...FALL SEASON 2014 SUMMARY...

...SEPTEMBER WAS RELATIVELY MILD WITH BELOW NORMAL PRECIPITATION...

SEPTEMBER BEGAN QUITE WARM WITH HIGH TEMPERATURES IN THE 80S ON THE
FIRST FOUR DAYS AND A HIGH OF 91 ON THE 5TH BEFORE A STRONG COLD
FRONT SWEPT THROUGH THE AREA. THIS FRONT BROUGHT SEVERAL INCHES OF
BENEFICIAL RAINFALL TO THE REGION WITH OVER AN INCH FALLING AT SOUTH
BEND. SEVERE WEATHER ALSO OCCURRED WITH THUNDERSTORMS PRODUCING
LARGE HAIL AND DAMAGING WINDS IN A FEW LOCATIONS.

THE AVERAGE MONTHLY TEMPERATURE WAS 63.2 DEGREES...0.7 DEGREES BELOW
NORMAL. THIS RANKED AS THE T-39TH COOLEST SEPTEMBER ON RECORD. THE
HIGHEST TEMPERATURE WAS 91 ON THE 5TH AND THE COOLEST WAS 40 ON THE
22ND. TOTAL PRECIPITATION WAS 2.71 INCHES...0.82 INCHES BELOW
NORMAL. THIS RANKED AS THE T-47TH DRIEST SEPTEMBER ON RECORD. THE
GREATEST 24 HOUR RAINFALL WAS 1.14 INCHES ON THE 5TH AND 6TH. A
TOTAL OF 11 DAYS IN SEPTEMBER HAD MEASURABLE PRECIPITATION AND TWO
OF THESE DAYS HAD GREATER THAN ONE HALF INCH OF RAINFALL.

...A SLIGHTLY WARM BUT WET OCTOBER IN SOUTH BEND AREA...

THE AVERAGE MONTHLY TEMPERATURE WAS JUST SLIGHTLY WARMER THAN NORMAL
IN THE SOUTH BEND AREA BUT PRECIPITATION WAS WELL ABOVE NORMAL. AS
WITH MANY OCTOBER MONTHS...TEMPERATURES FLUCTUATED SIGNIFICANTLY
WITH HIGHS RANGING FROM THE UPPER 70S TO MIDDLE 40S AND LOW
TEMPERATURES RANGING FROM THE LOWER 60S TO LOWER 30S. THE MONTH
ENDED WITH THE FIRST MEASURABLE SNOWFALL OF THE SEASON ON HALLOWEEN.

THE AVERAGE MONTHLY TEMPERATURE AT SOUTH BEND WAS 52.4
DEGREES...JUST 0.3 DEGREES ABOVE NORMAL. THIS RANKED AS THE 50TH
COOLEST OCTOBER ON RECORD DATING BACK TO 1894. THE HIGHEST
TEMPERATURE WAS 77 ON THE 2ND AND THE COLDEST TEMPERATURE WAS 30 ON
THE 22ND AND 23RD. THE DAILY AVERAGE TEMPERATURE WAS BELOW NORMAL ON
16 DAYS AND ONLY ONE DAY...THE 4TH...HAD AN AVERAGE TEMPERATURE MORE
THAN 10 DEGREES BELOW NORMAL (13 DEGREES BELOW NORMAL). THERE WERE FOUR
DAYS WITH AN AVERAGE DAILY TEMPERATURE OF TEN OR MORE DEGREES ABOVE
NORMAL. THE 27TH WAS THE WARMEST DAY WITH REGARDS TO DEPARTURE FROM
NORMAL AS THE AVERAGE DAILY TEMPERATURE ON THIS DAY WAS 13 DEGREES
ABOVE NORMAL.

PRECIPITATION FOR THE MONTH WAS 5.68 INCHES...2.36 INCHES ABOVE
NORMAL. THIS RANKED AS THE 10TH WETTEST OCTOBER ON RECORD.
MEASURABLE PRECIPITATION FELL ON 14 DAYS AND 2 DAYS HAD MORE THAN AN
INCH OF PRECIPITATION...THE SECOND AND THE THIRD OF THE MONTH. AS A
MATTER OF FACT...3.83 INCHES OF RAIN FELL ON THESE TWO DAYS. THAT
WAS NEARLY 70 PERCENT OF THE MONTHLY TOTAL.

THE MONTH ENDED WITH A STRONG COLD FRONT BLASTING THROUGH THE
REGION. TEMPERATURES FELL FROM THE 40S INTO THE 30S ON HALLOWEEN
DAY. RAIN SHOWERS TURNED TO SNOW SHOWERS WITH SEVERAL LOCATIONS
RECEIVING THEIR FIRST MEASURABLE SNOWFALL OF THE SEASON. AMOUNTS
WERE GENERALLY A HALF INCH OR LESS AND CONFINED TO GRASSY SURFACES.
SOUTH BEND OFFICIALLY REPORTED TWO TENTHS OF AN INCH. THIS WAS THE
4TH SNOWIEST HALLOWEEN ON RECORD AND THE 29TH SNOWIEST OCTOBER.

