Area Forecast Discussion
National Weather Service Northern Indiana
1127 PM EDT Sat Mar 24 2018

Issued at 1122 PM EDT Sat Mar 24 2018

Dry and warmer conditions will arrive for the region into the
first part of the work week with highs in the 40s Sunday and
Monday warming into the 50s for Tuesday and Wednesday. Rain will
arrive Monday night and linger into Tuesday.


.SHORT TERM...(This Evening through Monday)
Issued at 306 PM EDT Sat Mar 24 2018

Despite some impressive radar returns at times, especially this
morning, only minor accumulations and no impacts have been
reported in White county as wall of dry air was fighting hard to
keep the snow away (Hi res models showing nearly 200 mb deep layer
of dry air). Temp/dewpoint depression of 15 degrees or more in
the area and even back into Jasper county show the struggle going
on despite strong lift aloft. With no impacts and the event
winding down over the next several hours opted to drop the
advisory (in coordination with LOT and IND). Can`t rule out a few
heavier snow showers in far SW areas prior to 00Z as leading edge
of snow showers could clip the area. Any impacts would be minimal
and brief given temperatures still above freezing.

As forcing departs this evening, brief quiet period will settle in
as upper level ridging moves in with highs reach well through the
40s and even 50s by Monday.


.LONG TERM...(Monday Night through Saturday)
Issued at 306 PM EDT Sat Mar 24 2018

Long term will turn active and eventually colder as general
longwave trough becomes entrenched across the central US. Warmest
period still looks to be Monday night into Tuesday at the same
time deep moisture will arrive with the first wave of energy to
bring rain and possibly a few storms to the area. Highs Tuesday
will climb well into the 50s and maybe near 60 in a few spots. in
terms of precipitation, most locations look to get between a half
inch to an inch of rain, with higher amounts possible. Given it
has been over a month since all the heavy rain/major flooding
issues, only limited rainfall since that time and expected QPF,
think flooding concerns will be minimal at this point but still
warrant watching.

First trough will send temps a touch cooler into Thursday with
highs in the 50s still. Stronger wave will arrive into Thursday to
bring another chance of light precip. Still indications of even
colder air up in Canada ready to drop into the region outside the


.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 1120 PM EDT Sat Mar 24 2018

A large surface anticyclone over east Canada with a ridge
extending into the Great Lakes region will help keep a cool and
dry northeast to east flow over the area through the TAF period.
Precipitable water values will remain under 0.20" with VFR
conditions continuing as the lower atmosphere remains very dry.


LM...Small Craft Advisory until noon EDT Sunday for LMZ043-046.
