.DISCUSSION...

Update:
Surface high pressure has brought mostly clear skies and light
winds to NE Montana this evening. A shortwave trough on SW flow
aloft is currently over SW Montana. That wave will move through
the forecast area during the day on Sunday with a weak frontal
boundary. Some moisture ahead of the wave could bring a few
showers to the southwest part of the forecast area late tonight
and some areas north of the Missouri River Sunday morning and
early afternoon. Will update the forecast this evening for this.

Previous Discussion:
Rest of this afternoon and tonight, forecast area will remain
under clear skies and very little chances for precipitation.
This weather pattern will continue until Sunday morning, before 
an area of low pressure moves mainly south of the region by Sunday
afternoon. As a result, showers and possible thunderstorms are
expected to affect mainly southern Garfield, Prairie, Dawson and
Wibaux Counties. For Monday most area will have a chance for
showers and thunderstorms. Most of next week will be in the wetter
side as another upper trof lifts across the Pacific Northwest. FGC

VFR conditions will prevail across all TAF sites through tonight
and Sunday. Look for mid and high level clouds at times late
tonight and Sunday with isolated showers and thunderstorms. Winds
will be light and variable tonight and Sunday.
