Coldest air of the season arrives behind Wednesday's cold front

Similar to Monday, the day is beginning with a round of dense freezing fog. Visibility for a few, such as Janesville and Sterling, are registering at a mile or less so please, travel with caution. 

 

 

  

On the flip side, today features a small break from the snow chances as of late. A weak area of high pressure slides into southern Illinois this afternoon, keeping conditions dry for our Tuesday. This may even result in some sunshine. However, surface temperatures will remain in the low to possibly mid 20s. 

 

  

Winds are expected to pick up overnight as our next cold front approaches from the northwest. This will allow temperatures to gradually rise into Wednesday morning, eventually leaving us with highs in the low 30s. Now, if you are tired of the snow, I'm sorry to say a scattered batch of snow showers will tag along with Wednesday's frontal passage. The best chance for any snow will be during the morning hours. However, this chance will not be as widespread and long-lasting as the previous two opportunities.  

The bigger headline with Wednesday cold front will be the dose of cold air that follows. This will be the coldest air of the season thus far.
 

 

 

Surface temperatures are expected to plummet into Thursday, landing below the 0° mark. Thursday's cold start will pave the way for a well-below average afternoon, with highs only climbing to 11°. The last time high temperatures failed to reach the 20° mark was February 19th, 286 days ago. Temperatures drop below zero Thursday night, though we should wind up back in the 20s by Friday.
