The Weather Front On-Line
High temperatures approaching 100 degrees have many people wondering about the last time this occurred. Reaching 100 degrees is a rare occurrence in central Illinois. A review of the climate record shows it has been at least several years since most locations have reached triple digits. The Champaign-Urbana area went 16 years without reaching the century mark, until a high of
Statewide temperatures were a bit above normal last week. Precipitation a bit below normal. The far southern districts of the state received over one inch of rain. Northern areas, however, were again below average in rainfall.
Topsoil moisture was rated 9 percent very short, 29 percent short, 54 percent adequate and 8 percent surplus.
A dangerous combination of heat and humidity continues!
An expansive area of upper level high pressure will intensify over the middle of the Nation. This will bring a return to oppressive heat and humidity, beginning this weekend. Conditions appear similar to the most recent heat wave, except over a much longer time frame.
For the remainder of the week, a stubborn ridge of high pressure will maintain hot, dry conditions across the drought-ravaged south-central U.S. However, tropical moisture will continue to wrap clockwise around the ridge, with heavy, “ring of fire” showers possible. A cold front crossing the northern half of the U.S. will further enhance rainfall in some areas.
Across the Corn Belt, strong thunderstorms in the vicinity of a cold front are crossing northern and western portions of the region. Meanwhile, the winter wheat harvest is advancing across the southern and eastern Corn Belt under a hot weather regime.
Locally, high pressure will hold across the region Saturday and shift east Sunday, resulting in a partly to mostly sunny sky and seasonably warm temperatures. Quiet weather is expected into Sunday before a weak cold front slowly approaches from the northwest Sunday night or Monday. Temperatures will gradually warm, with afternoon readings climbing back to or a few degrees above 90 degrees.
Across the Corn Belt, mild weather, scattered showers, and abundant soil moisture reserves continue to provide a nearly ideal environment for developing corn and soybeans. Meanwhile, the Midwestern soft red winter wheat harvest is advancing as conditions permit.
