Tornado watch issued for the Kansas City metropolitan area

A tornado watch has been issued for the Kansas City area and includes northeast Kansas and northwest Missouri.

The watch was issued at 2:25 p.m. Tuesday by the National Weather Service’s Storm Prediction Center in Norman, Okla. It will be in effect until 10 p.m.

The watch includes Atchison, Douglas, Franklin, Johnson, Leavenworth, Miami, Ottawa, Pottawatomie, Shawnee and Wyandotte counties in Kansas.

On the Missouri side, the watch includes Buchanan, Carroll, Cass, Clay, Henry, Holt, Jackson, Johnson, Nodaway, Platte and Ray counties.

Thunderstorms are expected to develop the remainder of the afternoon into this evening. Some storms could become severe, according to the National Weather Service in Pleasant Hill.

Large hail appears to be the primary threat, along with straight-line wind damage and a few possible tornadoes.

The storms could repeatedly track across the same areas through the evening and overnight hours, producing heavy rainfall over locations that have already received significant rainfall since Monday morning, according to the National Weather Service.

A flash-flood watch remains in effect for the region.

Multiple rounds of thunderstorms are expected late Wednesday through Saturday as a very warm and humid air mass interacts with a stationary front.

There could be several periods of strong or severe thunderstorms, but the primary concern will be persistent heavy rainfall.

Several additional inches of rain are likely the remainder of the week, which could lead to significant flooding across the region.
