Check out the winter storm to our south. Mexico and Texas received snow last night. That snow is has spread into Louisiana, Mississippi, and Alabama. Then it streams northeast from there.
This is a significant winter storm for those areas. White and blue represent snow. Red would be sleet and freezing rain. Green would be rain.
.
.
.
Much of the region dipped into the teens last night. One of the colder mornings of the season, thus far.
Here were the temperatures at 8:30 am. Temperatures have risen a couple degrees off the morning lows.
There were some reporting stations that dipped into the 12 to 15 degree range (not shown on this map and earlier in the morning).
.
.
A disturbance will push through the region tonight into Saturday morning. This system will push clouds into our area and a few snow showers or flurries. At this time, it appears unlikely that accumulation will be a concern. I suppose I can’t completely rule out a dusting.
The best chance of snow flurries or snow showers will be over southern Illinois, southwest Indiana, and western Kentucky. The further north and east you travel the more likely you will run into the snowflakes.
Other than that, quiet weather is anticipated through Monday.
Temperatures will slowly rebound into the 40’s on Sunday and perhaps some 50’s on Monday.
Next Week
Here is the 15 day GFS temperature forecast. Highs and lows.
Keep in mind, this is simply a model. This gives you a general idea of what temperatures will be like over the next few days.
The skill of the model is considerably less once you move past day four or five.

For the most part, next week is anticipated to be fairly quiet. We will have a couple of cold fronts and weak clippers to monitor.
One of those systems will arrive on Monday night and Tuesday morning. This will bring gusty winds and perhaps clouds and flurries. A reinforcing shot of cold air, as well.
Here is the Tuesday weather map. Not much going on. Cold.
You can see the light snow to our northeast. That is the disturbance that could bring some clouds and gusty winds into our region.
.
.
Another cold front is possible around Thursday. That will deliver more clouds and perhaps some flurries.
.
Guidance shows another weak system around Saturday of next week.
No significant winter storms are anticipated through next Friday.

Here are my latest snow probability maps.
These graphics show you the % chance of one inch or more of snow and/or accumulating sleet and freezing rain.
Light snow showers or flurries possible Friday night and Saturday morning. A series of weak disturbances next week could mean sporadic snow flurries or snow showers.

We offer regional radars and local city radars – if a radar does not update then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. This will usually fix any problems.
During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.
