Area Forecast Discussion
National Weather Service Northern Indiana
733 AM EDT Mon Apr 23 2018

.SYNOPSIS...
Issued at 341 AM EDT Mon Apr 23 2018

A weak and slow moving low pressure area will move north of the
Ohio River and bring a chance for light rain and sprinkles to the
forecast area from this afternoon through Tuesday night. Mainly
dry weather is forecast for Wednesday and Thursday. Highs today
will be in the 60s to around 70. Lows tonight should be in the
upper 40s. Highs Tuesday through Thursday will be in the mid 50s
to lower 60s all 3 days.

.SHORT TERM...(Today and Tonight)
Issued at 325 AM EDT Mon Apr 23 2018

An upper low was near Memphis early this morning. This system was
drifting east, but should curve north as an interaction with an
upstream system takes place. Some bands of light rain or light
showers are likely to spread north of the Ohio River with a chance
for some rain reaching areas east and south of Warsaw by this
evening. More of a widespread light rain is likely tonight over
much of the area into early Tuesday. Precipitation amounts will
be light as the bulk of the system passes to the southeast. Highs
today will approach 70 near the Michigan border; however, cooler
highs should prevail farther south where clouds and possible rain
hold temps down.

&&

.LONG TERM...(Tuesday through Sunday)
Issued at 325 AM EDT Mon Apr 23 2018

Lingering areas of light rain or showers should end Wednesday
morning as the upper low moves east. Temperatures should be a
little below normal from Tuesday thru Thursday with highs in the
middle 50s to lower 60 each day. One last system may bring some
light rain Friday. Limited cold air behind this system may allow
lows to drop to 34-37 Friday night. Otherwise, much warmer weather
is ahead just past next weekend as an upper level ridge builds
east.

.AVIATION...(For the 12Z TAFS through 12Z Tuesday Morning)
Issued at 731 AM EDT Mon Apr 23 2018

VFR flight conditions at least until late in the forecast period.
Mid level circulation with associated deep layer moisture near the
Missouri bootheel to gradually move east-northeast into southern
Kentucky by the end of the forecast period. Concern is that with
nocturnal cooling and degree of low level moisture influx will
work in concert to bring ceilings crashing down. For outlook
purposes change group late in latest forecast, lowering to IFR at
KFWA in closer proximity to moisture feed and a bit more
optimistic farther northwest/KSBN.
