Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

2: Our Changing Climate).48, 190 Increases in both extreme precipitation and total precipitation have contributed to increases in severe flooding events in certain regionsIncreases in both extreme precipitation and total precipitation have contributed to increases in severe flooding events in certain regionsincreases in severe flooding events in certain regions (see Ch.

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 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 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 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 precipitation events is projected to continue in the future.80

In weather systems, convergence of increased water vapor leads to more intense precipitation and the risk of heavy rain and snow events, but may also lead to reductions in duration and / or frequency of rain events, given that total amounts do not change much.

Since 1895, the total annual precipitation has increased by about 6 inches, or 13 percent.
