.DISCUSSION...
Issued at 1048 AM CST Sat Nov 22 2025

A cold front currently approaching from the west moves through the
forecast area mainly this afternoon into the evening hours with 
isolated convection accompanying the frontal passage. Dry 
conditions are then expected for Sunday into Monday along with a 
welcome respite from the nocturnal fog events of late. An upper 
low near the Baja area evolves into an upper trof while 
progressing into the southern/central Plains through Monday. This 
system ejects off across the northeast states Monday night into 
Tuesday while a Canadian system leads to a large upper trof 
evolving over the central states. The upper trof amplifies while 
progressing into the eastern states through Wednesday night, with 
an associated surface low meanwhile bringing a strong cold front 
through the forecast area late Tuesday night into early Wednesday 
morning, with some uncertainty regarding the timing. The system 
which ejects off across the northeast states will bring a region 
of weakening deep layer lift into the forecast area on Tuesday, 
with the 850 mb jet increasing to around 30 knots. MLCAPE values 
of 500-1000 J/kg look feasible along and west of I-65 on Tuesday. 
The 850 mb jet looks to weaken Tuesday night as the front moves 
through, but MLCAPE values of 500-1000 J/kg may be realized 
despite the nocturnal timing. For now, will mention that some 
strong or possibly storms will be possible in the Key Messages for
Tuesday afternoon along and west of I-65 and continue to monitor.
As the front approaches and moves through, will have high rain 
chances shifting across the area Tuesday into Tuesday night, then 
slight chance to chance pops for Wednesday, then dry conditions 
are expected for the remainder of the period.

In the wake of the cold front, lows tonight range from the lower
50s well inland to the lower 60s at the immediate coast. Lows 
Sunday night range from the mid/upper 40s well inland to the 
mid/upper 50s at the immediate coast. Lows Monday night will be 
milder and range from the upper 50s well inland to the mid/upper 
60s at the coast. Lows Tuesday night range from the mid/upper 50s 
well inland to the lower/mid 60s at the coast. In the wake of the 
second cold front, lows Wednesday night range from the mid/upper 
30s well inland to the mid 40s at the coast, then Thanksgiving 
Night will be cooler and range from the lower/mid 30s inland to 
the lower 40s at the coast. Lows Friday night will be similar. 
Highs on Sunday will be mostly in the mid to upper 70s, then 
Monday will range from the mid 70s to around 80 with similar 
values for Tuesday. Wednesday's highs will range from the upper 
60s to lower 70s along and west of I-65 with mid 70s further to 
the east. Thanksgiving Day will be cool and range from the upper 
50s well inland to the lower/mid 60s closer to the coast. 
Temperatures then moderate a bit through Saturday to range from 
the lower 60s well inland to the mid 60s closer to the coast. A 
moderate risk of rip currents is in effect today, then a low risk 
follows for Sunday and Monday. A Moderate risk of rip currents is 
expected for Tuesday and Wednesday. /29

MVFR ceilings this afternoon will lift VFR levels this evening.
Westerly winds 5-10 knots this afternoon shifts northerly Sunday 
morning as a front moves through the area. An isolated shower will
be possible with the frontal passage before midnight. /22

.MARINE...
Issued at 1048 AM CST Sat Nov 22 2025

Light to occasionally moderate southwest to west winds become
northwesterly tonight as a cold front moves through. A 
southeasterly flow develops on Monday and becomes southerly on 
Tuesday. Winds shift to the northwest on Wednesday as a cold front
moves through with a moderate to strong offshore flow for 
Wednesday night. A Small Craft Advisory will likely become 
necessary for most of the marine area Wednesday night into 
Thursday morning. /29

.FORECAST UPDATE...
Issued at 1106 AM EST Wed Nov 26 2025

Winds are increasing across the area with many locations now 
reporting gusts between 30-40 mph. A few reports have already 
reached as high as 45 mph. Expect continued and more frequent gusts 
over 40 mph as we head into the afternoon.

Radar is beginning to show some light echoes approaching from the 
northwest. ACARS soundings out of IND show low-level lapse rates 
(below 850mb) steepening with time. With broad cyclonic flow in 
place, we expect precipitation to expand in coverage. Surface 
temperatures are in the mid to upper 30s as of 11am. Despite this, 
snow will be the primary precip type today. The reasons include the 
aforementioned steep lapse rates. It's quite cold just above the 
surface so any snow flakes will not need to fall through a 
significantly deep warm surface layer. Additionally, soundings and 
observations show the surface layer to be rather dry as well. This 
will help reduce the effects of melting through evaporational 
cooling.

Accumulations are not expected today. Any snow will come in the form 
of flurries or light snow showers. The best chance of such activity 
is with northward extent. We'll include the mention of flurries/snow 
showers in the forecast from about Bloomington northward.

