...WINTER STORM WARNING IN EFFECT FROM 10 AM SUNDAY TO 1 PM EST 
MONDAY...

* WHAT...Heavy snow expected. Total snow accumulations between 4 and 
  8 inches. Isolated higher amounts possible south of I-70. Winds 
  gusting as high as 35 mph.

* WHERE...Portions of central, east central, and west central 
  Indiana.

* WHEN...From 10 AM Sunday to 1 PM EST Monday.

* IMPACTS...The strong winds and weight of snow on tree limbs may 
  down power lines and could cause sporadic power outages. Travel 
  could be very difficult. The hazardous conditions could impact the 
  Monday morning and evening commutes.

* ADDITIONAL DETAILS...There may be a sharp south to north snowfall 
  accumulation gradient across Central Indiana. Lower confidence 
  exists in exactly where this sharp gradient sets up, but latest 
  guidance suggests it could be near or just north of the Indy metro 
  area. Snow amounts could vary greatly over short distances. Stay 
  tuned for further updates on the forecast.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you must travel, keep an extra flashlight, food, and water in 
your vehicle in case of an emergency. The latest road conditions for 
the state you are calling from can be obtained by calling 5 1 1.

Persons should delay all travel if possible. If travel is absolutely 
necessary, drive with extreme caution and be prepared for sudden 
changes in visibility. Leave plenty of room between you and the 
motorist ahead of you, and allow extra time to reach your 
destination. Avoid sudden braking or acceleration, and be especially 
cautious on hills or when making turns. Make sure your car is 
winterized and in good working order.

What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Indianapolis, IN wrote its last area forecast discussion before this winter storm warning went out at Jan 4, 12:39 AM EST, 1 hour 51 minutes earlier. Its key messages:

  • Below normal temperatures expected for the foreseeable future. Bitterly cold conditions likely by mid week next week.
  • WINTER STORM WATCH for a significant winter storm expected to impact the region Sunday - Monday. Slight shift southward in greatest snowfall amounts.

National Weather Service Indianapolis IN
1239 AM EST Sat Jan 4 2025

.KEY MESSAGES...

- Below normal temperatures expected for the foreseeable future.
  Bitterly cold conditions likely by mid week next week.

- WINTER STORM WATCH for a significant winter storm expected to
  impact the region Sunday - Monday. Slight shift southward in
  greatest snowfall amounts.

&&

.SHORT TERM (This evening through Saturday)...
Issued at 302 PM EST Fri Jan 3 2025

Tonight.

Surface high pressure over the Midwest will provide quiet weather
conditions. The pressure gradients decreasing as high pressure
builds will also lead to lighter winds as through the night with any
gusts wrapping up by this evening. Cloud cover will continue to
gradually decrease through the night as dry air continues to advect
into the area. The combination of clearing skies and winds dropping
closer to calm will allow for efficient radiational cooling with
lows falling into the teens. A gentle NW breeze on top of the cold
temperatures could result in single digit sub-zero wind chills for
northern counties.

Saturday.

Expect the colder temperatures to persist through Saturday keeping
temperatures below normal as highs struggle to climb above the low
to mid 20s. Cloud cover will gradually begin to increase late in the
day ahead of the winter storm, but otherwise quiet conditions are
expected.

&&

.LONG TERM (Saturday night through Friday)...
Issued at 302 PM EST Fri Jan 3 2025

OVERVIEW -

The primary concerns for the long term forecast are twofold.

1) WINTER STORM WATCH for a winter storm expected Sunday into
Monday, with potential for significant to major impacts, in the form
of heavy snow, sleet/ice accumulations, and gusty winds/blowing and
drifting.

2) Bitterly cold conditions arriving in the wake of this storm,
likely persisting well into the week 2 period before improvement.

WINTER STORM SUNDAY INTO MONDAY -

As has been discussed previously, the Ohio Valley has an impending
winter storm of which will approach central Indiana Sunday morning,
with impacts through most of Monday. This particular set-up is not
typical for a large impactful winter system, and thus is creating
many challenges in regards to the forecast.

Most of the abnormalities lie in the presence of a broad deep trough
over the eastern portions of Canada and New England. This trough is
working two fold, both limiting northeastward progression of the
impending low, and keeping antecedent conditions well below
freezing. Regardless, a trough will push eastward this weekend with
a resulting low developing generally over the Ozarks/Mid-Mississippi
Valley.

