Thur-Fri, April 16-17th Snow Event Update #2

(9:45PM - 4/15/20) A storm system set to move through the region Thursday into Friday, will bring yet another late season accumulating snowfall to portions of the state.

Once again there no significant changes are needed with this update, as going forecast continues to be on track.

While a few rain/snow showers will be possible into Western Illinois Thursday morning into early afternoon, the main focus will be later... Snow is expected to move into Western Illinois Thursday mid to late afternoon. This activity will then quickly spread across Northern and portions of Central Illinois, Thursday evening...then continuing into Friday morning, before ending from west to east across the aforementioned areas early to mid Friday morning. Precipitation will fall as all snow across Northern Illinois, with the rain/snow transition zone setting up across Central Illinois. Periods of moderate to heavy snow will be likely Thursday evening into Thursday night as well, with increased snowfall rates likely during this time as well. Not surprisingly given it's mid-April, temperatures will be marginal, thus meaning the greatest snowfall accumulation will be on colder surfaces.

Final snowfall totals within the main axis will likely range from 2-5", with amounts quickly tapering on either side of this axis. Below is the snowfall forecast for this event.
