This Hazardous Weather Outlook is for central Illinois, east
central Illinois, southeast Illinois and west central Illinois.
.DAY ONE...Today and tonight.
A multi-day stretch of hot and humid weather will develop across
central Illinois today. High temperatures will warm into the low to
mid 90s this afternoon with heat indices peaking between 100 and 110
degrees.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
A multi-day stretch of hot and humid weather will continue through
at least early next week. High temperatures in the low to mid 90s,
low temperatures in the mid 70s, and afternoon heat indices of 100 to
105 degrees can be expected. The prolonged nature of the heat and
lack of nocturnal cooling will increase the risk for heat related
illness for those without effective cooling or hydration. The heat
may continue into midweek, however, there is some uncertainty due to
the increasing potential for showers and storms midweek as a slow
moving frontal system gradually shifts into the region.
