Severe Weather Threat: April 22

Another day of severe weather potential across the Plains, with the threat now including portions of the Central Plains (southern Kansas). A warm front currently located just north of the Kansas/Oklahoma border will continue to progress slowly northward today, leading to widespread showers/thunderstorms north of the boundary and clearing skies and destabilization south of the boundary. By this evening the warm front should be located along a line extending from the southwest corner of Nebraska to ~Emporia, KS. Areas just along and south of this boundary will have the potential for severe weather this evening into the early overnight. At this point the best severe weather threat will be along the dryline in western portions of Kansas, Oklahoma and Texas. These areas will have better instability to go along with better convergence along the dryline boundary. Nonetheless, areas of southern Kansas, especially southwest Kansas, will have the potential for severe weather including large hail, isolated tornadoes, and a few damaging wind gusts. As mentioned, areas further west towards the dryline will see the higher risk for severe weather this afternoon/evening.

In addition to the severe weather threat, general showers/thunderstorms north of this boundary should persist through much of the day. These showers/thunderstorms are currently entering the Kansas City Metro and should continue well into the afternoon as the front only slowly progresses them northward. No severe weather threat is expected north of the boundary due to lack of instability.

An additional update is likely tonight to discuss any ongoing severe weather, and tomorrow threat for severe weather which will shift north and east and include the Kansas City Metro! Friday's severe weather threat will include the risks of very large hail, damaging winds and tornadoes...
