Area Forecast Discussion
National Weather Service Indianapolis IN
633 PM EST Tue Jan 10 2017

.UPDATE...
The NEAR TERM Section has been updated.

&&

.SYNOPSIS...
Issued at 251 PM EST Tue Jan 10 2017

A strong area of low pressure will provide windy conditions this
evening as well as bring rain and a few rumbles of thunder with a
cold front moving through. The front will meander north and south
across the area into the weekend, bringing more rain at times. As
colder air works its way into the area late in the week, freezing
rain will become an issue, especially Friday and Saturday.

&&

.NEAR TERM.../Rest of This Afternoon and Tonight/
Issued at 633 PM EST Tue Jan 10 2017

Main issue for the early evening update is to add more counties to
the portion of the wind advisory out until 03Z across northern
counties. Now have the entire northeast half of the forecast area
in the advisory until 03Z including the majority of the Indy
metro.

Frontal boundary currently tracking across the northern Wabash
Valley at 2330Z with an intensifying line of convection with
thunder. Could see stronger wind gusts to 50-55mph if not
slightly higher within the line over the next couple hours. Higher
gusts do not drop off immediately behind the front...hence the
idea behind the wind advisory extension over the northeast half of
the forecast area.

Previous discussion follows.

Windy conditions continue across central Indiana this afternoon,
with gusts over 45 mph reported at some locations. As strong low
pressure moves into the upper Great Lakes, it will drag a cold front
through the area this evening.

The front plus isentropic lift with a strong low level jet will
continue to generate rain at times later this afternoon and into mid
evening. Will go likely PoPs late this afternoon most locations and
across the eastern forecast area after 00Z, with chances ending
everywhere by midnight as drier air works in behind the front.

Wouldn't rule out an isolated thunderstorm, but believe coverage
will be too low to mention.

Winds will continue to be the biggest issue into the evening with
the tight pressure gradient and strong low level jet. Am concerned
that strong cold advection and pressure rises across the northern
forecast area this evening could bring down stronger winds longer
than previously expected.

Thus will extend in time the wind advisory for roughly the northern
half of the forecast area a couple of more hours (til 10 PM). Will
highlight potential of winds over 50 mph there. Elsewhere it looks
like winds will diminish enough to keep 8PM expiration time, but
will have to watch closely.

&&

.SHORT TERM.../Wednesday through Friday/
Issued at 251 PM EST Tue Jan 10 2017

Models are close enough that the SuperBlend initialization
was accepted for most items.

The front will be south of the area Wednesday morning, but as upper
flow becomes southwest and a wave forms along the front well to the
west, the front will return north during the day. Increased PoPs
from south to north during the day, with highest PoPs (high chance
to low likely categories) seen in the mid to late afternoon.

Likely or higher PoPs will continue Wednesday night through Thursday
morning with the front remaining in the area and an upper wave
moving along it. Chances will diminish most areas during Thursday
afternoon as the front moves south (and temperatures will fall
during the afternoon).

The front doesn't go too far though and low PoPs will continue
Thursday night into Friday morning across the far south, with low
PoPs spreading north to near the I-70 corridor by late afternoon.
Temperatures aloft will remain warm, but colder air at the surface
will allow for the potential of freezing rain overnight Thursday
night into Friday morning.

Stuck with a model blend for the temperatures.

&&

.LONG TERM.../Friday Night Through Tuesday/
Issued at 251 PM EST Tue Jan 10 2017

Models are close enough that the SuperBlend initialization
was accepted for most items.

Potential for icing, perhaps significant, somewhere across the
forecast area continues during the weekend.

West to southwest winds aloft will keep a flow of warm air across
the area, while high pressure to the north keeps a cold
east/northeast flow at the surface. In addition, ageostrophic flow
thanks to the right rear quadrant of an upper jet may reinforce the
flow of colder air into the area.

However, there still is plenty of uncertainty on where the front
will set up and how much of the colder air gets into the area, with
the models offering different solutions. In these situations, even a
couple of degree difference will have a huge impact on precipitation
type and impacts.

Will thus stick with the initialization, which leads to some icing
most areas, especially overnight Friday night into Saturday morning.
At the moment it looks like Sunday afternoon on should be mainly
rain.

However, keep in mind the forecast will likely change until models
get a better handle on this system.

&&

.AVIATION /Discussion for 110000Z TAF Issuance/...
Issued at 615 PM EST Tue Jan 10 2017

Low ceilings initially will improve to VFR by late evening.
Deteriorating conditions Wednesday afternoon and evening as rain
returns.

Cold front moving into central Indiana early this evening and will
sweep across the region over the next few hours. Scattered showers
impacting the terminals with periodic drops to 2SM with the
heaviest pockets of rain. First wave of showers shifting east of
KIND and KBMG with a quickly developing broken line of convection
along the front. This line will traverse through the region
through 03Z...likely bringing a brief period of heavy rain...
strong winds and reduced visibilities. Will maintain wind gusts in
excess of 30kts at the terminals through the evening and at KLAF
into the overnight.

As low pressure lifts north of the Great Lakes overnight...dry
punch into the region will enable a quick rise in ceilings after
the frontal passage with skies becoming partly cloudy predawn
Wednesday as weak surface ridging moves across the region. The
front will begin its lift back north into central Indiana
Wednesday morning with rain...and much lower ceilings returning
for the afternoon as a stout yet shallow inversion develops.
Expect sub-IFR conditions expanding from south to north 18-21Z
continuing into Wednesday night. Winds will return to southerly
by Wednesday morning.
