.SHORT TERM...for northeast Montana...tonight through Mon...

The energetic upper low that brought severe thunderstorms Friday
and strong northwest winds with scattered showers today to
Northeast Montana moves farther east into Manitoba this evening.
This movement will begin to diminish its affects tonight on
the local area. Wind will diminish enough to expire the wind
advisory over Fort peck Lake this evening. Showers should taper
off too.

Sunday: While ridging begins to build up over the West, the back
side of the departing trough will rotate wraparound scattered rain
showers over the mainly northern areas. Northwest winds will
continue on the brisk side, continuing the cooler than normal
feel. Except for areas near the Idaho and Wyoming borders, the hot
desert air will be held at bay mainly south of Montana.

Monday: The western ridge continues to build up and amplify,
nudging the ridge axis over the Divide. Temperatures will return
to near normal and winds will become light, for a return to
summery conditions.

.LONG TERM...Mon night through Sat...

Lowered pops slightly early in the period mainly for late Tuesday
as much of the shower/tstorm activity looks to be well to our
southeast. Rest of forecast looked good. TFJ

Previous Discussion... 
Upper low currently moving across Montana will reach eastern
Canada by the beginning of the extended period on Monday night. To
the west, another low has settled over the Gulf of Alaska. With
little movement expected of the two lows, an upper ridge will be
building into the northern Rockies over the next week.

Hot air in the desert southwest will be pulled north across the
Great Basin as the ridge builds. However northwest flow aloft into
the northern Plains will keep the hottest air to the southwest.
Moisture and weak disturbances sliding out of Canada will have the
potential to produce thunderstorms on most days next week. Ebert
