Heavy rain producing thunderstorms are expected to develop once again late Wednesday evening, lasting into Thursday morning with potentially another inch of rain falling across northern Illinois.

Skies are quiet early this evening but thunderstorms are expected to increase in coverage, becoming more widespread across west-central Illinois by 10pm.  Those storms will quickly race northeast through the night impacting northern Illinois between 11pm and 5am Thursday morning.

Severe thunderstorms have developed just southwest of Cedar Rapids, IA Wednesday evening with a couple tornado warnings being issued.  There have also been a few reports of rotating wall clouds, funnel clouds and even a reported tornado.  I do not expect those storms to move in our direction tonight, however, some of the storms could produce strong winds and hail as they move through during the overnight.  Our greatest threat, however, will likely be heavy rain that will last through about 4am Thursday morning.

As a cold front passes Thursday afternoon the redevelopment of showers and thunderstorms will be possible through early evening.  Drier air moves in behind the front and this will leave us with a mostly dry day on Friday.
