Severe Storms Possible Tuesday Afternoon/Night Across Central Illinois 02/28/17… 

Isolated showers and thunderstorms are first possible late Monday night through Tuesday morning. Severe weather is not anticipated during this time. Up to one quarter of an inch of rainfall is possible, with higher amounts in thunderstorms.

Severe thunderstorms appear more likely after 2:00 pm Tuesday afternoon, as a low pressure system and associated cold front eject eastward into the area. The Storm Prediction Center (SPC), in Norman, Oklahoma, has parts of Central Illinois in an “Enhanced Risk” (orange) for severe storms late Tuesday afternoon/night. Due to the discrete nature of cells, isolated tornadoes will be possible early in the event–5:00 pm to Midnight–followed by a mainly damaging wind event late overnight Tuesday–10:00 pm to 2:00 am Wednesday. Thunderstorms will entirely diminish by early Wednesday morning (after midnight), and rain showers will continue through Wednesday morning. Ample instability, in general, for this time of year and strong winds blasting aloft will set the stage for an “Enhanced Risk” day in Central Illinois. However, cloud cover throughout most of the day could reduce the overall severe weather threat. Tuesday afternoon is still a great time to have a battery-powered NOAA Weather Radio and the free CI Weather App. Your Local Weather Authority will continue to bring you updates on air and online.