&&

.SHORT TERM (Today and tonight)...
Issued at 301 AM EST Wed Nov 26 2025

*WIND ADVISORY IN EFFECT 7AM-7PM TODAY FOR GUSTS TO 40-50 MPH* 

Today...

Potent early winter wave crossing the Upper Midwest/Great Lakes 
today will maintain 992 mb surface low pressure over northern 
Michigan.  This system's cold frontal zone will continue to cross 
central Indiana through pre-dawn into morning hours...while 1030 mb 
polar high pressure aligned down the Plains slowly builds east.
Gradient between these features will peak over the Midwest during 
the day today, with westerly flow within 15-21Z sustained up to 20-
30 MPH, with gusts up to 40-50 MPH for all but far south-central to 
southeastern zones where gusts to 35-40 MPH will be most likely.

Predominate westerly headings will direct majority of Lake Michigan 
fetch to Michigan/far northern Indiana...although stronger forcing 
embedded in belly of parent trough crossing Indiana through midday 
will encourage widely scattered SHSN over the state's northern 
third, and flurries down to the I-74 corridor.  Can't rule out brief 
visibility reductions for our northern and especially far northern 
counties....with overall flurry activity dissipating by early 
evening.

Temperatures will have fallen to the mid to upper 30s by 700 AM... 
with readings nearly steady through daytime hours.  While far 
southern zones may still be around 40F through early afternoon... 
bigger story will be resultant wind chills in the low to mid-20s for 
most areas under mainly overcast stratus.

Tonight...

Central Indiana to remain in gradient between storm slowly departing 
into southeastern Canada and amplified ridge's axis remaining near 
the Ozarks, however slightly retreat of northern system's dumb-
belling forcing to Great Lakes should create a brief quasi-split mid-
level flow over local region which will help partially-diminish 
winds to more typical robust gusts of 15-30 MPH after midnight.

Stratus should scatter out and lift to mid-levels amid lack of 
forcing, and perhaps surrender to cirrus over several southwest 
counties through the overnight.  The region's coldest night since 
perhaps Veterans Day will be on tap as readings fall through the 30s 
during the evening and into the low to mid-20s by sunrise 
Thursday...with wind chills falling as low as 8 to 20 degrees. The 
normal max/min at Indianapolis through the short term is 47/31.

&&

.LONG TERM (Thursday through Tuesday)...
Issued at 300 AM EST Wed Nov 26 2025

The first piece of the significant pattern change towards colder and 
more unsettled conditions has arrived and will continue to step down 
into early December. The initial impact will be noticeably colder 
air into the first part of the weekend including Thanksgiving but as 
broad meridional upper level troughing takes hold over much of the 
eastern half of the country this weekend into next week...a series 
of storm systems will impact the Ohio Valley with increasing 
potential in multiple opportunities for wintry precipitation 
including snow.

Thursday through Friday

Strong low pressure will continue to pull away from the region into 
eastern Canada on Thursday...but remain close enough to maintain a 
tighter pressure gradient at the surface. Winds remain brisk for 
Thanksgiving Day but peak gusts will be lower than what is expected 
today. Despite increasing sunshine on Thursday it will be cold with 
highs in the 30s. Temperatures may struggle to rise above freezing 
over northern counties and the continued brisk winds will keep wind 
chills in the 20s. Friday will be cold in the lower and mid 30s but 
otherwise should be the best day of the extended holiday weekend for 
any outdoor activities with sunny skies and much lighter winds.

Friday Night through Sunday 

A much more active regime will develop for the weekend as a broad 
upper level trough settling across the eastern part of the country. 
A potent short wave will dive out of the Pacific Northwest on Friday 
then pivot quickly into the region by Saturday evening. Moisture 
will increase in advance of a surface wave poised to eject out of 
the Rockies Friday night then kick E/NE into the Great Lakes by 
Sunday morning.

Precipitation will arrive across the region as early as late Friday 
night and persist into Saturday. Extended model guidance continues 
to struggle on the details with a broad range of scenarios in play. 
That being said...the overall model suite is trending towards snow 
as the primary precipitation type on the front end of the system 
Saturday. Greater uncertainty in precip type develops as the day 
progresses that will largely depend on the orientation...speed and 
intensity of the wave aloft and how quickly warm air advects north 
as the surface low pivots into the mid Mississippi Valley. Trends 
support rain mixing with snow from the south beginning Saturday 
afternoon with an eventual transition to rain over most of the 
forecast area by early Sunday morning as low pressure likely tracks 
to the northwest of central Indiana and temperatures rise through 
the night. Rain will gradually diminish on Sunday in the wake of a 
cold front. Lingering scattered light rain or snow showers are 
possible by Sunday night.

