Area Forecast Discussion
National Weather Service Northern Indiana
105 AM EDT Wed Oct 18 2017

.SYNOPSIS...
Issued at 755 PM EDT Tue Oct 17 2017

An upper level ridge will build into the region and bring mild
temperatures to the area over the next several days. Highs in the
65 to 70 degree range will moderate into the lower to middle 70s
by this weekend. Chances for rain increase Saturday night ahead
of a strong cold front that will bring much colder weather to the
area early next week.

&&

.SHORT TERM...(This Evening through Wednesday)
Issued at 344 PM EDT Tue Oct 17 2017

Return flow will continue through Wednesday as the center of a large
high pressure area drifts to the mid-Atlantic Seaboard. After winds
of 5 to 10 mph tonight, winds will increase Wednesday with daytime
heating and mixing to 10 to 20 mph with some gusts above 25 mph by
afternoon. Very limited moisture will be available for clouds, so
clear to mostly clear conditions will prevail.

&&

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 344 PM EDT Tue Oct 17 2017

Several more warm and dry days are ahead as an upper level ridge
builds toward the Ohio River Valley. Temperatures should rise at
least 10 degrees above normal at times through the end of the week.
The pattern should start to break down by late this weekend as a
large upper level trof becomes negatively tilted toward the Upper
Great Lakes region. It looks like the colder air will come in 2
stages, with the secondary and stronger cold front moving across the
area Monday night. Favor the GFS handling of this system that has
been reasonably consistent since Monday morning. After coordinating
with neighboring offices, have lowered Tuesday high temperatures of
the model blend significantly given very chilly air with 850 mb
temps near 0C per GFS and EC and given clouds and showers.

&&

.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1234 AM EDT Wed Oct 18 2017

VFR conditions to prevail through the period and beyond.
Mixing of somewhat stronger wind fields aloft will occur once
inversion is lost with some gusts near 20 kts. Quick loss of gustiness
will occur after 00Z.
