Michigan, Michigan gets 34 inches of rain, on average, per year. The US average is 38 inches of rain per year.

The rainfall totals so far this year look especially erratic. Some areas are pacing much higher than average on yearly rainfall. A few other areas are lacking a significant amount of rain in these first nine months of The splotches of orange around Grand Rapids, the northwest Detroit suburbs and west of Marquette are the areas of heaviest rain this year. Those orange areas have had over 35 inches of moisture so far in

Michigan annual rainfall

Note how, as distance from the moisture source Gulf of Mexico and the Atlantic increases, precipitation decreases. Annual mean precipitation ranges from a maximum of more than 36 inches in the southwestern Lower Peninsula to a minimum of fewer than 27 inches in the northeastern Lower Peninsula. These variations result primarily from statewide differences in the availability of moisture-laden air associated with passing fronts and cyclonic storms. The lower precipitation amounts in the north reflect a northward decrease in the amount of water vapor present in the atmosphere that can interact with these disturbances. Air masses acquire water vapor through transpiration by plants, evaporation from the soil, and most important, directly from bodies of water. Large amounts of moisture, however, can be acquired only from warm-water bodies such as tropical oceans. Thus, the Great Lakes supply only a small percentage of the total water that falls as rain or snow in the state; most of it originates in tropical air masses that move north from the Gulf of Mexico. Since these air masses originate in areas far south of Michigan, they most often reach only the southern Lower Peninsula before being driven out by a passing disturbance. Hence, average annual precipitation is highest in this area and decreases to the north. Only in these lake-effect snow areas is the contribution of moisture from the Great Lakes important, elsewhere, the primary source of moisture is the tropical air masses. Local differences in annual mean precipitation are related to either the Great Lakes or to elevation. Cooler lake breezes advancing inland off the Great Lakes during warm summer afternoons may destroy or weaken some thundershowers in the coastal areas.

The map below, which shows a series of climagraphs for the Great Lakes region, clearly makes several points: 1. The radar estimates are quite accurate, but could be an inch off, michigan annual rainfall. Large amounts of moisture, however, can be acquired only from warm-water bodies such as tropical oceans.

Historically unprecedented warming is projected during this century. Extreme heat is a particular concern for densely populated urban areas such as Detroit, where high temperatures and high humidity can cause dangerous conditions. Projected increases in winter and spring precipitation raise the risk of springtime flooding, which could delay planting and reduce yields. Changes in seasonal and multiyear precipitation and increased evaporation rates due to rising temperatures can affect water levels in the Great Lakes, causing serious environmental and socioeconomic impacts. Michigan experiences large seasonal changes in temperature, with warm, humid summers and cold winters.

Climate in Michigan is comprised of many factors that impact our communities, schools, and businesses over time.

Climate and monthly weather forecast Michigan, USA. Expand Contents. Flag of Michigan, USA. Lake Michigan and Wisconsin in the southwest to the northwest, Lake Superior and Lake Huron in the north to northeast, Lake Erie in the southeast, and Ohio and Indiana in the south form the borders of the state. The latitude, altitude, and proximity to the Great Lakes influence the climate of Michigan to a large extent. Michigan, the Great Lakes State, is home to the longest freshwater coastline in the world, with four great lakes, and over 11, small lakes in its tow. The state consists of an Upper and a Lower Peninsula, with different versions of a continental climate, joined by the Straits of Mackinac. The topography consists of flatlands and gently rolling hills in the eastern half of the Upper Peninsula, while the western tablelands rise to meters.

Sommers' book entitled, " Michigan: A Geography ". Michigan averages 9. Virgin Islands. Increases in precipitation are projected for Michigan, most likely during the winter and spring Figure 5. Lower lake levels were observed in the s and s and again in the s. Northern Lower Michigan and the Upper Peninsula averages 22 inches to 25 inches through late September. Look at the map below, of average wintertime precipitation. It also shows that the UP is essentially "wetter" than the lower peninsula, even though the latter gets more precipitation in many parts. Climagraphs are a useful way of examining annual and monthly patterns of precipitation. Cooler lake breezes advancing inland off the Great Lakes during warm summer afternoons may destroy or weaken some thundershowers in the coastal areas. The map below, which shows a series of climagraphs for the Great Lakes region, clearly makes several points: 1. The horizontal black lines show the long-term entire period averages: a 8. Champion, and J.

Historically unprecedented warming is projected during this century. Extreme heat is a particular concern for densely populated urban areas such as Detroit, where high temperatures and high humidity can cause dangerous conditions.

Projected increases in winter and spring precipitation raise the risk of springtime flooding, which could delay planting and reduce yields. In general, wintertime precipitation is closely associated with the lakes--dry on the windward sides and wet on the lee sides. Virgin Islands. The year was the hottest on record, with a statewide annual average temperature of The most humid months but still comfortable are July, August and June. One copy may be printed for personal use. Summer High: the July high is around 81 degrees Winter Low: the January low is 14 Rain: averages 34 inches of rain a year Snow: averages 64 inches of snow a year. Michigan averages 64 inches of snow per year. The unshaded areas are just an inch or so either side of normal and what I would call near normal. While there are large areas of wetter-than-normal weather, there are also two areas that are very dry. Repeated often enough, this process results in a somewhat lower amount of summertime precipitation than in the inlands areas, which are unaffected by normal lake-breeze pattens. Temperatures in the s have been higher than in any other historical period.
