Area Forecast Discussion
National Weather Service Indianapolis IN
1234 PM EDT Sat Apr 22 2017

The AVIATION Section has been updated below.


Issued at 258 AM EDT Sat Apr 22 2017

High pressure to the north and low pressure to the southeast will
work together to dominate Indiana weather through Monday.
A cold front is forecast to approach Tuesday and cross our state
Wednesday. Thursday and Friday the cold front should change into a
warm front that will move north, traversing Hoosierland as it does.


.NEAR TERM /Rest of Today/...

Issued at 931 AM EDT Sat Apr 22 2017

Going to be a rather cool Saturday as clouds will continue with a
northeast wind across the area. Low pressure is down over north
central TN, but a mid/upper level short wave is over northeast KS
which will move southeastward and deepen through this evening.
Radar showing some light rain moving eastward and spreading out
moving into southwest IN. So, occasional light rain mostly south
of I-70 today, but then moving southeast towards evening as the
mid/upper low develops and moves towards TN and the southeast U.S.
Highs no better than low/mid 50s today.


.SHORT TERM (Sunday through Monday night)...

Issued at 258 AM EDT Sat Apr 22 2017

Skies should be mostly clear given excellent model agreement
about a persistent very dry northeast flow. Gradual warming is on
tap as long sunny days modify the air. There is good alignment
between temperature guidance. The consensus forecast should be
accurate to within a couple degrees.


.LONG TERM /Tuesday Through Friday/...
Issued at 326 AM EDT Sat Apr 22 2017

Weak ridge of high pressure will bring dry weather Tuesday.
Wednesday will be wet as low pressure moves across the upper
midwest into the great lakes and a trailing cold front moves
across Indiana.   Thursday will be mostly dry as another
weak high pressure area moves by.  Then another low pressure and
frontal system will move our way Thursday night and early
Friday brining a chance of showers.

Temperatures will be above normal during the long term as a mean
long wave upper ridge remains along the east coast and in fact
temperatures could approach 80 some areas Tuesday and again Friday.


.AVIATION /Discussion for 22/1800Z TAF Issuance/...

Issued at 1224 PM EDT Sat Apr 22 2017

Have been seeing reports of occasional MVFR conditions across
parts of southern IN as broad low pressure over central TN
continues to move slowly east. Northeast surface flow will be the
rule as well today. Mid-high clouds still cover central and
southern IN, and visible satellite imagery shows that clouds have
a convective look to them associated with the broad mid/upper
level circulation from s central IN back through southern IL into
central MO.

Clouds will be sticking around through the remainder of this
afternoon with clearing gradually occurring after 00Z, and mostly
clear by 23/1200Z.
