Scientists expect more
intense storms to occur in the Midwest throughout the year, and more precipitation to fall in winter and spring.4 If our carbon emissions continue to rise at current rates, spring
rainfall in Jefferson City is projected to increase 25 percent or more by the end of this
century.9, 10
Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past
century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest
rainfalls.77, 78,79 This tendency towards more
intense precipitation events is projected to continue in the future.80
Although we can not say at present whether more or fewer hurricanes will occur in the future with global warming, the hurricanes that do occur near the end of the 21st
century are expected to be stronger and have significantly more
intense rainfall than under present day climate conditions.
We also conclude that it is likely that climate warming will cause Atlantic hurricanes in the coming
century have higher
rainfall rates than present - day hurricanes, and medium confidence that they will be more
intense (higher peak winds and lower central pressures) on average.
