Area Forecast Discussion
National Weather Service Northern Indiana
319 PM EDT Sun Oct 22 2017

.SYNOPSIS...
Issued at 313 PM EDT Sun Oct 22 2017

Chances for rain will increase west of Interstate 69 tonight as a
front moves east. Rain will likely engulf the entire forecast
area Monday into Monday evening as low pressure develops into the
Great Lakes region. Rainfall amounts between 1 and 3 inches will
be possible in northeast Indiana, northwest Ohio, and south-
central Lower Michigan. Much cooler and showery weather is
expected behind this system into Tuesday and Wednesday, with highs
on Wednesday likely struggling to get out of the 40s.

&&

.SHORT TERM...(This Evening through Monday Night)
Issued at 313 PM EDT Sun Oct 22 2017

Relatively weak showers were developing ahead of the front near the
IL/IN border in an area of low level theta e convergence. On Sunday
afternoon, the front was near Lincoln IL and extended northeast
toward Chicago. The upper low will move northeast across the Ohio
River Monday as the trof becomes negatively tilted and as the front
moves east. This will cause rapid cyclogenesis and a significant
deformation zone to form on the northwest section of the surface
low. Continue to favor the ECMWF which has gained support from the
NAM with the 12Z run. Heavy rain is likely over northern Indiana
into far northwest Ohio and far southern Lower Michigan. Have
coordinated with the Ohio RFC and neighboring offices in this regard
for heavy rain the possibility of an areal flood watch, but
following much discussion and reflection, decided to hold off with
the watch given very dry conditions at the onset. Also, although
rainfall amounts of 1.25 to 2.5 inches are expected, runoff
should be more gradual helping to reduce the chance for
widespread flooding concerns. Will continue to mention localized
flooding in the Hazardous Weather Outlook.

&&

.LONG TERM...(Tuesday through Sunday)
Issued at 313 PM EDT Sun Oct 22 2017

Much colder air will spread across the Upper Great Lakes region
Tuesday accompanied by lake enhanced showers with delta T values
rising to or exceeding 15C. Highs Tuesday should only be between 50
and 55, and then cooling to around 48 Wednesday as 850 mb
temperatures fall below 0C. Lowered highs Tuesday to around 50 over
most areas as 850 mb temps fall below 0C. There should be a short
break in the rain Wednesday night through Thursday night before the
next system arrives. Colder air is expected to arrive this weekend
with lows dropping close to freezing Sunday morning.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 0200 PM EDT Sun Oct 22 2017

Clouds will continue to fill in this afternoon and evening with
rain to follow. VFR conditions will hold for a few more hours at
KSBN, while KFWA is likely VFR through part of the night. Ceilings
will need to be monitored closely after 6Z as guidance attempts
to drop ceilings lower than currently forecast. At this distance,
we opted for a more optimistic solution but will pass the note
along to the later shifts.

.IWX WATCHES/WARNINGS/ADVISORIES...
IN...NONE.

OH...NONE.
