Sunday Night Winter Wx Update

Some school systems are already closing for Monday. Good call!

I’m watching that radar and I’m liking what I see! Snow has really developed well to our northwest and is poised to swing right on into our neck of the woods later tonight. Temps are also falling outside. I’m currently 37 and falling.

The current radar shows snows breaking out across Indiana. That will be moving southeast and toward our area overnight. In addition, snow showers will likely be enhanced by the topography of the plateau, especially with northwest winds hitting our southwest-to-northeast oriented plateau (northwest flow snow).

Snow is developing, temps are falling, and winter weather advisories are in place. Now, we just wait and see what happens!

My confidence is still high that we’ll see 1-2 inches of snow. Some of you may even see more than that, especially if you live in or near Mayland, Monterey, and Jamestown. Snow should continue through most of Monday.

You all have a good night! I’ll be watching for those first flakes later tonight! The winter weather advisory begins at midnight and expires at 6:00 pm Monday. Dare I say you may get a snow day Tuesday too?!

  1. Have a sort of related question. There seems to be an interesting weather phenomena around the Crab Orchard exit for about six miles East. 329 mm to the 336. They have weather events other parts of the county does not. Rains there when rest of county is dry. Most recently, Friday night there were six weather related crashes on I-40 in just over an hour. There were no other crashes in the county. One firefighter said the interstate was an icy slushy mix. A deputy said the road was a solid sheet of ice where he was. Years ago there was a hail event there. For a mile stretch in late March, I think, hail fell on I-40 so hard and suddenly that around two inches of hail covered the road. State had to call out snow plows to push the hailstones that were marble size off the road. I responded. I was in shirt sleeves and the sun was shining here but around the 331 mm there was a blast of cold air. Temp was at least 20 degrees cooler or more. Fogged up my car windows so badly I had to pull off the road and wait about ten minutes for the window to clear. Is it the cut of the road coupled with the suddenly upgrade that causes this? Is it the ghost of Big Foot Spencer delivering a curse? I wonder if this has ever been studied. Any insight?

    1. Great question, Mike. I remember that hailstorm. That was a wild weather day! As for the situation Saturday night, I was worried about that whole precip event. The warm front was much, much slower than expected and I thought it would never cross the plateau. Those situations make me nervous because rain still moves in, regardless of what the warm front decides. As for Crab Orchard, they are sheltered by mountains. That can allow colder air to become trapped in those valleys and it takes much longer to warm up. That can be very dangerous under any circumstances but it makes it especially dangerous when you put an interstate in the valley. It’s something I try to be mindful of. Forecasting for the plateau is challenging enough but then we have all these microclimates scattered around. When the hailstorm hit that area, the cold air from the hail probably got trapped in the valleys in much of the same way, leaving it cooler for a longer period of time. Down in Knoxville, cold air can get trapped in the valley of East TN and cause freezing rain, too. If the south wind can’t blow the cold air out, the cold air just sits in the valley. Thanks again for the question, Mike, and I hope I’ve helped answer it.
