Special Weather Statement
Snow will end from north to south across the area early this
morning. The threat of accumulating snow will end north of I-80 by
7 AM and across northwest Indiana by 830 AM. Behind the snow,
lingering very fine light snow, snizzle, or very light freezing
drizzle may linger for a couple of hours. If precipitation were to
change to all freezing drizzle, the threat of icing on surfaces
appears low since it would likely be light and temperatures will
be warming to near freezing.

Until: Feb 06, 2026 14:00
Special Weather Statement
A fast moving weather system will produce a short 3 to 5 hour
period of freezing drizzle overnight into early Friday morning.
While significant ice amounts are not expected, a minor glaze of
ice will be possible on untreated surfaces such as sidewalks and
side streets. Accordingly, motorists and walkers should be
prepared for the possibility of some slick surfaces early Friday
morning.

Special Weather Statement
A fast moving weather system will produce a short 3 to 5 hour
period of accumulating snow overnight into early Friday morning.
While significant snowfall amounts are not expected, a burst of
snow, with rates up to 1 inch per hour, could result in a period
of slick travel due to snow covered roads early Friday morning.
Patchy freezing drizzle is also possible. Accordingly, motorists
are urged to plan for extra time to reach their destination
Friday morning.
From: Feb 06, 2026 02:45
Until: Feb 06, 2026 09:00
Special Weather Statement
A band of snow will spread across the area this evening resulting
in a coating to a half inch of snow. Immediately behind the snow
there could be a 2 to 3 hour period of freezing drizzle which may
result in slippery travel especially on untreated and elevated
surfaces.
If traveling this evening or overnight use caution and allow for
extra travel time to reach your destination.
