The past week in Central Illinois has been anything but typical. Temperatures have been consistently 20°-30° above average which is expected to continue through Friday. 

Since February 16th Peoria has seen high temperatures at or above 60°. Since then, Peoria has set four new record high temperatures and two new record “warm” lows. These records also include a tie for a February high temperature of 74° that was set on Monday, February 20th.

Below are some of the records set since February 17th

2/17 – High: 72°         Previous Record: 64° (2011)

2/18 – High: 68°         Previous Record: 63° (1994)

2/20 – High: 74° **     Previous Record: 68° (2016)

         – Warm-Low: 48°         Previous Record: 46° 

2/21 – Warm-Low: 55° **     Previous Record: 46° (1930)

** February Monthly Record

Additional records are expected to be set through the rest of the work week, especially on Wednesday and Thursday. Wednesday’s high temperatures could once again challenge February monthly high temperature of 74°.

A powerful storm system is expected to change the weather pattern for the weekend bringing more seasonal weather and even a threat of snow to Central Illinois.

A storm will move across the Central Plains on Thursday, sending a warm front through Central Illinois Thursday night. Southerly flow behind the front will bring more warm and humid air to Central Illinois allowing showers and thunderstorms to develop, especially north of I-74. 

The chance of storms will increase Thursday night and Friday morning as the area of low pressure inches closer to the region. A powerful jet stream will also be moving in from the west which could allow a few strong storms to develop. The cold front will begin to move through Central Illinois Friday morning which should shift the the greater threat of severe weather east in to Indiana, though a few strong to severe storms will be possible along and east of I-55.  If the front moves in later than expected, the severe weather across Central Illinois could increase.

Temperatures will drop behind the front with weekend high temperatures only reaching the mid to upper 30s. Wrap around moisture will bring a chance of light snow to Central Illinois Friday night and Saturday morning. Another system may bring more snow to Central Illinois on Sunday.

The unsettled weather will continue in to early next week with more showers and storms possible on Monday and Tuesday.
