Area Forecast Discussion
National Weather Service Indianapolis IN
209 PM EDT Mon May 28 2018

.UPDATE...
The LONG TERM Section has been updated below.

&&

.SYNOPSIS...
Issued at 206 PM EDT Mon May 28 2018

Relief from hot weather across Central Indiana will arrive for the
work week. High pressure is expected to exit the area as the
remnants of a tropical system over the deep south are expected to
arrive in the Ohio Valley by Tuesday night and Wednesday. This
will bring clouds, some rain and cooler weather for the middle of
the week.

Dry weather is expected to return next weekend.

&&

.NEAR TERM /Tonight/...

Issued at 206 PM EDT Mon May 28 2018

A Hot and Humid air mass was in place across Indiana and the Ohio
Valley. This was associated with high pressure stretching from
the Great Lakes to the east coast. Meanwhile tropical low
pressure was found arriving over the Florida pan handle...pushing
north. Radar Mosaics shows some precip associated with this
feature over Tennessee and Alabama. meanwhile...warm and dry NE
surface flow was in place...with temps in the lower 90s and dew
points in the upper 60s. GOES16 shows some high cirrus clouds
arriving ahead of the tropical system to the south.

Time heights tonight and forecast soundings show a dry column
tonight. GFS and NAM continue to suggest ridging in place aloft
while the system to the south continues its approach. Thus will
just trend toward a increasing cloudiness type forecast
tonight...as high clouds from the south are expected to arrive
with the progression of the tropical system. Cloud cover and
rising dewpoints associated with a arriving tropical airmass
should prevent max radiational cooling. Thus will trend lows at or
above the forecast builder blend.

&&

.SHORT TERM /Tuesday through Thursday/...

Issued at 206 PM EDT Mon May 28 2018

Mainly Dry weather still looks in play for Tuesday. The GFS and
and NAM continue to push the tropical system northward toward the
Ohio Valley. However best moisture still has they to arrive.
Forecast soundings continue to show mainly a dry column with some
convective possibilities in the afternoon. Forecast soundings show
attainable convective temperatures in the mid 80s with moderate
CAPE values over 1300 J/KG. Given this...will start Tuesday out as
dry and try to trend toward chance pops for the
afternoon as convection begins. Will trend best pops across the
southern parts of the forecast area as best moisture and
instability will found there.

On Tuesday Night...GFS forecast soundings begin to show deep
saturation. Good lift appears to arrive as the tropical low is
expected to reach western kentucky and the associated flow aloft
shows a negatively tilted upper trough over Indiana. PWATS surge
to over 1.90 inches. Thus will trend pops higher than the builder
blends on Tuesday night as these features arrive. Given the
expected clouds sand rain...will trend lows at or above the
forecast builder blends.

Wednesday should be a wet day. The GFS and NAm suggest the
tropical low will continue its progression across the state with
ample moisture. Forecast soundings remain deeply saturated while
PWAT rise even more. PWATS surge over 2.00 inches through the day
on Wednesday. Will trend toward 90-100 pops with these favorable
dynamics in place. Also given the expected rain temps should be a
bit cooler than the forecast builder blends. Caveat with tropical
systems...progression could be a bit slower than the model
anticipate. The GFS and NAM often trend to progress tropical
system progress northward faster than what actually occurs. This
being said...a 6-12 hour delay in the progression would not be
surprising.

At this moment the GFS and NAM push the upper system out of the
area on Wednesday night and Thursday. Meanwhile aloft an upper
trough still remains in place and another short wave appears to
approaching from the northwest within the flow. With the departure
of the tropical system...forecast soundings appear to begin to
dry out and show more convective instability by Thursday with
attainable convective temps...steep lapse rates and CAPE over 3000
J/KG. Thus given this...along with possibility of a slower
progression of the tropical system...we will need to keep pops in
the forecast on Wednesday night and Thursday. Will stick close to
the forecast builder blends on Temps at this point due to
uncertainty with the progression.

&&

.LONG TERM (Thursday night through Monday)...

Issued at 210 PM EDT Mon May 28 2018

Forecast confidence is high through Friday night, but lower
Saturday through Monday.

The GFS and European models are similar in their handling of a
frontal passage early in the period. This builds confidence the
consensus forecast will be good, with possible temperature errors
mostly 2 degrees or less and POP errors mostly under 20 percent.

Starting Saturday, the GFS and European have significant differences
in how they deal with a second frontal system. This leads to
different precipitation forecasts, with the GFS drier. Currently it
is best to have at least some of rain most of the time from Saturday
through Monday. A more definite forecast may have to wait until late
in the week.

The weather will be mostly clear into Tuesday as the remains of
Alberto slowly approach. Mid level clouds could develop tomorrow.
Expect winds mainly east at 7 knots or less. &&
