Rain, thunder and maybe a few waterspouts

As we head into the weekend it unfortunately looks like our rain chances may increase - especially further east of Rockford.

As that pesky upper level low moves over the Great Lakes tonight and Saturday it will come with a very cold pocket of air above.  Temperatures around 16,000 ft will probably fall to -28°C, which is roughly -18°F!  Any sunshine that occurs will cause the air to quickly rise producing showers.  Because of the rapid vertical motion there could even be a few rumbles of thunder or even small hail.  Another interesting thing that may happen tomorrow is the possibility of waterspouts over Lake Michigan.  The relatively warm water temperatures could help enhance the instability leading to a few waterspouts over the lake.  Either way, should be an interesting day to see what happens!  If you happen to be out that way over the weekend and see anything cool email your photos: weather@wtvo.com.  Who knows, maybe we'll even get a few cold air funnels.
