Area Forecast Discussion
National Weather Service Indianapolis IN
644 PM EDT Tue Apr 3 2018

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

&&

.SYNOPSIS...
Issued at 624 PM EDT Tue Apr 3 2018

Thunderstorms, some strong or severe, will lift east and northeast
across central Indiana tonight along and ahead of cold front. Behind
the cold front, colder and mostly dry conditions will filter.
However, there will be small chances for showers Thursday afternoon
through Friday night. After that, the next chance of rain showers
will be by Sunday night. A few snowflakes may mix in at times
Sunday night and next week over all or parts of central Indiana.

Previous discussion follows...
Issued at 337 PM EDT Tue Apr 3 2018

Storms continue to move through the forecast area across the eastern
counties, with some new weak development to the east. More
development is expected ahead of a cold frontal passage tonight,
with severe potential continuing until this front passes. After
that, below normal temperatures will return and drier conditions
with small chances for showers Thursday into Friday and then Friday
night. A mainly dry weekend is expected, but more precip chances
arrive to end the weekend and start the work week, with some
potential for snow with the below normal temperatures.

&&

.NEAR TERM /Tonight/...
Issued at 624 PM EDT Tue Apr 3 2018

Broken line of thunderstorms was moving northeast across central
Indiana early this evening. The line and area of storms has not
produced widespread severe weather but still has the potential for
all severe types including a tornado or two. Will keep the Tornado
Watch going through 8 pm. the severe threat may last shortly after
that as the storms were moving into an instability ridge with CAPEs
to 1800 J/KG over central Illinois last hour.

Previous discussion follows...
Issued at 255 PM EDT Tue Apr 3 2018

Threat for severe weather will continue this afternoon. First wave
of thunderstorms is moving into the eastern forecast area, and some
of these are strong to severe in the south where instability has
built up behind the warm front.

The warm front will continue to push north across the area during
the remainder of the afternoon ahead of deepening low pressure. This
will bring instability to the entire area. Low levels continue to
have good shear.

A line of storms developing near the cold front back across Illinois
and Missouri will continue to develop as it moves into the unstable
air. Thus the threat for severe weather, including tornadoes, will
continue as this line moves in late this afternoon into early
evening.

Will allow PoPs to become high once again by late this afternoon and
then continue them into early evening as the front moves through.
Will also continue to mention severe threat.

High moisture content in the atmosphere will keep the threat for
heavy rain around. This combined with the saturated ground will keep
flooding as an additional threat into the evening as well.

Strong cold advection will occur tonight behind the low. This will
keep gusty winds around through the night. Some weak forcing from
the wrap around behind the low will bring some low chances for
precipitation across the north late tonight. Thermal profiles show a
mix of rain and snow is possible.

The model blend looks good for low temperatures tonight.

&&

.SHORT TERM /Wednesday through Friday/...

Issued at 337 PM EDT Tue Apr 3 2018

Forecast focus is on cooler temperatures early and then quick moving
system Thursday. Generally stuck with initialization. As the upper
wave associated with today/tonight's system moves out on Wednesday
morning could see some brief snowflakes in the northwest counties
through midmorning before high pressure builds in and the upper wave
exits. MAV and MET differ a decent bit in highs for the day, but
given the cold advection aloft expect temperatures to struggle to
climb and thus dropped a bit from the blended initialization for
highs in the upper 30s north to lower 40s south.

High pressure will then build in across the area and bring dry
weather until Thursday afternoon. The cooler temperatures will
continue Wednesday night with lows in the mid to upper 20s.

Warm advection could impact the southern counties on Thursday. A
warm front will form up and stretch across the forecast area and
should see chances for showers in the afternoon on isentropic lift
across the front. This will keep the highest pops in the northern
counties as models are in pretty good agreement that the front will
set up somewhere in the middle of the forecast area. A surface low
will move along the front quickly through the area and bring in some
dry conditions by Friday morning.

The plains part of the system may continue to hang around south of
the area, and this could bring shower chances back by Friday
afternoon.

&&

.LONG TERM /Friday night through Tuesday/...

Issued at 337 PM EDT Tue Apr 3 2018

Friday night a front to the south of the area will keep some forcing
over the southern counties, but cold advection will be in place as
well. Thus if any precip occurs could see a transition from rain to
snow during the night. Saturday into Sunday high pressure traverses
the area and should see dry conditions. By Sunday afternoon the next
system approaches to bring precip chances to the area. Models have
some disagreements in timing of this system though so confidence in
timing of precipitation from Sunday night onward is low, however
confidence that some precipitation will happen between Monday and
Tuesday is fairly high.

Also of note during this time period is the below normal
temperatures from the steadfast upper trough over the eastern U.S.
Relatively high confidence in this based on the agreement of
ensemble upper patterns.

Given the below normal temps, could see some potential for snow late
Friday night, as well as during the overnight hours Sunday, Monday
and Tuesday. Too high of uncertainty in timing and precip type to
mention any accumulation, but there will be mention of snow in
the forecast.

&&

.AVIATION (Discussion for the 040000Z TAF Issuance)...
Issued at 644 PM EDT Tue Apr 3 2018

Convection along and ahead of an advancing cold front will move east
of the terminals after 02z. Good confidence the terminals will see
MVFR or worse showers until then. Lesser confidence in thunderstorms
but enough for tempo groups. After that, good confidence in MVFR or
worse ceilings through the night. Do not expect an improvement to
VFR til after 15z.

The gusty winds will will be an issue tonight and into Wednesday
morning. Should see gusts from 25 to 30 knots or so through the
night and a little lower after 12z. Wind direction will shift from
southwest to northwest behind the front.
