Ahead of a cold front approaching from the northwest, a warm southwesterly flow will pull moist unstable air into Illinois today. Saturday saw a couple tornadoes and numerous reports of large hail in North Dakota and Minnesota ahead of the front, and severe storms could redevelop over northeast Illinois this afternoon and early evening. The front is expected to slowly move through and just south of the area overnight with remnant clouds and showers possibly hovering over southern portions tomorrow. Tuesday and Wednesday will see the area under the influence of high pressure. Then a complex low pressure system is forecast to move east out of the northern and central plains. This will result in extensive cloud cover along with showers and thunderstorms here the remainder of the week. Tropical Storm Chris made landfall in eastern Cuba Saturday, and has become just a weak low pressure system.
