==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - FEBRUARY 2009
...LAST OFFICIAL WINTER MONTH MODERATES IN BOTH TEMPERATURES AND
SNOWFALL...
...EXTREME TEMPERATURE RANGE OF 78 DEGREES THIS MONTH AT FLINT...
...RAPID SNOWMELT AND HEAVY RAINS INDUCE FLOODING ON LOCAL RIVERS...
***DOMINANT TEMPERATURE/SNOW TREND...ABOVE NORMAL/NORMAL***
THERE WAS A NOTABLE DIFFERENCE IN THE UPPER AND SURFACE WIND PATTERNS
OF FEBRUARY. THE ARCTIC AIR SURGES PREVALENT THE LAST FEW MONTHS
WERE CUT OFF AT TIMES AND MILDER AIR FLOODED THE REGION FROM THE
PACIFIC OR GULF REGION. THIS LED TO FEBRUARY BEING NOT ONLY A MORE
MODERATE MONTH...BUT ALSO A MUCH MORE VARIABLE MONTH WITH SOME NOTABLE
WARM SNAPS CONTRASTING THE COLD SNAPS.
WHILE FEBRUARY STARTED OFF BRIEFLY MILD...ANOTHER SHOT OF BRUTAL ARCTIC
AIR SOON MADE ITS APPEARANCE BY THE END OF THE 2ND AND BY THE MORNING
OF THE 5TH...READINGS PLUNGED WELL BELOW ZERO. OFFICIALLY AT FLINT
BISHOP...THE TEMPERATURE WAS FELL TO -11 ON THE 4TH AND -18 ON THE
5TH....WHILE SAGINAW DROPPED TO -7 AND -11...RESPECTIVELY. IRONICALLY...
THE ONLY RECORD LOW ESTABLISHED WAS THE -18 ON THE 5TH AND THIS
BROKE THE OLD RECORD OF -8 SET IN 1974. THE ENTIRE REGION DID HAVE
EXCEPTIONAL COLD THAT MORNING /5TH/ WITH WIDESPREAD READINGS OF -10 TO
-20. THE COLDEST OF READINGS WERE... -24 AT BAD AXE...-20 FILION...-20
VASSAR...-17 LAPEER...-16 AT BOTH GOODRICH AND CARO.
A WELL DESERVED WARM UP FOLLOWED THIS PERIOD OF BITTER COLD AIR AS THE
JET STREAM SHIFTED TO A STRONG SOUTHWESTERLY FLOW WHILE DEVELOPING A
LARGE STORM CENTER OVER THE NORTHERN PLAINS. THIS STORM DREW VERY MILD
AIR FROM THE DEEP SOUTH NORTHWARD INTO THE LAKES. TEMPERATURES ROSE
STRONGLY INTO THE MID 50S TO AROUND 60 BY 10TH AND 11TH. THE WARMTH
BLEW AWAY AN OLD RECORD HIGH ON THE 10TH WITH A HIGH OF 60 /OLD RECORD
53-1996/ WHILE SAGINAW HIT 58 /OLD RECORD 52 IN 1966/. THE RANGE IN
TEMPERATURE AT FLINT IN THE FIVE DAYS FROM THE 5TH TO THE 10TH WAS
EXTRAORDINARY. FROM A LOW OF -18 ON THE 5TH TO A HIGH OF 60 ON THE
10TH...FLINT RANGED 78 DEGREES! ALONG WITH THE WARMTH CAME FLOODING
FROM RAPIDLY MELTING SNOW COVER AND HEAVY RAINS. FLOOD WARNINGS WERE
ISSUED FOR MANY RIVERS INCLUDING...THE CASS...SAGINAW...SHIAWASSEE...
TITTABAWASSEE AND KEARSLEY CREEK.
COLDER WEATHER ALONG WITH SNOW ARRIVED ON THE SCENE FOR VALENTINES DAY.
GENERALLY 1 TO 3 INCHES FELL WITH 2.4" AT FLINT AND 1.6" AT SAGINAW.
AFTER...TEMPERATURES GENERALLY AVERAGED AROUND NORMAL BUT BEGAN TO LOSE
GROUND AGAIN BY THE 23RD AND 24TH AS ANOTHER FAIRLY POTENT COLD SNAP
DROVE TEMPERATURES DOWN INTO THE SINGLE FIGURES. ANOTHER STORM PUSHED
THROUGH THE LAKES AHEAD OF THE COLD ON THE 21ST AND 22ND...AND BROUGHT
GENERALLY 3" TO 5" OF SNOW. HIGHEST AMOUNTS WERE 5.3" AT MIDLAND AND
5.0" AT HARBOR BEACH. ANOTHER WARM-UP ENSUED AT THE END OF THE MONTH
WITH TEMPERATURES SURGING BACK UP INTO THE 40S AND 50S...ONLY TO BE
SQUASHED ONE AGAIN AT THE TURN OF THE MONTH WITH A NEW COLD SNAP FOR
MARCH`S OPENING.
A FAIRLY ACTIVE STORM TRACK CONTINUED THROUGHOUT FEBRUARY WITH ABOVE
NORMAL PRECIPITATION AND AROUND NORMAL SNOWFALL DESPITE THE WARMER
TREND DOMINANCE. LOOK FOR A PRELIMINARY WINTER REVIEW (TEMPERATURES AND
SNOWFALL THUS FAR) AND SPRING OUTLOOK WITHIN THE NEXT WEEK ON LINE AT
OUR HOME PAGE WWW.WEATHER.GOV/DTX.
*********************************************************************
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.
