Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0743 PM CDT Tue Jul 26 2022

Valid 270100Z - 271200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL PLAINS AND MID MISSOURI VALLEY...

...SUMMARY...
Thunderstorms associated with hail and marginally severe wind gusts
will be possible across parts of the central Plains and mid Missouri
Valley this evening.

...Central Plains/Mid Missouri Valley...
Widely spaced thunerstorms are currently ongoing along and just
ahead of a cold front located from northeast Colorado northeastward
into eastern Nebraska. The airmass near the front is moderately
unstable with the RAP showing MLCAPE in the 1500 to 2500 J/kg range.
In addition to the instability, large-scale ascent associated with a
subtle shortwave trough evident on water vapor imagery, will provide
support for continued thunderstorm development this evening. This
co*bined with about 40 knots of 0-6 km shear, sampled by the
Goodland, Kansas WSR-88D VWP, will be sufficient for an isolated
severe threat. In spite of the moderate instability and deep-layer
shear, 500-700 mb lapse rates are not particularly steep. This,
along with warm air aloft should keep any severe threat marginal.
The primary threats will be strong wind gusts and hail.
