--STORM TEAM FORECAST--
A east-west cold front lying just to our north from around Des Moines to the Wisconsin-Illinois border will slip to the south during the day on Tuesday. This will bring in cooler conditions across the northern part of the state by the afternoon on Tuesday. A low pressure center in the western Plains will track eastward and then south-eastward before moving along the frontal boundary which by late Tuesday will be across mid Illinois.
This will bring in moisture from the south over the front where it will cool and fall in the form of snow. Meanwhile precipitation in the warmer air will fall in the form of rain with a transition being a frozen mix of sleet, snow and rain.
The greatest snowfall potential unfortunately lies right across mid Illinois and northern Indiana and to the north. As the front moves to the east rain will change over to snow over much of the abc/NewsChannel 15 viewing area. A snowfall total of between 2 and 5-inches will be possible by early Wednesday morning.
On the back side of the front we expect much cooler conditions on Wednesday and Thursday before the temperatures make a jump back into the mid 50s by Friday. Another storm system will be possible by the second half of the weekend, even though, right now, any precipitation appears to be rain.
Be sure and follow any precipitation on INTERACTIVE RADAR!
--6-10 DAY OUTLOOK--
March 16-20: Both temperatures and precipitation look to be below average during this time period.
