Area Forecast Discussion
National Weather Service Northern Indiana
243 PM EDT Thu May 24 2018

.SYNOPSIS...
Issued at 239 PM EDT Thu May 24 2018

High pressure will continue to provide fair weather conditions
into tonight and Friday. Lows tonight will range between the mid
50s and low 60s, with highs on Friday into mid to upper 80s.
Temperatures and humidity will be on the increase in time for the
holiday weekend. Highs each day will range between the mid 80s and
low 90s. There is a low chance for showers and thunderstorms
Friday night into Saturday. Mainly dry conditions are expected
otherwise into early next week.

&&

.SHORT TERM...(This Evening through Friday)
Issued at 239 PM EDT Thu May 24 2018

Stable/dry airmass on the western fringe of a low level ridge axis
will ensure more fair wx into tonight and Friday. Temperatures will
continue to trend warmer as sfc winds veer more southwesterly on
Friday.

&&

.LONG TERM...(Friday Night through Thursday)
Issued at 239 PM EDT Thu May 24 2018

The holiday weekend will feature unseasonably humid/hot temps and
low chances for storms mainly Saturday...

A mid level trough and associated 30-40 meter height falls at 500 mb
will work east through the region Friday night into Saturday. This
feature will fold higher theta-e air and a subtle sfc trough in
bringing clouds and chances for showers/storms back into the
forecast during this time. Overall weak deep layer forcing/flow
continues to support low PoPs (generally 20-30%) during this
time...best chances Saturday afternoon along/east of I-69 tied to
diurnal/heating cycle. Sunday and Monday should feature dry/hot
conditions as upper ridging becomes re-established over the Great
Lakes region. Northern stream westerlies will then finally ingest
deeper moisture (from a Deep South upper low) north by mid-week
bringing renewed shower/storm chances Wed-Thu.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 126 PM EDT Thu May 24 2018

High pressure continues to move east changing the wind direction
to more southwesterly and keeping dry VFR conditions around. High
clouds look to enter towards the end of the forecast period. Winds
will continue to remain light during the period with the low level
jet situated north of the area.
