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.
