Cold October Continues...

October 2009 is off to a very cool start over much of the Northern Plains, including much of South Dakota and west-central Minnesota.  In fact, at Pierre, the average temperature through the first 20 days of the month (Oct 1-20) is currently the coldest on record!  At Aberdeen and Watertown, average temperatures are currently the second coldest on record (see tables below). 

Current forecasts indicate the area will likely see a continuation of temperatures at or below normal through at least the next 7 days.
