With Arctic air already in place across the region, an upper-level
storm system will produce a swath of light snow, as it swings
through our region Thursday. The initial band of light snow may
reach the Interstate 64 corridor of southern Illinois just prior
to daybreak Thursday, but the bulk of the accumulating snowfall is
expected in the morning hours.
1 to 2 inches of snow is possible across the Interstate 64
corridor of southern Illinois and southwest Indiana. The snow is
expected to taper off quickly from west to east Thursday
afternoon. Farther south across the region, a half inch or less
is expected, and much of the area may only see a few periods of
flurries.
At this time, considerable uncertainty exists with this storm
system. On the high end, the potential exists for light
accumulations across the entire area, with narrow bands of
enhanced snowfall. On the low end, a very minor adjustment could
result in nothing but flurries across the area. With the cold air
in place, any accumulations would likely create travel
difficulties.
Please stay tuned for the latest forecasts and statements on this
potential winter storm system from the National Weather Service in
Paducah, Kentucky.
