Area Forecast Discussion
National Weather Service Indianapolis IN
1001 AM EDT Wed Oct 18 2017

The AVIATION Section has been updated below.


Issued at 340 AM EDT Wed Oct 18 2017

Dry quiet weather can be expected through Saturday across central
Indiana under high pressure. A frontal system and upper northwest
flow will bring chances for showers from Sunday onward, along with
some thunder chances Sunday afternoon and evening.


.NEAR TERM /Today/...

Issued at 340 AM EDT Wed Oct 18 2017

High pressure centered over the eastern third of the U.S. will
keep central Indiana skies clear through the day. Very similar
conditions are expected to yesterday, but warmer by a degree or
two due to starting out a bit warmer than yesterday morning.


.SHORT TERM /Tonight through Friday night/...

Issued at 340 AM EDT Wed Oct 18 2017

Quiet weather is expected with an upper ridge slowly traversing
the central and eastern U.S. High confidence in dry weather and
temperatures increasing a bit each day with very few clouds. No
changes made from initialization.


.LONG TERM /Saturday through Tuesday/...
Issued at 340 AM EDT Wed Oct 18 2017

Dry weather will continue for Saturday before a more active pattern
moves into the region on Sunday. An upper level trough and
associated frontal boundary is expected to move through late Sunday
bringing chances for rain for central Indiana.  A few rumbles of
thunder will be possible Sunday afternoon and evening, but with weak
instability coverage will be limited. Confidence is low for chances
for rain going into Monday and Tuesday with uncertainty on how the
system develops as it moves out of the region. Therefore, keeping
chance POPs in for Monday and Tuesday, but keeping them lower than
initialized consensus.

Above average temperatures are expected through Monday before more
fall like weather returns going into the rest of the work week as
the flow becomes more northwesterly.
