.DISCUSSION...
Showers and thunderstorms have formed and are moving into
northeast Montana faster than expected. Update coming out soon with
this change. TFJ

Previous Discussion...
Upper ridge over eastern Montana with trof pushing through
southern BC. Lee trof strengthening in central Montana with fairly
strong low level jet into eastern Montana. Tight gradient will
remain over eastern Montana for most of the day, before the front
pushes east, and winds strong enough for Lake Wind Advisory as
least over the eastern portion of the lake.

Thunderstorm development is expected along the front as it moves
east today. With forcing from the shortwave, along with
instability from strong boundary layer heating, could see some of
the storms produce gusty winds or near severe hail.

Front moves east overnight, and into North Dakota on Tuesday.
Thunderstorms could restrengthen over the east on Tuesday with
weak instability from cold air advection behind the front.

Ridge begins to rebound to the west on Wednesday with dry weather
and warming temperatures continuing into Thursday. There could be
a few showers near the North Dakota border on Wednesday, with
afternoon instability. On Thursday another trof pushes through the
Pacific Northwest, with frontal system bringing thunderstorms to
Montana Thursday night.

Next weekend features zonal to slightly cyclonic flow for
seasonable temperatures and mostly dry conditions. RAE
