Area Forecast Discussion
National Weather Service Northern Indiana
1125 PM EDT WED AUG 24 2016

Issued at 350 PM EDT Wed Aug 24 2016

Showers and thunderstorms are possible through Thursday ahead of
a slow moving cold front as weak upper level systems move across
the area. Tornadoes are possible over the southern portion of the
area into early this evening, south of a line from Huntington to
Decatur. In addition to these storms, there is also the chance for
severe storms over part of the area Thursday. Locally heavy rain
will also be a concern. Highs will be in the low to mid 80s each


Issued at 1115 PM EDT Wed Aug 24 2016

Severe wx threat appears to finally have diminished. MCV pushing
across nwrn OH with line of showers/storms arcing s-sw ahead of
it have moved out of our cwa with stable air in its wake. Clearing
skies and fairly light winds combined with moist low levels should
allow patchy fog to develop overnight. Storms along cdfnt over nrn
MO will move east overnight but likely not reach our cwa before
after daybreak Thu and prbly wkng by that time.


.SHORT TERM...(This Evening through Thursday)
Issued at 351 PM EDT Wed Aug 24 2016

Factors have become favorable for tornado development over the
southern portion of the area; south of the area of the ongoing
showers and isolated storms. This includes the area south of a
line from Grissom to Plum Tree to Monroe. An upper level
disturbance along with a low level jet has aided in low level
shear with Helicity values of 350 with shear of 30 m/s. Daytime
destabilization of the airmass with LCL heights below 750 meters
have allowed storms to produce tornadoes in the Kokomo area. The
Storm Prediction Center has included part of our forecast area in
a tornado watch until 8 PM this evening. Otherwise, the tornado
threat should end by late evening, More storms are possible
tonight, with another good chance for storms Thursday afternoon
with daytime heating. Localized flooding is possible with any
training storms, especially over areas that received extremely
heavy rainfall last week.


.LONG TERM...(Thursday Night through Wednesday)
Issued at 351 PM EDT Wed Aug 24 2016

There should be a break from the storms from Friday through Saturday
before the moist air returns to the area early next week. Storms are
possible again starting Saturday night through the middle of next
week. High temperatures should be in the low to mid 80s each day.


.AVIATION...(For the 00Z TAFS through 00Z Thursday Evening)
Issued at 822 PM EDT Wed Aug 24 2016

Storms associated with mcv movg across nrn IN have finally move
east of the terminals this eve. Expect much of the remainder of
the night will be precip free, but another area of ts ahead of
apchg cdfnt may move into nw IN toward daybreak and move across
the region during the day. Another concern is stratus/fog
potential overnight as low levels moist and winds fairly light.
For now, held off on fcstg ifr conditions and ts for Thu.
