Yet another active and relatively widespread severe weather day is likely across portions of the southern plains to Midwest today and tonight.  The system will move east-northeastward over the southern Rockies to the southern Plains and Ozarks...with severe thunderstorms increasingly likely by this afternoon and tonight.  

Showers and thunderstorms will persist across extreme southeastern Kansas and the Missouri Ozarks through sunrise.
The most numerous thunderstorm activity will occur from the Pittsburg and Columbus, Kansas areas...east towards Lamar and into the Stockton Lake region.

  Frequent lightning and torrential rainfall will be the main  impacts from this activity...although a few storms may produce hail up to the size of dimes.

  Rainfall rates of one to two inches per hour will occur with some of these storms...which will lead to a risk of flash flooding. The greatest risk for flash flooding will occur along and north of the Interstate 44 corridor.

 The risk of severe weather and flooding will again occur from  Monday afternoon into early Tuesday morning...and impact the entire outlook area. Thunderstorms and the potential for severe  weather may persist through the day Tuesday as well.

  All modes of severe weather will be possible later Monday into early Tuesday including large hail to the size of golf balls...damaging winds in excess of 60 mph...and tornadoes.

  In addition...multiple rounds of thunderstorms may result in heavy rainfall and flooding.
Development of supercell storms is likely, though mid-evening.  Very large hail and tornadoes are possible with supercells with development of into the Ozarks by late evening and overnight Monday.  Damaging wind potential will likely increase this evening.
