The most recent National Climate Assessment examined the pattern of increased rainfall across the Midwest. They state that Key Message #5 that "Extreme rainfall events and flooding have increased during the last century, and these trends are expected to continue, causing erosion, decline water quality, and negative impacts on transporation. The percentage of land area experiencing much greater than normal yearly precipitation totals increased between and There has been much year-to-year variability, however. In some years there were no abnormally wet areas, while a few others had abnormally high precipitation totals over 10 percent or more of the contiguous 48 states. Precipitation is moisture falling to the ground in the form of rain, snow or ice. Mountains have two major effects called the orographic effect, which causes clouds and precipitation to form on one side of the mountain, and the rain shadow effect, which is a drier area on the opposite side of the mountain. Cloud. Missing values are not included in the precipitation totals; therefore, the totals shown may be less than the actual amounts. Some data collected during cold weather may be affected by snow, and errors in water-equivalent values may result. More information about the quality of real-time data is available.

High-resolution precipitation maps based on National Weather Service radar-estimated precipitation, adjusted using available rain gauge data. This results in 4 km (or mile) resolution maps of precipitation. These are typically updated by p.m. each day for conditions through this morning. The tables below give yearly averages for rainfall plus snowfall at cities in Illinois. Each place has a total for the amount of precipitation it usually receives in a year. Most locations also have information on the number of days with wet weather. This includes the days when precipitation amounts to inches ( millimetres) or more.

What causes precipitation (rain and snow)? Precipitation forms when cloud droplets (or ice particles) in clouds grow and combine to become so large that their fall speed exceeds the updraft speed in the cloud, and they then fall out of the cloud. If these large water drops or ice particles do not re-evaporate as they fall farther below the cloud, they reach the ground as precipitation. The weather here in Southern Illinois is more stable and mild than the majority of Illinois which makes the Shawnee Forest, the Shawnee Hills Wine Trail, and other major tourist attractions in this region the perfect vacation from the harsh winters found in Central and Northern Illinois. Southern Illinois Climate . Hatching represents areas where the majority of climate models indicate a statistically significant change. Spring precipitation in Illinois is projected to increase in the range of 10–20% by These increases are part of a large area of projected increases across the northern United States. Source: CICS-NC, NOAA NCEI, and NEMAC. Southern Illinois (also known as "Little Egypt") is the southern third of the state of southern part of Illinois has a unique cultural and regional history. Part of downstate Illinois, the Southern Illinois region is bordered by the two most voluminous rivers in the United States: the Mississippi River and its connecting Missouri River to the west, and the Ohio River to the east.
