What forecasters said that day

The local office's own words before this high wind 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 high wind warning went out at Jan 12, 12:39 PM EST, 1 hour 38 minutes earlier.

Area forecast discussion, Jan 12, 12:39 PM EST, 1 hour 38 minutes before
Area Forecast Discussion
National Weather Service Indianapolis IN
1239 PM EST Fri Jan 12 2024

.Key Messages...

- Wind Advisory today and tonight; Wind gusts of 40-45 MPH today, up
to 55mph tonight.

- Rainy and Windy today. 1-2 inches possible.

- Windy and Much Colder tonight, with snow showers possible. Minimal
snow accumulations.

- Very cold Saturday Night-Tuesday Night with sub-zero wind chills

&&

.Forecast Update...
Issued at 936 AM EST Fri Jan 12 2024

The forecast remains on track today with only minor adjustments
made. Current surface observations show a deepening low pressure
system centered near the MO/IL border with a warm front extending
east into central Indiana. The first round of rain this morning
was associated with the warm front lifting north. Latest radar
imagery shows a dry slot across much of central Indiana.

Expect this lull in precipitation to be brief as an intense LLJ
advects deeper moisture northward during the day. Steady moderate
rainfall, possibly heavy at times, will result in widespread
rainfall amounts of 1-2 inches. The threat for widespread flooding
is low, but localized flooding in low-lying areas is possible.
Strong winds are expected today with occasional gusts up to 50
mph. A tightening pressure gradient on the back side of the
aforementioned surface low will lead to more widespread gusts up
to 55 mph by the early evening hours.

&&

.Short Term...(This afternoon through Saturday)
Issued at 936 AM EST Fri Jan 12 2024

Surface analysis early this morning shows deep low pressure over SW
MO. A cold front trailed this area of low pressure into eastern OK
and eastern TX. A warm front was found from the low, across southern
MO and then across KY. Easterly Surface winds were found across
Central Indiana, with dew point temps in the upper 20s to around 30.
Aloft, water vapor showed a deep trough of low pressure over the
Central Plains, resulting in the previously mentioned associated
surface low. Showers and storms within the warm sector were found
over Arkansas, while lighter showers were found ahead of the warm
front over Central IL. GOES16 shows abundant cloud cover ahead of
the convection to the southwest streaming toward Indiana.

Today...

An active weather day will be in store. The strong surface slow is
suggested to push northeast toward Indiana today, allowing the warm
front to the south to push across Central Indiana. Models suggest a
very strong LLJ ahead of the surface low with winds near 50 knots
amid this flow across Central Indiana. A strong pressure gradient is
also expected today as this possibly historically deep low pressure
system pushes across Central Indiana this afternoon. Thus strong
gusty winds around 40 mph with isolated higher gusts will be
possible this afternoon and tonight. Caveat remains this afternoon
as lower clouds arrive if we will be able to mix down some of those
higher gusts. For now the Advisory level wind gusts appear to be
quite certain, thus will trend toward Wind advisory today. Should it
become apparent that an organized area of higher winds, clearing
developing (unlikely), or some rogue convection develop (Better
chances for that south of Central Indiana), short-lived high wind
warnings will be used.

Strong isentropic lift is in place today. The GFS 290K surface shows
strong upglide with specific humidities up to 4.5 g/kg. Best lift is
present during the morning and early afternoon hours as the low to
the southwest approaches. HRRR shows two main pushes of rain today.
The first arriving near rush hour and the second late this morning
and afternoon as the warm front pushes north across the forecast
area. Forecast soundings today show a deeply saturated column with
pwats near 0.70 inches. Thus confidence for rain today is high.

Today's expected impacts include: Rainy and windy conditions, with
brief heavy rain possible. Wind gusts to around 40-45 mph will
result in unsecured outdoor items being blown about. Isolated tree
limbs being blown down and associated isolated power outages will be
possible.

Tonight...

As we start tonight, the strong surface low will continue to be
deepening and found over northern Indiana. Models suggest this low
will then push northeast to Lake Huron, deepening all the way. This
will continue to keep a strong surface pressure gradient in place
across Central Indiana amid cold air advection and cyclonic lower
level flow. The cold front associated with the low will push east of
Central Indiana by 00Z, resulting in very windy and cold conditions.
Also as the low departs the 290K Isentropic surface shows strong
downglide and drying. Forecast soundings show dry air arriving
aloft, but saturated lower levels due to trapped lower level
moisture. Given the cyclonic flow, a few scattered light snow
showers will be possible, but confidence is low in this. HRRR shows
very little organized development. Thus will keep some mention of
snow showers through the evening hours as the low departs.