The primary takeaway message for late Friday night and Saturday is 
that there will be a period with light accumulating snow and at 
least some impacts to travel prior to a transition to predominantly 
rain Saturday night into early Sunday before ending. Lower snow to 
liquid ratios are expected leading to a wet and slushy snowfall. 
Specific snowfall amounts remain uncertain at this point but trends 
support 1 to 2 inches north of I-70 with less than an inch further 
south. Stay tuned for updates.

Highs remain in the 30s then rise to a range from the mid 30s to 
lower 40s the first half of Sunday before falling as the day 
progresses.

Sunday Night through Tuesday

After a brief break in the unsettled weather...precipitation will 
return for early next week as an inverted surface trough lifts into 
the Ohio Valley and some phasing of upper level jet energy develops. 
Even less confidence exists with this system but potential for a 
wintry mix or snow is increasing as the coldest air of the season 
advects into the region. Highs remain largely below freezing Monday 
and Tuesday and across the northern half of the forecast area for 
Wednesday. Lows will be in the teens. High confidence remains in a 
cold and largely unsettled pattern continuing for the region through 
the first half of December with additional opportunities for snow 
and wintry weather.

.AVIATION (18Z TAF Issuance)...
Issued at 1222 PM EST Wed Nov 26 2025

Impacts:

- Strong westerly winds through today, gustiness continuing tonight 
  into Thursday

- A few periods of brief, light flurries at times

Discussion: 

VFR conditions are expected throughout the period, though a brief 
drop to the MVFR borderline cannot be entirely ruled out, primarily 
at LAF.

The primary concern for this period will be winds, with sustained 
winds of 20-28KT and gusts to around 40KT through this afternoon at 
all sites, generally from 260-270 degrees. Winds will die down a bit 
this evening, particularly gust speeds, but remain gusty throughout 
the night and into Thursday. Direction will veer slightly later in 
the period to 280-290, with gusts dropping back into the low to mid 
20s range tonight with sustained winds in the mid teens.

A few flurries are occurring, though at any one site these will be 
transient and should cause no restrictions.

No obstructions to visibility are anticipated through the period.

.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 358 AM EST Thu Nov 27 2025

Trough axis will swing across the Ohio Valley this morning as sfc 
high pressure to our west slowly builds in over the Ohio Valley 
today into Friday. Upper trough will also slowly work eastward keep 
us under northwest flow aloft today with slight ridging developing 
on Friday. This will continue to advect in cold air from the north 
and keeping temperatures 15-20 degrees below normal for this time of 
year. With highs in the upper 30s/low 40s today and only the mid 30s 
to low 40s on Friday. Lows Friday morning into Saturday morning will 
also range between 10-15 degrees below normal in the low 20s with a 
few locations dropping down into the teens across the Bluegrass. 

Sfc pressure gradient will remain tight over the Ohio Valley for 
today. Gusty, blustery westerly winds will be around in the 
afternoon, gusts will be between 20-25 mph making it feel like it is 
around 30 in the upper 20s. We will remain dry with mainly clear 
skies into Friday evening.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Issued at 358 AM EST Thu Nov 27 2025

A another system will take shape over the central Plains on Saturday 
then work to the east-northeast through northern IN towards Lake 
Erie by Sunday evening. Warmer air will advect in from the south 
ahead of the approaching system pushing our temperatures into the 
low/mid 40 Saturday afternoon and increasing clouds due to 
isentropic lifting. Precipitation will spread from the west-
northwest to the east during the day Saturday. Initially, 
precipitation could fall as a wintry mix of rain/snow due to 
lingering cold air at the surface early on Saturday. Still some 
discrepancy in the forecast models when it comes to any accumulating 
snow. Current thinking is with a warm ground and temperatures 
warming to above freezing as the precipitation arrives, most will 
see rain with any slushy accumulations of a coating to near an inch 
will be over southern IN, with higher amounts as you work northward 
into central IN. All of the precipitation should transition over to 
all rain by late in the day into Saturday night and into Sunday. 
Most of the precipitation should be out of the CWA by Sunday 
evening. 

Surface high will build in behind the departing system and a cold 
front Sunday night into Monday. Another round of colder air will 
work into the area with lows in the mid 20s Monday morning and highs 
in the mid/upper 30s on Monday with mainly dry conditions during the 
day. 

The next impactful system looks to arrive Monday night into Tuesday 
with better chances of most of the area seeing some snow. The 
challenge in the deterministic models is how much moisture will be 
available and how strong will this system be as it develops over the 
western Gulf Monday and then and then slides over the southeast US 
Monday night into Tuesday. Right now the GFS is the most bullish 
with its 00z run bring the most moisture and potentially higher snow 
amounts while the EURO is keeping most of the moisture on the 
southern and eastern side of the system. 

Weather turns drier but remains chilly from Wednesday into Thursday 
with highs in the low/mid 40s.
