Area Forecast Discussion
National Weather Service Northern Indiana
740 PM EST Tue Mar 3 2020

.SYNOPSIS...
Issued at 740 PM EST Tue Mar 3 2020

Quiet weather is expected overnight but another system will pass 
through early Wednesday morning with a chance for light rain or 
snow, mainly north of Route 30. Minor accumulations on grassy 
surfaces are possible. Winds are expected to increase again 
Wednesday afternoon behind this system.

&&

.SHORT TERM...(This Evening through Wednesday)
Issued at 328 PM EST Tue Mar 3 2020

Southern edge of short wave racing across the forecast area at the
present time with uptick in shower activity. Dry low levels
keeping much if anything from reaching the ground despite nice
presentation on radar. A token 20 pops in in for the next couple 
of hours until this wave passes. Focus will then shift to upstream
clipper moving through Montana and Kansas that will move across
the area on Wednesday. Models varying on potential impacts with
this feature ranging from dry passage to up to an inch of snow.
Will be a quick window (3 to maybe 5 hours tops) of some precip
potential. Have ramped up pops to likely for a few hour period
across mainly west/north areas. A few tenths of an inch of wet
snow is possible but should only impact grassy areas as temps
hover near or just above freezing to start with slowly warming
temps through the morning. In the wake of the wave, gusty winds
will return similar to today. Upstream winds with this system are
much stronger (40 to 50 kt gusts). Don't expect anything in that
range here. 

&&

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 328 PM EST Tue Mar 3 2020

Stronger northern stream wave will drop in Thursday/Thurs ngt but
will be starved of moisture with little more than chc pops
warranted for now. Upper level height increases in store after
this system, with generally above normal temperatures Sat and
beyond. Next chance for rain will then arrive Sunday night into
Monday night with potentially widespread rain event arriving ahead
of the next stronger trough.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday Evening)
Issued at 618 PM EST Tue Mar 3 2020

Wind...showers...and diurnal cu will dissipate quickly with the 
loss of daytime heating and anticipate tranquil conditions 
overnight. Another potent but fast-moving shortwave will cross 
the area Wed morning. A narrow window of good forcing will support
brief impacts. Fuel alternate is likely at KSBN where stronger 
forcing and slightly cooler temps reside...resulting in lower 
ceilings and a greater chance for snow during heaviest precip 
rates. Impacts at KFWA are much less certain but a brief period of
high-end MVFR ceilings is likely. Both sites return to VFR 
quickly by the afternoon with a strong push of dry air advection.
