW HAD COMPLETELY DISAPPEARED BY MID-MARCH IN 2012...
MANY HIGHER TERRAIN LOCATIONS OVER THE WEST AND NORTH CENTRAL
REPORTED SNOW DEPTHS IN EXCESS OF 30 INCHES THROUGH 3/31 IN 2013.

MORE TO COME LATER.

                           MAY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE OVER UPPER
MICHIGAN IN MAY 2013...EXCEPT A GREATER THAN CLIMATOLOGICAL CHANCE
OF A BELOW NORMAL MONTHLY TEMPERATURE OVER THE FAR WEST. THE CPC
INDICATES EQUAL CHANCES OF ABOVE AND BELOW NORMAL MONTHLY
PRECIPITATION OVER ALL OF UPPER MICHIGAN IN MAY.

                          MAY CLIMATOLOGY

MAY BRINGS A CONTINUED MODERATION IN TEMPERATURE AS DAYLIGHT
CONTINUES TO LENGTHEN. POSSIBLE SUNSHINE INCREASES FROM 863 MINUTES
ON 5/1 TO 932 MINUTES ON 5/31. THE AVERAGE TEMPERATURE IN MAY IS 12
TO 13 DEGREES HIGHER THAN IN APRIL. ALTHOUGH AVERAGE HIGH
TEMPERATURES REACH AROUND 70 BY MEMORIAL DAY OVER INLAND AREAS...
THE RELATIVELY COLD WATERS OF THE GREAT LAKES OFTEN KEEP SHORE
COMMUNITIES UP TO 20 DEGREES COOLER IN THE AFTERNOON. MORNING
TEMPERATURES FREQUENTLY SLIP BELOW FREEZING AT THE BEGINNING OF
MAY...BUT AVERAGE LOW TEMPERATURES RISE ABOVE 40 AFTER MID MONTH.

THE INCREASE IN AVERAGE TEMPERATURE RESULTS IN A GREATER THREAT OF
SHOWERS AND THUNDERSTORMS. AVERAGE PRECIPITATION IS 10 TO 40 PERCENT
HIGHER THAN IN APRIL...WITH THE GREATEST AMOUNTS MOST LIKELY NEAR
THE WISCONSIN BORDER WHERE THE STABILIZING INFLUENCE OF THE GREAT
LAKES IS LESS.

MAY IS GENERALLY A TEMPERATE MONTH...BUT WINTER CHILL IS STILL
POSSIBLE. ALTHOUGH AVERAGE TEMPERATURES RISE SHARPLY...FROST OFTEN
OCCURS AT THE END OF MAY AS RECORD LOW TEMPERATURES REMAIN BELOW
FREEZING THE ENTIRE MONTH AT MANY LOCATIONS. NEWBERRY SAW THE
MERCURY PLUNGE ALL THE WAY TO 19 AS LATE AS 5/24...IN 1925. MAY 1997
GOES DOWN IN THE RECORD BOOKS AS ONE OF THE COLDEST EVER AT ALL
REPORTING STATIONS WITH MONTHLY TEMPERATURES AS MUCH AS SEVEN TO
EIGHT DEGREES BELOW NORMAL. IN FACT...THIS MONTH IS THE COLDEST
FIFTH MONTH EVER AT MANISTIQUE (AVERAGE TEMPERATURE 44.4)...IRON
MOUNTAIN (45.9) AND ONTONAGON (46.6) AS WELL AS IN THE TOP TEN
COLDEST AT MOST OTHER UPPER MICHIGAN LOCATIONS. EVEN MORE
RECENTLY...MAY 2002 LANDED IN THE LIST OF TOP TEN COLDEST. MONTHLY
TEMPERATURES IN MAY 2002 AVERAGED 5 TO 7 DEGREES BELOW NORMAL AT
MOST SITES. AT MUNISING...THE MERCURY AVERAGED 9 DEGREES BELOW
NORMAL (41.5) AND THE MONTH GOES DOWN IN THE RECORD BOOKS AS THE
COLDEST MAY EVER. AT STATIONS WITH A LONGER TERM RECORD...MAY 1954
STANDS OUT AS VERY CHILLY...IN FACT THE COLDEST EVER AT THE HOUGHTON
COUNTY AIRPORT (41.8)...WHEN MONTHLY TEMPERATURES FELL OVER EIGHT
DEGREES BELOW NORMAL.

