The hot weather will continue across central and southeast Illinois into the first part of the weekend. Highs above 100 degrees are expected over central and southeast Illinois today. Heat index values may exceed 110 degrees at times. The arrival of a cold front from the north this weekend will finally break the heat wave, and highs over the entire area will be in the mid 80s by Monday.
The hot temperatures and drought conditions will continue to produce an enhanced fire risk. Many counties have initiated burn bans due to the tinder dry conditions. Use of fireworks may cause grass fires, especially in areas where little rain has fallen recently.
With summertime outdoor work and recreation activities, heat-related illnesses will be possible with extended outdoor exposure. Be familiar with heat wave safety guidelines, and recognizing the symptoms of heat exhaustion or heat stroke. Never leave children or pets in unattended vehicles, even for a short period of time, as temperatures inside vehicles can reach dangerous levels in a matter of minutes. Try to spend at least some time in an air-conditioned environment.
