Area Forecast Discussion...Updated
National Weather Service Billings MT
612 PM MDT Sat Sep 24 2016

Updated zones to remove expired Winter Weather Advisory for
Bighorns. Adjusted PoP`s while I was at it to increase them for
the early evening from eastern Musselshell to southern Rosebud
where intense band of rain/showers has been stubborn to shift
east. BT


.SHORT TERM...valid for Sun and Mon...

The upper low that has been affecting the area for the past
several days, continues to pivot up into eastern Montana. As it
does, the precip continues to slowly shift to the east. From
Roundup and Billings west the rain has pretty much ended, with the
gustier winds starting to work in. Across the eastern zones and
down into Sheridan Co. the precip will continue into the evening.
Given that the precip will be slow to end, up to another inch of
rainfall over the next 8 to 10 hours.

The cold air aloft in the the Big Horns will continue the snow
above mainly 8000 feet. 6 to 8 inches have already fallen, and
a couple more inches will fall this evening. Will let the Winter
Weather Advisory to continue until 6 PM.

After the precip moves out tonight, winds in the east will
continue to be gusty before reducing early tomorrow morning.
Through the remainder of the extended, ridging will work into the
the northern Rockies which will bring a warming trend and plenty
of sunshine. Reimer

.LONG TERM...valid for Tue...Wed...Thu...Fri...Sat...

Not many changes with the extended forecast on this package.
Ridging in place on Tuesday before a weak impulse moves through
the area. Not expecting rain with that system but ahead of it
some compressional downslope winds should get temperatures into
the 80s in most places. Another weak disturbance on Thursday
brings at least a small chance of rain to the western mountains
and foothills. Upper low approaches the area from the west
bringing the chance for cooler and wetter weather as we head into
the end of the period. Walsh


Rain will continue at MLS and SHR through the afternoon with MVFR
VIS and CIG reductions at time in the heavier rain showers. Winds
will stay gusty out the northwest between 20 and 35 kts at all
sites through the day. Walsh
