[July 17, 2013]  The National Weather Service office in Lincoln released a special weather statement at 4:04 a.m. Wednesday saying that oppressive heat is expected to persist through Friday.

This statement is for the counties of Knox, Stark, Peoria, Marshall, Woodford, Fulton, Tazewell, McLean, Schuyler, Mason, Logan, DeWitt, Piatt, Champaign, Vermilion, Cass, Menard, Scott, Morgan, Sangamon, Christian, Macon, Moultrie, Douglas, Coles, Edgar, Shelby, Cumberland, Clark, Effingham, Jasper, Crawford, Clay, Richland and Lawrence, including the cities of Galesburg, Peoria, Bloomington, Normal, Havana, Lincoln, Champaign, Urbana, Danville, Jacksonville, Springfield, Taylorville, Decatur, Charleston, Mattoon, Shelbyville, Effingham, Flora and Lawrenceville.

Hot and humid weather will continue over the Midwest through the rest of the workweek, with an area of high pressure firmly entrenched over the region. Highs in the lower 90s will be common across central and southeast Illinois on Wednesday and Thursday, with afternoon heat index values near or just above 100 degrees. The peak of the heat wave will be on Friday, as highs reach the mid-90s and the heat index ranges from 100 to 105 degrees. Relief from the heat will begin to move in late Friday, as a cold front arrives from the northwest, bringing the threat for showers and thunderstorms to parts of the area, especially Friday night, followed by cooler and less humid weather for the weekend.

The combination of high temperatures and high humidity will create a situation in which heat illnesses are possible. The effects of heat are cumulative and will increase as the heat wave progresses.

To remain safe from the heat, try to be in air-conditioned environments as much as possible, drink plenty of fluids and stay out of the sun, especially during the heat of the day. Be sure to check up on relatives and neighbors, especially those who are elderly or in poor health.

Remember, children and pets should never be left unattended in vehicles under any circumstances. Vehicle temperatures can rapidly increase to lethal levels in a matter of minutes, even if the windows are cracked open. Nearly a third of all heat-related deaths each year are due to young children being left in enclosed vehicles.
