Agriculture Increase in length of growing season for crops Increase rain in farming regions produces better crops Increase in temperature has caused oxygen levels in cold water streams to decrease More difficult for trout Flourishing Farmland Current Wisconsin Climate • The average U.S. temperature in September was 66.9 degrees F (19.4 degrees C), which is 1.5 degrees F (0.8 degrees C) above the long-term (1901-2000) average. • Precipitation, averaged across the nation, was 2.43 inches (61.7 2 mm). This was 0.10 inch (1.15 mm) below the long-term average, with large variability between regions. Wisconsin Monthly Temperature for the last 12 months Current Wisconsin Weather • September 2011 started off where summer left off - hot. A heat wave the first three days of the month set record maximum temperatures across the region, with a number of locations reaching maximums in excess of 100 degrees F (38 degrees C). Temperatures the first three days of September were well above normal across the entire Midwest, with departures from 9 degrees F to 14 degrees F (5 degrees C to 7.8 degrees C) above normal from Missouri east-northeast to Ohio. However, that was the last of the unseasonably warm weather for most of the region. Current Weather Continued Temperatures the remainder of September were 4 degrees F to 5 degrees F (2.2 degrees C to 2.8 degrees C) below normal across the central Midwest, dropping to near normal on the periphery of the region from northern Minnesota around to eastern Ohio. This same pattern was reflected at the end of the month, with average daily temperatures for September ranging from 2 degrees F to 4 degrees F (1.1 degrees C to 2.2 degrees C) below normal in the central Midwest, and near normal across most of Minnesota, northern Wisconsin, Michigan, and Ohio. Wisconsin Statewide Precipitation over the last 12 months Current Weather Continued For most of September it was dry across the Midwest, with the exception of along and south of the Ohio River. That changed the last ten days of the month, when an upper level low stalled over the southern Great Lakes and brought frequent and sometimes heavy rain to the eastern half of the region. Precipitation the last ten days of the month was 200 to more than 400 percent of normal from Wisconsin and Illinois eastward. For the entire month, precipitation was normal to 300 percent of normal from eastern Wisconsin and Illinois east through Ohio and Kentucky. 2011 Precipitation Visual Future Wisconsin Climate Much more drastic than what we have experienced so far. Average temperature to increase by as much as 4-9 degrees Fahrenheit by the middle of this century. Compared to only 1 degree increase so far. So does this mean no more snow?! No…but here are some Changes in store for the Future… Higher frequency of hot summer days Winters will continue current trend of warming more than any other season More rain and freezing rain Snow depth and cover will decrease drastically Future Weather Continued Continued trend of higher volume yielding precipitation storms Scientists at UW-Madison predict 25% increase in storms that produce 2 in. of precipitation or more by mid century In conclusion… Overall we won’t feel the extreme effects that climates closer to the equator will in regards to extreme heat Will see changes in our seasons o Longer summers o Short warm winters Bibliography http://www.aos.wisc.edu http://www.ncdc.noaa.gov/sotc/ http://www.ncdc.noaa.gov http://www.ncdc.noaa.gov www.wicci.wisc.edu THE END!
