Fall Climate Summary

                    ...A ROLLER COASTER AUTUMN...

THIS PAST FALL WILL BE KNOWN AS A SEASON OF EXTREMES...WITH A COOL
AND VERY DAMP OCTOBER BOUNDED BY DRY AND WARM SEPTEMBER AND
NOVEMBER. IN THE END...TEMPERATURES DID COME OUT A TOUCH ON THE WARM
SIDE OF NORMAL...WITH READINGS GENERALLY AVERAGING ONE TO THREE
DEGREES ABOVE NORMAL. PRECIPITATION AVERAGED ABOUT NORMAL...WITH A
VERY WET OCTOBER HELPING COMPLETELY OFFSET A VERY DRY SEPTEMBER AND
NOVEMBER.

PROBABLY THE BIGGEST STORY OF THE SEASON WAS THE TRANQUILITY OF
NOVEMBER...FEATURING HISTORICALLY LOW SNOWFALL TOTALS AND
TEMPERATURES WELL ABOVE AVERAGE. GIVEN THE LOW NOVEMBER SNOW
TOTALS...AS ONE WOULD EXPECT...(SINCE THE TRUE BEGINNING OF THE SNOW
SEASON BEGINS IN NOVEMBER)...THIS WAS ONE OF THE LEAST SNOWIEST
FALLS ON RECORD ACROSS NORTHERN MICHIGAN. THIS WAS IN STARK CONTRAST
TO JUST A YEAR AGO...WHEN NORTHERN MICHIGAN WAS IN THE MIDST OF
HISTORICAL SNOWY START TO THE SNOW SEASON.

____________________________________________________________________

HERE ARE SEVERAL OF THE MORE NOTABLE WEATHER EVENTS DURING THE
FALL OF 2009:

- THE FIRST 20 DAYS OF SEPTEMBER WENT RAIN FREE IN MOST
LOCATIONS...WHICH WAS THE MOST NOTEWORTHY WEATHER OCCURRENCE DURING
THE MONTH.

- HIGH WINDS ROARED THROUGH THE REGION OVERNIGHT FROM THE 28TH TO
THE 29TH OF SEPTEMBER. THE STRONGEST WIND GUST WAS RECORDED AT BIG
SABLE POINT WITH REPORTED A WIND GUST OF 52 MPH. FRANKFORT ALSO
REPORTED A WIND GUSTS AT 46 MPH. SOME PLACES DOWNSTATE EVEN REPORTED
SOME DAMAGE FROM THESE WINDS.

- OCTOBER STARTED OUT HISTORICALLY COLD...WITH NEARLY ALL OF THE FIRST
18 DAYS OF THE MONTH AVERAGING BELOW...TO MUCH BELOW...NORMAL. BY
THE 18TH...MOST LOCATIONS HAD EXPERIENCED ONE OF THE TOP 5 COLDEST
STARTS TO OCTOBER SINCE 1950. AS ONE WOULD EXPECT DURING
OCTOBER...THE EXCEEDINGLY COLD TEMPERATURES SPARKED THE FIRST SNOW
OF THE YOUNG SNOW SEASON ON OCTOBER 10TH...WITH INTERMITTENT
EPISODES OF LIGHT SNOW SHOWERS CONTINUING THROUGH THE 15TH.
HOWEVER...GIVEN THE GENERAL LIGHT NATURE OF THE ACTIVITY AND THE
STILL WARM GROUND TEMPERATURES...MOST AREAS RECEIVED JUST TRACE
AMOUNTS OF SNOW THROUGH THIS PERIOD...WITH ANY LIGHT ACCUMULATION
ONLY FOUND ACROSS PARTS OF EASTERN UPPER MICHIGAN AND THE INTERIOR
HIGHLANDS OF NORTHWEST LOWER MICHIGAN. EVEN IN THESE LOCATIONS...
SNOWFALL TOTALS FOR THE MONTH REMAINED UNDER AN INCH.

