Peoria, Ill. – Another storm system is bringing accumulating snow to Central Illinois beginning Sunday afternoon and continuing off and on through Monday.

- Widespread accumulations of 1-3 inches appear reasonable, though locally higher amounts further south are possible
- Snow-covered roads and hazardous travel are expected Sunday night through Tuesday morning. Use caution if you have to drive.
Confidence is increasing this weekend over the possibility of accumulating snow in Central Illinois. However, slight model differences in storm timing and strength along with details in how the storm will evolve over time, bring some uncertainty to the snowfall forecast. This storm has the potential to be a two-punch storm with a lull in between bursts of snow showers.
Storm Timeline – As of 5 pm Friday
Sunday Afternoon – Snow begins to develop south of I-74, gradually shifting north across the region by Sunday evening.
Sunday Night – Periods of snow will be possible across the region throughout the night. Snow could taper off for a few hours, or become very light, after midnight.
Monday – Snow will become widespread across Central Illinois as the main system passes through the region. Snow should continue through the late afternoon before coming to an end early Tuesday morning.
The heaviest snow is expected to fall along and south of I-74 with a widespread 2-4 inches expected. Locally higher amounts will be possible closer to I-72 if the precipitation remains as snow, otherwise, snowfall amounts could be a little lighter with periods of freezing rain Sunday night. Further north, lighter accumulations of 1-2 inches are expected.
The finer details are becoming more clear about accumulation, however, a slight track deviation to the north will bring slightly higher amounts to areas from a Galesburg to Pontiac line.
If you plan on traveling you should expect roads to become snow-covered by Sunday night. Travel could become hazardous, particularly south of I-74 on Monday as the main push of the system moves through.
