Area Forecast Discussion
National Weather Service Indianapolis IN
701 AM EDT Tue Jun 12 2018

.UPDATE...

The Aviation section has been updated below.

&&

.SYNOPSIS...
Issued at 451 AM EDT Tue Jun 12 2018

With a frontal system still in the area...periodic shower and
thunderstorm chances persist bringing with it the possibility of
additional heavy rainfall. A cold front eventually pushes south
and east of the area by Wednesday night. High pressure moves in
behind the front...keeping the forecast area dry through the
weekend.

&&

.NEAR TERM /Today and Tonight/...
Issued at 451 AM EDT Tue Jun 12 2018

Focus for the near term continues to be on the heavy rain threat.
Showers and storms over central Illinois continue to push our way
early this morning. Current storm track trends will have it
passing over areas that have been impacted by previous heavy rains
on Sunday and Monday. Thus, decided to expand the Flash Flood
Watch further north and east and also now until 1800Z. Current
flash flood guidance illustrates that for some areas within the
watch it would only take around an inch in an hour or an inch and
a half in three hours to produce some flash flooding issues. Over
the southwest corner of Knox County it is even lower than that!
High chance POP continues to start the period over southwest
portions of the forecast area, where current radar trends and
short-range model solutions forecast the the heaviest of the
precipitation to fall. Models also expect this morning convection
to start to wane by 15-1700Z. Now, most projections have
additional thunderstorms redeveloping across the area by 19-2000Z.
However, it should be noted that model solutions showed the same
for Monday and that did not pan out well. Thus, confidence is not
high in the afternoon redevelopment as early as the models
project. This will be something to keep an eye on. Shear does look
a bit better for tomorrow, so the potential for more organized
convection is better. Temps will again be highly dependent on
impacts from convection.

&&

.SHORT TERM /Wednesday through Thursday Night/...
Issued at 451 AM EDT Tue Jun 12 2018

A cold front approaches the forecast area from the northwest to
begin the period and will push southeast through the area
Wednesday morning through the afternoon...shunting precipitation
chances further south. High pressure then filters into the region
behind the front...keeping the forecast area dry through the
remainder of the period.

While high temperatures are still forecast to be above normal
after the frontal passage, it should feel more comfortable than
earlier days this month as winds veer from northwest to out of the
northeast to east by Wednesday night...dropping
dewpoints/humidities to a more acceptable level for Wednesday
evening and Thursday.

&&

.LONG TERM /Friday through Tuesday/...
Issued at 325 AM EDT Tue Jun 12 2018

Long term model guidance is now pushing the center of the upper
level ridge into the lower Ohio Valley late this week and into the
weekend, before dropping it back to the south and southwest early
next week and allowing the ring of fire convective zone back into
the region for the start of the work week.

Will remove some patchy slight chance pops placed in by the model
blend and keep things dry through Sunday night. Chances for storms
return Monday and remain into the rest of the period.

Temperatures will be quite warm with the ridge right overhead and
will likely reach 90 across much of the area on some days.

&&

.AVIATION /Discussion for the 12/12Z TAFs/...
Issued at 700 AM EDT Tue Jun 12 2018

Predominantly VFR through the period, outside of any temporary
restrictions in showers and storms.

Scattered storms are slowly making their way into the area, and
will include vicinity mentions at most sites today. Additional
redevelopment is possible this afternoon but conditional. This
prevents a more explicit inclusion.

Winds throughout the period will be 10KT or less, generally
becoming more southwesterly with time.

No significant obstructions to visibility expected outside of
showers and storms.

.IND WATCHES/WARNINGS/ADVISORIES...

Flash Flood Watch until 2 PM EDT this afternoon for INZ043-044-
