Area Forecast Discussion
National Weather Service Northern Indiana
416 AM EDT FRI AUG 26 2016

Issued at 1249 AM EDT Fri Aug 26 2016

Dry and less humid conditions can be expected today as high
pressure shifts into the Great Lakes. Highs this afternoon are
forecast to reach the low to mid 80s, with lows Friday night into
the 60s. Chances for showers and thunderstorms will then return
Saturday into Sunday as a frontal boundary lifts into the region.
Humidity levels will also be on the increase this weekend with
highs each day in the 80s.


.SHORT TERM...(Today and Sat night)
Issued at 344 AM EDT Fri Aug 26 2016

High pressure ridge building in from the nw behind wk cdfnt which
moved across the area yday aftn/eve. Still moist low levels
combined with light winds and a period of clear skies has
resulted in patchy fog development across our cwa. High
cloudiness streaming n-ne around strong upr high over the mid
Atlantic states and ahead of a trof digging into the nrn Plains
expected to prevent fog from becoming widespread dense early this
morning and result in just filtered sunshine today. Wk waa will
develop tonight as this ridge moves off to se Canada.
Showers/Tstms expected to spread ne from the srn Plains into the
waa regime to our west, aided by wk disturbances in the rather
strong swly flow aloft. This sct convection should spread across
our area late tonight through Sat as the nrn Plains upr trof moves
east to the upr grtlks.


.LONG TERM...(Sunday through Thursday)
Issued at 344 AM EDT Fri Aug 26 2016

Wk backdoor sfc cdfnt associated with upr trof movg east into
se Canada Sunday expected to move into our area and probably
linger through Monday, psbly triggering isolated mainly aftn/eve
thunderstorms in this timeframe. Mid Atlantic states upr ridge
expected to shift west to the plains by Tue as a rather strong upr
level trof digs into the west coast. Shrtwv movg over the top of
the dvlpg plains ridge expected to cause a wk cdfnt to move
through our area Tue psbly providing sufficient support for a few
tstms. High pressure should build in behind this front providing
fair wx and slightly cooler temps Wed/Thu.


.AVIATION...(For the 06Z TAFS through 06Z Friday Night)
Issued at 1249 AM EDT Fri Aug 26 2016

Drier air will filter into northern Indiana today as a weak
frontal boundary drops off to the south and sfc high pressure
shifts into the Great Lakes region. Could see some BR formation
early this morning, best chances at KFWA toward daybreak. Light
winds and VFR otherwise.
