Area Forecast Discussion
National Weather Service Northern Indiana
320 AM EDT SUN AUG 28 2016

Issued at 338 PM EDT Sat Aug 27 2016

A few showers and thunderstorms are possible across the area today
as a weak cold front moves through. High pressure will build into
the Great Lakes behind the front providing dry weather tonight
through Tuesday. Highs today will be in the middle to upper 80s,
except a little cooler than that near Lake Michigan. Lows tonight
will be in the lower to middle 60s.


.SHORT TERM...(Today and Tonight)
Issued at 307 AM EDT Sun Aug 28 2016

Wk cdfnt over mi/nrn il managing to spark a few showers/tstms just
nw of our cwa attm. This diffuse front should move slowly se
across our cwa today and is expected to provide sufficient low
level convergence combined with right entrance region upr jet
dynamics for isolated to sct showers/tstms over our nw this
morning and se this aftn/eve. Strengthening sfc high behind the
front will move east across lwr mi tonight, advecting drier air
via ne winds into our area allowing for dry conditions overnight which
should persist through Tuesday as the ridge drops slowly se.

Not much change in temps today with dvlpg wk low level
caa counteracted by building heights associated with retrograding
mid atlantic coast ridge. Drier air advecting into the area
tonight should allow for a little cooler temps with lows near
normal in the l-m60s.


.LONG TERM...(Monday through Saturday)
Issued at 307 AM EDT Sun Aug 28 2016

Next cdfnt should be a little more impactful from a
temperature standpoint as upr ridge amplifies over the high
plains allowing nw flow aloft to develop over the grtlks and ne
conus. This front expected to move through the area tue ngt
accompanied by just wk convergence/instability, but again some
right entrance region upr jet dynamics, warranting chc pops in the
vcnty of the front. A large high pressure system will drop se
across the grtlks behind this front thu-fri and to the mid-
atlantic coast sat with a trailing ridge back into the midwest
which should result in contd fair wx across our area in this
timeframe with temps a bit blo normal, but moderating into the


.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 1249 AM EDT Sun Aug 28 2016

Moist low levels and light winds should allow for patchy VIS
restrictions between 08-13z, though confidence has diminished in
more significant IFR/LIFR restrictions occurring given persistent
bkn mid-high level cloud deck and latest MOS guidance. Have
trended more optimistic with VIS/Stratus restrictions during the
early morning as a result. the only other concern will be low
chances for an isolated storm at KSBN this morning and KFWA this
afternoon as weak low level convergence axis settles southeast
into northern Indiana. Point chances continue to look too low for
a VCTS mention attm. VFR/dry/light winds otherwise today into this
