.SHORT TERM (This evening through Monday)...
Issued at 242 PM EST Sun Jan 11 2026

Surface analysis early this afternoon shows low pressure over Quebec
and high pressure over OK. A ridge axis extended north from the
high, stretching to MN and the western Great Lakes. GOES16 showed a
shield of cloud cover within the cyclonic flow stretching across the
Great Lakes and including Indiana. Clear skies were found to the
southwest with the associated high, while northwest flow aloft has
allowed mid and high clouds within that flow to stream across the
upper midwest. The earlier snow showers/flurries have exited.

Tonight...

Northwest upper flow is expected to continue...allowing a steady
stream of mid and high clouds to push across Indiana overnight.
Meanwhile within the lower levels the surface high is expected to
build eastward, allowing the ridge axis to push across Indiana
through the night. Forecast soundings show a dry column within the
lower levels with some saturation aloft, which is indicative of the
passing high clouds. Thus after this pesky stratus deck exits, skies
will be partly cloudy overnight. Warm air advection is in play
tonight on westerly winds aloft. Thus will trend lows to the middle
20s.

Monday...

Another dry, quiet weather day will be in store. Indiana will remain
under NW flow aloft while an upper level disturbance pushed across
Michigan and the Great Lakes. This forcing will stay well north of
central Indiana. Strong surface high pressure will be settling
across the deep south. This will result in a dry and mild southerly
flow in place across Indiana.  Time heights show a dry column
through the day as do the time height sections. Thus will expect a
partly cloudy and warmer day. Warm air advection will continue to be
in play, and this will allow temperatures to recover to the lower to
middle 40s for highs.

.LONG TERM (Monday night through Sunday)...
Issued at 242 PM EST Sun Jan 11 2026

With very brief exception, upper level longwave troughing will be
present across the eastern portion of the country throughout much of
the week and into the coming weekend. This will produce a general
cooling trend through the work week and weekend, as multiple
individual shortwaves and cold fronts drop through the region.

Precipitation chances will arrive as early as Tuesday afternoon with
the first cold front, though temperatures should be warm enough in
the low levels for this to fall as rain Tuesday into Tuesday night.
A secondary cold front accompanied by the main push of Arctic air
follows shortly after on Wednesday, which will allow a gradual
changeover of rain to snow Wednesday afternoon into Wednesday night,
with some potential for light accumulations.

A brief break is expected Thursday, though there is at least some
potential for lake effect flurries to sneak into central Indiana,
before the next systems in the wave train bring additional low snow
chances Thursday night into Saturday night. Guidance inconsistencies
prevent more than low to middling chance PoPs at this point, but
additional light accumulations cannot be ruled out. Yet another
reinforcing shot of Arctic air appears likely, which will bring lows
down into the teens most nights and highs no warmer than the low to
mid 30s, with several days likely to struggle to get out of the 20s.

Wind chill temperatures will be in the single digits at times from
mid week onward, with subzero wind chills not out of the question
depending upon snow and cloud cover.

Discussion:

MVFR ceilings will improve to VFR later this evening into tonight as
high pressure builds. VFR conditions are then expected for the
remainder of the period.

Westerly winds will become southwesterly tonight and diminish
slightly before increasing again Monday morning. Wind gusts between
22-30 kts are possible during the day Monday.
