...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER WESTERN AND
CENTRAL MONTANA...AND PARTS OF THE CENTRAL HIGH PLAINS AND SOUTHERN PLAINS...

...SUMMARY...
A few storms may produce marginal hail or strong gusts from eastern
New Mexico and western Texas across Oklahoma and toward northern
Louisiana on Friday. A few strong to severe storms may also occur
across western Montana with gusty winds and marginal hail. Isolated
damaging wind gusts are also possible across portions of the central
High Plains.

...MT...

An upper low will weaken as it moves from the Great Basin to the
central Rockies, with cool temperatures aloft persisting over much
of the region. A surface trough will deepen over central MT with a
cold front moving across ID and into western MT. Daytime heating and
steepening lapse rates may aid wind gust potential as storms develop
late in the day from western into central MT. Relatively strong
upper-level winds will elongate hodographs, and may support cells
producing marginal hail.

...Central High Plains...

Low-level moisture will spread westward into northern CO and eastern
WY as a low pressure trough develops from MT into eastern CO during
the afternoon. Steep lapse rates and 50s F dewpoints will result in
perhaps 1000 J/kg MUCAPE supporting storms forming from southeast WY
into the Front Range. These storms may produce strong to locally
severe outflow winds.

...Southern Plains...

An upper-level jet of 50-70 kt will move into southern NM and
western TX, though midlevel winds will be at or below 30 kt. Strong
heating will occur over the region while southeast surface winds
maintain moisture influx. Storms should form during the afternoon
from eastern NM and spread across western TX and perhaps into
southwest KS. Cool midlevel temperatures may support marginal hail,
though gusty outflow winds will be the most common threat.
Additionally, a few storms may occur farther east from OK into
northeast TX, AR and LA where dewpoints and instability will be
greater. Any storms that can form within the uncapped air mass would
likely move southeastward with isolated strong gust potential.
