Occasional light rain showers will come to an end this morning as an upper level disturbance lifts north of the area. A warm front across central Illinois will lift northward today and reach far northern Illinois later this afternoon, although the front is expected to hang up closer to Lake Michigan due to the colder water temperatures. High temperatures will range from the lower to mid 60's far south...to the upper 40's across extreme northeast Illinois. A stronger upper level disturbance will take aim on the area on Thursday, bringing heavier rain and some embedded thunderstorms to the area.
