Area Forecast Discussion
National Weather Service Indianapolis IN
700 PM EDT Thu May 30 2019

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

&&

.SYNOPSIS...
Issued at 241 PM EDT Thu May 30 2019

A frontal system is expected to drift through the area tonight into
early Friday. Another frontal system may affect the area around
Saturday. In the wake of this front, high pressure will build into
the area by early next week.

&&

.NEAR TERM /Rest of This Afternoon and Tonight/...
Issued at 241 PM EDT Thu May 30 2019

Scattered convection beginning to develop over northern Indiana, in
an unstable air mass along and near a weak frontal zone. Convection
should gradually shift south during the evening, as the front
drifts south. Pattern really doesn't favor nocturnal convection tonight,
as the 850mb flow is quite weak. As a result, any convection that
does form may tend to diminish later tonight. However, the presence
of a shearing upper trough will probably keep some potential for
shower activity around most of the night. Will go with chance PoPs
tonight, with the highest PoPs over the north and central zones during
the evening hours.

Could be some fog development during the pre dawn hours of Friday,
given the weakly convergent low level flow near the front. Fog
threat may be locally higher in areas that end up getting rain this
evening.

Low level thicknesses suggest the GFS MOS lows tonight look good, so
little if any adjustments planned.

&&

.SHORT TERM /Friday through Sunday/...
Issued at 241 PM EDT Thu May 30 2019

Model data suggest upper trough may still be lingering over the
southeast zones Friday morning. As a result, will keep some chance
PoPs for showers over these areas through the morning hours.

Otherwise, northwesterly flow expected to develop during this
period, as long wave troughing develops over the eastern parts of
the country. This should help to bring drier and more stable air
into the area by Friday afternoon and night. Will go dry at these
times.

Model data suggest a short wave trough, and associated frontal
system, will drop southeast through the area Saturday afternoon and
night. Model data generate quite a bit of lift with this feature,
along with moderately steep lapse rates. Will go with chance PoPs
for showers and thunderstorms for mainly Saturday afternoon and
night.

Dry weather expected to return by Sunday, as surface high pressure
builds into the area from the northwest.

Progged low level thicknesses suggest the GFS MOS temperature guidance
during this period looks good for the most part.

&&

.LONG TERM /Sunday night through Thursday/...

Issued at 248 PM EDT Thu May 30 2019

Dry weather is expected at the start of the long term period as
high pressure sits over central Indiana. Chances for rain increase
later in the week with the first chances for rain and a few
thunderstorms on Wednesday as a weak upper level disturbance
moves through. Additional rain and a few thunderstorms are
possible again on Thursday with lower confidence on the Thursday
chances. Ensembles have a significant spread on timing for
Thursday, so confidence is low for the rain chances. Severe
weather is possible Wednesday with models indicating plenty of
CAPE and shear expected.

Temperatures will begin the period below average and end slightly
above normal.

&&

.AVIATION /Discussion for the 00Z TAF Issuance/...
Issued at 700 PM EDT Thu May 30 2019

Good confidence in mostly VFR conditions away from thunderstorms
through the TAF period. Convection could hang around til 06z or so
per the High Resolution Rapid Refresh reflectivity progs. After
that, high pressure will build in.

Winds will be west and northwest or variable 7 knots or less away
from thunderstorms.

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