...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 215 AM EDT FOR
SOUTHWESTERN KNOX COUNTY...

Earlier this evening, Doppler radar indicated thunderstorms that 
produced heavy rain across the warned area. Up to three and a half 
inches of rain has fallen. Flash flooding is expected to be ongoing.

Flash flooding will remain over mainly rural areas of southwestern
Knox County.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

Move to higher ground now. Act quickly to protect your life.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Please report flooding to your local law enforcement agency when you
can do so safely.

Area Forecast Discussion
National Weather Service Indianapolis IN
642 PM EDT Fri Jul 5 2019

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

&&

.SYNOPSIS...
Issued at 327 PM EDT Fri Jul 5 2019

Scattered thunderstorms will impact central Indiana into Saturday as
an upper level low slides through the lower Ohio Valley. A few
storms remain possible Sunday before high pressure builds south into
the region. With the exception of a threat for scattered
thunderstorms Wednesday and Thursday as a upper level wave passes
through the region...much of next week should be warm and dry.

&&

.NEAR TERM /Rest of This Afternoon and Tonight/...
Issued at 327 PM EDT Fri Jul 5 2019

Areas of convection have fired within the steamy and unstable
airmass so far this afternoon. Focus has been northeast of the Indy
metro and then back to the west in the Wabash Valley. 19Z
temperatures were in the upper 80s and lower 90s and the high
humidity was pushing peak heat indices to around 100.

Focus into the evening remains on additional convective
development...likely heavily influenced by colliding outflow
boundaries. Potential does exist for development to focus over
western counties during the next few hours in particular where
better low level moisture and instability reside currently. That
being said as has been the case the last few days...convection will
be driven by mesoscale features in particular and with boundaries
littered across the area...scattered convection is possible anywhere
across central Indiana into the evening hours.

Storms will largely be subsevere with little to no BL shear but
presence of downdraft CAPE levels approaching 1000 j/kg does support
potential for healthy wind gusts as cores collapse or along surging
outflows. Have already seen wind gusts at 45-50 mph with some of the
storms northeast of Indy. With the slow storm motions and precip
water levels in excess of 1.75 inches...torrential rainfall and
localized flooding will also continue as a primary impact.

Should see convective coverage wane near or just after sunset as has
happened the last few days with the loss of peak heating and deeper
instability. Approach of a weakening upper low from the Missouri
Valley however warrants maintaining a low chance pop all night as
the feature drifts into the lower Ohio Valley by daybreak Saturday.
Could see patchy fog develop late tonight as well in areas where
rain falls.

Temps...another muggy night on tap with most if not all of the area
remaining above 70 degrees all night. A model blend will work fine.

&&

.SHORT TERM /Saturday through Monday/...
Issued at 327 PM EDT Fri Jul 5 2019

Forecast challenges focus on rain and storm chances Saturday and
potentially a lower threat Sunday before a shift to drier and less
humid conditions by early next week.

The aforementioned upper low will drift slowly southeast into the
Tennessee Valley through Saturday night before shifting further away
into the Mid South by late weekend. After being under the upper
ridge...the core of the ridge will shift back west towards the mid
and upper Mississippi Valley which will enable heights to slip back
a bit across the region by Monday.

Saturday will be another day with convection developing by late
morning into the early afternoon across central Indiana. In addition
to the unstable airmass...the presence of slightly better forcing
aloft as the upper low drifts into the Tennessee Valley should
enable a higher coverage to showers and storms by Saturday afternoon
than we have seen the last few days. Have nudged pops up into the
likely category as a result for the afternoon and early evening.
Similar to the last few days...storms will likely pulse in intensity
with limited organization...with gusty outflow winds and torrential
rainfall and flooding serving as the main threats.

Storms will diminish and shift south Saturday night along a weak
frontal boundary. The boundary will remain close enough to the
region Sunday to warrant low chance pops over the region in the
afternoon...especially south of I-70. Most will remain dry however
with low level flow shifting to northerly as high pressure builds
south from the Great Lakes. The high will expand further into the
region Sunday night and Monday with model soundings showing a drier
airmass advecting in from the north and a mid level cap developing.

Temps...another humid day with heat indices peaking in the 90s on
Saturday before less humid air arrives Sunday and Monday. Highs will
remain in the mid and upper 80s into Monday with low level thermals
supportive of a model blend. Lows will fall back into the 60s.

&&

.LONG TERM /Monday Night through Friday/...
Issued at 216 PM EDT Fri Jul 5 2019

Dry weather will bookend this period with chances for some showers
and storms on Wednesday and Wednesday Night.

ECMWF shows ridging in place across Indiana on Monday and
Tuesday...along with surface high pressure...subsidence and weak
but mainly northerly flow. Thus have trended toward a dry forecast
at that time. By Wednesday a quick moving short wave is expected
to approach Indiana from the upper midwest...passing across
Indiana through Wednesday Night and Thursday. This feature will
provide ample upper support and once again pops will be warranted.

On Thursday Night through Friday...the ECMWF shows the upper short
wave departing while strong ridging and high pressure builds
across the American southwest. This will result lee side
subsidence and NW flow across Indiana and the upper midwest. Thus
will trend toward dry weather at that time with highs at or below
seasonal normals.

&&

.AVIATION /Discussion for the 060000Z TAF Issuance/...
Issued at 642 PM EDT Fri Jul 5 2019

GFS LAMP and SREF suggest mostly VFR conditions TAF except for
perhaps in convection through 02z and again after 12z Saturday and
also except for the possibility of some light fog 09z-13z.
Confidence is good in this trend.

Winds will become light and variable or calm after 02z and then
shift to west and north behind a cold front that will move through
after 16z Saturday.

&&

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

This hazardous weather outlook is for central Indiana.

.DAY ONE...This Afternoon and Tonight.

Outlook: Showers and thunderstorms expected this afternoon through
early tonight.

Hazards: Frequent cloud to ground lightning, gusty winds, and
torrential rainfall causing localized flooding.

Timing: Mainly through early tonight.

Discussion: Showers and thunderstorms will develop again today in
the warm and humid air mass. Activity is expected to diminish later
this evening.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

Outlook: Showers and thunderstorms again expected on Saturday into
Saturday night...a small threat for storms Sunday then again
Wednesday and Thursday. Frequent cloud to ground lightning...gusty
winds and torrential rainfall causing localized flooding are likely
with storms.

Discussion: Showers and thunderstorms are expected Saturday and
Saturday Night as an upper level low moves through the lower Ohio
Valley. The system will remain close enough to warrant a threat for
mainly isolated storms Sunday before drier air arrives. Much of next
week should be quiet with the exception of Wednesday and Thursday as
scattered thunderstorms will accompany an upper level wave tracking
through the region.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated at this time...but any storm
reports would be appreciated.
