WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM NOON TODAY TO MIDNIGHT CST TONIGHT

Accumulating snow starting Monday afternoon and ending mid to late Monday evening is likely to cause significant travel impacts to the Monday PM commute. Expect to encounter snow covered roads and low visibility. Please plan accordingly for needing PLENTY of extra time to reach your destination. Yes that means more than 1-2 minutes extra. Listen, we know you! Try 30-40 minutes extra. Use extreme caution when driving on snow covered roads and in low visibility. Reduce speed and increase your following distance. This means, even if you have a big honking SUV with like 55″ tires in which you need a 6 ft. ladder to climb, you still need to exercise caution. This is no monster truck exhibition.  Regarding snowfall amounts, several inches are expected area wide. A narrower swath of 6″+ amounts is possible, with latest trends suggesting the highest chance of this occurring for areas along and west of I-39 and near the I-88 and I-80 corridors.

Again, we urge you to be cautious during the afternoon commute. If you can leave work or school early, please do so as conditions will deteriorate as we head into the evening hours. 

 

With the extended forecast calling for a cycle of snow during weekend and into next week, we are pressing two advisory buttons now! The CLC (Checkout Line Congestion) and the HHHH (Hostess Ho Ho Hoarders) advisory. Remember there is a cause and effect here. The HHHHs move into the grocery stores causing CLCs. Remember the safety rules, no eye contact and keep all sweets and potato chips in a hard to reach place in your shopping basket. If they strike up a conversation while in line, just agree with everything by smiling and nodding your head occasionally . At all cost avoid politics! Be safe!

The lack of snow over northern IL thus far this winter has been noteworthy, but that could be about to change. A parade of storm systems over the Pacific will ride the jet stream into the northern and eastern U.S. this weekend into next week. These systems will be fast on each other’s heels, with only about a 24 to 36 hour break in between systems. It is too soon to say how many of these systems will directly impact northern IL and northwest IN, but there does appear to be multiple opportunities for snow this weekend through next week.

The advertised active winter weather pattern appears likely to produce another round of accumulating snow Monday afternoon through Monday evening. It’s becoming increasingly likely that the Monday PM commute will be impacted by snow for at least portions of the local area. Fast on the heels of the Monday system, we’re tracking the potential for a larger storm system to bring accumulating snow to parts of Illinois and Indiana Tuesday afternoon through Tuesday night. There is plenty of uncertainty on the track of this storm system and how much, if any, of the local area will be affected, so it is too early to say how much snow, if any, will occur within the local area. Finally, additional rounds of snow are possible in the Wednesday night-Friday timeframe.
