The combination of dense fog and overnight low temperatures diving towards the upper teens and low twenties will make for another potentially treacherous morning commute Tuesday.
The National Weather Service has issued a Dense Fog Advisory for Benton, Newton and Jasper Counties through 1:00 P.M. ET. While those are the only counties across our region named in that Advisory, visibility may fall below a quarter of a mile throughout our whole viewing area at times tomorrow morning and early afternoon. I wouldn't be surprised to see the Advisory extended to include more of our viewing area before the morning is up.
Complicating the situation, temperatures are expected to fall to their lowest point since Sunday morning; this will likely lead to the refreezing of any standing water on roadways and sidewalks in addition to the likelihood of freezing fog early tomorrow! Be careful Tuesday morning.
I’ve already had a few folks ask me about this, but you may have heard rumblings of a potentially significant winter storm affecting portions of the Midwest late this week. If you haven’t, allow me to bring you up to speed. I’m watching a cold front expected to swing east through the Midwest Thursday and Friday.
Thursday looks mild and rainy, but cold Canadian air flowing southward on the back edge of the front will generate a wintry mixture and snowfall late that night and Friday. There isn’t a whole lot of agreement between models at this time, making pinning down timing and exact snowfall amounts difficult. While it is by no means a foregone conclusion that this potential winter storm will come to fruition, if these trends continue, the possibility will remain. We’ll know more in the next 48 hours.
As for now, let’s focus on the fog and the significant warm-up headed our way. Afternoon highs on Thursday will reach the upper 50s for many of us and possible low 60s for a few. Enjoy the warmth while it lasts though, we’ll fall into the single digits again by early Sunday morning!
