Area Forecast Discussion
National Weather Service Northern Indiana
213 PM EDT Sat Jun 24 2017

.SYNOPSIS...
Issued at 207 PM EDT Sat Jun 24 2017

Mainly dry and cooler conditions are in store for the remainder of
the weekend into early next week. An isolated shower will be
possible late this afternoon through Monday, but expect most
locations to remain dry. Lows tonight and Sunday night will fall
into the 50s, with highs on Sunday and Monday in the upper 60s to
low 70s. Fair weather and gradual warming can then be expected
into Tuesday and Wednesday before a more active weather pattern
returns Thursday into Friday.

.SHORT TERM...(Late This Afternoon through Monday)
Issued at 207 PM EDT Sat Jun 24 2017

Mainly dry and unseasonably cool weather will persist through Monday
as a large/broad upper level trough settles into the Great Lakes
region. There will be a few low chances for isolated rain showers
through the period. Steepening low level lapse rates augmented by
weak forcing (from a mid level impulse leading a much more
pronounced circulation over MN) may force a few isolated showers
this afternoon, mainly over ne IN/sc Lower MI/far nw OH where some
weak instability may be realized.

The aforementioned upper low over MN will translate ese through the
lower Great lakes later tonight, with a few showers possibly
surviving into northern portions of the forecast area later this
evening/overnight on leading edge of height falls/weak trough. Most
locations will likely remain dry this afternoon into tonight.

Sunday will be another mainly quiet and slightly cooler day as
another surge of cold advection rushes in behind tonight`s
secondary trough. Shower chances once again look very low with the
local area likely in between shortwaves. More of the same then
into Sunday night and Monday, though will continue with low
chances for isolated showers/sprinkles (mainly north) as
additional shortwaves pivot through in cool/cyclonic flow.

&&

.LONG TERM...(Monday Night through Saturday)
Issued at 207 PM EDT Sat Jun 24 2017

Temperatures will moderate back closer to seasonal norms into the
middle of the week as heights build aloft. A more unsettled/active
pattern then returns Thursday through Saturday as a series of
pacific waves interact with a low level frontal zone/theta-e
ridge laying out from IA east into the Lower/Central Great Lakes.
