.DISCUSSION...
Update:

Look for gusty west winds late this morning through this evening
as boundary layer mixing increases across the region, with the
going Lake Wind Advisory remaining in fine shape. Otherwise, a
weak embedded shortwave in the flow aloft could produce enough
upper level support for an isolated shower in the southeast zones
today or tongith, but most places will remain dry. Maliawco

Deep westerly flow sets up today with strong Pacific jet pushing
across the northern Rockies. Should get enough mixing with the
downslope flow to push winds above 20 mph for much of northeast
Montana for the afternoon and early evening. Lake wind advisory
looks on track.

Slight trof develops begins to dig over the Pacific Northwest
overnight, shifting the flow to the southwest. Front has sagged
into northern Wyoming, but waves moving along this boundary could
produce a occasional showers across southeast Montana over the
next few days. This will also keep temperatures on the cooler side
of normal for late July.

Upper ridge begins to rebuild over the Rockies early next week,
bringing hot and dry weather into eastern Montana through mid-
week. Ebert
