...NORTHERN MICHIGAN FALL IN ALL ITS GLORY...

AS IS USUAL THE CASE FOR NORTHERN MICHIGAN...MUCH OF FALL WAS RATHER
ENJOYABLE WITH TEMPERATURES AVERAGING JUST SLIGHTLY ABOVE NORMAL AND
PRECIPITATION COMING IN WELL BELOW NORMAL FOR MOST SITES.
HOWEVER...AS ALWAYS...THE NUMBERS CAN BE A LITTLE DECEIVING...WITH
THE LAST THREE WEEKS OF FALL DOMINATED BY WINTER WEATHER AND NEAR
RECORD SNOWFALL AMOUNTS. WHY THE DRASTIC CHANGE? WELL...MUCH OF THE
FIRST HALF OF FALL ACROSS NORTHERN MICHIGAN WAS DOMINATED BY
EXPANSIVE RIDGING...SHUNTING RAIN-PRODUCING SYSTEMS WELL NORTH INTO
CANADA AND KEEPING THE GRADUALLY BURGEONING COLD AIR MASS BOTTLED
ACROSS THE ARCTIC. THE ONE EXCEPTION FOR THE DRY REGIME WAS A PAIR
OF DECAYING TROPICAL SYSTEMS...REMNANTS OF HURRICANE "GUSTAV" AND
"IKE" THAT BROUGHT SOME WIDESPREAD MODERATE TO HEAVY RAINS TO MUCH
OF NORTHERN MICHIGAN. WELL...IN TYPICAL FALL FASHION...THE PATTERN
DID AN ABRUPT CHANGE DURING NOVEMBER...WITH DEEP LAYER TROUGHING
EXTENDING RIGHT THROUGH THE GREAT LAKE REGION. THIS ALLOWED A
SUSTAINED SUPPLY OF COLD CANADIAN AND ARCTIC AIR TO MAKE FREQUENT
VISITS TO THE NORTHWOODS...ESPECIALLY DURING THE SECOND HALF OF THE
MONTH. THIS...COMBINED WITH LINGERING SUMMERTIME WARMTH HELD IN THE
EXPANSIVE GREAT LAKES WATERS...SET THE STAGE FOR NUMEROUS BOUTS OF
SIGNIFICANT LAKE EFFECT SNOWS...WITH FAVORED LOCATIONS REPORTING TWO
FEET OR MORE OF SNOW JUST IN THE LAST COUPLE WEEKS OF NOVEMBER AND
NEAR RECORD SNOW DEPTHS.

HERE IS A LOOK AT HOW A FEW LOCATIONS FARED DURING THE FALL OF
2008 WITH RESPECT TO TEMPERATURES: (NOTE: VALUES REPRESENT
DEPARTURE FROM NORMAL MAXIMUM... MEAN...AND MINIMUM TEMPERATURES FOR

HERE ARE SEVERAL OF THE MORE NOTABLE WEATHER EVENTS DURING THE
FALL OF 2008:

- WARMEST TEMPERATURES OF THE SUMMER GREETED THE RESIDENTS OF
NORTHERN MICHIGAN EARLY IN SEPTEMBER...WITH SEVERAL SITES
EXPERIENCING THEIR ONLY 90 DEGREE WEATHER OF THE SEASON. THE 93
DEGREES OBSERVED AT TRAVERSE CITY ON SEPTEMBER 2ND WAS THEIR
WARMEST TEMPERATURE OF THE YEAR.

- SEPTEMBER 4TH...THE REMNANTS FROM WHICH WAS ONCE HURRICANE
"GUSTAV" BROUGHT A STEADY...SOAKING RAIN TO MUCH OF THE
AREA...ESPECIALLY ACROSS NORTHERN LOWER MICHIGAN. RAINFALL AMOUNTS
RANGED FROM 1 TO 3 INCHES...WITH THE HEAVIEST AMOUNTS ALONG AND
SOUTHEAST OF A HOUGHTON LAKE TO ALPENA LINE.

- SEPTEMBER 10TH...FIRST WIDESPREAD TEMPERATURES IN THE 30S OCCURRED
EARLY IN THE MORNING AS HIGH PRESSURE SETTLED OVER THE NORTHWOODS.
THE COLDEST TEMPERATURE WAS AT RACO...WHICH DROPPED TO 30 DEGREES.

- SEPTEMBER 14TH...THE REMNANTS OF DECAYING TROPICAL SYSTEM "IKE"
BROUGHT A SECOND ROUND OF STEADY RAIN TO THE AREA. WHILE NOT AS
IMPRESSIVE AS "GUSTAV"...RAINFALL AMOUNTS STILL AVERAGED A GOOD HALF
INCH OR SO FOR POINT SOUTH OF M-32. AMOUNTS TAPERED OFF
SIGNIFICANTLY TO THE NORTH...WITH SAULT SAINTE MARIE REPORTING ONLY
A TRACE.

