The coldest air of the season to impact Central Illinois this weekend

Weather Blog

Peoria, Ill. – A powerful fall storm will bring big a taste of winter to much of the U.S. and will leave Central Illinois with some of the coldest air we’ve seen so far this season.

The Canadian cold front will drop into the Northern Plains on Wednesday and into the Central Plains on Thursday. Ahead of the front showers and thunderstorms are expected with severe storms possible across parts of Oklahoma, Kansas and Texas. Meanwhile, behind the front, snow and strong winds are expected from Colorado to North Dakota with blizzard-like conditions possible across the Northern Plains.

While a few showers and storms are possible Thursday, the main impacts from the front will be felt across Central Illinois on Friday.

Rain and thunderstorms are expected to spread across the region Thursday night and continue throughout the day on Friday. Given the strength of the system, a few strong to severe storms will be possible but widespread severe weather is not expected at this time. It’s early but rainfall amounts look to range from 1.0″ to 2.0″ west of the Illinois River with lighter amounts further east.

Temperatures will drop significantly once the front moves through, reaching the low to mid-70s by late morning/early afternoon then falling into mid-50s by sunset. As the cold air spreads east, temperatures will drop into the mid to upper 30s by sunrise Saturday with wind chills in the upper 20s and lower 30s.

While these temperatures are cold enough to support the development of frost, the wind is expected to remain gusty from the west-northwest which should limit the development of frost to areas sheltered from the wind. Freezing temperatures are not expected which should spare crops and vegetation from significant damage.
