    For the 12Z TAFs...
    Low-end IFR to LIFR ceilings are prevalent across the area at 12Z
    TAF issuance, with some LIFR visibility also present at RFD/DPA.
    Ceilings will likely remain steady through 13Z before daytime
    heating begins to slowly lift them through the morning. Visibility
    should also quickly improve by 14Z. Ceilings will eventually
    become MVFR and/or scatter out by this afternoon. There is
    increasing confidence that IFR ceilings will advect back into
    northeast Illinois and northwest Indiana from Lake Michigan this
    evening, then persist through the night. However, if this does not
    occur, SKC conditions with higher chances of lower visibility from
    BR/FG would become the most likely scenario.
