The potential is there for us to see some nasty weather over the next couple of days across northern Illinois and into northwest Indiana.
The National Weather Service has put the region under a Flash Flood Watch through Wednesday morning. The heaviest rain is expected to be near the IL/Wis border, but areas south will have to remain on alert. The ground south of I-80 is already saturated and issues could arise there.
An upper level shortwave is forecast to be moving over the lake as we start the day Wednesday. While the best chance for thunderstorms is expected during the early morning hours we hang onto the chance for scattered thunderstorms during the morning commute.
A cold front is expected to stall just to our northwest and we'll watch for some widely scattered showers and thunderstorms during the day Wednesday. With an upper level push of energy the front should push into the region with a surface low to boot late in the day. That will once again increase our chance for thunderstorms Wednesday evening and into the overnight hours.
Depending on timing wet weather may be with us Thursday morning. Eventually we'll dry out and the afternoon hours should bring some sunshine. A chance for showers and storms then returns Friday afternoon.
