Good afternoon guys!
This is my first post over the system that will be coming into our region early this week. In the last 24 hours there has been a huge shift in snowfall totals with this system on the "up" trend. If someone asked be 24 hours ago, I would have said Champaign would get 4-6 from this, now we are possibly going to receive 9-12 from this system. A big change!
We are going to see one minor round of snow with this system and one major round of snow. The minor round of snow will occur Sunday night, which will start after dusk in IL and will mostly move out by daylight from west to east. Generally 1-4 with this round in central and southern IL. Here's a map of the snow at Midnight Monday morning AND the snowfall forecast for Sunday night. Keep in mind, any "Day/night" snowfall forecasts are 12 hour periods. So, Day forecasts are 6am-6pm and night forecasts are 6pm-6am!
Now, for the main round of snow: Monday and Monday Night.
Forecasts are expected to change but this is based off where the situation stands as of now.
There will be a break in snow Monday morning as the first road diminishes and continues to move to the east. The snow will start in extreme Southern IL late Monday morning and will continue to move north throughout the day. Very heavy snow can be expected with this round, especially in Southern and east-central IL.
Below I will have Maps for noon and 6pm Monday as well as a snowfall forecast for Monday.
The heavy snow will continue to move to the northeast. The snow will eventually tapper off from southwest to northeast Monday Night and will be completely out of IL by 6am Tuesday. There's also a lake effect component for the Chicago Lakefront Monday Night so that is also something else to watch for.
Below I will have a Midnight Tuesday morning map, Monday Night forecast, and a TOTAL Snowfall map in general from now until Tuesday. I will have another update Monday Morning!
ALSO, another major system is coming into the Ohio River Valley/Southern App Mountains Wednesday night/Thursday and could bring several inches of snow again to the same areas this system is bringing snow to. Just a heads up!
Thanks for reading! Stay tuned!
