Watch now: Snow likely beginning Friday night

  • Updated
  • 0

Snow will return to Central and Southern Illinois Friday evening through the morning hours Saturday. See how conditions will vary across the region in our updated forecast.

After a foggy start to the day for some, temperatures will climb into the mid 30s to low 40s early this afternoon with dry conditions. During the late afternoon though, a rain/snow mix will start to push into Central Illinois. This will quickly transition to all snow after sunset. Light to moderate snow looks to be widespread across the area during the evening hours, with snow showers becoming less numerous after midnight. Snow looks to wrap up during the morning hours Saturday with dry conditions returning to Central Illinois for the afternoon. 

The Bloomington-Normal area looks to receive 1 to 3 inches of snow when it's all said and done. Mattoon also has a forecast of 1 to 3 inches. Decatur could see as little as 1 inch, but as much as 4 inches. Snow totals will be higher to the west where winter weather advisories and winter storm warnings are in effect.

For Southern Illinois, only scattered rain showers are expected during the evening hours. They will become more widespread as the night goes on and eventually will transition to snow from north to south after midnight. The best chance of snow Saturday will be during the morning hours with the last of the snow flurries exiting during the early evening.

If the transition from rain to snow occurs earlier, Carbondale could end up seeing 3 inches of snow. If the transition occurs later, you may only pick up 1 inch.

While road conditions are expected to be significantly worse to the west of us, visibility will still be reduced across Central and Southern Illinois this evening through Saturday morning. Secondary roads in particular could become snow covered. Use caution if driving during this period. Slow down and increase your following distance.
