  • 2006 Ranks as 9th Warmest Year for Illinois

    "Based on preliminary data, temperatures of 54.0°F statewide (1.8°F above 30-year normals) made 2006 the 9th warmest year in Illinoissince 1895. This was largely the result of a record-setting January last year with an average temperature of 37.9°F, 13.3°F above normal," said State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • January Was Warmer, Wetter than Usual

    "Despite the recent cold spell, statewide January temperatures of 29.5°F were 4.7°F above normal, and precipitation of 3 inches was 1.07 inches above normal, based on preliminary data. Temperatures were well above normal the first half of January (12.7°F above) and slightly below normal the second half (2.8°F below), the third consecutive month with above normal temperatures. November–January temperatures were 4.2°F above normal, the 7th warmest such period on record since 1895," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • Snowy, Wet February, 9th Coldest on Record

    "Old Man Winter weather arrived in full force across much of Illinois in February, the 9th coldest on record since 1895, with a statewide temperature of 21.9°F, 8.9°F below normal, based on preliminary data. Snowfall generally was 2–6 inches (southern Illinois), 6–25 inches (central Illinois), and 12–25 inches (northern Illinois). Heaviest amounts occurred in east-central Illinois, with Sidell (Champaign County) reporting 27.5 inches, the most for any Illinois station.

  • Sixth Warmest March on Record

    "After a cold February, the pendulum swung the other way, giving Illinois March temperatures averaging 47.6°F statewide, 6.5°F above normal and the 6th warmest March on record since 1895. Several cities, particularly Champaign-Urbana, set or tied daily high temperature records," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • Cool, Wet Weather Slows Northern and Central Illinois Planting

    "Combined with cooler temperatures, wet April conditions led to widespread corn planting delays in the northern two-thirds of the state, where precipitation averaged 4.05 inches (0.46 inches above normal) and up to 5–7 inches at some locations. April temperatures averaged 49.5°F statewide (2.7°F below normal), and statewide precipitation was 3.75 inches (just 0.05 inches below normal), based on preliminary data. Southern Illinois was drier, averaging 3.38 inches (0.74 inches below normal), and planting there is further along," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • Very Dry May, 8th Warmest on Record

    "May 2007 was the 8th warmest and 23rd driest May since 1895. Statewide May precipitation in Illinois was 2.62 inches (1.65 inches below normal), and statewide temperatures were 67.3°F degrees (4.5°F above normal). Fortunately, short-term impacts of the dry weather were minimal because of abundant soil moisture from rainfall in previous months. Timely and widespread rains across northern and central Illinois over the Memorial Day weekend also provided relief for shallow-rooted corn and soybeans in those areas," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • High-density Network Measures Incredible Differences in Recent Heavy C-U Rains

    A high-density raingage network identified large differences in rainfall amounts from June 26-27 storms across Champaign County, Illinois. Amounts ranged from 2.58 inches just west of the I-57/I-72 interchange (west of Champaign) to less than 0.20 inch (southeast Urbana).

  • End-of-June Rainfall Provides Remarkable Transformation

    "The most outstanding feature of June weather was the change from very dry conditions the first 18 days to very wet ones the rest of the month. As a result, crops, lawns, and gardens recovered quickly from abnormally dry conditions that began in May," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources. Statewide June precipitation in Illinois was 4.47 inches (0.39 inches above normal), and statewide temperatures were 72.7°F degrees (0.8°F above normal). "That's quite a switch from the first 18 days of June, only 1.03 inches statewide, less than half the 2.42-inch normal for that period. The last 12 days of June had 3.44 inches, about twice the 1.66-inch normal," says Angel.

  • Cooler than Normal July Prevails

    "Statewide July temperatures averaged 73.5°F, 2.3°F below normal, and the 20th coolest July since 1895. While we had some hot days, Illinois generally managed to avoid the heat wave experienced out West during July," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

As of the morning of August 24, rainfall for northeastern Illinois (including those counties from Boone to LaSalle and eastward) averaged 11.32 inches, 8.10 inches above normal, and beating the 1987 record of 11.02 inches. Totals for JuneAugust thus far in this area averaged 20.02 inches, 8.91 inches above normal, and beating the 1972 record of 19.26 inches," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

Its JuneAugust total was 19.18 inches, 6.69 inches above normal and the 4th wettest on record," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

Temperatures in Illinois averaged 69.8 degrees, 3.6 degrees above normal, and the 15th warmest September on record," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.