SNOW CAN STILL PLAGUE UPPER MICHIGAN DURING MAY. A LATE SEASON
SNOWSTORM OCCURRED IN CENTRAL UPPER MICHIGAN ON 5/9-5/10/90...WHEN
AN IMPRESSIVE 22.4 INCHES OF HEAVY WET SNOW FELL AT THE MARQUETTE
NWS...11 INCHES BLANKETED IRON MOUNTAIN...AND 7 INCHES FELL ON
MUNISING. DURING THE CHILLY MAY 1997...13 INCHES OF THE WHITE STUFF
ACCUMULATED AT ONTONAGON ON 5/12 AND 11.3 INCHES SMOTHERED IRONWOOD.
NEWBERRY WAS STRUCK BY AN EVEN LATER MAY SNOWSTORM...10 INCHES
ACCUMULATED THERE ON 5/23 AND 5/24 BACK IN 1917. MEASURABLE SNOW AS
LATE AS MEMORIAL DAY IS NOT UNPRECEDENTED...IRONWOOD RECORDED 3.7
INCHES OF SNOW ON 5/28/65.

ALTHOUGH SNOW CAN STILL FALL IN MAY...SPRING HEAT WAVES CAN ALSO
BRING MID SUMMER HEAT TO UPPER MICHIGAN. ON 5/31 IN 1934...BOTH IRON
MOUNTAIN AND IRONWOOD RECORDED MONTHLY RECORD 100 DEGREE HIGH
TEMPERATURES. RECORD HIGH TEMPERATURES ARE IN THE 90S EVERYWHERE BY
MONTHS` END...EXCEPT AT MANISTIQUE WHERE A SOUTHERLY FLOW OFF LAKE
MICHIGAN OFTEN KEEPS AFTERNOON MAXIMUM TEMPERATURES FROM GETTING AS
HIGH AS FARTHER INLAND. MAY 1977 AND 1998 ARE THE WARMEST MAYS IN
RECENT MEMORY. MAY 1977 IS THE WARMEST ON RECORD AT IRON MOUNTAIN
(62.4)...THE MARQUETTE NWS (59.4)...THE HOUGHTON COUNTY AIRPORT
(58.1) AND MUNISING (57.5). MAY 1998 GOES DOWN IN THE RECORD BOOKS
AS THE WARMEST ON RECORD AT NEWBERRY (59.1) AND IN THE TOP FIVE
WARMEST AT MANY OTHER PLACES. MAY 2000 SAW A VERY SUMMERLIKE WEEK IN
THE EARLY PART OF THE MONTH...AND TEMPERATURES AVERAGED 20 DEGREES
ABOVE NORMAL AT MANY LOCATIONS BETWEEN 5/3 AND 5/8. BARAGA SAW THE
MERCURY REACH 90 ON 5/5/2000...AND THE MARQUETTE NWS BROKE FOUR
DAILY RECORD HIGH TEMPERATURES DURING THAT 6-DAY STRETCH. IN FACT...
THE WEEK BETWEEN 5/3/00 AND 5/8/00 IS THE WARMEST 6-DAY PERIOD ON
RECORD IN EARLY MAY AT THE MARQUETTE NWS. MORE RECENTLY...MAY 2010
FEATURED A MEAN MONTHLY AVERAGE TEMPERATURE 3 TO 5 DEGREES ABOVE
NORMAL.

                          OUTLOOK FOR SUMMER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
OVER THE SOUTHEAST HALF OF UPPER MICHIGAN IN JUNE THROUGH AUGUST
2013 BUT EQUAL CHANCES OF AN ABOVE AND BELOW NORMAL 3-MONTH MEAN
TEMPERATURE OVER THE NORTHWEST HALF. THE CPC IS FORECASTING AN EQUAL
CHANCE OF ABOVE AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF
UPPER MICHIGAN IN JUNE THROUGH AUGUST.