...A COLD AND SNOWY NOVEMBER...

IT WAS A COLD NOVEMBER WITH ABOVE NORMAL SNOWFALL IN THE SOUTH BEND
AREA. SEVERAL ROUNDS OF LAKE EFFECT SNOW WERE RESPONSIBLE FOR MOST
OF THE ACCUMULATIONS IN SOUTH BEND...WITH ONE SINGLE EVENT DROPPING
A FOOT OF SNOW ON THE CITY. THIS LAKE EFFECT WAS CAUSED BY THE
INTRUSION OF VERY COLD ARCTIC AIR OVER THE RELATIVELY WARM WATERS OF
LAKE MICHIGAN. THIS COMBINATION IN NOVEMBER CAN PRODUCE VERY INTENSE
LAKE EFFECT SNOW BANDS. DESPITE THE COLD AND SNOW...THERE WERE BRIEF
PERIODS OF WARMTH DURING THE MONTH...INCLUDING THE FIRST WEEK WITH
TEMPERATURES IN THE 60S AND THE LAST TWO DAYS WHEN HIGHS REACHED THE
MIDDLE AND UPPER 50S.

THE AVERAGE MONTHLY TEMPERATURE FOR NOVEMBER WAS 34.4 DEGREES...6.3
DEGREES BELOW NORMAL. THIS RANKED AS THE 6TH COLDEST NOVEMBER ON
RECORD IN THE SOUTH BEND AREA. THE HIGHEST TEMPERATURE DURING THE
MONTH WAS 63 ON THE 3RD AND THE COLDEST WAS 10 ON THE 15TH AND 18TH.
THE MIDDLE OF THE MONTH SAW A STRETCH OF VERY COLD TEMPERATURES WITH
THE FIRST ARCTIC BLAST OF THE SEASON. THE REMNANTS OF SUPER TYPHOON
NURI MOVED OUT OF THE PACIFIC OCEAN AND INTO THE BERING SEA BY THE
THE SECOND WEEK OF NOVEMBER. THIS STORM SYSTEM THEN HELPED PUSH AN
ARCTIC COLD FRONT INTO THE UNITED STATES WHICH BROUGHT SUBFREEZING
TEMPERATURES TO EVERY STATE BY THE MIDDLE OF THE MONTH.
LOCALLY...TEMPERATURES PLUNGED TO RECORD LEVELS WITH AVERAGE
TEMPERATURES BETWEEN 10 AND 25 DEGREES BELOW NORMAL FOR 10 STRAIGHT
DAYS BETWEEN THE 12TH AND 21ST. THE COLDEST DAY WAS THE 18TH WITH A
HIGH OF ONLY 18 AND A LOW OF 10. THE AVERAGE TEMPERATURE ON THIS DAY
WAS JUST 14...A WHOPPING 26 DEGREES BELOW NORMAL. THE HIGH OF 18
ALSO SET A RECORD FOR THE COLDEST HIGH TEMPERATURE ON THIS
DATE...BREAKING THE OLD RECORD OF 26 SET IN 1951.

PRECIPITATION FOR NOVEMBER WAS 3.37 INCHES...JUST 0.10 INCHES ABOVE
NORMAL. THIS RANKED AS ONLY THE 38TH WETTEST NOVEMBER ON RECORD.
ABOUT ONE THIRD OF THIS PRECIPITATION OCCURRED ON JUST ONE
DAY...NOVEMBER 23RD WHEN 1.24 INCHES OF RAIN FELL. THIS WAS A DAILY
RECORD FOR THAT DATE. THE ENTIRE RAIN EVENT PRODUCED 1.84 INCHES
OVER THREE DAYS...OVER HALF OF THE ENTIRE MONTHLY TOTAL.

DESPITE PRECIPITATION BEING NEAR NORMAL...SNOWFALL WAS WELL ABOVE
NORMAL. THERE WAS 19.1 INCHES OF SNOW RECORDED...14.3 INCHES
ABOVE NORMAL. THIS RANKED AS THE 4TH SNOWIEST NOVEMBER ON RECORD.
DECEMBER 1977 WAS THE SNOWIEST WITH 30.3 INCHES. WEATHER OBSERVERS
REPORTED 12.3 INCHES ON THE 13TH...A SINGLE DAY SNOWFALL RECORD FOR
THAT DATE AND THE 4TH HIGHEST DAILY SNOWFALL TOTAL FOR THE SOUTH
