For the 12Z TAFs...
Concern today will be if the lake breeze will make it to ORD/MDW,
then on timing our next batch of rain late tonight and Sunday.
High will shift to the eastern Great Lakes today. Therefore light
winds and mostly clear skies will begin this operational period.
Winds will likely veer a bit west of south today, and then drift
closer to south through the day. We still feel the lake breeze
will just impact GYY and the lakeshore areas, however this will
bear watching as any minor change in the strength of the low level
winds could result in a flip over to an east wind direction at
ORD and MDW. MDW (and maybe ORD) also stand the chance to shift to
more of a southeast wind late this afternoon/early evening, but
speeds should remain on the lighter side.
Precipitation in the form of rain will hold off until overnight.
Expect that it will continue into Sunday morning, with some breaks
possible at times Sunday. But expect low VFR or even MVFR cigs
once the rain begins.
