.SHORT TERM...(This Evening Through Tuesday Night)
Issued at 136 PM MST Mon Jan 16 2017

Warm air advection will increase aloft across the area tonight and
at the surface on Tuesday as an upper ridge builds over the
region. Temperatures on Tuesday will vary greatly based on
location but will be warmest over the Black Hills where highs
will be around 50 degrees. Many parts of northeastern Wyoming
should see highs in the 40s. The coolest temperatures will be
located toward northwestern and north central South Dakota where
the snow cover is most extensive and the deepest.

.LONG TERM...(Wednesday Through Monday)
Issued at 136 PM MST Mon Jan 16 2017

Upper ridging will remain across the region Wednesday
and Thursday, bringing the warmest days of the week. Temps are
expected to reach the 40s and 50s...with some upper 50s across
downsloped parts of the northern and eastern foothills. Dry weather
is expected during this period. Cyclonic flow will develop for the
end of the week into the weekend, resulting in cooler temps and
better chances for precip. Even with this trough developing, PoPs
will be minimal, as the best dynamics appear to stay south of the
region. High temperatures will return to the 30s.
