...JANUARY WAS LIKE A WEATHER ROLLER COASTER...

DRAMATIC UPS AND DOWNS IN TEMPERATURES DURING THE MONTH MADE IT FEEL
LIKE A WEATHER ROLLER COASTER. HIGH TEMPERATURES TOPPED OUT NEAR 60
DEGREES AND LOW TEMPERATURES BOTTOMED OUT AROUND ZERO DEGREES.
JANUARY ALSO SAW ABOVE NORMAL PRECIPITATION WITH A FEW DAYS OF
MODERATE TO HEAVY RAINFALL. THIS HELPED RAISE WATER LEVELS ON AREA
LAKES AND RIVERS AND EVEN LED TO SOME MINOR FLOODING.

THE ROLLER COASTER RIDE BEGAN WITH TEMPERATURES SLIGHTLY BELOW
NORMAL AND RELATIVELY DRY CONDITIONS TO START THE MONTH.
A JANUARY THAW OCCURRED DURING THE SECOND WEEK AS HIGHS CLIMBED INTO
THE 40S AND TOPPED OUT IN THE UPPER 50S ON JANUARY 12TH. THE HIGH ON
THIS DAY IN SOUTH BEND WAS 58. THIS WARM UP WAS ALSO ACCOMPANIED BY
OVER AN INCH OF MUCH NEEDED RAINFALL WHICH OCCURRED BETWEEN THE 10TH
AND 13TH. THIS WARM RESPITE WAS SHORT LIVED AS MORE SEASONABLE
TEMPERATURES RETURNED ON THE 13TH...FOLLOWED BY A MILD WARM UP ON
THE 19TH.

SNOWFALL THROUGH JANUARY 20TH WAS WELL BELOW NORMAL WITH ONLY THREE
TENTHS OF AN INCH BEING RECORDED. THE REMAINDER OF THE MONTH WAS A
DIFFERENT STORY AS THE FIRST SIGNIFICANT ARCTIC OUTBREAK OF THE
SEASON BROUGHT TEMPERATURES CRASHING TO THE SINGLE DIGITS BY THE
21ST. THE 22ND WAS THE COLDEST DAY OF THE WINTER SEASON SO FAR WITH
A HIGH OF ONLY 9 AND A LOW OF 3 IN SOUTH BEND. LAKE EFFECT SNOWFALL
KICKED IN AND SOUTH BEND RECEIVED OVER 7 INCHES OF SNOW BETWEEN THE
20TH AND 26TH WHILE SOME LOCATIONS IN LOWER MICHIGAN RECEIVED A FOOT
OR MORE.

ANOTHER SIGNIFICANT WARMING TREND BEGAN ON THE 27TH WITH
TEMPERATURES RECOVERING BACK TO NEAR 60 BY THE 29TH. A SECOND ARCTIC
RUSH QUICKLY FOLLOWED AS TEMPERATURES PLUMMETED INTO THE TEENS ON
THE 31ST. RAINFALL OF OVER TWO INCHES FELL AHEAD OF THIS ARCTIC COLD
FRONT AND LAKE EFFECT SNOWFALL OF OVER 4 INCHES FOLLOWED IN ITS
WAKE.

THE AVERAGE MONTHLY TEMPERATURE WAS 27.7 DEGREES...3.3 DEGREES ABOVE
NORMAL. THIS RANKS AS THE 34TH WARMEST JANUARY SINCE 1893. THE
HIGHEST TEMPERATURE FOR THE MONTH WAS 59 ON JANUARY 29TH. THIS WAS
THE WARMEST JANUARY TEMPERATURE SINCE JANUARY 7TH 2008 WHEN THE HIGH
WAS A BALMY 65 DEGREES. THE LOWEST TEMPERATURE WAS 3 ON THE 22ND.
THE LAST TIME SOUTH BEND WAS COLDER THAN THIS WAS ON FEBRUARY 11TH
2011 WHEN THE LOW WAS 2 DEGREES. THE LAST TIME THE TEMPERATURE WAS
BELOW ZERO IN SOUTH BEND WAS FEBRUARY 10TH 2011 WHEN THE LOW WAS
NINE DEGREES BELOW ZERO.

THE MONTHLY PRECIPITATION WAS 5.00 INCHES...2.71 INCHES ABOVE
NORMAL. THE GREATEST 24 HOUR PRECIPITATION WAS ON THE 29TH AND 30TH
WHEN 2.24 INCHES FELL. THE MONTH RANKS AS THE 5TH WETTEST ON RECORD.
THE 1.94 INCHES WHICH FELL ON THE 29TH BROKE A RECORD FOR THE DATE
AND WAS ALSO THE 4TH WETTEST JANUARY DAY ON RECORD. IT WAS ALSO THE
WETTEST JANUARY DAY SINCE 1967 WHEN 2.12 INCHES FELL ON JANUARY
26TH.

SNOWFALL FOR THE MONTH AT SOUTH BEND WAS OFFICIALLY 11.9
INCHES...8.7 INCHES BELOW NORMAL. THIS RANKS AS THE 43RD LOWEST
JANUARY SNOWFALL TOTAL SINCE 1893.
