Saturday/Sunday storm update

It's not typical that we get thunderstorms in November, so when they do occur it's something to pay attention to.  A very strong low pressure system developing in the west will move across the Plains Saturday before moving into the Upper Great Lakes Sunday.

A warm front will lift north through Illinois during the day Saturday pulling in a warm and moist air mass.  Dew points Saturday morning will start off in the upper 30s/low 40s but rise close to 60° by Saturday night!  As the warm front lifts through Illinois, a few elevated storms will be possible late Saturday and into Saturday evening.  These storms would be mainly hail producers but could also have a few gusty winds.  The Storm Prediction Center has our far western counties - Jo Daviess, Carroll and Whiteside - under a slight risk for stronger storms. 

Nearly 150 mph jet stream winds will move through Iowa and Missouri late Saturday night into Sunday which could keep the storm threat overnight Saturday.  By Sunday morning, the cold front will be just west of the Mississippi River with much cooler air found behind.  Thunderstorms will remain possible Sunday as the front moves through.  As of Friday afternoon, the greatest storm threat appears to be east of the Stateline closer towards Chicago, but this may shift a little further west either later today or Saturday.  As we continue to monitor the weather for the weekend, be sure to bookmark our page to help you keep tabs on the forecast.
