Area Forecast Discussion
National Weather Service Northern Indiana
622 AM EST Mon Jan 19 2026

.KEY MESSAGES...
- Lake effect snow continues today on into Tuesday. The heaviest
  falls this morning and continues to weaken through the period.
  Additional snow amounts total 2 to 4 inches across the
  advisory locations in MI, whereas less than 2 inches
  additional snow is forecast for the Indiana counties in the
  advisory.

- Dangerous wind chills around 15 below zero expected late today
  through early Tuesday.

- Another fast moving system will bring some light snow
  accumulations Tuesday night into early Wednesday, especially
  along and north of the Toll Road. Still, another system
  provides snow and lake effect snow for Wednesday night and
  Thursday.

- Temperatures moderate back into the lower 30s briefly
  Wednesday, but temperatures turn colder once again for latter
  portions of work week into next weekend.

.DISCUSSION...
Issued at 308 AM EST Mon Jan 19 2026

Cold air advection was entering the area this morning behind the
arctic front and this sets up two hazards for Monday.

The first of which is the snow. Lake effect snow is underway across
the area as southwest winds veer more west northwesterly today.
Favorable trajectories, ample theta-e instability, and low level
moisture all make the atmosphere conducive to lake effect snow.
Initial lake induced inversion up between 7500 and 8500 ft fall
slowly during the day today indicating the intensity of lake effect
snow is expected to slowly slacken through the period, which is also
evident by the general tendency to lose low level moisture. Another
negative for this is that while we have good omega cross hairs with
the DGZ, the moisture is actually much higher in the atmosphere
meaning we're getting more plates than dendrites lowering the SLR a
little. Still, given the cold air, the dry snow and gusty winds,
initially gusting 30 to 35 mph that do relax a little to more like
25 to 30 mph by day's end, allow for hazardous driving due to
lowered visibility from blowing snow, but also from drifting snow,
especially on N-S roads. As a strong shortwave crosses Lake MI this
morning it looks to turn those trajectories more westerly and
increase snow rates until around 12 or 13z when the surface trough
pushes eastward away from the lake influence. Light lake effect snow
is expected to continue this afternoon into early Tuesday.

The other hazard is the very cold air. A cold weather advisory
has been issued for wind chills that dip down to -15F. It is a
delayed arrival from what one would normally expect, which is to
get the deepest cold in the early morning and then have
temperatures increase during the day diurnally. This time, we
actually the coldest wind chills mid morning before the winds
slowly relax, but the temperatures stay in the mid to upper
single digits and low teens through the day today. Given the 850
mb stay in the -20s Celsius today and tonight, we have the cold
weather advisory lasting into Tuesday morning. Temperatures are
securely into the mid to potentially lower single digits away
from the lake cloud blanket, but the winds are 10 to 20 mph
weaker Tuesday AM. High pressure passing by to our south Tuesday
morning allows WAA to begin to work into the area so, while
today's highs struggle to get out of the teens, low 20F degree
temperatures begin to poke into our southwest Tuesday afternoon.

Mid level ridging and the WAA's southwest trajectories spell an end
to the lake effect snow Tuesday afternoon. However, a clipper system
is hot on the waning precipitation's heels for Wednesday. A theta-e
plume and Gulf connection is notable in models with this system as
it passes by just to the north of the area meaning it will have to
be interrogated for some snow accumulations as it passes by. It will
also have a lake enhancement response on its back side although it
does appear that the NAM BEH Bufkit soundings indicate much weaker
lake induced instability and dry air in the lowest levels.

Better omega cross hairs with overlaid moisture occurs for a
brief period Wednesday night as another clipper moves through
the area, but there is also indications of riming on the flakes
with the omega center at or just below the DGZ. This system has
a higher dew point plume, but does appear to have a weaker
connection to the Gulf this time around, which would indicate
weaker accumulations than the Wednesday system. The clipper
system is out of the area by Thursday morning and there will be
a lake response on its back side.

It looks like still another clipper system arrives Thursday night,
but that looks much drier and not with much Gulf connection. There's
also a lake response behind it again.

The cold that follows this clipper system for Friday morning is
quite deep with the -25C contour passing through the area and the
negative 30C contour in play. Further evidence to the strong
cold air is the anomalous 1050 mb high pressure system that
passes through the area Saturday/Saturday night.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 622 AM EST Mon Jan 19 2026

Arctic front has just cleared KFWA and expect improving
conditions through the rest of the morning, though blowing snow
may lead to visibilities around 1SM at KSBN through the late
morning. Steady dry air advection will result in slowly climbing
ceiling heights through the day. Winds also relax late in the
day which should limit any vis reduction at KSBN. Some lake
effect snow showers may still clip KSBN tonight but confidence
is too low to include in the TAF at this time.
