Severe storms are expected to sweep across the Kansas City area Wednesday evening bringing the possibility of damaging straight-line winds in excess of 70 mph and large hail.

A few isolated tornadoes are also possible with the line of storms. If they do develop, the tornadoes are expected to spin up quickly and be short-lived, according to the National Weather Service in Pleasant Hill.

The storms are expected to arrive in the Kansas City area between 7 and 8 p.m., according to the National Weather Service.

In northeastern Kansas and northwestern Missouri, the storms are expected to arrive between 4 and 5 p.m. and between 10 p.m. and midnight in central Missouri.

When the storms move through the Kansas City area, they are expected to be in a line. It's along that line that a few isolated tornadoes could spin up. Straight-line winds as strong as weak tornadoes are possible through the evening.

There's also a concern of flash flooding, especially in the Kansas City metro area, after midnight if thunderstorms repeatedly form over the area. Heavier rain is expected with the stronger storms.

A flash-flood watch has been issued for eastern Kansas and western Missouri, including the entire Kansas City area, from 7 p.m. Wednesday through Thursday evening.

Some areas could receive up to 2 inches of rain in a short period from the initial round of thunderstorms Wednesday. An additional round of thunderstorms also could produce heavy rainfall, adding to the risk of flash flooding overnight and early Thursday.

The threat of flooding remains into Thursday evening as another round of severe storms are possible in the afternoon. These storms, which are expected to be less severe than Wednesday's, could also move across the Kansas City area in a linear fashion.
