Area Forecast Discussion
National Weather Service Northern Indiana
332 AM EDT Thu Aug 3 2017

.SYNOPSIS...
Issued at 330 AM EDT Thu Aug 3 2017

Isolated to scattered thunderstorms are possible late this afternoon
mainly west of US 31. Otherwise a sharp cold front will drive east
across the area late tonight into early Friday morning with
scattered thunderstorms expected. Much cooler weather will arrive
Friday and persist into Saturday before temperatures moderate warmer
through next week.

&&

.SHORT TERM...(Today and tonight)
Issued at 330 AM EDT Thu Aug 3 2017

Eliminated most near term pops on account of substantial theta-e
minimum seen in 00Z raob at KILX which will advance newd across the
cwa through early aftn. Much better low level theta-e ridging will
then push into wrn areas ewd of cyclone wrapping up across the upper
midwest and in concert with upticking low level jet after 21Z. Some
evidence of a prefrontal trough feature at that time coming out of
ne IL as indicated in most CAMS guidance and will confine higher
chance pops far west late this aftn.

Otherwise ewd progression of cold frontal zone commences tonight
albeit slower versus prior model based guidance and expect much of
this will wash out/decay with ewd extent across the cwa especially
late. Will modify according to preferred blend and in light of 00Z
based mos trends.

&&

.LONG TERM...(Friday through Wednesday)
Issued at 330 AM EDT Thu Aug 3 2017

Strong post frontal cold advection will overspread the area Fri
morning. Steepening sfc based lapse rates within residual low level
moisture plume should bubble by late morning into mid aftn with
isolated to scattered showers pending arrival/extent of entraining
dry air.

Following sfc ridging will then expand through the OH valley Sat
before breaking down in advance of next nrn plains sw disturbance
late Sun which is forecast to shear out overhead late Mon. Return
flow ahead of this system warrants holding onto low chc pops Sun
aftn into Mon. Renewed sfc ridging and dry weather expected to
prevail then through the rest of the period.

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday Night)
Issued at 118 AM EDT Thu Aug 3 2017

Calm/light winds, mainly clear skies, and small dewpoint
depressions may result in some patchy BR/FG formation that may
impact the terminals around daybreak. VFR/dry otherwise through
the early afternoon.

Widely scattered showers/storms will likely develop into mainly
northwest IN later this afternoon into this evening as
flow/instability increases near a pre-frontal trough. Held with a
VCTS mention after 21z at KSBN for now, with point chances too low
for a mention at KFWA. The main/seasonably strong cold front comes
through the region just beyond this TAF cycle (06-12z 8/4).
