...Another round of thunderstorms expected Friday afternoon and Friday night...

ESFLOT

Additional thunderstorms are expected Friday afternoon and Friday
night across northern Illinois and northwest Indiana. Atmospheric
conditions are favorable for some of these storms to produce
locally heavy rainfall.

Many rivers across northern Illinois and northwest Indiana remain
elevated. Soil moisture also remains elevated in many areas,
especially in northern Illinois along the Wisconsin border. Thus,
any heavy rainfall that occurs could lead to flooding of rivers,
creeks, urban and low-lying areas. Rivers such as the Rock, Fox
and Des Plaines which are already in flood in some locations, may
be especially prone to rainfall which could exacerbate ongoing
flooding.

This outlook means that elevated water levels and potential
impacts are possible, but not yet certain. Persons should closely
monitor forecasts including the possibility of flood watches,
warnings, and advisories.

This outlook will be updated by Friday afternoon.