- SEPTEMBER 29TH AND 30TH...BEGINS OF THE FIRST SUSTAINED COOL SHOT
OF THE FALL SEASON OVERSPREAD THE NORTHWOODS AS STRONG UPPER LEVEL
LOW PRESSURE APPROACHED THE AREA FROM CENTRAL CANADA. NUMEROUS RAIN
SHOWERS...SOME LAKE ENHANCED...OVERSPREAD THE REGION. WITH ALL THE
CLOUDS AND COOL NORTHWEST WINDS...AFTERNOON HIGHS ONLY MANAGED TO
MAKE INTO THE 50S FOR MOST OF THE AREA.

- THE MONTH OF OCTOBER GOT OFF TO A RATHER COLD START AS A DEEP
UPPER LEVEL DISTURBANCE DUG INTO THE EASTERN GREAT LAKES REGION.
DAYTIME HIGHS FROM THE 1ST THROUGH THE 4TH ONLY MANAGED TO MAKE IT
INTO THE 40S AND LOW TO MID 50S. THESE READINGS WHERE A GOOD 10 TO
15 DEGREES BELOW NORMAL.

- OCTOBER 11TH THROUGH THE 13TH...AS IS OFTEN THE CASE DURING EARLY
FALL...TEMPERATURES WARMED QUICKLY FOLLOWING THE EARLY MONTH COLD
SNAP. AFTERNOON HIGHS THROUGH THIS PERIOD REACHED WELL INTO THE
70S...WITH EVEN A FEW LOWER 80S IN THE TYPICAL WARMER LOCATIONS.

- OCTOBER 26TH THROUGH THE 29TH...THE TYPICAL FALL ROLLER COASTER
TEMPERATURE RIDE CONTINUED AS ANOTHER STRONG UPPER LEVEL DISTURBANCE
SLOWLY ROTATED THROUGH THE GREAT LAKES REGION. TEMPERATURE ONCE
AGAIN FELL WELL BELOW LATE OCTOBER NORMALS...WITH THE AIR BECOMING
COLD ENOUGH FOR SEVERAL BOUTS OF THE FIRST OF THE SEASON LIGHT LAKE
EFFECT SNOW SHOWERS. THE COLD AIR WAS USHERED IN BY SEVERAL ROUNDS
OF SMALL HAIL DURING THE AFTERNOON OF THE 26TH. AS FOR THE
SNOW...WHILE GENERALLY LIGHT...SOME MINOR ACCUMULATIONS DID OCCUR IN
THE TYPICAL SNOWBELT REGIONS OF NORTHWEST LOWER MICHIGAN...WITH A
COUPLE INCHES REPORTED IN SOME LOCATIONS OF ANTRIM AND KALKASKA
COUNTIES. PER THE USUAL...THE STILL WARM LAKE MICHIGAN WATERS KEPT
MOST OF THE PRECIPITATION RAIN NEAR THE IMMEDIATE SHORELINE.

- THE MONTH OF NOVEMBER STARTED OUT ON A MILD NOTE...WITH THE FIRST
WEEK AVERAGING MUCH ABOVE NORMAL...WITH EVEN A FEW RECORD HIGHS SET.
ELECTION DAY...NOVEMBER 4TH...WAS RIGHT IN THE MIDDLE OF THIS WARM
PERIOD...WITH HIGHS WELL INTO THE 60S AND 70S ACROSS THE NORTHWOODS.

- NOVEMBER 9TH AND 10TH...FIRST SIGNIFICANT LAKE EFFECT SNOWS OF THE
SEASON (DON/T WORRY...MANY MORE TO FOLLOW) TARGETS THE TRADITIONAL
SNOWBELT REGIONS OF NORTHWEST LOWER MICHIGAN AND NORTHERN CHIPPEWA
COUNTY. AS IS USUALLY THE CASE IN EARLY SEASON EVENTS...THE HEAVIEST
SNOW WAS CONFINED TO THE INTERIOR ELEVATED REGIONS ON NORTHERN
MICHIGAN. HERE AT THE OFFICE...8.8 INCHES WAS RECORDED FOR THE 24
HOUR PERIOD...WHILE SOME OTHER REPORTS INCLUDED 6 TO 7 INCHES IN
PARTS OF ANTRIM AND KALKASKA COUNTIES...AND 3.5 INCHES AT SAULT
SAINT MARIE.

