Mesoscale Discussion 1972

1113 PM CDT Wed Aug 21 2024

Areas affected...eastern Montana/western North Dakota

Concerning...Severe Thunderstorm Watch 643...

Valid 220413Z - 220545Z

The severe weather threat for Severe Thunderstorm Watch 643
continues.

SUMMARY...Severe threat continues to gradually diminish across
eastern Montana/WW 643.

DISCUSSION...Over the last couple of hours, a noted/gradual decrease
in convective coverage -- and particularly intensity -- has
occurred, as the low-level airmass gradually stabilizes.  While
convection will likely linger over the next couple of hours,
including a stronger storm or two at times capable of producing
marginally severe hail and/or wind, new WW issuance is not
anticipated.  As storms move eastward into North Dakota with time,
WW 643 will likely be able to be cancelled prior to its scheduled
22/07Z expiration.
