Area Forecast Discussion
National Weather Service Northern Indiana
648 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)
Issued at 517 AM EDT Wed Oct 19 2016

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.


.LONG TERM...(Friday through Tuesday)
Issued at 517 AM EDT Wed Oct 19 2016

Much cooler weather can be expected Friday through Sunday as an
upper level trof deepens east of the area. Temperatures will be a
little below normal into early next week. Little if any rain is
expected through this period.


.AVIATION...(For the 12Z TAFS through 12Z Thursday Morning)
Issued at 637 AM EDT Wed Oct 19 2016

Low level ridge axis settling into the area this morning has
allowed for patchy fog formation across portions of northern
Indiana. May need to continue to carry tempo IFR vsbys at
terminals through 13Z this morning, but otherwise VFR conditions
are anticipated through the forecast period. Mid clouds should
increase late afternoon and especially by this evening in advance
of next upper level short wave trough. This trough will interact
with baroclinic just south of the area this morning to produce a
likelihood of rain across NE Indiana late this period and
extending into Thursday.


IN...Dense Fog Advisory until 9 AM EDT /8 AM CDT/ this morning for

MI...Dense Fog Advisory until 9 AM EDT this morning for MIZ077>081.

OH...Dense Fog Advisory until 9 AM EDT this morning for OHZ001-002.
