February Recap

           ...FEBRUARY...A MONTH OF VARIATION...

AFTER A PERSISTENTLY COLD JANUARY (LIKE THATS A SURPRISE) WHICH
FEATURED CONSISTENTLY BELOW NORMAL TEMPERATURES...FEBRUARY SHOWED
MUCH MORE VOLATILITY AS CHANGING UPPER AIR PATTERNS BROUGHT
FLUCTUATING TEMPERATURES TO NORTHERN MICHIGAN. SUMMING IT UP
FURTHER...A COOL START AND FINISH TO THE MONTH WAS MORE THAN OFFSET
BY A WEEK OF EXCEPTIONAL WARM CONDITIONS DURING THE MID MONTH PERIOD
(ENOUGH SO THAT TEMPERATURES ACTUALLY AVERAGED SLIGHTLY ABOVE NORMAL
FOR THE MONTH).

INCREASINGLY FROZEN GREAT LAKES (CUTTING DOWN ON THE INFAMOUS LAKE
EFFECT SNOWS) AND MAINTENANCE OF NORTHWEST FLOW OUT OF THE MOISTURE
STARVED CANADIAN TUNDRA...KEPT THE DRY CONDITIONS (OBSERVED THROUGH
THE MONTH OF JANUARY)...GOING THROUGH THE FIRST WEEK OR SO OF
FEBRUARY. THE WEATHER PATTERN KICKED IT UP A NOTCH FOR THE REMAINDER
OF THE MONTH AS GULF MOISTURE BECAME ENTRAINED IN SYSTEMS LIFTING
OUT OF THE SOUTHERN PLAINS. AS A RESULT OF THE ACTIVE MID AND LATE
MONTH PERIOD...BOTH TOTAL PRECIPITATION AND SNOWFALL AVERAGED ABOVE
NORMAL ACROSS NORTHERN MICHIGAN.

NOW...ONTO SOME SPECIFIC NUMBERS FOR THE MONTH. ENJOY.

HERE ARE SOME OF THE MORE NOTABLE WEATHER EVENTS DURING FEBRUARY
2009:

- FEBRUARY 1ST...AFTER A PERSISTENTLY COLD JANUARY...THE MONTH OF
FEBRUARY GOT OFF ON A MUCH MILDER NOTE AS LOW PRESSURE PASSING WELL
NORTH OF THE REGION BROUGHT WARM AND GUSTY SOUTHWEST WINDS TO THE
NORTHWOODS. BY EARLY AFTERNOON ON SUPER BOWL SUNDAY...TEMPERATURES
ACROSS MUCH OF NORTHERN MICHIGAN REACHED WELL INTO THE 30S...WITH
EVEN A COUPLE LOWER 40S THROWN IN FOR GOOD MEASURE. HOWEVER...THE
WARM TEMPERATURES WERE TEMPERED SOMEWHAT BY WINDS GUSTING IN EXCESS
OF 40 MPH...WITH EVEN A 56 MPH GUST OBSERVED AT THE PRESQUE ISLE
LIGHT HOUSE.

- FEBRUARY 4TH AND 5TH...A BRIEF...BUT SIGNIFICANT SHOT OF ARCTIC
AIR PAID A VISIT TO NORTHERN MICHIGAN. AFTER HIGHS STUCK IN THE
SINGLE DIGITS AND LOWER TEENS ON THE 4TH...LIGHT WINDS AND CLEAR
SKIES HELPED DROP EARLY MORNING READINGS ON THE 5TH WELL BELOW
ZERO AWAY FROM THE "WARMING" INFLUENCES OF THE GREAT LAKES. THE COLD
SPOT WENT TO BOTH GAYLORD AND ALPENA...WHICH REPORTED LOWS OF -16F
DEGREES.

- FEBRUARY 6TH THROUGH THE 11TH...A SIGNIFICANT CHANGE IN THE MID AND
UPPER LEVEL PATTERN ACROSS NORTH AMERICA BROUGHT ALMOST A WEEK LONE
"HEAT WAVE" TO THE NORTHERN GREAT LAKES. THE WARM TEMPERATURES
PEAKED ON BOTH THE 7TH AND THE 10TH...WHEN MANY RECORD HIGHS...WITH
TEMPERATURES REACHING THE 40S AND 50S...WERE BROKEN. SOME OF THE
WARMEST TEMPERATURES AND LOCATIONS ON THE 7TH INCLUDED ALPENA AND
TRAVERSE CITY...WHICH MADE IT ALL THE WAY TO 51 AND 50 DEGREES
RESPECTIVELY. IT WAS EVEN WARMER ON THE 10TH...WHEN WIDESPREAD 50S
OVERSPREAD MUCH OF THE AREA SOUTH OF THE MIGHTY MAC. TRAVERSE CITY
TRIED ITS BEST TO PUSH THE 60 DEGREE MARK...MAKING IT A LATE APRIL
LIKE 57 DEGREES. FOR A COMPLETE LIST OF RECORD HIGHS THROUGH THIS
PERIOD...PLEASE SEE THE FOLLOWING RECORD SECTION. PER USUAL THE CASE
IN WINTER...WARM AIR IS OFTEN ACCOMPANIED BY A WETTER PATTERN. A
SIGNIFICANT STORM SYSTEM RIDING UP ACROSS SOUTHERN LOWER MICHIGAN ON
THE 11TH BROUGHT WIDESPREAD PRECIPITATION TO MUCH OF NORTHERN LOWER
MICHIGAN. ALTHOUGH THIS IS A VERY FAVORED STORM PATH FOR SIGNIFICANT
NORTHERN MICHIGAN SNOW...THE LINGERING UNSEASONABLY WARM
TEMPERATURES KEPT MUCH OF THE PRECIPITATION AS RAIN UNTIL THE
MORNING HOURS OF THE 12TH. TOTAL RAINFALL FROM THE STORM REACHED IN
EXCESS OF AN INCH FOR AREAS SOUTHEAST OF A LINE EXTENDING FROM
ALPENA TO HOUGHTON LAKE. THIS RAIN...ACCOMPANIED BY A FAST AND
FURIOUS SNOW PACK MELT...LED TO MANY AREAS OF STANDING WATER AND
RISES IN AREA RIVER AND STREAMS. HOWEVER...DESPITE SOME RIVER FLOOD
WARNING BEING ISSUED...NO SIGNIFICANT FLOODING WAS REPORTED.

