Update
The near term and aviation sections have been updated below.

Synopsis
Issued at 210 am edt Sun aug 25 2019
large high pressure over the northeastern united states will
continue to provide pleasant weather to indiana today with partly
cloudy skies and pleasant temperatures.

An upper level weather disturbance will push toward indiana from
the mississippi valley tonight. This will result chances for
showers returning to indiana tonight and better chances for rain
on Monday and Monday night.

Another cold front and upper level weather disturbance is expected
to pass across indiana on Tuesday... Bringing more chances for
rain. Dry weather is expected to return on Tuesday night in the
wake of the front.

Dry weather should then return for the remainder of the
week. Temperatures will be below normal for much of the period.

Near term rest of today
Issued at 1029 am edt Sun aug 25 2019
cirrus continuing to stream into the ohio valley this morning in
advance of the upper level wave tracking into the missouri valley.

Dry easterly flow persists with comfortable temperatures. 14z
temps were in the 60s.

Overall forecast for the rest of the day is in very good shape
with only subtle changes needed. Low level flow will begin to veer
by late afternoon with the initial surge of moisture advection
into the lower wabash valley. While overall forcing aloft remains
weak... Isentropic lift will increase and become favorable for at
least a potential for isolated convection over far southwest
counties after 21z and into early evening. Have inserted a low
chance pops there to cover.

Elsewhere across central indiana... Model soundings show dry air
and subsidence lingering through the column today. Other than an
increase in cloud cover... Dry weather will continue for the rest
of the forecast area. Only other change was to nudge high
temperatures generally up a degree or so across the board.

Zone and grid updates out.

Short term tonight through Tuesday night
Issued at 210 am edt Sun aug 25 2019
active weather is set to return to central indiana during this
period. The GFS and NAM both suggest the influence of the upper
low over the plains states tonight as initial short waves push
across indiana tonight ahead of a broad trough aloft. GFS and nam
show the arrival of deep saturation across the area by 12z Monday.

The 305k GFS isentropic surface shows broad up-glide... But
specific humidities are quite high... Over 10 g kg. Forecast
sounding pwats surge to over 2 inches. Thus will trend toward pops
at or above the nbm on late tonight and on Monday as these
features come into play. Given the expected rain... Will trend lows
higher than the nbm given the rain and Monday's highs lower.

On Monday night and Tuesday another quick moving pair of short
waves pass through indiana within the broad cyclonic circulation
over canada. This time forecast soundings reveal a much shallower
layer of moisture available. Within the lower levels show a
sharper cold front passing overnight and early Tuesday. Thus this
looks more like a system with very light precip amounts. Due to
he uncertainty... Will stick close to the nbm pops here.

Stronger subsidence and drying within the column builds across the
area Tuesday afternoon and Tuesday night. Surface flow remains
nwerly with cold air advection and subsidence in play. Thus will
trend toward a dry forecast on Tuesday afternoon and night.

Long term Wednesday through Saturday
Issued at 236 am edt Sun aug 25 2019
models and ensembles in agreement that surface high pressure will
build in from the plains and result in dry weather through at least
Thursday night. Then, models suggest a cold front will move through
the area around Friday. Models also have some QPF by Friday.

However, blend keeps it mostly dry. Prefer to keep it dry for now
but knowing that at pops and QPF may need to be added in future
forecasts.

Slightly below normal blend temperatures look reasonable with
afternoon highs in the upper 70s to the lower 80s.

Aviation discussion for the 251500z TAF update
Issued at 1029 am edt Sun aug 25 2019
tafs in good shape currently with no changes for the mid morning
update. 12z discussion follows.

Good confidence inVFR conditions through at least 08z Monday. Then,
showers will spread over the terminals with the possibility of MVFR
or worse conditions.

Winds will be east and southeast 6 to 9 knots.

Ind watches warnings advisories None.
