AREA FORECAST DISCUSSION
National Weather Service Northern Indiana
700 PM EDT TUE JUL 26 2016

.SYNOPSIS...
Issued at 700 PM EDT Tue Jul 26 2016

Warm but less humid conditions will continue tonight and Wednesday
with lows dropping into the mid 60s and highs reaching 85 to 90. The
humidity will then gradually build with the next chance for showers
and storms coming Thursday afternoon and persisting into Saturday as
an upper level trough deepens across the middle part of the nation.

&&

.SHORT TERM...(This Evening through Wednesday)
Issued at 231 PM EDT Tue Jul 26 2016

Tranquil wx conts this pd under the influence of low amplitude
ridging sfc and aloft and in concert w/swd displacement of active
frontal zone through srn IL/IN.

&&

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 231 PM EDT Tue Jul 26 2016

Generally zonal flw aloft underneath east Canada troughing will
break twd more upr ridging cntrd acrs the cntrl plains by erly nxt
week. Given a lack of a sig synoptic scale sw trough and inherent
weak flw aloft... xpc old synoptic fntl zone will remain
entrenched down alg the OH river this pd. Thus generally minimal
precip chcs seen as sig mstr rich theta-e ridge holds south of the
Great Lakes.

Some exception to this rule may dvlp twd lt dy7/dy8 in tandem w/bldg
upr ridge out west and degree of hgt amplification aloft that ensues.
This would fvr a btr downstream waa current that would dvlp newd
into the lakes and suggestive of a potential more active nw flw
pattn on mid nxt week and beyond hwvr ltl coherent signal as yet
present in med range solutions to hedge more strongly yet. Otrws
seasonable temps xpcd through the pd.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday Evening)
Issued at 700 PM EDT Tue Jul 26 2016

VFR conditions will persist through the period as weak surface
ridging continues to prevail. Patchy ground fog is possible by the
early morning hours but forecast soundings continue to indicate dry
low levels...and even GSH only went down to 6SM BR for one hour
early this morning so will refrain from any mention in TAFs once
again this cycle.
