Area Forecast Discussion
National Weather Service Indianapolis IN
834 PM EDT Fri Mar 25 2022

.Mesoscale Update...
Issued at 834 PM EDT Fri Mar 25 2022

Scattered convection is continuing across central Indiana this
evening. Thanks to some CAPE and steep low level lapse rates,
convection has grown enough to have some lightning in it at times.

This stronger convection is bringing down wind gusts over 50 mph in
a few locations.

The convection should weaken in the next couple of hours as
heating is lost and lapse rates diminish.

&&

.Short Term...(This Evening through Saturday Night)
Issued at 259 PM EDT Fri Mar 25 2022

* Cold and unsettled weather through the beginning of the weekend
* Chance for snow showers this evening into Saturday
* Scattered snow squalls possible this evening through Saturday
  morning

Another early Spring day where Winter is winning the battle
currently. Gray...damp and raw as a weak upper level wave drifts
across the region and produces a few light showers and pockets of
drizzle. 18Z temperatures ranged from the upper 30s to the mid 40s
but brisk westerly winds were making the air temps feel colder.

Today is certainly not an award winner in the weather department and
the next 36 hours will reinforce that winter is not giving way
across the Ohio Valley easily or willingly. A potent upper level low
dropping through the upper Midwest currently will serve as the
catalyst in tandem with a cold front set to swing through the region
late today to bring a resurging blast of Arctic air into the weekend
along with a solid threat for snow showers this evening into
Saturday with some potential for a few squalls late tonight. Lot to
discuss.

Upper level flow pattern across the country highlighted by a ridge
over the Intermountain West with a downstream broad trough
encompassing much of the eastern half of the U S. The aforementioned
upper low to our northwest will only serve to enhance and amplify
the flow aloft with a deep trough carved out across the region by
Saturday. Upper level flow will begin to modify by late day Saturday
as the trough axis lifts out into New England...but the Ohio Valley
and Great Lakes will remain in a NW flow regime with hints of
lingering cyclonic flow that will likely limit any substantial
clearing across much of the region until Saturday night.

For the next few hours...pockets of drizzle in tandem with light
rain showers will continue...especially across the northern half of
the forecast area. Current satellite imagery suggests that an axis
of clearing ahead of the cold front across west central illinois may
manage to clip the lower Wabash Valley late afternoon otherwise
skies will remain cloudy for the remainder of the day. The arrival
of the front after 21-22Z will initiate renewed scattered convection
with rain showers perhaps mixing with a bit of graupel with any
elevated cores. Even possible for a few lightning strike over the
northern Wabash Valley but expect most of that to remain to the
northwest of the forecast area. Wind gusts will increase along and
immediately behind the frontal passage late today into the early
evening with peak gusts at 35 to 40 mph.

Once the initial axis of scattered convection with the front
passes...there will be a general lull with just a few showers into
the first half of the evening. Potential even there for a brief
period of mainly clear skies across the southwest half of the
forecast area before clouds increase again later in the evening as
the upper low begins to influence. The thermodynamic setup then
becomes critical as the impressive dynamics aloft associated with
the upper low interact with favorable conditions in the boundary
layer for localized convective bursts of precip which will
increasingly trend towards snow as the lower levels cool. While not
the most impressive setup...lapse rates through 700mb will peak at 7-
8 C/km in tandem with a noted area of low level CAPE. Adding in the
intense cold advection immediately behind the front...these factors
will interact to produce scattered snow showers and most likely
squalls as well with gusty surface flow from late evening through
much of the overnight as the upper low pinwheels through the lower
Great Lakes. The best focus for snow showers and squalls will be
across the northeast half of central Indiana from late evening into
the predawn hours with lighter snow showers continuing into Saturday
morning.

Road impacts will be mitigated to some degree by how warm the ground
temperatures have been in recent days...but surface temps set to dip
into the upper 20s and lower 30s will cause slick spots in some
locations...especially wherever squalls swing through and produce
rates briefly heavy enough to overwhelm marginal surface temps. Most
accumulation though will focus more on grassy and elevated surfaces
and likely no more than a dusting to perhaps a few tenths of an
inch. Wind gusts will occasionally approach 40mph or slightly
higher at times tonight which will lead to drastically reduced
visibilities in tandem with any heavier snow shower or squall.

