Area Forecast Discussion
National Weather Service Indianapolis IN
712 PM EDT WED MAY 11 2016

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

&&

.SYNOPSIS...
Issued at 312 PM EDT Wed May 11 2016

An active weather pattern will continue to impact central Indiana
as several fronts moving through will bring showers and
thunderstorms to the area. Cooler temperatures will move in for the
end of the week and hold sway for the next several days with a
Canadian upper low bringing cooler northwest flow.

&&

.NEAR TERM...(This Evening and Tonight)

Issued at 312 PM EDT Wed May 11 2016

A line of thunderstorms currently across western Illinois moving
east will arrive in western Indiana this evening and cross the state
from there. Also there has been some scattered storm development
across northern Kentucky but for the most part CIN over that area
and across our southwestern counties is impeding its development. Hi
res models are in disagreement over how the Illinois line will
progress and develop, with the latest HRRR splitting the line and
taking the southern part across the southern part of the forecast
area starting around 23z and the northern part dissipating. The RAP
brings showers and storms into the area later (around 1-3z) and then
both show more widespread showers across the area 6-9z.

Hard to distinguish severe potential with timing differences
impacting available instability, but if the HRRR solution comes to
fruition expect some storms in the southwestern counties to be
severe with damaging winds and large hail with the best timing
23-3z. At this time favor this solution but think the northern
storms could hold together to impact at least the northwest
counties. Instability is a bit less there but as long as inflow
doesn't get cut off because of the southern storms could see isolated
severe there as well with similar timing.

&&

.SHORT TERM...(Thursday through Saturday)

Issued at 312 PM EDT Wed May 11 2016

A cold front will move through central Indiana during the day on
Thursday, closely followed by an upper shortwave. This will keep
chances for thunderstorms in the forecast through the day. In the
southern counties could see likely pops remain through the day, but
the eastern counties could have time to destabilize some before the
cold front arrives and thus have the highest pops there from 18z-0z
and think upgrade to slight risk for this area makes sense.

Held onto rain chances in the east early Thursday night with the
upper wave possibly not quite out of the area yet depending which
model you look at. By late Thursday night have the entire area dry,
and this lasts through much of the day Friday with high pressure
sliding from the plains south of the area.

Late Friday afternoon/early Friday evening another cold front
approaches from the northwest and moves through the area during the
overnight hours. Forcing with the front looks good enough to include
likely pops during the night for most of the area. MUCAPES of a
couple hundred could be maintained ahead of the front so included a
slight chance for thunder as well. Saturday kept a slight chance for
showers in the east given the cyclonic flow.

Temperatures may not get out of the 60s on Friday after the first
cold frontal passage, and the second frontal passage on Friday night
will usher in even colder air with only 50s expected on Saturday.

&&

.LONG TERM...(Saturday night through Wednesday)

Issued at 1:50 PM EDT Wed May 11 2016

The initialization from the regional software will be used with high
confidence through Monday night.  Starting Tuesday confidence
remains fairly high for precipitation, but drops sharply for
temperatures.

There is good agreement between a wide range of forecast techniques-
until Tuesday. Since the Regional forecast is a blend of these
methods it ought to work well.

Starting Tuesday there are major disagreements in the location of a
front that will affect the area. This is especially evident between
the GFS and European systems. The various solutions all support the
concept of a wet period, even if for different reasons. Until there
is better correspondence on front location the temperature forecast
is quite uncertain.

&&

.AVIATION...(Discussion for 120000Z TAF issuance)
Issued at 712 PM EDT Wed May 11 2016

An area of showers and thunderstorms over over Illinois and extreme
western Indiana will move on to the east.   Beleive most of the
activity over central and northern sections will weaken and thus
went mainly vcts overnight with the exception of KBMG where there
may be a few hours of tempo thunderstorms there.  Even so...TAF's
will remain mostly VFR overnight.

Model soundings indicate Ceilings may become MVFR towards daybreak
Thursday and went mostly MVFR Ceilings Thursday morning.  A cold
front will move through mid to late morning.  TAFS should be mostly
VFR from midday Thursday on with more mixing.  May see some partial
clearing late Thursday as drier air spreads in.

Winds will be from the south less than 10 knots overnight...except
higher near thunderstorms.   Winds Thursday will be southwest early
in the morning and west rest of the day around 10 knots.
