ST. LOUIS, MO (KTVI) - As the big Midwest storm cranks up blizzard conditions across much of Nebraska into Iowa, I continue to monitor the "spring side" of the storm. We've already had a few pockets of downpours with thunder and there will be a few more into Tuesday afternoon.
The line of showers and thunder showers that is currently west of St. Louis will make steady progress to the east and should clear the St. Louis area and the Highway 67 corridor by 2pm at the latest. There may be some gusty winds with the storms and showers as the cross the metro but widespread severe weather is not expected locally. Once that line clears the storm threat will be over.
Further east and southeast of St. Louis there will continue to be a risk of thunderstorms and some isolated severe weather, although it is a very limited risk. Greatest concern will be a few stronger wind gusts. There is only a small risk of a tornado or two. That risk grows as you get closer to the Ohio River, generally southeast of a line from Carbondale to Mount Vernon.
The storm risk for our southern Illinois counties will be over by around 4 or 5pm.
