Area Forecast Discussion
National Weather Service Northern Indiana
228 PM EDT MON JUL 25 2016

Issued at 227 PM EDT Mon Jul 25 2016

An isolated shower or storm could develop along an exiting cold
front along and south of a Marion Indiana to Lima Ohio line. Dry
and less humid otherwise tonight through the middle of next 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 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 132 PM EDT Mon Jul 25 2016

The cdfnt has moved through northern IN with winds wnw at both
sites. High pressure builds into the area tonight with light and
variable winds and clear skies. Do not think there will be
sufficient bndry layer moisture to be concerned about fog so did
not mention it in the fcst.


.IWX Watches/Warnings/Advisories...
MI...Beach Hazards Statement until 3 PM EDT this afternoon for MIZ077.
