Area Forecast Discussion
National Weather Service Indianapolis IN
1252 PM EDT Tue Apr 3 2018

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

&&

.SYNOPSIS...
Issued at 246 AM EDT Tue Apr 3 2018

A low pressure system is expected to move through the area this
afternoon and evening. Another weaker frontal system will move
through around Thursday. A third frontal system may affect the area
early next week.

&&

.NEAR TERM /Today and Tonight/...
Issued at 1145 AM EDT Tue Apr 3 2018

Main band of thunderstorms has shifted to the northern forecast
area. Warm front remains across the far southern forecast area where
temperatures have risen into the mid to upper 60s. Some clearing has
occurred near the warm front.

Additional convection is developing ahead of the warm front. Have
adjusted PoPs to reflect these trends, and have adjusted hourly
temperatures as needed.

Models still show warm front making good progress through the area
as low pressure deepens as it moves in. However there is some
concern about how the cooler air will respond since it was
reinforced by outflow from the morning convection.

At any rate severe threat continues with first the warm front then
the cold front as it moves through. If cells fire up in the warm
sector ahead of the cold front they could interact with strong 0-1km
helicity to produce tornadoes. SPC has us in a hatched area for
tornadoes and this looks good. Hail is also a threat as reports of
near severe hail have already been received. Will continue to
monitor closely.

Will keep flood warnings going with new cells developing.

Previous discussion follows...

Area of rain and thunderstorms currently over the southern and
central zones associated with a strong warm advection pattern on the
nose of a low level jet. Expecting fairly widespread rain and
thunderstorm activity to continue and drift slowly north through
about the midday hours today as the low level jet remains anchored
over the area.

Last evening's upper air indicates lapse rates were not particularly
steep at this time, but short term model guidance suggests steeper
lapse rate will probably begin bleeding into the area after sunrise.
As a result, risk of hail may be muted somewhat until after sunrise.

Lift and low level jet may tend to weaken towards the midday hours
today, so activity may tend to diminish around that time.
Questionable how far north warm front will get today, depending on
how much morning convection lingers, but finer scale model data
suggest front may make it into the central zones this afternoon.

Appears cold front will be approaching the western border zones
around 032300Z, passing east of the area by 040300Z. Most of the
model guidance suggests a line of convection will be associated
with this feature. Appears best threat for severe convection will
be later this afternoon and early evening, as steeper lapse rates
will be in place by then, along with strong deep layer shear.
Environment appears favorable for potentially some supercell
development ahead of the cold front in the warm sector later this
afternoon and early evening.

Convection currently beginning to shift off to the north of the
current Flood Watch. Will probably do some last minute adjustments
to the watch closer to issuance time. Appears there will be some
threat for heavy rain over the central zones through the morning
hours as the nose of the low level jet will be focused in this
area.

Severe threat expected to end with the passage of the cold front
this evening, along with the higher PoPs. Will keep some chance
PoPs going later in the night for potential wrap around activity.
May be cold enough for mixed precipitation in the north, but any
QPF looks to be very light.

Based on low level thicknesses and questions revolving around how
far north warm front will get today, will bump the GFS MOS highs
today down a category in the north. Will also cut about 3-5 degrees
off of the guidance lows tonight.

&&

.SHORT TERM /Wednesday through Thursday night/...
Issued at 246 AM EDT Tue Apr 3 2018

Dry conditions expected Wednesday and Wednesday night as high
pressure drifts through. Model guidance suggests a disturbance will
move through the area Thursday and Thursday night. Will go with some
chance PoPs for showers at those times.

Progged low level thicknesses suggest the GFS MOS highs for
Wednesday and probably on the warm side. Will bump the guidance down
a category in that period. Remainder of periods look Ok for now.

&&

.LONG TERM /Friday through Tuesday/...

Issued at 357 AM EDT Tue Apr 3 2018

Models continue to be in close agreement during the period. The
challenge to monitor for the next few days is precipitation type
and temperatures.

Ensembles show that region will be under west-northwest flow aloft
through the period. First mid/upper level trough will move
southward into the Upper Great Lakes and through the Great
Lakes/Upper Ohio Valley. This will bring a cold front southward
through Indiana right at the start of Friday, accompanied by gusty
northwest winds. A cold day for April for sure. Some scattered
light rainshowers will be around on Friday moving out by Friday
evening. Cold high pressure is then expected to move in keeping
temperatures below normal.

The high will move off to the east as the next low pressure system
moves east-southeast from the Northern Rockies. Models may be a
bit fast with precipitation with this system bringing on when we
still have southeast winds from recycled dry air from the high
over the east coast. But, precipitation will move in by Sunday
evening as rain at this point. So, will keep a low confidence on
timing of precipitation for late Sunday into Monday at this time.

&&

.AVIATION (Discussion for the 031800Z TAF Issuance)...
Issued at 1252 PM EDT Tue Apr 3 2018

IFR conditions expected at times through the period. Scattered to
numerous convection through 01Z or so. Gusty southwest winds
developing this afternoon.

First line of convection will be moving through at valid time, and
additional scattered convection will continue to develop through the
afternoon. A line of convection will move through during the 22-01Z
time frame. Within convection expect IFR or worse conditions.
Outside convection most sites will remain MVFR.

After the cold front moves through this evening MVFR and IFR
conditions will rule through the overnight, with MVFR Wednesday
morning.

As the warm front moves north this afternoon winds will become
southwest and gust to around 30kt. Behind the cold front winds will
become northwest.

Confidence is high that convection will occur, but confidence is low
to medium on timing.
