June 2 Severe Weather

Showers and a few embedded thunderstorms are currently working into western Iowa this morning in response to overnight convection in Nebraska. Other storms, some severe, are also moving southeastward from Nebraska into parts of northern Kansas at this time as well. Behind both of these clusters of showers/storms, it is expected to clear off over western and central Nebraska/Kansas. With a lesser extent of clearing currently expected over eastern Nebraska and over Iowa/Missouri. Where the sun can shine, moisture and heating should combine to allow sufficient instability for severe weather later this afternoon. The combination of this instability, and the sufficient shear values will allow for discrete storms capable of large hail, damaging winds, and isolated tornadoes. The best threat currently looks to include a majority of Nebraska, northern Kansas, and potentially far northwestern Missouri.

For the state of Iowa, expect the showers and embedded thunderstorms to continue to slowly move across the state this morning. Leaving behind a fairly stringent cloud deck that will limit daytime heating over much of the state. The lack of heating will only allow for some elevated instability to occur this afternoon, thus do not expect additional thunderstorm development this afternoon. With the primary warm front situation over southern Nebraska, southeastward into portions of Kansas and Missouri, expect thunderstorm development north of the front this evening in Nebraska to work east/southeast into portions of Iowa. These storms tonight may be capable of damaging winds and marginally severe hail, however, given the lack of instability with currently cloud cover lingering for a majority of the day, the severe threat will be fairly limited.

Other updates may be posted later this afternoon if clearing can occur, leaving an increased potential for severe weather across the state.
