...AN OVERALL WARM AND DRY FALL SEASON...

OVERALL THE 2010 FALL SEASON WAS WARMER AND DRIER THAN NORMAL AS A
LA NINA EPISODE WAS STRENGTHENING IN THE PACIFIC OCEAN. LA NINA IS A
PHASE OF THE EL NINO SOUTHERN OSCILLATION WHERE CENTRAL EQUATORIAL
PACIFIC OCEAN SEA SURFACE TEMPERATURES ARE BELOW NORMAL...WHICH HAS
A LARGE INFLUENCE ON WEATHER PATTERNS ACROSS NORTH AMERICA. TYPICAL
LA NINA CONDITIONS DURING THE LATE FALL AND WINTER MONTHS ACROSS THE
AREA INCLUDE ABOVE NORMAL TEMPERATURES AND ABOVE NORMAL
PRECIPITATION. THE VERY END OF THE FALL SEASON FINALLY SAW MUCH
NEEDED RAINFALL ACROSS MOST AREAS...A RESULT OF THE MODERATE TO
STRONG LA NINA. THIS HELPED BRING THE MONTHLY PRECIPITATION TOTAL AT
FORT WAYNE ABOVE NORMAL IN NOVEMBER...SOMETHING THAT HAD NOT
HAPPENED SINCE JUNE 2010.

EACH MONTH OF THE FALL SEASON EXPERIENCED ABOVE NORMAL TEMPERATURES
AT FORT WAYNE. OCTOBER HAD THE GREATEST DEPARTURE FROM NORMAL WITH
AN AVERAGE TEMPERATURE 2.7 DEGREES ABOVE NORMAL. SEPTEMBER AND
OCTOBER EACH HAD BELOW NORMAL PRECIPITATION WHILE NOVEMBER WAS ABOVE
NORMAL. OCTOBER WAS THE DRIEST MONTH WITH ONLY 0.58 INCHES OF
PRECIPITATION...2.05 INCHES BELOW NORMAL. THE LAST HALF OF NOVEMBER
WAS WET AND HELPED BRING THE NOVEMBER PRECIPITATION TOTAL TO 4.01
INCHES...1.03 INCHES ABOVE NORMAL.

SNOWFALL WAS BELOW NORMAL AT FORT WAYNE. DURING THE ENTIRE FALL
SEASON...ONLY A TRACE OF SNOWFALL WAS REPORTED. THIS IS THE SECOND
CONSECUTIVE FALL SEASON WITH NO MEASURABLE SNOWFALL. THIS TIES AS
THE LEAST SNOWIEST FALL SEASON ON RECORD WITH NO MEASURABLE
SNOWFALL. SINCE 2000...5 FALL SEASONS HAVE HAD NO MEASURABLE
SNOWFALL AT FORT WAYNE. THESE INCLUDE 2001...2006...2007...2009...2010.

THIS FALL SEASON ALSO HAD A SIGNIFICANT SEVERE WEATHER EVENT ON THE
26TH OF OCTOBER. THUNDERSTORMS WITH STRAIGHT LINE WINDS OF 60 TO 70
MPH OCCURRED ACROSS MUCH OF THE AREA. THERE WAS ALSO A LARGE
OUTBREAK OF TORNAOES ON THIS DAY WITH 13 CONFIRMED ACROSS NORTHERN
INDIANA AND NORTHWEST OHIO...INCLUDING IN THE IMMEDIATE FORT WAYNE
AREA.

DESPITE BEING RELATIVELY MILD AND QUITE DRY...THERE WERE NO TOP 10
RECORDS SET FOR PRECIPITATION OR AVERAGE TEMPERATURE AT FORT WAYNE.
