The latest data continues to give growing conficence in a significant winter event with potentially major impacts to a large part of the Midwest starting late Tuesday night but really focused mostly on Wednesday into Wednesday night and early Thursday. Standard caveats apply as the storm is still quite a ways into the future (4 to 5 days out). However, there is enough evidence available to suggest a major winter storm may impact the region the middle of next week.
As you can see in the maps... the most likely area for all snow (or nearly 100% snow) is from northern Missouri into central/northern Illinois. Moderate to heavy snow will be possible in these areas. Further south...including much of the Fox 2 News viewing area (outlined counties) we will definitely see a fair amount of liquid rain on the front end of this system. But the arrival of cold air during the day Wednesday is expected to transition the rain to freezing rain and then sleet and finally snow by Wednesday evening (if not sooner). Moderate to heavy icing followed by moderate to heavy snow and sleet are possible in this zone.
The region from southern Missouri into southern Illinois will start as rain and continue for rain for quite some time. However, current indications are that cold air will eventually change the rain to freezing rain across the red shaded region Wednesday night with significant ice accumulations possible. Then late Wednesday night into Thursday, a change to all snow is possible with several inches of accumulation on top of the ice.
There are obviously still a lot of specifics to nail down this far out. But the most important message is to keep a close eye on the forecast for the middle of next week. No doubt there will be fine tuning and adjustments as the energy gets closer and comes into better focus.
That is a beautiful anti-cyclonically curved outbound jet with us sitting in the ideal right entrance region area. Next frame on this run and that jet has pumped up to 225kts over lakes. Super strong, lots of difluence in the entrance.

I just ran around the subdivision and was kind of surprised by how many tiny patches of snow are still around from the small storm two weeks ago. It was not just next to driveways or where snowmen had been built either, just a few places that don't get a lot of sun.

grizzlebeard: I'll put this here since it rarely rolls over: Please include your location in your profile, or identify your location when posting observations. You saying it is 20 and raining doesn't help if we don't know where you are. That is all.

snowday_lover: So weird.... sun is really out here right now. I just expected it to be full cloud cover by now. Hopefully the clouds move in soon. I'm ready to see what we get down here.
