The Week ahead: Quiet through thanksgiving. Active weather after?

Thanksgiving week will start out featuring mostly quiet weather for Illinois. A couple weak weather disturbances will move through the state Monday and Tuesday morning. The first will breeze through southern Illinois early Monday, bringing some light mixed precipitation. Another will drop south Monday night and early Tuesday morning bringing a shot at some light snow across mostly northeastern Illinois. Right now any snow accumulation looks to be minor at best - 1" or less. 

Temperatures will quickly moderate in the middle of the week as southerly flow returns. By Thanksgiving we should see temperatures at a comfortable seasonal level. Mid 40s north and 50s south. With the sun coming out if should feel nice - especially when compared to our recent cold snap. 

Medium range models hint at things switching to the more active side Friday and beyond - but with typical track and timing differences. One potential weather maker arrives Friday bringing mostly a light rain threat due to temperatures returning to the mild side. 

Afterwards, a stronger low pressure system may develop bringing a chance for a heavier, wind driven rain. If enough cold air wraps around the back side we could be talking about our next snow maker by the weeks end. That system is still 7+ days out though, so we will see how things continue to evolve. 

Here are the highlights mentioned above as seen on some of the models.

Potential for light snow on Tuesday - not looking like too big a deal right now.

Approximate highs for Thanksgiving - with mixed sun and clouds!

Friday weather maker - right now temperature profiles support mainly a light rain threat. 

Models hinting at a stronger low pressure system to develop around Sunday. We will see if this becomes anything.

So right now there isn't too much to be concerned about - but we do have a couple systems to monitor, especially towards the later part of the week. 

From all of us here at ISC we hope you have a wonderful Thanksgiving and safe travels to all your families!
