Area Forecast Discussion
National Weather Service Northern Indiana
1247 AM EDT TUE JUL 26 2016

Issued at 720 PM EDT Mon Jul 25 2016

Dry and less humid tonight through mid-week as high pressure builds
in. Lows tonight will drop into the low to mid 60s, with Tuesday`s
highs expected to reach the 80s. Similar temperatures...lows in the
60s and highs in the 80s...can be expected through the remainder of
the week. The next chance for showers and storms will come Thursday
into Friday as an upper level trough pushes into the Midwest and
Great Lakes.


.SHORT TERM...(This Evening through Wednesday)
Issued at 227 PM EDT Mon Jul 25 2016

Dry, subsident, air in wake of an upper level trough and leading
cold front will provide a mostly clear and slightly cooler/less
humid fcst through the middle of the week as high pressure builds
in. There may be just enough MLCAPE/CIN erosion and convergence
along surface cold front working through our far southeast zones
(Marion IN to Lima OH) to generate a few showers mid-late aftn. Fair
Wx and seasonable temps Tonight thru Wednesday otherwise as high
pressure dominates.


.LONG TERM...(Wednesday Night through Monday)
Issued at 227 PM EDT Mon Jul 25 2016

A transition to broad troughing/wnw flow in response to subtropical
ridge retrogression to the southwest US will set the stage for
slightly cooler temps and periodic rain/embedded thunder chances
as several smaller scale/Pacific Northwest shortwaves drop
through. Neither moisture return/convergence or large scale
forcing appears all that impressive but hard to rule out a few
periods of rain/thunder, best chances Friday and Saturday near
developing frontal boundary.


.AVIATION...(For the 06Z TAFS through 06Z Tuesday Night)
Issued at 1231 AM EDT Tue Jul 26 2016

High pressure will move slowly east across nrn Indiana this taf
period providing light winds and vfr conditions. Temps expected to
fall to at or just blo crossovers this morning but bufr fcst
soundings suggest low level moisture generally decreasing
vertically so sgfnt restrictions due to fog are not expected at
the terminals.
