Tornado watch issued for 3 states as multiday severe weather, flooding threats begin to unfold

Yet again, another round of severe weather is set to threaten the central U.S. with damaging winds, large hail and tornadoes starting late Tuesday and continuing through Thursday.Simultaneously, a significant risk of extreme flash flooding is growing for the Mississippi and Ohio valleys this week, where some areas could see nearly a foot of rain.The FOX Forecast Center said a strong storm system is strengthening over the western U.S., which will send a cold front and warm front into the central Plains and Midwest.

Severe thunderstorms are expected to develop by Tuesday evening from Texas to Illinois.Weather alerts have been issued in the central U.S.as forecasters watch for storms to develop through Tuesday evening.

Here is a look at the latest radar, warnings and watches.While storms have struggled to form during the day Tuesday due to a strong “cap” – an atmospheric lid that inhibits thunderstorm development – a few isolated storms could develop along the dryline in Oklahoma and Texas, bringing a low chance for hail or strong wind gusts.The National Weather Service’s Storm Prediction Center (SPC) expanded Tuesday’s Level 3 out of 5 risk zone to include the Kansas City metro area and adjacent portions of western Missouri, central and eastern Kansas and central Oklahoma.After sunset, the severe weather threat will increase as storms form along and north of a warm front lifting across Kansas and Missouri.While there is some uncertainty about storm coverage farther south along the cold front, any storms that develop could bring very large hail, damaging winds and tornadoes, some of which could be strong (EF-2 or higher).A significant severe weather threat is anticipated Wednesday, stretching from Lower Michigan and the Ohio Valley southwestward through the mid-South and southern Plains, the FOX Forecast Center said.Storms are likely to be ongoing or developing early in the day from Wisconsin to Oklahoma...
