It's not just LWX with this storm ... EAX (KC) also working with uncertainty:
The overall forecast
remains on track, with the only change being a slight increase
in snow totals for a corridor roughly 30 miles north and south
of US Highway 36 and a slight decrease in snow totals for our
southern counties. This has only increased/tightened the already
large snowfall gradient that has set up over the Interstate 70
corridor and the KC metro, as snowfall could range from a foot
near KCI to only 4" or so across Cass County.
