==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - MARCH 2009
...BUSY STORM TRACK BRINGS ANOTHER BUSY MONTH BUT THIS TIME A RATHER
SNOWLESS MONTH...
...SCATTERED FLOODING RETURNS EARLY-MID MARCH...
...17TH WETTEST MARCH ON RECORD AT FLINT BUT 7TH SNOWLESS...
...TEMPERATURES CYCLED ROUTINELY FROM BELOW NORMAL TO ABOVE BUT AT
MONTH`S END...AVERAGED ABOVE...
***DOMINANT TEMPERATURE/RAIN TREND...NEAR NORMAL/ABOVE NORMAL***
SOUTHEAST LOWER MICHIGAN SAW ANOTHER WET MONTH IN MARCH WITH FREQUENT BOUTS
OF STORMY WEATHER MOVING THROUGH THE REGION. AFTER SUCH A STORMY AND SNOWY
WINTER...MARCH DID A COMPLETE ABOUT-FACE ON THE SNOW SIDE OF THINGS. IN
FACT...ONLY A LITTLE SPOTTY LIGHT SNOW WAS RECORDED UNTIL VERY LATE IN
THE MONTH /29TH/ WHEN A MORE WIDESPREAD INCH WAS SEEN. OFFICIALLY AT
FLINT BISHOP AIRPORT...1.1" OF SNOW WAS RECORDED (WITH 2.2" FOR MARCH)
...WHILE SAGINAW SAW ONLY 0.6" (0.7" FOR MARCH). VERY LITTLE SNOW IN
MARCH IS ACTUALLY HIGHLY UNUSUAL WITH A TRACE OF SNOW BEING THE LOWEST
/1945/.
THE MONTH STARTED ON A FRIGID NOTE WITH TEMPERATURES AVERAGING SOME
15 DEGREES BELOW NORMAL. IT WAS AT THIS TIME THAT THE LOWS OF THE MONTH
WERE ATTAINED WITH 6/5 AND 5/5 ON THE 2ND/3RD AT FLINT AND SAGINAW.
QUICKLY ON THE HEELS OF THE COLD SPELL CAME THE WARMTH WITH TEMPERATURES
SURGING UP INTO THE 50S AND 60S. AFTER THE LOW OF 5 ABOVE ON THE 3RD...
TEMPERATURES ROSE OVER SIXTY DEGREES TO 67 ON THE 6TH.
HEAVY RAINS THAT FELL ON THE 7TH-11TH BROUGHT GENERALLY AN INCH OR TWO
OF RAIN ACROSS THE FLINT AREA INTO SAGINAW AND THUMB REGION. THIS IN TURN
BROUGHT ANOTHER ROUND OF SCATTERED RIVER FLOODING TO THE REGION (BUT NOT
AS BAD AS FEBRUARY). FLOOD WARNING WERE ISSUED FOR THE SAGINAW AND CASS
RIVER BASINS.
WELL IT MIGHT HAVE BEEN THE "LUCK OF THE IRISH" OR JUST COINCIDENCE
BUT THE WARMEST DAY OF THE MONTH ARRIVED ON ST PATRICK`S DAY. SUNNY
SKIES AND BALMY WINDS CAUSED TEMPERATURE TO FLIRT WITH 70 DEGREES
ON THE 17TH WHEN IT REACHED 68 DEGREES AT BOTH FLINT AND SAGINAW.
OF COURSE...A BRIEF COLD SNAP (THOUGH A SUNNY DAY) ARRIVED IN TIME FOR
THE OFFICIAL FIRST DAY OF SPRING /20TH/ WITH TEMPERATURES ONLY RISING
TO AROUND 40. THE REST OF THE MONTH SAW NORMAL TO ABOVE NORMAL
TEMPERATURES WHICH LED TO A MONTHLY AVERAGE OF 35.4 AT FLINT AND
35.0 AT SAGINAW...BOTH NEAR TWO DEGREES ABOVE NORMAL.
ANALOGUES FOR THE SPRING INDICATED A BETTER CHANCE THAT MARCH AND APRIL
WOULD AVERAGE BELOW NORMAL... AND THOUGH THERE WERE SOME GOOD COLD
SNAPS...MARCH BUCKED THAT TREND...WILL APRIL?