- NOVEMBER 15TH...OPENING DAY OF THE FAMED FIREARM DEER SEASON
BROUGHT JUST SOME SCATTERED RAIN AND SNOW SHOWERS TO NORTHERN
MICHIGAN AS A COLD FRONT CUT THROUGH THE STATE. HOWEVER...THE
INCOMING COLD AIR SET THE STAGE FOR THE NEXT ROUND OF SIGNIFICANT
LAKE EFFECT SNOW (SEE BELOW)

- NOVEMBER 16TH AND 17TH...LAKE SNOWS ONCE AGAIN TARGET THE
TRADITIONAL SNOWBELT AREAS...WITH AMOUNTS PUSHING 5 TO 10 INCHES
ALONG AND WEST OF THE US-131 CORRIDOR.

- NOVEMBER 19TH...THE WINTER-TIME ALL TOO FAMILIAR ALBERTA CLIPPER
PASSED ACROSS EASTERN UPPER MICHIGAN. THIS...COMBINED WITH SOUTHWEST
FLOW LAKE MICHIGAN ENHANCEMENT...BROUGHT AROUND OF VERY HEAVY SNOW
TO PARTS OF EASTERN UPPER MICHIGAN. TOTALS INCLUDED 8 INCHES AT
ENGADINE...WITH WIDESPREAD 6 AND 7 INCH AMOUNTS ACROSS MUCH OF
CENTRAL MACKINAC AND CHIPPEWA COUNTIES.

- NOVEMBER 20TH AND 21ST...DEEP COLD AIR DROPPING BEHIND THE
DEPARTING CLIPPER SYSTEM KICKED THE LAKE GUNS INTO
OVERDRIVE...ESPECIALLY FOR AREAS WEST OF US-131...WITH SEVERAL
REPORTS OF 6 INCHES OR MORE OF ADDITIONAL ACCUMULATION IN THE
FAVORED AREAS. ON THE OTHER HAND...CONDITIONS CLEARED OUT ACROSS
INTERIOR REGIONS OF NORTHERN LOWER. THIS...COUPLED WITH A FRESH SNOW
PACK...ALLOWED TEMPERATURES TO DROP QUICKLY THE NIGHT OF THE 20TH.
BY MORNING...BOTH GAYLORD (-2F) AND GRAYLING (-6F) DROPPED BELOW
ZERO. THE LOW IN GAYLORD EASILY BROKE THE PREVIOUS RECORD LOW FOR
THE DATE OF 1F SET IN 1987.

- NOVEMBER 24TH AND 25TH...WELL...AS IF LAKE EFFECT WASN/T
ENOUGH...MOTHER NATURE DECIDED A FRESH BLANKET OF WET SYSTEM SNOW
WAS NEEDED ACROSS THE AREA. ALL OF NORTHERN MICHIGAN WAS BLANKETED
WITH 2...TO AS MUCH AS...8 INCHES OF FRESH SNOW ON THE NORTHERN SIDE
OF LOW PRESSURE THAT PIVOTED ACROSS THE LOWER LAKES. FAR
NORTH...MUCH OF THE AREA NORTH OF THE MIGHTY MAC WAS SPARRED THE
HEAVIEST SNOW...WITH JUST AN INCH OR TWO REPORTED...AS THE DEEPEST
MOISTURE NEVER MADE IT THAT FAR NORTH.

- NOVEMBER 27TH...NOT A BAD THANKSGIVING DAY...SAY FOR THE DEEP SNOW
COVER ALREADY IN PLACE...AS JUST A FEW LIGHT SNOW SHOWERS DOTTED THE
LANDSCAPE. IT WAS EVEN A LITTLE MILDER...WITH READINGS GENERALLY IN
THE 30S.

- NOVEMBER 28TH...THE BREAK WAS SHORT-LIVED AS THE LAKE MACHINE ONCE
AGAIN GOT STARTED...THIS TIME TARGETING ANTRIM AND OTSEGO COUNTIES.
A SPOTTER SOUTHEAST OF MANCELONA REPORTED 7 INCHES OF FRESH POWDER.

- NOVEMBER 30TH...WHILE MUCH OF THE MORNING WAS DRY...AN
INTENSIFYING STORM SYSTEM APPROACHING SOUTHERN LOWER MICHIGAN SPREAD
MODERATE TO HEAVY SNOW ACROSS MUCH OF NORTHERN LOWER MICHIGAN DURING
THE AFTERNOON. ONE INTENSE SNOWBAND STAYED NEARLY STATIONARY NEAR
THE SHORELINE OF LAKE MICHIGAN...WITH A BULLSEYE OF 4 TO 8 INCHES
FALLING IN A SHORT PERIOD OF TIME OVER LEELANAU COUNTY. ELSEWHERE...
A GENERAL 2 TO 4 INCHES WAS RECEIVED BY MIDNIGHT.
