Hazardous Weather Outlook For DUPAGE County,IL

416 AM CDT Sun Jun 24 2018 /516 AM EDT Sun Jun 24 2018/

 DAY ONE  Today and Tonight.

Many area rivers will remain in flood. 

 DAYS TWO THROUGH SEVEN  Monday through Saturday.

Monday Night  
  Limited Severe Thunderstorm Risk.
  Elevated Flooding Risk.
  High Swim Risk Illinois shores.
Tuesday  
  Elevated Severe Thunderstorm Risk Late Afternoon and Evening.
  Elevated Flooding Risk.
  High Swim Risk early Illinois shores.

Friday  
  Elevated Excessive Heat Risk.
Saturday  
  Limited Thunderstorm Risk.

DISCUSSION:

Two distinct rounds of thunderstorms will be possible. The first 
round will be Monday night into early Tuesday. Some of these
storms could be strong across western Illinois. Very heavy 
rainfall will also be possible with these storms. A second round 
of thunderstorms will then be possible late Tuesday afternoon and
evening. While this second round of storms will also be capable 
of producing heavy rain, there is also an increased threat that 
some of these storms will be capable of being severe, with strong
damaging winds and possibly some hail. 

Given the wet conditions of late and the possibility for more 
heavy rainfall, localized flash flooding will be possible Monday 
night through Tuesday night.

Temperatures and humidity levels will be on the increase later in
the week. This could result in heat indices climbing well into 
the 90s by Thursday and to 100 to 105 degrees Friday and Saturday.

In addition  many area rivers will remain in flood into early 
this week  though additional rises may be possible Tuesday into
Wednesday.
