Special Weather Statement, NWS Indianapolis, IN

Area Forecast Discussion
National Weather Service Indianapolis IN
639 PM EDT Tue Jul 2 2019

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

&&

.SYNOPSIS...
Issued at 330 PM EDT Tue Jul 2 2019

The heat and humidity will continue through at least Friday as high
pressure remains in place. That said, numerous weak upper waves will
pass over the area through Friday. Any of these could interact with
the heat and instability and spark thunderstorm development.

A cold front will drop slowly southeast across the area this
weekend. This will result in more thunderstorms but more seasonable
temperatures in its wake.

&&

.NEAR TERM...(Remainder of Afternoon and Tonight)
Issued at 330 PM EDT Tue Jul 2 2019

The main concerns for the near term will be the heat and
thunderstorms.

Persistent surface high pressure over the southeastern states and
upper Ohio Valley along with a weak upper ridge over the Ohio Valley
and Great Lakes have allowed for a persistent very warm and humid
airmass over central Indiana. Even with very little synoptic
forcing, a few thunderstorms have popped over the forecast area and
nearby, associated with weak upper impulses and small scale
boundaries. Should continue to see this through at least the evening.

Updated the Special Weather Statement to continue to mention near
100 degree Heat Index potential through early evening as
temperatures have reached 90 degrees and dew point temperatures were
around 70 degrees at some locales.

Blend lows in the lower 70s look reasonable based on afternoon dew
points and limited sky cover away from thunderstorms.

&&

.SHORT TERM...(Wednesday through Friday)
Issued at 330 PM EDT Tue Jul 2 2019

Thunderstorm coverage and the heat will be the main concern during
the short term.

Wednesday should be a lot like today as models were indicating the
potential for upper impulses and surface boundaries to interact with
strong instability and result in scattered thunderstorms, with the
best chances during the afternoon and early evening. A few strong or
even severe storms are possible with wet microbursts the main
concern per the Storm Prediction Center Day2 Outlook.

Higher chances /likely/ for thunderstorms during the afternoon and
early evening of the Fourth of July and also on Friday as an upper
trough will move in and a cold front will approach from the
northwest. Moderate to good confidence in less coverage after dark
on the Fourth.

With a few more clouds around, temperatures may not be quiet as hot
per the blend.

&&

.LONG TERM /Friday Night through Tuesday/...

Issued at 218 PM EDT Tue Jul 2 2019

General weather pattern begins a slow retrogression of the
southern States ridge into the southern Plains allowing a west-
northwest flow around that ridge over central IN. Several weak
short wave troughs will move through the area during the period
for occasional showers and thunderstorms.

Looks like the first chance for showers and thunderstorms comes
ahead of a cold front that will pass southeastward through the
region late Friday night into Saturday morning. High pressure
falls into the area for Sunday. Looks like the next chance for
showers and thunderstorms return towards Tuesday as
moisture/humidity returns on the backside of high pressure as it
moves off to the east.

Slight welcome of relief from the heat coming during this period
as high temperatures will be slightly below average in the mid 80s
and lows get into the mid 60s this weekend.

&&

.AVIATION /Discussion for 030000Z TAF Issuance/...
Issued at 639 PM EDT Tue Jul 2 2019

Outside of convection impacting any of the terminals...VFR
conditions expected throughout the forecast period.

Scattered diurnal convection continues early this evening and
should diminish near or just after sunset as peak heating is
lost...leaving partly cloudy skies overnight. Larger convective
cluster over the western Great Lakes may eventually drift into
northern Indiana later tonight but other than increasing high
level clouds...do not anticipate any impacts from those storms at
the terminals overnight.

Expect more of the same Wednesday as scattered convection is
likely to generate by early to mid afternoon within the moist and
unstable airmass. Will introduce VCTS mention at all terminals
after 18Z Wednesday. Generally light SW flow is expected through
the forecast period.
