Area Forecast Discussion
National Weather Service Northern Indiana
1233 AM EDT Thu May 24 2018

.SYNOPSIS...
Issued at 1227 AM EDT Thu May 24 2018

High pressure over the area will keep conditions dry and skies
mostly clear through Friday. Expect light winds and lows in the
50s tonight. Temperatures will be unseasonably warm through the
holiday weekend, with highs in the 80s to around 90. There is a
small chance for late afternoon showers and storms Saturday
through Memorial Day.

&&

.SHORT TERM...(This Evening through Thursday)
Issued at 249 PM EDT Wed May 23 2018

Sfc high pressure will remain entrenched across the region into
tonight and Thursday as upstream upper ridge axis builds east over
the Great Lakes. The result will be more fair weather and gradual
warming. Good radiational cooling could provide some patchy ground
fog early Thursday morning, though minimal impact currently
anticipated given ongoing mixing/drying of the near surface layer.

&&

.LONG TERM...(Thursday Night through Wednesday)
Issued at 249 PM EDT Wed May 23 2018

Stable/warm profile with low level winds becoming more
southwesterly will promote another bump in highs and continued
dry/mostly sunny conditions into Friday. The Great Lakes upper
ridge does briefly break down Friday night into Saturday as weak
troughing/height falls overspread. This will coincide with
increasing moisture/instability to support shower/storm chances
into mainly nw IN/sw MI Friday night and the entire forecast area
on Saturday. The bulk of the upper level energy does look to pass
well north through the Northern Great Lakes, which should limit
coverage/point chances this far south. Held with a low 20-30 PoP
as a result during these periods...highest Saturday afternoon as
instability peaks with weak sfc trough dropping through.
Mild/partly cloudy otherwise on Saturday with highs likely
reaching the mid- upper 80s.

Unseasonably warm temperatures will remain the story Sunday
through Tuesday as aforementioned troughing lifts out of the
Great Lakes and tropical circulation stalls across the Deep
South/TN Valley. Mainly dry conditions will result, though
cannot rule out an afternoon/evening shower each afternoon near
any lake/outflow/differential heating boundaries (5-20% chc).
