Area Forecast Discussion
National Weather Service Indianapolis IN
1138 PM EST Wed Nov 14 2018

.UPDATE...
The AVIATION section has been updated below.

&&

.SYNOPSIS...
Issued at 349 PM EST Wed Nov 14 2018

Dry weather will continue for a few more hours, but moisture is
quickly building into the southern portions of central Indiana as
a low pressure system moves closer to the Tennessee Valley. The
system will bring wintry precipitation to all of central Indiana
tonight into tomorrow. Snow and ice accumulations will make the
Thursday morning commute hazardous. The system will then exit
Thursday evening, and dry conditions will then prevail into the
weekend. At that point, a cold front will bring the next chance
for light snow and rain showers over the weekend.

&&

.NEAR TERM /Rest of Tonight through Thursday Evening/...

Issued at 944 PM EST Wed Nov 14 2018

Added more sleet to the forecast this evening as reports come in of
predominantly sleet across the south. Some snow and light
rain/freezing rain is also falling. Tweaked PoPs but the overall
trend looks good, as the initial edge of radar echoes isn't reaching
the ground due to the dry low levels.

Warm surge of air aloft still looks to impact the southeast forecast
area the most per the latest RUC analysis and forecast. Thus for now
have made no significant changes to ice/snow amounts. Will continue
to monitor closely.

Previous discussion follows...

Current water vapor satellite shows an area of low pressure
rotation over southern MO/northern AR, which will be the focus of
the near and short term periods. The imagery also shows an influx
of moisture into southern Indiana. So, the dry conditions will
only continue through the evening hours before the air column
becomes saturated and precipitation starts falling.

Depending on how quickly the lower levels saturate and the exact
start time of the precipitation will make a big difference in
precipitation type with this system. Initially, there could be
some light snow showers if the lower levels are able to saturate
before Thu 00Z. But, if precipitation starts any later than that,
precipitation could quickly change to a wintry mix of snow, sleet,
and freezing rain as forecast soundings trend toward a warm nose
in the mid levels. By midnight though, that wintry mix should be
the predominant precipitation type through Thursday morning. As
temperatures warm even further through the day on Thursday,
freezing rain and rain will become the prevailing precipitation
types through the remainder of the storm system.

Due to the increase in warmer air aloft, snowfall totals have been
reduced a bit and ice accumulations have been increased. So,
latest snow totals are now trending toward less than an inch
across the southeastern third of the forecast area to 1 to 1.5
inches over most of the area, and up to 3 inches across the far
western counties. Meanwhile, ice accumulations are now trending
closer to a tenth of an inch across the southeast quadrant, then
gradually decreasing northwestward.

As the system pushes east/northeastward on Thursday,
precipitation chances will diminish from west to east with the
western counties dry by Thu 23Z. Elsewhere, light rain and
freezing rain will linger across the eastern counties until Fri
06Z. After that, precipitation should be out of the entire
forecast area.

&&

.SHORT TERM /Thursday Night through Saturday/...

Issued at 349 PM EST Wed Nov 14 2018

After Fri 06Z, the aforementioned system will quickly move off to
the northeast U.S. and dry conditions will return for most of the
short term period. In addition, weak warm advection will bump
daytime highs up a bit on Friday and Saturday into the upper 30s
(north)to low to mid 40s (central and south).

Saturday, precipitation chances will start increasing again from
the northwest as a cold front approaches central Indiana.
Precipitation will initially start as rain, then transition to
snow, but accumulations will be minimal.

&&

.LONG TERM /Saturday night through Wednesday/...
Issued at 255 PM EST Wed Nov 14 2018

The extended timeframe begins with the forecast area under the
influence of a broad upper trough aloft and a frontal boundary at
850mb across the northern portion of central Indiana. The main
weather- maker during the extended portion of the timeframe rest
with the approach of an upper trough rotating through the broad
upper cyclonic flow. The GFS swings the effects of this system
through a bit faster than the ECMWF solution. Because of this
disagreement, decided to stick close to the regional
initialization blend which trended toward the slower ECMWF
solution. A slight chance for snow across the northern half of the
area is in place to start the timeframe. Then precipitation
chances increase and overspread the region during the day on
Sunday into Sunday evening...with precipitation coming to an end
from northwest to southeast Sunday night. Snow to start gives way
to rain over much of the area on Sunday as temperatures warm. The
northwest portion of central Indiana looks to see rain mix with
snow Sunday afternoon before much of the area returns to all snow
Sunday evening. If any accumulations were to occur...they look to
be light.

Monday looks to be the coolest day of the extended with highs from
the middle 30s to near 40 degrees. Then a gradual warming trend
takes root with highs on Wednesday from the lower 40s north to
near 50 degrees south.

&&

.AVIATION (Discussion for the 150600Z TAF Issuance)...
Issued at 1138 PM EST Wed Nov 14 2018

Poor flying conditions expected through the period, with a wintry
mix of precipitation into the early daylight hours of Thursday.

Ceilings will lower quickly into the IFR range with visibility also
lowering some. Main precipitation type at KIND/KBMG looks to be
sleet and freezing rain, but some snow may also mix in, especially
toward 12Z. At KLAF/KHUF, snow and some sleet look to be the primary
precipitation types. At those locations, visibility may dip into the
IFR range at times as well.

Precipitation will diminish Thursday morning, with scattered snow
showers continuing into the afternoon. Ceilings will remain IFR or
lower.
