(5:00PM - 3/28/20) A brief update regarding the ongoing severe weather threat across the state, into tonight...
As was mentioned in our midday update, areas of showers and t'storms from this morning were more widespread and were going to linger around much longer than previously expected prior to today. We had adjusted severe t'storm probabilities in our midday update today based on observations and guidance available. Since that earlier update, it has become even more clear that a significant cut in coverage and level of severe t'storm probabilities are needed, once again based on observations.
Early day showers, t'storms and cloud covered lingered across a good portion of the state for much of the day, which has hindered destabilization for many areas. However, there will still be the chance for some severe t'storms across portions of the state, into tonight.
Across Southern Illinois, isolated to scattered severe t'storms currently across Arkansas are expected to lift northeastward across the area this evening and early tonight. All modes of severe weather will be possible with any storm that becomes severe. Further north, there have been a few t'storms that have recently become severe across Western Illinois. Additional showers and t'storms are expected to develop across Iowa, Northeast Missouri and Western Illinois late this afternoon and into the evening...along and ahead of a front sweeping into the area. This activity will then sweep northeastward across Northern and portions of Central Illinois, into early tonight. Some t'storms will be severe, with all modes of severe weather being possible.
Below is the updated severe t'storm forecast, through tonight.
