Area Forecast Discussion
National Weather Service Northern Indiana
732 PM EDT Thu Mar 15 2018

Issued at 210 PM EDT Thu Mar 15 2018

Dry but cool weather can be expected through Friday with highs
around 40. A wintry mix is expected Friday night with some light
snow and ice accumulations likely by daybreak Saturday. Clouds
will decrease Saturday with highs from 40 to 45. Sunday will be
mostly sunny and warmer with highs near 50.


.SHORT TERM...(This Evening through Friday)
Issued at 318 PM EDT Thu Mar 15 2018

Quiet weather continues through most of the short term period with
mostly clear skies tonight and mostly sunny skies tomorrow. Temps
remain on the cooler side with afternoon highs in the upper 30s
to lower 40s and overnight lows in the 20s. Next system moves in
at the very end of the short term period overnight Friday into
early morning Saturday bringing a wintry mix of precipitation.


.LONG TERM...(Friday Night through Thursday)
Issued at 318 PM EDT Thu Mar 15 2018

Quick moving system moves into the area overnight Friday into early
Saturday. Biggest concern is in precip type on the northern edge of
the precip shield. Still some uncertainty in how far north the warm
air makes it. Currently thinking areas along and south of US 30 will
see a brief period of freezing rain due to warm nose aloft. Based on
system track, Michigan zones may stay mainly dry throughout the
day. Heaviest precip will stay along and south of US 24 with up to
around 0.1 inch freezing rain. Expect less accum on roads due to
warm pavement temps. Temps warm during the day transitioning
precip to all rain by Sat afternoon and melting any ice
accumulations from the early morning.

Small ridge develops overhead late Sat into Sun bringing near to
above normal temps into the area with afternoon highs in the upper
40s to lower 50s Sunday and Monday. Series of shortwaves move
through starting Tuesday bringing cooler temps and additional
chances of precip through the middle of next week. Possible wintry
mix associated with these shortwaves but still some disagreement
in model guidance with how much cold air is in place.


.AVIATION...(For the 00Z TAFS through 00Z Friday Evening)
Issued at 729 PM EDT Thu Mar 15 2018

VFR conditions continue through the forecast period with
subsidence prevalent overnight. The only other mentionable portion
of the forecast will be that the winds become more easterly by
end of day Friday after starting the period more northerly.


LM...Small Craft Advisory until 4 AM EDT Friday for LMZ043-046.