Strongest winds of the day should be during the evening hours. The
pressure gradient across the area at that time will be strongest as
the low deepens and subsidence ongoing may help some of the higher
winds aloft mix downward. The 850mb winds will remain around 40-50
knts through the evening. Thus gusts in that range do not seem out
of the question. Again will keep the advisory focused from mid
morning through early Saturday morning.

Tonight's expected Impacts include: Windy conditions, with gusts to
around 45-50  mph. This will result in unsecured outdoor items being
blown about. Isolated tree limbs being blown down and associated
isolated power outages will be possible. Snow showers are possible,
with blowing snow reducing visibility.

&&

.Long Term...(Saturday through Thursday)
Issued at 301 AM EST Fri Jan 12 2024

Saturday and Saturday night...

Initially, central Indiana will still be close enough for some
influence from the surface low over northern portions of the region
Saturday morning. Trends have been pushing in much drier 700-500mb
air in behind the low, leading to a quicker end in surface low
related snow showers.

The upper level low will still linger behind however, creating
isolated snow showers and snow flurries once again during the day on
Saturday. With mid to low level temperatures plummeting beneath
strong CAA, minimal moisture will be needed to squeeze out a tenth
or two of snow accumulations. Snow rates dont look to be too high
though with lapse rates failing to promote upscale growth within
shower activity.

As mentioned, mid to low level temperatures will drop steadily
throughout Saturday, but surface temperatures will lag slightly
until the upper low departs Saturday night. Once the upper low
departs, uniform NW flow and diurnal cooling will push surface
temperatures from the low 20s Saturday evening, down to the single
digits by Sunday morning. Continued modest wind will make
temperatures feel even colder with wind chill values below -10

Sunday through Tuesday...

This will be a period of very cold temperatures as Arctic high
pressure remains in control at the surface.

Even with surface high pressure, an upper level disturbance will
push through Sunday night. Now, when I say "upper-level", this only
means 15000 feet above the surface since the tropopause will be down
near 500mb over this stretch. Because of the condensed troposphere,
dry surface layers wont be able to deter snowfall much within upper
level disturbance. With this in mind, there will be increasing
chances for snow, mainly over southern portions of central Indiana
Sunday night into Monday morning. The bulk of the forcing looks to
remain south of central Indiana, limiting chances to between 15-40%
for our area. If snow does fall, snow rates will be very high (15-
20:1), allowing for efficient accumulations even with low QPF.

Another upper disturbance could bring more light snow around Monday
night into Tuesday morning. Models begin to vary significantly this
far out though, with questions still remaining about moisture
availability and where the upper level trough will track

Highs will be in the single digits above zero to the teens, with
lows from around zero into the positive single digits. Temperatures
will be influenced by cloud cover timing and any snow that does
fall, so these numbers may change. Wind chills will be below zero,
with readings down to around -15 at times for portions of the area.

Wednesday and beyond...

The Arctic high begins to move out mid week, with slight moderation
possible as surface winds veer towards southerly. This could allow
for highs back into the 20s and even 30s by Thursday. This will be
short lived however, with another through passing through late next
week, and continued arctic air behind the trough.

.Aviation...(18Z TAF Issuance)
Issued at 1239 PM EST Fri Jan 12 2024

Impacts:

- IFR Conditions expected through this evening, possibly improving
to MVFR tonight

- Strong low-level wind shear possible through the day

- Gusty winds this afternoon with peak gusts at around 40kts; Wind
gusts near 45-50 knots possible this evening and tonight.

Discussion:

A deepening area of low pressure just west of central Indian will
support widespread moderate rainfall this afternoon along with IFR
conditions. A strong 850mb LLJ associated with the low will also
promote windy conditions through the TAF period, especially this
evening into tonight with the potential for wind gusts around 45-50
kts. There is the potential for LLWS mainly through the early
evening hours, mainly for speed.

Tonight the low will depart northeast and a cold front will push
across the TAF sites. Wrap around snow showers will be possible with
gusty winds. Thus have included a blowing snow mention tonight. IFR
conditions should improve to MVFR late overnight.
