under a half inch for most areas from I-72 northward, with amounts
closer to an inch more common close to I-70 and southward. Winds
will begin to shift to northerly Monday evening northwest of the
Illinois River, and throughout central and southeast IL by Tuesday
evening as a cold front traverses the area. With the decreasing
winds and decreasing mixing heights the next few days, ventilation
rate will decrease and become Poor.
