Weather overnight January 02/03, 2024. YouTube Tips ⓘ
Some areas of slick travel, especially bridges, early Wednesday morning across portions of northern Illinois due to lingering light mist and light freezing drizzle.
Period of flurries and snow showers this afternoon/early evening with little to no accumulation expected.
Period of lake effect snow showers tonight into Thursday morning, primarily across northwestern Indiana where some minor accumulations are possible.
Temperatures continue to hover at, or just below, freezing across the area early this morning. Unfortunately, low clouds and even some areas of very light freezing drizzle have been reported across the area. While impacts from this very light freezing drizzle are expected to remain minor, some slick spots have developed on bridges and overpasses in and around the Rockford area, per calls to the Winnebago Sheriffs office and the Rockford observer. Farther south and east into the Chicago metro area temperatures also remain parked right at 32 degrees with this light drizzle moving across the area. As a result, some patchy slick spots can be expected through daybreak on area bridges and overpasses, along with untreated roads. Since any slick spots are expected to remain patchy for the next few hours this morning we will handle this with an SPS and updated graphic highlighting this message.
Weather Radar in northeast Illinois was clear.

Key Messages:
– Some ares of slick travel early this morning across portions of northern IL due to lingering light mist and light freezing drizzle.
– Period of flurries and snow showers this afternoon/early evening with little to no accumulation expected.
– Period of lake effect snow showers tonight into Thursday morning, primarily across northwestern IN where some minor accumulations are possible.
Temperatures continue to hover at, or just below, freezing across the area early this morning. Unfortunately, low clouds and even some areas of very light freezing drizzle have been reported across the area. While impacts from this very light freezing drizzle are expected to remain minor, some slick spots have developed on bridges and overpasses in and around the Rockford area, per calls to the Winnebago Sheriffs office and the Rockford observer. Farther south and east into the Chicago metro area temperatures also remain parked right at 32 degrees with this light drizzle moving across the area. As a result, some patchy slick spots can be expected through daybreak on area bridges and overpasses, along with untreated roads. Since any slick spots are expected to remain patchy for the next few hours this morning we will handle this with an SPS and updated graphic highlighting this message.
Current thinking is that this drizzle/freezing drizzle threat may begin to wane across the area around, or shortly after, daybreak as a weak surface trough continues to shift southeastward out of the area. This thinking is supported by the fact that upstream observations across southern WI continue to show improving ceilings and visibilities, suggesting that the drizzle threat has already ended north of the WI state line. These improving trends are thus anticipated across our area through the early morning hours.
Another fast moving mid-level impulse, currently shifting southward across the Upper Midwest, is slatted to drop across our area this afternoon. This is expected to foster some afternoon and evening flurries and snow showers across the area as low- level lapse rates steepen and push cloud heights into the DGZ. Little to no accumulation is anticipated, so no travel impacts are expected.
Lake effect snow showers are expected to persist across portions of northwestern IN tonight into early Thursday morning as the flow turns northerly down the lake. These showers are generally expected to remain rather unorganized due to the marginal thermodynamic setup on the lake. However, we may have a couple hour period later this evening into the early overnight hours supportive of some better organized bands of showers as lakeshore convergence maximizes with the arrival of the surface cold front. Accordingly, some minor accumulations up around an inch are plausible across parts of Lake and Porter counties in IN tonight. Otherwise, the lake effect snow showers will dissipate Thursday morning as a surface high approaches the western Great Lakes.
