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.

Model projections for precipitation changes are less certain than those for temperature.12, 2 Under a higher emissions scenario (A2), global climate models (GCMs) project average winter and spring precipitation by late this century (2071 - 2099) to increase 10 % to 20 % relative to 1971 - 2000, while changes in summer and fall are not expected to be larger than natural variations.

Winters are shorter, fewer cold records are set, more precipitation is falling as rain and less as snow — although whopper snowstorms are even more likely in some places — and snowpacks are shrinking and melting earlier.

Most climates that have 20 inches of precipitation or less fall into this category.

Dry Climates A climate is dry if the amount of precipitation that falls is less than the amount that evaporates.

This is an important capability for predicting summer temperatures because observed daily temperatures are usually higher on rainless days and when precipitation falls less frequently than normal.

Therefore, less of a region's precipitation is likely to fall in light storms and more of it in heavy storms.
