Winter Weather Advisories remain in effect for all of northern Illinois
and south-central Wisconsin through Midnight as the Stateline deals with
another winter storm. This storm, however, dealt more mixed
precipitation in the form of snow, sleet, freezing rain and even just
rain for a time during the afternoon.
Temperatures were key in determining what fell, and where, throughout
much of the morning and afternoon ranging from the upper 20s across
northwest Illinois and southwest Wisconsin, to the mid 30s in Rockford.
Snow and sleet accumulations were minimal throughout the day as many
areas experienced freezing rain, adding up between a tenth of an inch to
two tenths of an inch. The transition over to now all snow has
started, with snow remaining the predominant precipitation type through
the evening.
Winds are beginning to shift around to the north as low pressure moves
into east-central Illinois. The northwest wind shift has pulled in a
little more cold air throughout the atmosphere. This colder air is
causing any mixed precipitation to turn to snow, which will continue
through Midnight. Additional snow accumulations of 1-3 inches will be
likely as heavier bands of snow rotate through the area.
The snow on top of slushy and icy roads will only make conditions
deteriorate further this evening, with slick conditions expected to last
into Saturday morning. If you must head out Friday evening, please
make sure you use caution. Visibility will also be reduced, in some
locations down to a mile, as the snow moves through. Fog will then set
in following the departure of the snow overnight, lasting into Saturday
morning.
