Area Forecast Discussion
National Weather Service Northern Indiana
140 AM EDT Sat Mar 18 2017

.SYNOPSIS...
Issued at 742 PM EDT Fri Mar 17 2017

Areas of fog and some light drizzle is expected through the
evening ahead of a cold front that will move through late tonight.
The front will lead to improved visibilities and a few rain and
snow showers late tonight into Saturday. Highs Saturday afternoon
will top out in the upper 30s to lower 40s. High pressure will
move back into the area Sunday resulting in dry weather with near
normal temperatures. Rain is likely late Sunday night into Monday
as another cold front moves through with colder temperatures
returning for the middle of next week.

.SHORT TERM...(This Evening through Saturday)
Issued at 339 PM EDT Fri Mar 17 2017

While some slick spots will persist a bit longer, have cancelled
the advisory as temps have generally reached or exceeded freezing.
Last of the precip was exiting to the northeast with at least
some clearing potential before cold front and next shortwave bring
at least a chance for some rain/snow showers. Prior to the fronts
arrival, increase in low level moisture will result in expanding
fog into this evening before the front scours out the low level
mstr. Have added mention through 3z with patchy drizzle.

Lake enhancement will start overnight into Saturday morning.
Delta T`s won`t be overly impressive (near 10 C) but combined with
the synoptic features should see at least scattered rain/snow
showers into Saturday morning. Chances should quickly diminish
Saturday afternoon.

&&

.LONG TERM...(Saturday Night through Friday)
Issued at 339 PM EDT Fri Mar 17 2017

Moderating temperatures are expected into the first part of the
next week ahead of the next system to bring a good chance for at
least some shower activity. Sunday night into Monday a cold front
will sweep through with at least 1 round of showers and maybe a
few storms as limited instability arrives. Have left any thunder
mention out for now. Highs Monday will reach into the 50s before
the front passes with temps then back to more normal levels.

Temperatures will fall back below normal for mid week before the
next trough digs into the west and sends heights rising with
potential for 60s by Friday along with increasing shower/storm
chances.

Cdfnt in association with intense clipper dropping through lower MI

rises in wake of fropa with rising temps and veering to wrly winds
leading to rapid scour of both fog and low stratus. Upstream post

mvfr cigs of which will overspread back across the terminals before
