...WINTER CONDITIONS ARRIVE FOR THE LATTER HALF OF JANUARY...
JANUARY 2007 HAD 2 VERY DISTINCT PERIODS. THE FIRST PERIOD LASTING
FROM THE 1ST...THROUGH THE 15TH...FEATURED WELL ABOVE NORMAL
TEMPERATURES AND ALMOST NO SNOW ACROSS THE ENTIRE REGION. THIS WARM
PERIOD WAS PROVIDED BY A STUBBORN UPPER LEVEL RIDGE THAT HAD BEEN
SITTING OVER THE EASTERN CONUS SINCE THE MIDDLE OF DECEMBER. THIS
RIDGE KEPT THE NORTHERN JET STREAM FROM DIPPING DOWN INTO THE
NORTHERN CONUS...WHICH TYPICALLY PROVIDES THE GREAT LAKES REGION
WITH COLD TEMPERATURES AND SNOW. JANUARY IS TYPICALLY AN ACTIVE
MONTH FOR WEATHER IN NORTHERN MICHIGAN...BUT THANKS TO THE WEATHER
PATTERN...THE FIRST PART OF JANUARY WAS EXTREMELY QUIET.
HOW WARM WAS THE FIRST HALF OF JANUARY? BELOW IS A LOOK AT HOW SOME
LOCATIONS FARED WITH RESPECT TO THEIR AVERAGE TEMPERATURE FOR THE
FIRST 15 DAYS OF JANUARY (MAX...MIN...AND MEAN VALUES REPRESENT
AVERAGE VALUES FOR THE FIRST 15 DAYS):
SSM HTL APN TVC* GLR* ALL
JAN MEAN 2007 27.2 30.3 31.2 32.6 28.7 30.0
MEAN DEPARTURE +13.5 +11.9 +12.6 +11.0 +10.9 +12.0

____________________________________________________________________
AS THE MIDDLE OF JANUARY APPROACHED...MANY WERE WONDERING IF WINTER
WOULD EVER ARRIVE ACROSS THE AREA. THESE CONCERNS WERE ANSWERED ON
THE 12TH AND 13TH OF JANUARY...AS A COLD FRONT PLOWED ACROSS
NORTHERN MICHIGAN...PUTTING AN END TO THE WARM WEATHER...AND SETTING
UP A MUCH DIFFERENT PATTERN FOR THE REMAINDER OF THE MONTH. THE
UPPER LEVEL RIDGE BROKE DOWN...ONLY TO BE REPLACED BY AN UPPER LEVEL
TROUGH. THIS TROUGH PRODUCED MUCH COLDER TEMPERATURES...AND MORE
PERSISTENT LAKE EFFECT SNOWS ACROSS THE AREA. AS THE MONTH OF
JANUARY ENDED...MANY PLACES IN NORTHERN MICHIGAN HAD NEARLY A FOOT
OF SNOW ON THE GROUND.
HERE IS A LOOK AT HOW SOME LOCATIONS FARED WITH RESPECT TO THEIR
FINAL AVERAGE TEMPERATURES DURING JANUARY 2007 (MAX...MIN...AND
MEAN VALUES REPRESENT AVERAGE VALUES DURING THE MONTH):
SSM HTL APN TVC* GLR* ALL
JAN MAX 2007 26.3 28.9 30.2 31.8 27.7 29.0
MAX DEPARTURE +4.8 +3.0 +4.1 +4.5 +2.5 +3.8
JAN MEAN 2007 19.5 22.4 23.3 25.7 21.3 22.4
MEAN DEPARTURE +6.3 +4.6 +5.5 +4.8 +3.9 +5.0
JAN MIN 2007 12.6 15.9 16.3 19.6 15.0 15.9
MIN DEPARTURE +7.7 +6.2 +6.8 +5.2 +5.4 +6.3

____________________________________________________________________
EVEN WITH THE VERY SLOW START TO THE MONTH...JANUARY ENDED JUST SHY
OF NORMAL WITH REGARDS TO OVERALL SNOWFALL. ALL OF THE SNOWFALL CAME
BETWEEN THE 12TH AND 31ST OF JANUARY...WITH NO SNOW BEFORE THIS
PERIOD. MUCH OF THE SNOW WAS PRODUCED WITH LAKE EFFECT PROCESSES...
WHICH IS TYPICAL FOR JANUARY.
HERE IS A LOOK AT HOW SOME LOCATIONS FARED DURING JANUARY 2007:
SSM HTL APN TVC* GLR*
TOTAL SNOWFALL (IN) 32.7 13.9 22.9 18.7 34.8
DEPARTURE FROM NORMAL -1.9 -4.9 -0.8 -11.7 -4.0
*UNOFFICIAL DATA (OBSERVED AND NORMAL DATA ARE COMPILED FROM
COOPERATIVE OBSERVER SITES)
___________________________________________________________________
ALTHOUGH SNOWFALL MADE A NICE RECOVERY DURING THE MONTH...THE
OVERALL LIQUID PRECIPITATION STILL FAILED TO REACH NORMAL VALUES. A
LOT OF THIS WAS DUE TO THE HIGH SNOW TO LIQUID RATIO. MUCH OF THE
SNOWFALL WAS PURE LAKE EFFECT SNOW...WHICH TYPICALLY HAS VERY LITTLE
MOISTURE IN THE SNOW.
HERE IS A LOOK AT HOW SOME LOCATIONS FARED WITH RESPECT TO LIQUID
PRECIPITATION DURING JANUARY 2007:
SSM HTL APN TVC* GLR*
TOTAL PRECIPITATION (IN) 1.86 0.93 1.08 0.70 0.87
DEPARTURE FROM NORMAL -0.78 -0.68 -0.68 -2.28 -2.18
*UNOFFICIAL DATA (OBSERVED PRECIPITATION IS FROM AUTOMATED SURFACE

OBSERVER SITES IN VICINITY OF ASOS SITES)
___________________________________________________________________
HERE IS THE MORE NOTABLE WEATHER EVENTS DURING JANUARY 2007:
ON THE 5TH AND 6TH OF JANUARY...WARM WEATHER PRODUCED RECORD
HIGH TEMPERATURES IN GAYLORD AND ALPENA. ON THE 5TH...GAYLORD
REACHED 45 DEGREES...WHILE ALPENA REACHED 50. THEN ON THE
6TH...GAYLORD REACHED 38 DEGREES AND ALPENA REACHED 41 DEGREES. THIS
WARM WEATHER WAS PART OF AN EXTENDED PERIOD OF WARMTH LASTING FROM
THE MIDDLE OF DECEMBER...THROUGH THE FIRST HALF OF JANUARY.
ON JANUARY 30TH AND 31ST...LAKE EFFECT SNOW DUMPED AROUND A FOOT OF
SNOW IN AREAS AROUND WHITEFISH POINT AND PARADISE.