Scattered snow showers will be ongoing Saturday morning...primarily
again across the northeast half of central Indiana with lingering
forcing and cyclonic flow aloft on the back side of the upper low.
While the moisture shallows substantially throughout the day
Saturday...have some concerns that the presence of continued steeper
low level lapse rates will be enough to maintain at least the threat
for scattered light snow showers or perhaps flurries well into the
afternoon before diminishing...mainly along and NE of Interstate 74.
With surface temps above freezing...do not expect any impacts during
the day but likely to be snowflakes flying around to some degree.
Clouds may begin to break up across the southwest on Saturday with
more substantial clearing Saturday night from west to east as the
upper low pulls away and a strong high pressure ridge builds down
out of the upper Midwest. After a brisk Saturday...winds should
finally begin to relax as well Saturday night.

Temps...the passage of the cold front and strong upper low will
bring a fresh surge of late season Arctic air that will remain
through the weekend. Lows will drop in the upper 20s and lower 30s
over much of the region tonight with only modest recovery Saturday.
Low level thermals support undercutting warm end of guidance by a
few degrees as highs range from the mid 30s and lower 40s will be
common. First of two very chilly nights for Saturday night as lows
likely drop well into the 20s. While widespread vegetative growth is
not quite far enough along to warrant the onset of the Spring
Frost/Freeze headline season...there has been some localized growth
in spots that would be susceptible to the subfreezing temperatures
expected at night this weekend.

&&

.Long Term...(Sunday through Friday)
Issued at 259 PM EDT Fri Mar 25 2022

The long term period will start with mostly sunny and dry conditions
with below normal temperatures as the area sits under upper NW flow
and a surface high. NW flow aloft will continue into the beginning
of next week, continuing the below normal temperatures.

A weak warm front looks to creep northward into the area that could
bring some light rain for Monday night into Tuesday. Confidence is
low on precipitation being produced by this system as upper ridging
and subsidence moving in at the same time should act to stabilize
the column. Getting later into the day Tuesday though, forcing
along the front seems to strengthen some as well as an increase in
moisture which will improve the chances for light precipitation.
The upper ridge will continue eastwards towards midweek, then
placing central Indiana under SW flow. This will bring in both WAA
and moisture advection for Wednesday leading to highs that day
into the 70s. An upper trough and surface low pressure system will
be pushing eastward into the area beginning midweek as well,
leading to likely PoPs late in the day Wednesday and overnight.
Models are showing PWATs near climatological max with this system
which may lead to some flooding issues across the area. There is
also a chance for stronger to potentially severe storms late
Wednesday to Wednesday night as winds strengthen and the
associated cold front swings through the Mississippi Valley.
Better conditions for stronger storms are more likely to occur
further SE but depending on how the low ends up tracking, enough
instability, winds, and deep moisture could get into central
Indiana so will have to monitor this system over the coming days.
It is still too soon to determine any details at this time.
However, did bump up thunder chances slightly for late Wednesday
as guidance hardly included any. Temperatures will again turn
cooler, and near normal, behind the passage of the cold front.
Wrap around moisture on the backside of the exiting low will help
to continue a chance of PoPs into the end of the week.

.Aviation...(00Z TAF Issuance)
Issued at 701 PM EDT Fri Mar 25 2022

IMPACTS:

- Scattered light showers at times into the overnight
- Potential for snow showers and squalls late tonight into Saturday
morning
- Wind gusts in excess of 30kts this evening and overnight
- MVFR ceilings at times for the northern sites

DISCUSSION:

Scattered rain showers are currently moving through the region as a
strong upper-level low advances southeastward from the upper
Midwest. A cold front accompanies the upper low and strong cold air
advection will allow for snow to mix in with the rain at times
tonight. The post-frontal showers / snow showers are convective in
nature, so wind gusts in excess of 35kts are possible within the
downdrafts as momentum from aloft mixes downward. Gusts over 20kt
are expected in all locations regardless of shower activity. MVFR
ceilings will primarily occur in northern sites overnight.

Gusty northwesterly flow will continue into Saturday as the upper
low pulls away. Unstable air in the wake of the upper low will allow
for a few residual snow showers during the day before diminishing in
the afternoon. MVFR ceilings will continue into the first half of
the day, before rising to VFR by Saturday evening.
