MIDWEST U.S. - 1

Persistent cold conditions continue across Illinois, Iowa, and Indiana with highs rangeing from the 40s to near 50 west and low 40s to mid-30sB0F in the east thru mid-week. Tonight we will see rain increasing across the western cornbelt moving into the eastern cornbelt tomorrow. Winds will become much stronger with increasing wind chill stress on livestock. Livestockbproducers should ensure adequate shelter, bedding, and ventilation to mitigate hypothermia risks for cattle and hogs. Gusty winds up to 54 mph Thursday will exacerbate cold stress and outdoor operations. Scattered rain chances around 60% Wednesday night transitioning to trace snow or flurries Thursday in northern and central areas may lead to minor slippery road conditions, potentially causing delays in grain and feed transportation. Overall the normal to warmer than normal temperature trend is likely to continue thru the Chrismas period into the first of the year.