- A SHIFT IN THE UPPER LEVEL PATTERN BROUGHT MODERATING TEMPERATURES
FOR MUCH OF THE REMAINDER OCTOBER...WITH MANY OF THE FINAL 13 DAYS OF THE
MONTH AVERAGING ABOVE NORMAL. THIS PARTIALLY OFFSET THE COLD
START...AND AS A RESULT...MOST AREAS FELL SHORT OF RECORDING ONE OF
THEIR COLDER OCTOBERS. THE LARGEST DAILY DEPARTURE DURING THIS
PERIOD WAS ON THE 30TH...WHEN GUSTY SOUTH WINDS AHEAD OF AN
APPROACHING STRONG COLD FRONT HELPED TEMPERATURES SOAR WELL INTO THE
60S (THE FIRST 60 DEGREE TEMPERATURES OF THE MONTH). THE WARMEST
TEMPERATURE REPORTED WAS 68 DEGREES...WHICH OCCURRED AT SEVERAL
LOCATIONS...INCLUDING TRAVERSE CITY. HOWEVER...THE WARM-UP WAS SHORT
LIVED...AS THE STRONG FRONT PLOWED ACROSS THE AREA DURING THE
EVENING...QUICKLY DROPPING TEMPERATURES AND SETTING UP A BRIEF
PERIOD OF VERY GUSTY WINDS. SOME OF THE HIGHER GUSTS REPORTED
INCLUDED 53 MPH AT GAYLORD AND 50 MPH AT EAST JORDAN. THERE WAS ALSO
A CONFIRMED REPORT OF A GUST OF 73 MPH AT MID-SPAN OF THE MACKINAC
BRIDGE...WHICH IS 200 FT ABOVE THE WATER SURFACE.

- NOVEMBER 1ST THROUGH THE 6TH...THE MONTH BEGAN AS MOST NOVEMBER
DO...FEATURING COOL TEMPERATURES AND SOME INTERMITTENT PERIODS OF
LIGHT SNOW. NORMALLY...THIS WOULD NOT BE NOTEWORTHY...BUT THIS WAS
THE ONLY SUSTAINED PERIOD OF NEAR TO COOL THAN NORMAL CONDITIONS FOR
THE MONTH. IN ADDITION...SNOW WOULD NOT BE REPORTED AGAIN UNTIL THE
THE LAST WEEK OF NOVEMBER...SIMPLY INCREDIBLE!

- NOVEMBER 15TH...THE GREAT NORTHERN MICHIGAN HOLIDAY...ALSO NOTED
AS THE OPENER OF FIREARM DEER SEASON...FEATURED TEMPERATURES MORE
TYPICAL FOR MID NOVEMBER AS A COLD FRONT PLOWING ACROSS THE STATE
DROPPED EARLY MORNING READINGS IN THE 50S TO THE 30S AND 40S BY
AFTERNOON. OTHERWISE...THE PERSISTENT DRY CONDITIONS CONTINUED UNDER
PARTLY TO MOSTLY CLOUDY SKIES.

- NOVEMBER 26TH...TURKEY DAY WAS RATHER WET...AND SOMEWHAT
WHITE...AS UPPER LEVEL LOW PRESSURE CROSS THE NORTHERN LAKES KEPT
CONDITIONS UNSETTLED THROUGHOUT THE DAY. SOME RAINFALL TOTALS WHERE
RATHER IMPRESSIVE...WITH 1.22 INCHES REPORTED NEAR KINGSLEY AND 1.10
INCHES NEAR FRANKFORT. AS MENTIONED...THE RAIN GRADUALLY TURNED OVER
TO SNOW AS THE DAY WORN ON...WITH MOST AREAS SEEING AT LEAST SOME OF
THE WHITE STUFF BY EARLY ON THE 27TH. HOWEVER...SNOWFALL AMOUNTS
GENERALLY REMAINED LIGHT...WITH MOST LOCATIONS REPORTING JUST A
DUSTING OF SNOW. THERE WHERE SOME EXCEPTIONS...ESPECIALLY ACROSS THE
HIGHLANDS OF NORTHERN LOWER MICHIGAN IN FAVORED NORTHWEST FLOW LAKE
INDUCED SNOW AREAS. AMOUNTS APPROACHED 2 INCHES JUST WEST AND
NORTHWEST OF GAYLORD...WITH JUST OVER AN INCH OBSERVED HERE AT THE
OFFICE 9 MILES SOUTH SOUTHWEST OF GAYLORD.

- NOVEMBER 30TH...WEAK CLIPPER SYSTEM TRAVERSING THE NORTHERN LAKES
BROUGHT THE FIRST WIDESPREAD MEASURABLE SNOW OF THE SEASON...WITH
MOST AREAS SEEING AT LEAST AN INCH OR SO. HOWEVER...LOCALLY HEAVIER
AMOUNTS WERE REPORTED NORTH OF THE BRIDGE...WITH SOME LOCATIONS
REPORTING 4 TO 6 INCHES OF SNOW IN EASTERN UPPER.
