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

Scattered snow showers will continue across southeastern Montana
into the early evening as a trough axis continues to push across
eastern Montana. Winds this afternoon and evening will be gusty,
especially around Livingston, but should only gust as high as 40
to 45 mph. Once the wave moves past expect a brief period of
quiet weather across the area overnight ahead of the wave moving
off the Pacific. The majority of the the energy and moisture still
looks be north of the area. As this wave moves across the area
winds will shift to the northeast. While this will give some
upslope, moisture profiles do not show much of a dendritic growth
zone so have just chance PoPs in pretty much across the area.
Temperatures will be around normal. Reimer

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

Models are in decent agreement through most of the extended
period but diverge by the end of next week into next weekend. A
fast northwest flow aloft will mostly prevail across the forecast
area. A few disturbances within the flow will bring periodic
chances for snow showers across the area. Timing of these
disturbances is difficult this far out given the progressive
nature of the upper flow. As a result, there will be a chance for
snow showers or a rain/snow shower mix almost everyday. As it
stands now, the main weather feature looks to be winds around the
Wednesday timeframe, as well as next Friday/Saturday. Lee-side
troughing looks to develop during these periods but latest
guidance has back off quite a bit on winds for Livingston next
Friday. The 00z run last night had 50kt sustained but has since
backed off to about 30kts for next Friday for Livingston. This is
a ways out and models will no doubt fluctuate with this. Look for
temperatures to be below normal through the period until late next
week when readings may warm slightly above normal. Hooley



Skies will be partly to mostly cloudy this evening and through
the overnight hours. A few snow showers and MVFR conditions will
be possible along the Dakota borders during the evening.
Otherwise, VFR conditions will prevail across the lower
elevations. The mountains and adjacent foothills will be obscured
at times due to snow shower activity. Hooley
