522 AM EDT Wed Oct 19 2016

Issued at 200 AM EDT Wed Oct 19 2016

Cooler conditions will be in store for the remainder of the
overnight hours behind a cool front. The combination of light
winds and clearing skies behind the front may allow some patchy
fog to form across portions of north central Indiana and southwest
lower Michigan. Highs today will reach into the 70s out in front
of the next widespread rain event Wednesday night into Thursday.


.SHORT TERM...(Today through Thursday night)

The front had moved south to near the Ohio River, but will begin to
move back north later today and tonight as an upper level trof
approaches the area. A wave was developing over the Ozarks early
this morning and will move northeast to near the Ohio River
Thursday. Overall, the ECMWF has been consistent with the
deformation zone and subsequent rainfall associated with this
system. Rain will develop and spread north across most of the
forecast area. The heaviest rainfall should fall from Portland to
Lima where rainfall amounts should exceed 1 inch by early Friday.
