Update

Most of the new data keeps the 4-6″ amounts in western Illinois & into Missouri. Looks like the 8-10″ amounts will be in Kansas & parts of western Missouri as intense frontogenic banding develops.
In our viewing area, will go with a 1-5″ snow & drop the 6″ amount. It still looks like the heaviest accumulations will be in our far southern areas from Kingman, Crawfordsville & Ladoga to Thorntown, Lebanon, Tipton & Atlanta.
So, 1-2″ will do in the north half with isolated 5″ amounts in the far south. Lafayette/West Lafayette 2-3″ total looks good from the two waves (a bit of lowering from the 3-3.5″ projection yesterday). There is nice frontogenic forcing seen at 20,000 (especially in our far south) so banding features of the snowfall are a good bet, resulting in some pretty variable snowfall amounts in the viewing area (like the last two systems). This is what may bring a 5″ amount in a couple isolated locations.
This would tend to occur with one wave of light snow Monday afternoon-evening, then a break & another wave of snow Monday night-Tuesday morning.
It still looks like brisk, gusty southeast to then north winds of up to 25 mph may accompany most of the snow, resulting in some blowing & drifting. However, the winds will slack off Monday night-Tuesday morning.
Stay tuned for any additional tweaks to the forecast.
Overall, negative NAO/AO pattern with below-normal temperatures & split flow, will result in cold, rather dry pattern to next weekend with just a clipper Friday in northern branch of jet. This may bring 1-2″ of fluffy, dry snow Friday.
Sounds good chad, thanks for the heads up!!!
Chad, do you have a snow map
Chad,
Thanks for the update. Sounds like travel in northern Indiana will not be too difficult.

Sounds like once again Monticello won’t be getting much. Most winters I am happy with that but after the mild winter and scorching summer I am looking forward to lots of snow
Thanks for the info Chad. Didn’t you say that you was going to post your summer forecast on here?
Mad man told you totals dropping see the pattern
I am moving south
More snow for the holiday break!
Susan I’ll trade you places. I live at Kingman and I’m not looking forward to all that snow. But I bet my grandson and little neighbor girl will since they are still young and can play outside.
