Area Forecast Discussion
National Weather Service Northern Indiana
334 AM EDT Tue May 22 2018

.SYNOPSIS...
Issued at 123 AM EDT Tue May 22 2018

Lingering showers and possibly a rumble of thunder will end later
today. Dry and much warmer weather is ahead with highs mostly in
the 80s from Wednesday through the end of the week.

&&

.SHORT TERM...(Today and Tonight)
Issued at 307 AM EDT Tue May 22 2018

Areas of dense fog have developed across the western zones and
over the lake this morning. Expect this fog to persist into the
late morning hours. Scattered showers and possibly an isolated
thunderstorm are possible into the afternoon hours primarily
across the far southeastern zones. PWAT values remain
climatologically high for late MAy so any storms that develops
would be capable of producing locally heavy rainfall. A cold front
will push through the evening to bring a close to our rain
chances through the overnight hours. High temperatures are
expected to range from 60s across the north and west with 70s
across the south and east. Overnight lows will drop into the 50s
for much of the area.

&&

.LONG TERM...(Wednesday through Monday)
Issued at 307 AM EDT Tue May 22 2018

Upper level ridging sets up over the region by Wednesday and will
persist through the end of the work week. This will result in dry
and warmer weather with high temperatures each day being about 5
degrees above season averages for late May. As the Memorial Day
weekend starts a pattern change is on the horizon. Height falls
over the area as a pair of upper lows emanate out of Manitoba
will bring off and on rain chances back to the area into the early
parts of next week.

&&

.AVIATION...(For the 06Z TAFS through 06Z Tuesday Night)
Issued at 119 AM EDT Tue May 22 2018

A weak area of low pressure will move across northern Indiana
today. This system will help keep low clouds over the SBN terminal
for much of the TAF period. FWA is expected to drop down to IFR
for a few to several hours this morning before becoming VFR by
noon. Winds will eventually become northwest as the low moves out
of the area with some brief clearing possible at SBN after 00z.


&&
