.DISCUSSION...
Isolated morning thunderstorms will become more numerous from
west to east from late morning through midday and into this
afternoon. Strong to severe storms will be possible, especially
along and east of the I-55 corridor from northern Illinois into
Indiana this afternoon. Damaging wind gusts are the main severe
weather threat, though hail and even tornadoes are possible. Some
storms may also produce torrential rainfall which could lead to
localized flooding. The severe threat should end by evening,
though scattered showers and a few isolated storms may persist
overnight into Thursday morning.
Mainly dry weather is expected from Thursday afternoon through
the weekend, though there is a slight (less than 20 percent)
chance that isolated strong thunderstorms over southeast Wisconsin
cloud briefly clip far northeast Illinois Thursday afternoon and
early evening and again Friday afternoon. Otherwise, hot and humid
weather will build into the area this weekend and into early next
week. Daytime highs in the mid 90s and peak heat indices at or
above 100 degrees are likely.
