   northwest winds and cooler temperatures expected Saturday.

 - Mainly dry conditions are expected through at least Monday with temperatures
   rebounding to as warm as the 80s to around 90 for Monday and

.DISCUSSION...

 - Meteorological Overview:

A series of shortwaves currently moving through northern BC and AB
will dive southeast and carve out a trough across the Canadian
Prairie Provinces this weekend downstream of a building upper level
ridge along the west coast. Breezy west to southwest winds,
primarily across north-central MT with higher gusts along the Rocky
Mountain Front, will diminish some tonight but enough wind persists
to keep minimum temps relatively mild tonight (in the 50s) across
the plains. A cold front associated with the energy moving
through AB drops south through the area Saturday morning, shifting
winds to the north and northwest with a cooler airmass and
surface high pressure sliding south along the Rockies and cooling
temperatures back to near or even slightly below seasonal
averages. While most locations will see a brief period of gusty
north or northwest winds with frontal passage, eastern portions of
north-central MT will see sustained windier conditions through
Saturday afternoon and into the evening in closer proximity to
larger scale troughing moving across SK. Moisture is limited with
this system but northwesterly upslope flow into the central MT
mountains will generate widespread mid level clouds across north-
central MT with a few sprinkles or light showers possible, mainly
near the central MT mountains.

The Canadian trough moves on toward the Great Lakes Sunday allowing
upper level ridging to shift inland Sunday and across the Northern
Rockies and MT Monday. Temperatures rebound back to near or slightly
above seasonal averages Sunday, climbing to well above average
daytime maximum temperatures in the 80s to around 90 at many lower
elevation locations for Monday and Tuesday.

The upper level ridge begins to flatten by late Tuesday with general
agreement among models on a series of fairly weak shortwaves and
associated moisture moving east/northeast across the region in the
more zonal flow that follows through much of next week. Confidence
in the timing and location of these disturbances is still low but
the risk for showers and thunderstorms looks to increase beginning
late Tuesday through much of next week.

 - Forecast Confidence & Scenarios:

There is some potential for the transport of Canadian wildfire smoke
into the area this weekend as steering flow behind the trough moving
across the prairies would put at least central and eastern portions
of the state downstream of fires currently burning in northeast BC and
northwest AB. These areas are under cloud-cover and may be receiving
some precipitation today so there is uncertainty in how much fire
activity and smoke is being produced. Smoke modeling does show
some lower concentration smoke moving into eastern portions of
north-central MT later Saturday into Sunday. Hoenisch

.AVIATION...
06/18Z TAF Period

Expect VFR conditions over the next 24 hours as a surface high
pressure remains over the area. Though this high pressure will
generally keep things tranquil, a passing upper level shortwave
trough will bring a period of increased mid and upper level
clouds, along with a few showers across the higher terrain and
some gusty winds to 35 knots along the Rocky Mountain Front this
afternoon. After 07/12Z increasing low to mid-level clouds will
move in across north-central and central Montana. This will bring
CIGS at KCTB, KHVR, KGTF, and KLWT down to low-VFR through at
least 07/18Z.  Ludwig/thor
