====================================================================
...HIGH VARIABILITY AND NEAR NORMAL SNOWFALL CHARACTERIZES JANUARY
2013...

A HIGH AMPLITUDE AND GENERALLY PROGRESSIVE PATTERN HELPED DRIVE THE
MONTH`S WEATHER TOWARD BOTH WARM AND COLD EXTREMES DURING THE MONTH
OF JANUARY. THE TWO WEEKS OF THE MONTH WERE CHARACTERIZED BY A
GRADUAL REBOUND OF TEMPERATURES FROM DAYTIME HIGHS IN THE UPPER
TEENS AND MID 20S, THROUGH THE 30S AND 40S, EVENTUALLY REACHING 60
AND 57 DEGREES IN FLINT AND SAGINAW RESPECTIVELY ON THE 12TH. THIS
PROLONGED JANUARY THAW WAS THE RESULT OF A SLOW MOVING CLOSED LOW
OVER THE SOUTHEAST UNITED STATES THAT SLOWLY BUT SURELY FORCED VERY
HIGH AMPLITUDE RIDGING ACROSS SOUTHEAST MICHIGAN. IN THE WAKE OF THE
THAW, MORE CLIMATOLOGICALLY NORMAL NORTHWEST FLOW SETTLED IN ACROSS
THE GREAT LAKES BEFORE A NOTEWORTHY ARCTIC OUTBREAK OCCURRED DURING
THE THIRD WEEK OF THE MONTH. AFTER A BRIEF WARMUP INTO THE UPPER 40S
AHEAD OF THE RESPONSIBLE SYSTEM, THE HIGH AND LOW TEMPERATURES FOR
DETROIT ON JANUARY 22ND REACHED ONLY 12F AND -1F RESPECTIVELY. FLINT
RECORDED AN EQUALLY IMPRESSIVE RANGE OF 10F AND -1F AS DID SAGINAW,
WHICH REGISTERED 8F AND 0F FOR THE DAY. IN FLINT, THE HIGH OF ONLY
10 DEGREES TIED THE PREVIOUS RECORD MINIMUM HIGH (1922) FOR THAT
DAY. YET ANOTHER OSCILLATION OF THE PATTERN OCCURRED LATER IN THE
MONTH, WHEN THE RETURN OF STRONG RIDGING CAUSED TEMPERATURES AT ALL
THREE SOUTHEAST MICHIGAN CLIMATE SITES TO SKYROCKET TO NEW RECORDS
FOR JANUARY 30TH. DETROIT REACHED A HIGH OF 62 (53 IN 1969), FLINT
REACHED 58 (51 IN 1988), AND SAGINAW REACHED 56 (50 IN 1988). ALL
CONSIDERED, THE PERIODS OF WARMTH WERE SUFFICIENT TO PUSH THE FLINT
AREA`S MONTHLY AVERAGE TEMPERATURE TO 26.9 DEGREES, +4.5 DEGREES
ABOVE THE 22.4 JANUARY NORMAL.

DESPITE THE MONTH`S GREATEST SNOWFALLS COMING IN AT ONLY 2.4" IN
FLINT AND 2.1" IN SAGINAW, THEIR MONTHLY SNOWFALL TOTALS STILL
FINISHED NEAR NORMAL, ALBEIT THE LOWER SIDE OF NORMAL. FLINT`S
JANUARY TOTAL OF 10.6" WAS -2.5" BELOW THE 13.1" AVERAGE FOR THE
MONTH WHILE THE 8.0" THAT FELL IN SAGINAW REPRESENTED A SLIGHTLY
LARGER DEFICIT AT -3.9" BELOW THE 11.9" NORMAL. FOR THE SEASON,
FLINT`S SNOW TOTAL STANDS AT 21.7", -6.1" BELOW THE 27.8" SEASONAL
NORMAL. SIMILARLY, SAGINAW STANDS AT 17.8", OR -7.0" BELOW THE 24.8"
SEASONAL NORMAL. IN ADDITION, MULTIPLE RAINFALLS BETWEEN A HALF INCH
AND AN INCH AT BOTH FLINT AND SAGINAW CONTRIBUTED TO RATHER HIGH
MONTHLY PRECIPITATION TOTALS. THE MONTHLY TOTAL OF 3.90" OF
PRECIPITATION MADE IT THE 2ND WETTEST (#1 4.02" IN 2006) IN FLINT`S
HISTORICAL RECORD WHILE THE 3.26" THAT WAS MEASURED IN SAGINAW MADE
IT THE 8TH WETTEST (#1 5.36 IN 1897) JANUARY THERE. THE GREATEST
DAILY RAINFALL TOTAL FOR THE MONTH WAS 0.92" IN FLINT AND 0.99" IN
SAGINAW, BOTH ON THE 29TH.

THE AVERAGE HIGH TEMPERATURE FOR THE FLINT AREA WAS 35.0 (16TH
WARMEST), AND +5.4 DEGREES ABOVE THE NORMAL VALUE OF 29.6. THE
AVERAGE HIGH IN SAGINAW WAS 34.0 (19TH WARMEST ON RECORD), +5.1
DEGREES ABOVE THE 28.9 DEGREE NORMAL. FLINT`S AVERAGE LOW FOR THE
MONTH WAS 18.8 (30TH WARMEST ON RECORD), +3.5 DEGREES ABOVE THE 15.3
DEGREE NORMAL. SIMILARLY, THE AVERAGE LOW IN SAGINAW WAS 19.6 (22ND
WARMEST ON RECORD), AND +4.0 ABOVE THE NORMAL OF 15.6 DEGREES. THE
AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF JANUARY IN FLINT WAS
26.9 (19TH WARMEST), A DEPARTURE OF +4.5 DEGREES FROM THE 22.4
DEGREE JANUARY NORMAL. FOR SAGINAW, IT WAS 26.8 (19TH WARMEST ON
RECORD), AND +4.6 ABOVE THE 22.2 DEGREE DECEMBER NORMAL.
