Area Forecast Discussion
National Weather Service Northern Indiana
213 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...(Today and Tonight)
Issued at 403 AM EDT Thu Mar 15 2018

Fair but cool conditions will continue today and tonight as an
upper level ridge moves toward the area. However, temperatures
will still remain below normal with many areas having difficulty
breaking out of the upper 30s. Winds will veer to the northeast
late tonight ahead of the approaching upper level system.


.LONG TERM...(Friday through Wednesday)
Issued at 403 AM EDT Thu Mar 15 2018

A couple of upper level systems are expected to bring a mix of
precipitation starting Friday night into early next week. The
initial system will eject out from under the upstream upper ridge
and bring a wintry mix Friday night ending early Saturday. There
was still a large range of model solutions; however, the basic
trend was toward a more developed system. It looks like there will
be a substantial warm layer up to +6C that will extend north up
to near highway 30. Favor more freezing rain than sleet or snow
south of highway 30, bringing the potential for travel issues
early Saturday morning.

Skies should clear Saturday afternoon with briefly warmer weather
between systems Sunday with highs near 50s. Another system should
follow a similar track of the first system and bring another
wintry mix early next week. Snow accumulations are possible but
confidence with any solution remains very low with this second
