==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - JANUARY 2009
...ANOTHER IMPRESSIVE WINTER MONTH WITH COLD AND SNOW...
...5TH COLDEST JANUARY AT FLINT AND 11TH COLDEST AT SAGINAW...
***DOMINANT TEMPERATURE/SNOW TREND...BELOW NORMAL/ABOVE***
ANOTHER IMPRESSIVELY COLD AND STORMY MONTH CONTINUED TO DEAL A HARD
WINTER TO THE INHABITANTS OF SOUTHEAST LOWER MICHIGAN. IT WAS THE
SECOND MONTH IN A ROW FOR COLD (BUT MUCH WORST THAN DECEMBER) AND
ABOVE NORMAL SNOWFALL. WITH AN AVERAGE TEMPERATURES HOVERING IN THE
MID TEENS MUCH OF THE MONTH...FLINT`S AVERAGE TEMPERATURE OF 14.5
WAS THE 5TH COLDEST JANUARY ON RECORD. SAGINAW`S AVERAGE TEMPERATURE
OF 14.9 PLACED 11TH FOR COLDEST JANUARY ON RECORD. WHILE IT WAS NOT AS
SNOWY IN FLINT OR SAGINAW AS AT DETROIT...FLINT`S TOTAL OF 17.1" PLACED
15TH FOR SNOWIEST AND SAGINAW TOTALED 15.2" CAME IN JUST BELOW 20TH
PLACE.
NOT ONLY DID WE SEE A NUMBER OF BELOW ZERO DAYS AT FLINT /9 AT FLINT AND
7 AT SAGINAW - NORMAL FOR THE ENTIRE WINTER 11/...MORE IMPRESSIVE WAS
THE PERSISTENCE OF THE COLD. THERE WERE NO 40 DEGREE DAYS AND JUST A
DAY OR TWO ABOVE FREEZING (TWO AT FLINT AND ONE AT SAGINAW). THE HIGH
OF THE MONTH WAS JUST 34 AT BOTH FLINT AND SAGINAW. FEBRUARY 2007
/AVE 17.3/ AND DECEMBER 2000 /16.8/ WERE TWO RECENT COLD MONTHS BUT
STILL NOT AS COLD AS THIS PAST JANUARY. THE LAST TIME THE AVERAGE
TEMPERATURE IN JANUARY WAS AS COLD OR COLDER WAS JANUARY OF 1994
WHEN THE HIGH TEMPERATURES AVERAGED 22.0 AND LOWS 5.6 AT FLINT...
CREATING A MEAN OF 13.8. AT SAGINAW HIGHS AVERAGED 19.8 AND LOWS JUST
4.3 FOR A MEAN OF 12.1 (BUT LESS SNOW FELL AT BOTH LOCATIONS). THE
TEMPERATURE RANGE IN JANUARY 1994 WAS WIDER THAN THIS PAST JANUARY ON
BOTH SIDES. THE HIGHEST TEMPERATURES WERE IN THE MID 30S TO LOWER 40S
WHILE THE LOWS DROPPED AS LOW AS THE LOWER -20S!
GOING BACK FURTHER TO THE SOME OTHER COLD JANUARIES. IN JANUARY OF
1984...THE AVERAGE HIGH AT FLINT WAS 22.2...LOW 6.5 FOR A MEAN OF 14.3
BUT WITH ONLY 9.0" OF SNOW. ANOTHER WAS JANUARY OF 1982 WHEN THE HIGH
TEMPERATURE AVERAGED 23.4...THE LOW AVERAGED 9.4 FOR A MONTHLY MEAN OF
16.4 (BUT MORE SNOW FELL /19.3"/). THEN...FOUR JANUARIES EARLIER IN
1978...TEMPERATURE HIGHS AVERAGED 25.1 AND LOWS 11.3 (MEAN OF 18.2) BUT
MORE SNOW FELL THAN ALL OF THESE JANUARIES WITH 23.6" - BLIZZARD OF
`78). FINALLY...OUR BITTER COLD WINTER OF 1976-77 CONTAINED A JANUARY
THAT WAS PITIFULLY COLD WITH AN AVERAGE HIGH OF 17.5 AND LOW OF 4.2
DEGREES WITH A MEAN OF JUST 10.9 FOR THE MONTH AND THE COLDEST JANUARY
ON RECORD AT FLINT...SAGINAW AVERAGED A BIT WARMER AT 12.8.
