.DISCUSSION...
Update:

Strong to severe thunderstorms have formed over western and
central portions of Montana and are tracking east. They are
eventually expected to evolve into lines and possibly bowing
segments overnight, leading to damaging wind concerns as well as
large hail, heavy rain, and frequent lightning. A Severe
Thunderstorm Watch is in effect until 3 AM MDT Saturday which
includes all of NE Montana.

Previous Discussion:

Fairly straight-forward forecast. Expecting strong to severe
thunderstorms later this evening and through tonight, approaching
from the southwest. SPC will likely treat the threat as a multi-
staged event: west first then us later in the east. Storms will
easily linger into Saturday morning in our eastern zones.

Saturday, the upper level trough finally begins to move eastward,
moving the threat of severe thunderstorms more toward North
Dakota.

By Sunday, a cold front will bring some much-needed relief as the
main forcing and energy for severe storms push more into the
Dakotas.

Next focus will be next week's high temperatures climbing into the
triple digits.
