  flooding. An additional 1 to 2 inches of rain is possible in spots 
  through this evening.

* Some locations that will experience flooding include...
  Washington, Shoals, Loogootee, Montgomery, Cannelburg, West Boggs
  Lake, Indian Springs and Lacy.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

A Flood Warning means that flooding is imminent or occurring. All
interested parties should take necessary precautions immediately.

Area Forecast Discussion
National Weather Service Indianapolis IN
713 AM EDT Sat Aug 1 2020

.UPDATE...

The Aviation section has been updated below.

&&

.SYNOPSIS...
Issued at 144 AM EDT Sat Aug 1 2020

Low pressure over the bootheel of Missouri will push northeast
across Indiana today. This will bring periods of showers...perhaps
an isolated thunderstorm along with chances for heavy rain to
much of the area.

More rain will be expected on Sunday into Monday as a second area
of low pressure crosses Indiana. Dry weather and seasonable
temperatures are expected to return by the middle of the next
work week as high pressure builds across the region.

&&

.NEAR TERM /Today/...
Issued at 144 AM EDT Sat Aug 1 2020

Surface analysis early this morning shows low pressure in place
across SE MO...along with a warm front stretching northeast across
southern Indiana toward Central Ohio. NE surface flow was in
place across Central Indiana ahead of the warm front along with a
very moist air mass as dew points were in the 60s. Radar shows an
area of rain showers ahead of the front. Some of the showers were
producing very heavy rain as seen in Martin County earlier. Aloft
water vapor continued to show a deep upper trough in place across
Wisconsin...Illinois and Missouri. This was resulting in SW flow
in place across Indiana ahead of this broad trough.

The models show only slight progression of the broad upper trough
today. This keeps a warm and moist southwest flow in place aloft.
Meanwhile the surface low over Missouri is expected to trek
northeast along the warm frontal boundary across Central Indiana
through the day. Given these synoptic features...time heights
show plenty of moisture and lift today. Forecast soundings also
show a saturated column with deep moisture in play as pwats soar
to over 2 inches this afternoon. Given our very high pwats and the
nearly tropical air mass in place showers will be very efficient
in producing heavy rain. Isolated heavy rain resulting in flooding
will be possible.

HRRR shows numerous rain showers across the area this afternoon as
the low arrives and pushes across the area. Thus will trend pops
today toward 100 with best chances in the afternoon with the
arrival of the best forcing. Given the plentiful clouds and precip
will trend high temps at or below the NBM.

&&

.SHORT TERM /Tonight through Monday Night/...
Issued at 144 AM EDT Sat Aug 1 2020

A slow progression of the broad upper trough that stretches from
Ontario to Texas is expected the next few days. This cyclonic flow
in place aloft will allow several embedded short waves within the
flow to push across Indiana...resulting in periodic rain showers
through Monday Night.

The first of these short wave within the flow is expected to push
across the area tonight...accompanied by excellent lower and mid
level moisture. Again overnight forecast soundings show pwats over
1.7 inches as these features slowly pass. This wave is suggested
to finally depart the area by Sunday morning. Thus high pops will
be required through at least Sunday morning as these upper level
features pass. Forecast soundings after 18Z on Sunday show some
decrease of moisture within the column...however convective
temperatures are still attainable with a bit of CAPE available.
Thus Pops will still needed to be continued through Sunday
afternoon...but some dry time will be possible. Will stick close
to the NBM temps here.

On Sunday Night through Monday night the GFS and NAM continue to
show the deep pesky trough axis aloft west of Indiana. This will
result in Indiana continuing to be in a favorable position for
precipitation. The upper flow allows yet another surface low to
across Indiana on Sunday night into Monday. Although forecast
soundings show much more dry air in place within the
column...attainable convective temperatures with CAPE over 2000
J/KG remain in place. Thus will to continue to keep pops in place
through Monday Night.

&&

.LONG TERM /Tuesday through Saturday/...
Issued at 325 AM EDT Sat Aug 1 2020

The long term period will start with a chance of showers and
perhaps a thunderstorm as upper level low pressure swings through
the area. Surface high pressure will quickly follow which should
keep things dry mid to late week. A series of subtle disturbances
in weak northwest flow very late in the period will reintroduce
shower and storm chances as the weekend approaches.

Temperatures will be quite mild for the time of year, largely in
the 70s until late in the period, when the low 80s move back into
the area. Blended initialization handled things well and required
only minor adjustments.

&&

.AVIATION /Discussion for the 01/12Z TAFs/...
Issued at 713 AM EDT Sat Aug 1 2020

MVFR or worse conditions through much of the period.

Low pressure will move northeast through the area today, producing
plentiful showers and a few thunderstorms. Conditions will be
restricted at most sites throughout the vast majority of the
period. All sites but LAF are likely to get down to IFR for
several hours, with MVFR ceilings otherwise.

Winds will generally be northeasterly early, becoming northerly
and then northwesterly with time as the low passes. For the most
part, speeds should be 10KT or less.

Obstructions to visibility will be possible during precipitation
but will likely be variable and transient.

.IND WATCHES/WARNINGS/ADVISORIES...NONE.
