...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER THE
NORTHERN HIGH PLAINS REGION...

...SUMMARY...
Isolated strong to severe storms with downburst winds and hail will
be possible later this afternoon and evening across the northern
High Plains region.

...Northern High Plains...

Shortwave trough currently moving through the Pacific Northwest will
crest the northern extension of an upper ridge centered over the
Great Basin and continue through southern Saskatchewan later today.
Associated cold front will reach western MT later this morning and
continue east into central ND through western NE by the end of this
period. Latest observational data show low 60s F dewpoints in
pre-frontal warm sector from eastern MT into the Dakotas. A corridor
of moderate instability (1500-2500 /kg MLCAPE) will evolve this
afternoon as diabatic heating commences and steeper mid-level lapse
rates accompanying an elevated mixed layer advect eastward above the
moist sector. Storms are expected to develop over the higher terrain
of WY during the afternoon and spread eastward into the northern
High Plains. Other storms may develop along the cold front through
eastern MT before moving into western ND. The deeper forcing for
ascent and stronger winds aloft accompanying the shortwave trough
should remain along and north of the international border. However,
veering low-level wind profiles with 30-40 kt effective bulk shear
may support a few storms with mid-level updraft rotation. A few
locally strong to damaging gusts and hail will be possible with
storms that initiate in this environment. However, given expected
isolated to sparse storm coverage, will maintain MRGL risk category
this update.
