Area Forecast Discussion
National Weather Service Northern Indiana
420 AM EDT Sun Mar 18 2018

Issued at 324 AM EDT Sun Mar 18 2018

High pressure will bring a dry and pleasant day to the region.
Light winds and clear skies will continue through Monday, with
high temperatures in the 40s and low to mid 50s. There is a slight
chance of snow south of US 24 Monday night, but little to no
accumulation is expected. Lows tonight and Monday night will be
in the 20s and 30s.


.SHORT TERM...(Today and Tonight)
Issued at 325 AM EDT Sun Mar 18 2018

A weak upper level ridge will be over the area through tonight as
a surface high pressure area drifts across the region. Patchy
ground fog is likely early this morning south of Ft Wayne. Very
dry air in the low levels will allow the fog to mix out rapidly
after daybreak. Given full sun today with low level thermal fields
near the climatological norm, highs today will rise a little
above normal into the 50s. Winds will remain light given a weak
pressure gradient over the area.


.LONG TERM...(Monday through Saturday)
Issued at 325 AM EDT Sun Mar 18 2018

Some energy in the form of an upper low will eject east early this
week out of the large western North America low. This system will
move east and track farther south then earlier expected, keeping
most of the area dry. There is a chance for light rain and snow
south of Fort Wayne Monday night through Tuesday night; however,
few if any impacts are expected. Much below normal temperatures
with mainly dry weather is expected Tuesday through Thursday with
highs mainly around 40. After Thursday, a more unsettled pattern
will follow into the weekend. Numerous scenarios are possible as
more energy arrives over the area eventually bringing rain or
snow. Precipitation is likely at some point from late Friday over
the weekend, but timing is uncertain.


.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 134 AM EDT Sun Mar 18 2018

VFR conditions are expected at both terminals tonight. High pressure
overhead will lead to light winds and clear skies. T/Td spread
should preclude any fog/BR development overnight.
