...SIGNIFICANT RAINFALL THROUGH MONDAY...
...SNOW AT HIGH ELEVATIONS SUNDAY NIGHT INTO EARLY MONDAY...

.DISCUSSION...Rain showers with isolated thunderstorms have been
steadily moving across north central Idaho and western Montana
this afternoon. With increasingly unstable conditions expected to
continue through later this evening, further development of
thunderstorms is likely to occur. The best chances will exist
across west central and southwest Montana, as well as most of
Clearwater and Lemhi counties in Idaho. The main concerns continue
to be heavy bursts of rainfall, gusty winds, and lightning. Given
how much cloud cover has been hanging around the region throughout
the day, this may inhibit storms from growing too large or
becoming stronger, but the safest course of action would be to plan
for stormy, quickly-changing conditions.

An unusually cool low pressure system continues to be projected
over the Northern Rockies Sunday and Monday, with widespread
rainfall, very cool daytime temperatures, and even high-elevation
snowfall. Model guidance has had trouble characterizing the path
of the low pressure, as well as depicting the areas to receive the
most precipitation. The latest model runs have favored west
central Montana and portions of southwest Montana for
precipitation amounts, with storm totals in the 1 to 2 inch
range. Snow levels continue to be very low for July during this
event, ranging from 6500 feet along the Continental Divide to 7500
feet along the northern Idaho/Montana border. Hypothermia threat
and low visibility will make for poor outdoor conditions,
particularly at high elevations. Daytime temperatures for Sunday
will be 20+ degrees below the seasonal average.

Scattered showers will continue into Tuesday as an additional
disturbance passes through, with pleasant but still below normal
temperatures. Forecast models lend to moderate confidence that the
middle and latter part of next week will trend toward seasonably
warm temperatures and drier conditions.

&&

.AVIATION...Thunderstorms and heavy bursts of rainfall are likely
through 10/0300Z for KMSO, KBTM, and KSMN today, with isolated
thunder embedded within showers likely for KGPI. Rain will persist
overnight for most locations, particularly across southwest
Montana and central Idaho. By Sunday morning, more widespread,
stratiform rainfall is expected, with high elevation snow causing
persistent, obscured terrain. Ceiling and visibility reductions
will be commonplace throughout the day Sunday into Monday.

.MSO WATCHES/WARNINGS/ADVISORIES...
MT...None.
ID...None.
