Area Forecast Discussion
National Weather Service Northern Indiana
347 PM EST Fri Jan 20 2017

Issued at 1152 AM EST Fri Jan 20 2017

Overcast skies accompanied with some patchy fog and drizzle will
remain this afternoon and temperatures will be in the mid 40s to
lower 50s. Chance for light rain returns tonight along with areas
of fog by Saturday morning. Unseasonably mild temperatures are
expected over the weekend with highs in the 50s and lows in the


.SHORT TERM...(This Evening through Saturday)
Issued at 346 PM EST Fri Jan 20 2017

Very mild and moist air was spreading northeast into the forecast
area with temperatures rising near 20 degrees above normal. Areas of
fog had somewhat dissipated through early this afternoon, although
visibilities were still around a mile over far southern Lower
Michigan during the middle of this afternoon. Have decided against a
dense fog advisory tonight. Fog should redevelop, but the latest
high res WPC runs and conditional climatology support most
visibilities falling to around 1 mile. However, locally lower
visibilities are likely. Temperatures should be steady or slowly
rise tonight, so roads should be just wet with no ice expected.
Highs Saturday should climb into the 50`s Saturday and may top 60
degrees over southeast areas. Record highs at South Bend and Ft
Wayne are in the low to mid 60s. Skies should remain cloudy or
mostly cloudy with light precipitation possible, but heavy rain is
not expected.


.LONG TERM...(Saturday Night through Friday)
Issued at 346 PM EST Fri Jan 20 2017

Overall, a very mild pattern for the latter half of January
will persist through the middle of next week. Some rain is
possible Monday as the northwest edge of an upper level system and
associated low pressure area track southeast of the area. Have
raised rain chances Monday over mainly northwest Ohio. Otherwise,
mild conditions with continue through Wednesday with highs in the
40s and 50s. Record warm lows around 45 degrees may be set
Sunday. Temperatures will be turning colder Thursday and Friday as
the upper level trof moves east.


.AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon)
Issued at 1152 AM EST Fri Jan 20 2017

IFR and LIFR flight conditions will persist for the next 24
hours. Drizzle and fog is expected to keep visibility and ceilings
low this afternoon. Guidance is suggesting fog to develop
overnight that may further reduce visibility early Sat morning but
confidence in timing and duration is low at this time, hence kept
out of forecast.
