Mesoscale Discussion 1903

0351 PM CDT Mon Aug 10 2026

Areas affected...Northeast CO...far northwest KS...and portions of
western NE

Concerning...Severe potential...Watch possible 

Valid 102051Z - 102315Z

Probability of Watch Issuance...60 percent

SUMMARY...The risk of severe wind gusts and hail will increase from
west to east during the next few hours. A watch may be needed
relatively soon for parts of the area.

DISCUSSION...Isolated high-based thunderstorms are evolving along a
lee trough extending from the NE Panhandle southward into
northeastern CO, and storm coverage should continue to increase as a
subtle midlevel wave approaches the area from the west (per recent
WV loops). Over the next few hours, this activity will spread
eastward into a a plume of middle/upper 50s dewpoints and steep
deep-layer lapse rates, which are contributing to a moderately
unstable air mass. This, combined with an elongating and mostly
straight hodograph, should support some convective organization/cell
splitting. While severe hail will be possible (especially in the
earlier stages of convective intensification), the primary concern
will be an increasing risk of severe wind gusts with any clustering
that occurs. A watch may be needed relatively soon for parts of the
area.
