Areas affected...Southeastern Montana

Concerning...Severe Thunderstorm Watch 242...

Valid 270018Z - 270215Z

The severe weather threat for Severe Thunderstorm Watch 242
continues.

SUMMARY...Despite some decrease in buoyancy, a modest increase in
shear into Montana may allow for a brief increase in some storm
intensities over the next 1-2 hours.

DISCUSSION...Semi-discrete convection continues to the north into
southeastern Montana. Modest diurnal cooling has already been noted
on recent surface observations. Storms, however, are moving into an
environment with nominally greater shear. Over the next 1-2 hours,
some activity could see a brief uptick in intensity. Large hail and
isolated strong/damaging winds would be a possibility. Unless
greater cold pool organization occurs, storms should steadily
decrease in intensity as further surface stabilization occurs into
the later evening.