A RECORD LOW TEMPERATURE OF -19 DEGREES WAS SET AT FLINT ON THE
14TH...WHILE SAGINAW FELL TO -10...ALSO A RECORD. ANOTHER MILESTONE OF
SORTS OCCURRED AT THE HERE AT THE NWS IN WHITE LAKE. JANUARY 2009 WAS
OUR COLDEST MONTH /AVERAGE 14.4/ ON RECORD SINCE RECORDS BEGAN THE
WINTER OF 1995-96. HOWEVER...JANUARY OF `94 (LIKE OTHERS) WOULD MOST
LIKELY BE A GOOD CONTENDER FOR COLD BUT IT WAS PRE-RECORD KEEPING.
AND NOW THE SNOW...
FREQUENT SNOWS FOR A SECOND MONTH IN A ROW BROUGHT WELL ABOVE NORMAL
SNOW AMOUNTS TO ALL OF SOUTHEAST LOWER MICHIGAN. OFFICIALLY AT FLINT
BISHOP AIRPORT...17.1" OF SNOW FELL WHILE SAGINAW SAW 15.2". WHILE
SEVERAL DAYS OF LIGHT SNOWS OCCURRED DURING THE MONTH...EXTREME
SOUTHEAST LOWER MICHIGAN GOT SOCKED WITH THE HEAVIEST SNOWS. THE BIGGEST
STORM THAT HIT THE FLINT/SAGINAW AREA OCCURRED ON THE 17-18TH. THE STORM
TRACKED FROM WISCONSIN INTO MID MICHIGAN. GUSTY WARM AIR ADVECTION INTO
THE FRIGID AIR /TEENS/ BROUGHT BLOWING AND DRIFTING SNOW. HEAVIEST
SNOWS RANGED GENERALLY FROM FOUR TO EIGHT INCHES WITH BOTH FLINT AND
SAGINAW NEAR THE LOW END AT 4.1". HIGHER AMOUNTS OF SNOW WERE...6.2" AT
VASSAR...7.1" AT BAY CITY...7.0" AT CASEVILLE AND 8.0" AT FAIRGROVE AND
AUBURN.
IN SPITE OF ALL THE SNOW...THE WATER EQUIVALENTS WERE ON THE LOW SIDE
BECAUSE OF THE EXTREME COLD...MOST AREAS SAW JUST AROUND AN INCH
(SAGINAW RECEIVED JUST 0.77" WHILE FLINT RECEIVED 0.96"). LITTLE IF
ANY PRECIPITATION WAS LIQUID DURING THE COLD MONTH BEING IT EITHER
FROZEN OR FREEZING. HOWEVER...FREEZING RAIN AND/OR DRIZZLE OCCURRED ON
THE 4TH AND 7TH.
FOR THE SECOND MONTH IN A ROW...OUR ANALOGUE WINTERS WERE ON THE MARK
WITH CALLING FOR A COLD MONTH. FOR JANUARY...EIGHT OUT OF THE
ELEVEN JANUARIES SURVEYED WERE COLDER THAN NORMAL. SNOWFALL WAS
WIDESPREAD AND CONTINUED TO BE ABOVE NORMAL AND NOW...ALL AREAS
PARTICIPATED.
FEBRUARY`S PROJECTED TEMPERATURE DATA WAS FINALLY MORE VARIABLE THAN
THE FIRST TWO MONTHS WITH JUST AS MANY CONTAINING ABOVE NORMAL AS BELOW
NORMAL TEMPERATURES (ALONG WITH A FEW NEAR NORMAL). LOOK FOR AN
IMPROVEMENT IN THE TEMPERATURE DEPARTMENT WITH TEMPERATURES AVERAGING
CLOSER TO NORMAL OR ABOVE.
*********************************************************************
A NEW ITEM IN OUR MONTHLY WRITE-UPS THAT I FEEL WILL GIVE A BETTER
IDEA TO THE MONTHS DOMINANT WEATHER TREND FOR BOTH TEMPERATURE AND
DOMINATE PRECIPITATION. THIS IS IN ADDITION TO THE TEMPERATURE AND
PRECIPITATION STATISTICS/DEPARTURES WHICH DON`T ALWAYS REFLECT OUR
DOMINANT MONTHLY WEATHER ACCURATELY. THEREFORE...ALONG WITH OUR
MONTHLY STATISTICS/DEPARTURE...TEMPERATURE AND PRECIPITATION TRENDS
WILL BE SIMPLY INCLUDED...AND REMEMBER THEY MAY NOT ALWAYS AGREE.
