2:15am Update - The sleet that we received between 11:45 and 1:30am has really kept snowfall amounts in check with 2-4 inches seen so far. (Why we've seen so much sleet remains a mystery to us (and other mets as well)). We are forecasting this storm to transition into a snow maker for the remainder of the morning. An additional 5 or 6 inches will be possible by the time this is done around noon. Total snowfall accumulations will then range from 7-10 inches. A few isolated amounts higher than that are possible if we get thundersnow to form again. -ES

8:25pm - There haven't been too many reports of thunder with this batch of precip moving in from the southwest. It's not completely snow (as FutureTrack indicates). Precip will likely be freezing rain/sleet as it begins for Whiteside, Lee, southern Carroll, and southwestern Ogle Co. We're still expecting all snow for the US20 corridor (including Rockford). Will stay with going forecast. -ES7:55pm - Moderate freezing rain has been reported within the past few minutes in the Moline, Illinois area. It appears there is just enough warm air aloft to melt the snowflakes on their way down to the surface. What is amazing with this is the fact that temperatures are only in the teens. We will be closely monitoring this trend as it creeps into Whiteside County within the next few minutes. Should we continue seeing the rain/icing reports come in we may be in for a more dire situation at the onset of this winter storm. -ES
6:55pm - The Storm Prediction Center has issued a mesoscale discussion concerning the developing intense precipitation. It increases my thinking that somebody will see thundersnow within the next few hours!4:15pm - I just completed the evening forecast package. I believe we'll see some flurries or light snow develop before 10pm with the real, accumulating snow increasing greatly after midnight. Areas of thunder seem likely with some of the heavier bands. Latest guidance suggests the biggest accumulations will be from Freeport, through Rockford, over to Harvard where some 12-14 inch reports will be possible. All other areas will be in the 6-12 inch range. To reiterate: Heavy snow is expected after midnight and before noon Friday. Significant blowing and drifting is possible making for impossible driving conditions. All unnecessary driving should be completed by this evening with only emergency travel for much of the day Friday. This event will end during the afternoon hours of Friday with additional light snow/flurries accumulating up to an inch from Friday afternoon through Saturday afternoon. An additional 3-6 inches of snow is possible for late-Saturday into Sunday. Near white-out conditions may occur at that time...obviously will take these storms one at a time. -ES
3:00pm - Checking the progress of this winter storm we find a few interesting things. First, it appears that the most intense snow will come after midnight. A precip-start time will be late-evening (probably after 7pm for Whiteside Co.). Precip will overspread the area from SW to NE with areas around Harvard the last to see the precip tonight.Over the past 24 hours worth of model runs, the intensity forecast has not changed one bit! Our going forecast for 6-12 inches holds for now. We are working on our evening forecast right now. Should there be anything that changes, we'll let you know right here. (Push refresh for the latest blog posts and radar views.)

Hey eric, what are the odds right now of possibly seeing thundersnow. Also, I have to work at 7am tomorrow morning, is there a chance I could still make it to work, or do you think the roads will be too horrendous to even try to make it.
Wow, This is the most insane Winter Weather Wave-Train we have seen since December 2000. If this keeps up we could beat out Dec-00 for most snow in the month ever, look at the extended -PNA trof into the midwest/plains, and it's not going away any time soon. We have Pac Storms, Clippers, Ideal Jet Position, and an open transport of moisture from the GOM. Nothing Short of an amazing pattern. Look at the 2 storms after this blockbuster, we could see pretty high snow ratio's even if we get limited QPF. The 13 Weather Team is going to be extremely busy until Christmas. I will be watching.....
The Chicago NWS said theres a chance of some thundersnow
I am just worried about the morning commute, although I have a very good feeling it will not be good at all.
I love this weather blog thing...it helps satisfy the wierd weather obsession I have. The constant updates really hit the spot. THANKS!
Holy Cow!
Just looked at your snow graphic on the right-- I know you're very busy, but Dubuque will see 13 inches of snow or even... more?
That is absolutely incredible. Galena is forecast as 13.0" of snow... and it is not even in that 'pink' shading. How much snow does the pink shading represent?
That is an incredible amount of snow.
I was having my doubts that this was going to be a typical winter storm, giving us 7, 8, maybe 9 inches of snow... But 13, 14, maybe 15-16 inches of HEAVY, WET snow? Wow.
I know the potential of thundersnow is there, but just how likely is it appearing?
I will say this much, since this blog has been going and since I can remember snowstorms, I don't think I have ever seen on 7 day outlook 3 winter storms. I am really starting to wonder with this update if I would have a remote chance of getting into work tomorrow morning. Also eric, will the chat be going later on tonight.
Because this is a short duration storm (12 hours) I feel that the 6-8 will be likely for all of the area. The stripe of heaviest snow will be along US20. Will upload the new snowfall graphic shortly (I just moved the 12"+ amount south by about 10 miles). -ES
Good Evening All..I am home..settled in and ready for this big snow event..will be keeping up with the blog tonight and tomorrow with all of the updates from Eric, Justin and Adam. What a great weather team we have at WREX. Hope anyone who has to venture out this evening or tomorrow drives safely.
I know I am going to get up about 6am and get on this blog to see how road conditions are and decide whether to go to work or not.
Eric,any chance the chat will open later tonight as this storm approaches.
Live Chat, Live Chat, Live Chat...
The crowd chanted.
Just kidding.
But, I do think it is crazy that this storm could give some areas one-third of their average annual snowfall, and WINTER HASN'T BEGUN YET. :)
Wow so belvidere and rockford could get hit pretty bad. i think its a good idea to have a live chat,, or at least sometime tonight whenever you have time. thanks WREX for all the updates!!!
will there be any breaks in this storm?
There will be a chat sometime after I get into work... just woke up from a recharging nap. Getting ready to be in this for the long haul...
are you still predicting 10-12 inches for rockford and belvidere? or will this become an ice/steet event more than snow??
Hi guys,
I am snug in the house with my dogs and a delicious hot chocolate. Telecommuting tomorrow. Ready for this snow, or at least as ready as I'll ever be.
Since I know you guys will be wanting snow reports, I got my primitive little snow measuring device ready (it helps to put it out a few hours before it starts snowing so that it is the same temp as the ground by the time the snow starts). It is a piece of flat plywood that I can put on top of already existing snow ... that way when I stick a ruler (or yardstick!) down as far as it will go after its done snowing and it hits the plywood, I know it is only measuring snow that fell since I put the plywood out. Primitive maybe, but it works for me.
Now I will just curl up with my dogs and that hot chocolate and contemplate the joys of sturdy walls and central heat (and maybe sleep a little) until its time to go out and start shoveling.
Thanks for all you do ... I really do think the 13 Weather Team delivers the very best weather info in the stateline area... and it is appreciated!
So is what we see on futuretrack going to be the big show. Looks like it is right on our doorstep.
I am going to stay up as long as I can. What time should chat be going.
I can confirm the sleet here in Lee County..I can here it against the window..
