...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL AND NORTHERN PLAINS...
...SUMMARY...
Thunderstorms with isolated severe gusts and hail will be possible
across parts of the central and northern Plains this evening into
tonight.
...Central and Northern Plains...
Water vapor imagery shows a mid-level low over the northern Rockies,
with cyclonic southwesterly flow located from the Desert Southwest
into the northern Plains. At the surface, a north-to-south oriented
trough is present across the High Plains. Isolated to scattered
thunderstorms are ongoing to the east of the trough from northwest
Nebraska into west-central South Dakota. Additional storms are
ongoing in northeastern Montana to the west of a surface low. As the
low-level jet strengthens across the region tonight, continued
thunderstorm development is expected. A hail and wind-damage threat
will be possible along and near an axis of weak instability from
west-central Nebraska into far southern North Dakota. A wind-damage
threat will also be possible with storms currently ongoing in
northeast Montana.