Due to this Canadian trough, typical phasing of the low will be
shunted, keeping progression mostly E to ESE. There is still some
discrepancy on low track with ensemble members varying from central
KY to central TN as of the 12Z suite. The central TN solutions have
become slightly more abundant in the latest runs, leading to a
southward trend in QPF and resulting impacts. Timing has been a bit
more consistent in the latest suite of model guidance with
precipitation onset occurring sometime on Sunday morning into the
early afternoon for central Indiana.

Precipitation type issues is likely to occur Sunday morning through
the afternoon as a 50-70kt 700-850mb jet will push much warmer air
into central Indiana above a well below freezing near surface. The
current though is for much greater coverage of sleet vs freezing
rain for central Indiana due to the entire 0-3km layer remaining
below freezing. With that said, there is some uncertainty due to
potential for the warm nose to be warmer than 3C for portions of
southern central Indiana. If this does occur, rain will likely have
a hard time re-freezing before reaching the surface resulting in
more widespread FZRA. Along and north of I-70, the warm nose should
remain below freezing with any precipitation falling rimed,
dense snow through Sunday afternoon.

Dynamic cooling as the CCB strengthens will likely push mixed
precipitation further into southern IN and KY Sunday evening through
Sunday night. It is at this time that greatest snowfall rates are
most likely for central Indiana with 700-500mb vertical lift
increasing and co-located inside the DGZ. There is also some
potential for deformation banding to begin late Sunday night into
Monday morning, but will greatly depend on if the the WCB is able to
overcome the Canadian trough and develop a TROWAL. This is being
analyzed in the GFS and NAM deterministic solutions. Given the high
SLRs with this portion of the storm, a wide range in 6hour snowfall
amounts is possible between 06Z and 12Z.

Snow will begin to taper off as the system departs to the east, dry
advection aloft begins, and forcing quickly weakens during the day
on Monday, but light accumulations may continue through Monday
afternoon.

*******************************************************************

Summary of Winter Storm:

Given the strong forcing, plentiful moisture, and long duration of
the event due to the orientation and motion of the primary
precipitation band with the system, probabilities are still high for
warning criteria of 5 inches, especially for areas along and south
of I70. Given the slight southward shift, there is now much more
uncertainty for reaching 5+ inches north of I-70, but these areas
will remain in a Watch for now with some potential for these trends
to reverse. Greatest snowfall amounts are likely to remain south of
the I-70 corridor; current forecast is for snowfall totals as high
as 11 inches. Areas that see any mixing of sleet or freezing rain
will likely see much less snowfall totals on Sunday, however impacts
could still be just as bad due to ice accretion. Winds will also be
a concern, particularly Sunday night into Monday, with blowing and
drifting likely becoming at least a moderate concern in that time
frame, with frequent gusts in the 30-35 MPH range and locally higher
gusts. A Winter Storm Watch remains posted for all of Central
Indiana from Sunday morning through Monday evening, no changes have
been made to the timing of the watch with this forecast issuance.

********************************************************************

BITTER COLD -

Guidance strongly suggests the arrival and fairly lengthy
persistence of a potent Arctic airmass in the wake of the winter
storm. Well below normal temperatures are expected from Tuesday -
Wednesday and into the week 2 period, Depending on where the
snowpack forms, there is strong potential for subzero low
temperatures. Kept both highs and lows below guidance for the rest
of the week, nudging temperatures toward the NBM10-25th percentile
given the fact that there will be a healthy snowpack.

MISCELLANEOUS -

Toward the middle of next week and beyond, guidance not only
strongly suggests the aforementioned persistence of a potent Arctic
airmass, but also the passage of one or more upper level shortwave
troughs within the much larger longwave trough/upper low over the
eastern Canadian provinces and the northeastern CONUS. While
moisture is very often difficult to come by for these waves,
cyclonic flow in Arctic airmasses is notorious for producing
persistent flurries or light snow showers, and depending upon the
orientation of the flow, may allow somewhat more substantial lake
enhanced activity to make it down into portions of central Indiana
at times. While these more minor snows are far less predictable,
particularly several days or more in advance, we are likely to see
at least a few periods of light snow across some portions of central
Indiana at times toward the end of the forecast period and beyond,
despite the official forecast remaining dry for now.
