Area Forecast Discussion
National Weather Service Northern Indiana
645 AM EDT Fri Mar 16 2018

Issued at 642 AM EDT Fri Mar 16 2018

Dry but cool weather is expected today, with highs around 40
degrees. A wintry mix will move into the area late tonight into
Saturday morning. Light snow and ice accumulations are possible,
mainly south of US 30. Clouds and precipitation will diminish
gradually on Saturday as highs warm into the 40s. Pleasant weather
is expected on Sunday, with temperatures rising to near 50


.SHORT TERM...(Today through Saturday)
Issued at 422 AM EDT Fri Mar 16 2018

The surface low associated with the next upper level system had
ejected out into the High Plains where the surface pressure was
already below 990 mb. This system will continue to track east
today under the upper ridge and bring a wintry mix tonight into
early Saturday. The system will race through and expected to bring
mainly freezing rain south of highway 30. After coordinating with
neighboring offices, have issued a winter weather advisory for
mainly freezing rain south of US 30. It appears pavement
temperatures may be just below freezing causing early morning
travel issues.


.LONG TERM...(Saturday night through Thursday)
Issued at 422 AM EDT Fri Mar 16 2018

Skies should clear by Saturday evening with briefly warmer
weather between systems Sunday with highs near 50. Another system
should follow a similar track of the first system and bring
another wintry mix early next week. It looks like this next system
will have more snow than ice. Confidence with any solution still
remains very low with this second system.

Issued at 642 AM EDT Fri Mar 16 2018

the southwest late tonight into early Saturday morning, expect MVFR

towards the 10-12z time frame. KSBN will remain VFR. Winds will
become more easterly through the period.
