STATE CLIMATOLOGY OFFICE - DNR WATERS --- FOR IMMEDIATE RELEASE
SEPTEMBER 30, 2005
Subject: Warm and wet September in the Twin Cities.
For the Twin Cities, September 2005 was more an extension of summer
than the beginning than fall. There were plenty of warm temperatures,
including a 90 degree maximum on September 10. If the forecast for
Friday, September 30 for the Twin Cities holds true, September 2005
will finish at 66.4 degrees. That is 5.9 degrees above the normal mean of
60.5 and the 11th warmest September on record. Chilly Septembers have been
a rarity in recent years. The past three Septembers were well above normal
(67.4 in 2004, 62.5 in 2003, 65.5 in 2002).
Does a mild October follow a warm September? In the previous three Septembers,
two Octobers were warmer than normal and one was much colder than normal.
Looking at the ten warmest Septembers on record, eight of the following
Octobers were warmer than normal and only two were cooler than normal.
The summer-like severe weather on September 21 was arguably the most
widespread severe weather event to hit the Twin Cities since May 1998.
September was also a wet month across the Twin Cities as well as most
of Minnesota. At the Twin Cities International Airport, the month
finished with 4.44 inches of rain, 1.75 inches above normal. Parts of
the northern and western metro area received more rain for the month,
including an even ten inches in Fridley and 9.85 inches in Chanhassen.
Some places in southern Sherburne County and northeast Wright County
received 11 inches of rain for the month.