- FEBRUARY 12TH...WINTER RETURNS TO NORTHERN MICHIGAN (AND WOULD
REMAIN FOR THE REMAINDER OF THE MONTH) AS OVERNIGHT RAIN CHANGED TO
SNOW...BRINGING A FEW INCHES OF FRESH POWDER (TO MUCH REJOICE WITH
SNOWMOBILERS AND SKIERS)...ESPECIALLY TO THE HIGHLANDS OF NORTHERN
LOWER MICHIGAN.

- FEBRUARY 17TH THRU 19TH...MUCH MORE TYPICAL WINTER CONDITIONS
RETURNED TO THE NORTHWOODS AS LOW PRESSURE FROM THE CENTRAL PLAINS
CUT ACROSS THE STATE...FIRST BRING "SYNOPTIC" SNOW TO THE
AREA...WITH COLD WINDS IN THE WAKE OF THE SYSTEM BRINGING THE ALL TO
FAMILIAR LAKE EFFECT SNOWS TO FAVORED AREAS. BY THE TIME THINGS
WRAPPED UP ON THE EVENING OF THE 19TH...A HALF FOOT OR MORE OF SNOW
WAS REPORTED ACROSS MUCH OF THE AREA...WITH A FOOT OR MORE IN
LOCALIZED LAKE EFFECT AREAS AROUND THE GRAND TRAVERSE BAY REGION.

- FEBRUARY 21ST AND 22ND...ANOTHER STRONG UPPER LEVEL DISTURBANCE
BROUGHT A COMBINATION OF SYSTEM AND LAKE ENHANCED SNOW TO THE GREAT
LAKES REGION. SNOW ADVANCED STEADILY NORTH DURING THE MORNING OF THE
21ST...WITH SNOWFALL RATES APPROACHING 2 INCHES PER HOURS NEAR
CADILLAC. THE "SYSTEM" PART OF THE STORM BROUGHT A GENERAL 6 INCHES
OR MORE TO AREAS ALONG AND SOUTH OF THE M-32 CORRIDOR OVER NORTHERN
LOWER MICHIGAN...WITH AMOUNTS DECREASING QUICKLY NEAR THE STRAITS
AND EASTERN UPPER MICHIGAN. THE BIG WINNER (OR OTHER TERMINOLOGY...
DEPENDING ON HOW ONE FEELS) FOR THE FIRST PART OF THE EVENT WAS
AFOREMENTIONED CADILLAC...WHICH REPORTED A WHOPPING 16 INCHES OF
SNOW. OTHERS INCLUDED MCKINLEY IN OSCODA COUNTY AND ONEKAMA IN
MANISTEE COUNTY WHICH REPORTED 12 INCHES AND 11 INCHES RESPECTIVELY.
ONCE AGAIN...AFTER THE SYSTEM DEPARTED...COLD NORTH TO NORTHWEST
WINDS TARGETED THE GRAND TRAVERSE BAY REGION WITH LAKE EFFECT SNOW
SHOWERS...BRINGING SEVERAL ADDITIONAL INCHES OF ACCUMULATION.

- FEBRUARY 26TH AND 27TH...MOISTURE RICH LOW PRESSURE CUT ACROSS
CENTRAL LOWER MICHIGAN LATE ON THE 26TH...BRINGING A HEAVY WINTRY
MIX OF PRECIPITATION TO ALL OF NORTHERN LOWER MICHIGAN. LOCATION
NORTH OF M-68 RECEIVED SEVERAL INCHES OF SNOW...WITH SEVERAL REPORTS
OF 6 OR MORE INCHES. ACROSS THE REST OF NORTHERN LOWER
MICHIGAN...THE PRECIPITATION FELL AS A MIX OF RAIN...FREEZING
RAIN...SNOW...AND SLEET...LEADING TO VERY HAZARDOUS DRIVING
CONDITIONS. LATE SEASON ARCTIC AIR FOLLOWED THIS STORM...BRINGING
BITING COLD BACK TO THE NORTHWOODS ON THE 27TH.
