Area Forecast Discussion
National Weather Service Northern Indiana
437 AM EDT Mon Mar 19 2018

Issued at 409 AM EDT Mon Mar 19 2018

High pressure will continue to bring dry and pleasant weather to the
region today. After early morning lows from around 25 to 30, highs
later today will range from the mid 40s northeast to the low 50s
southwest. Light snow is expected Tuesday into Wednesday from near
Lima to Portland where up to 2 inches is likely by early Wednesday.


.SHORT TERM...(Today through Wednesday)
Issued at 401 AM EDT Mon Mar 19 2018

An upper level system will move across the far southeast portion
of the area from Portland to Lima. Light snow accumulations of up
to 2 inches are possible from Tuesday into Wednesday as the
deformation zone associated with this system lingers over the
area. Temperatures will be much below normal Tuesday and Wednesday
with highs only around 40.


.LONG TERM...(Wednesday night through Sunday)
Issued at 401 AM EDT Mon Mar 19 2018

Waves of energy of pacific origin will be transported east late
this week and over the weekend across the upper level jet highway
and into the Midwest. These systems will bring plenty of potential
for rain and the possibility for accumulating snow. Still some
uncertainty about timing and location details, but an active and
wet pattern is looming from Friday into this coming weekend. A
rain and snow mix is likely from Friday night through Saturday as
thermal profiles hover close the the rain/snow threshold.
Otherwise, temperatures most days this week will be 5 to 10
degrees below normal with highs mainly in the 40s.


.AVIATION...(For the 06Z TAFS through 06Z Monday Night)
Issued at 126 AM EDT Mon Mar 19 2018

VFR conditions will continue through the TAF period. Easterly will
strengthen as the pressure gradient tightens between the
passing low pressure system to our south and the system to our far
north. Expect east-northeast winds to gust up into the 20-25 knot
range by late morning/early afternoon.


LM...Small Craft Advisory from 4 PM this afternoon to 4 AM EDT
     Wednesday for LMZ043-046.
