Area Forecast Discussion
National Weather Service Northern Indiana
644 AM EST Wed Dec 6 2017

.SYNOPSIS...
Issued at 423 AM EST Wed Dec 6 2017

A few flurries are possible this morning. Otherwise it will be
breezy with high temperatures in the middle to upper 30s by mid
day and slowly falling temperatures late this afternoon. Lake
effect snow showers will bring the first snow accumulations of the
season to the snow belt region tonight into Thursday. Locations
north of the toll road could see total accumulations range from 1
to 4 inches by Thursday evening. It will remain cold through the
weekend with highs around 30 and lows in the upper teens to lower
20s. Snow looks likely again late Friday night into Saturday with
some accumulations possible.

&&

.SHORT TERM...(Today and Tonight)
Issued at 423 AM EST Wed Dec 6 2017

Series of short waves to impact the area this period with lake
effect response developing this evening into Thursday.

Water vapor shows first weak short wave wrapping eastward on
backside of main upper low situated near James Bay. IR shows area of
clouds associated with this feature streaming east but surface obs
in recent hours show little in way of pcpn reaching ground despite
light returns on regional radar mosaic. Given dry lower levels and
weak forcing only expecting some flurries early this morning and
possible sprinkles east mid to late morning as wave departs.
Otherwise skies becoming cloudy early this morning then clearing
away from Lake Michigan late morning into the afternoon hours with
subsidence and further drying behind this wave.

Lake effect snow showers become focus for tonight as secondary cold
front is forced through the region associated with a stronger short
wave. Secondary surge of colder air plunges across the Lake tonight
with delta Ts climbing into the mid 20s with brief window of deeper
synoptic moisture and saturated Dendritic growth zone. Inversion
hovers around 5-6kft and coupled with NW flow should keep snow
showers in more of multi-band formation with brief, heavier squalls.
Activity should begin to pick up in the evening and continue
overnight with intensity peaking near 12z Thu. Still expecting a
general 1 to 2 inches tonight with a localized 3 inch not out of
question. Monitoring part of snow belt for possible advisory given
first accumulating snow of the season but will defer to day shift
with another series of model runs to nail down location if needed.

&&

.LONG TERM...(Thursday through Tuesday)
Issued at 423 AM EST Wed Dec 6 2017

Multi-band lake effect snow showers should be ongoing at start of
period with intensity waning during the afternoon. Another inch or
two with localized 3 inches possible across mainly the Michigan
counties where trajectories look best. Given multi-band nature
doubtful that any location will see the max amounts from both Wed
night and Thursday periods combined so likely a 1 to 3 inch type
event for most with localized 4 inches. Low level flow backs to west
southwest Thursday evening and this should confine any residual
light lake effect to western Cass and northern Berrien counties.

Another stronger short wave on target to drop into western Great
Lakes late Friday night into Saturday. Models still a bit different
on timing but in agreement on light snow likely moving into western
areas late Friday night and eastward Saturday morning. Bumped PoPs
in collaboration with neighbors to likely category. Lake enhancement
expected downwind of Lake Michigan with transition to pure Lake
Effect Saturday with another short but good window for snow showers.
Several additional inches of accumulation possible Saturday
afternoon into Saturday night if deeper moisture hangs around.
Intensity could be stronger during this brief window with deeper
saturated layer and longer fetch with upstream conditioning leading
to some focused bands.

Models and blends picking up on slight warming trend Monday ahead of
next wave. Did not deviate with focus on the early periods and snow
chances but doubtful the blends have taken into account any snow
cover that might get laid down over weekend so temps across the
north likely too warm.

&&

.AVIATION...(For the 12Z TAFS through 12Z Thursday Morning)
Issued at 638 AM EST Wed Dec 6 2017

A very deep surface low was north of Lake Superior early this
morning and was helping to keep brisk winds over Northern Indiana.
Winds should increase to 15-17 knots this morning with gusts to 25
knots. A weak disturbance in strong west flow may bring flurries
to the area today, but for now left snow out until the lake effect
snow showers increase and move inland later tonight. SBN will be
on the fringe of the snow showers given the west fetch over the
lake.

&&

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