Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1032 PM MST Wed Feb 15 2017

.SHORT TERM...(This Evening Through Thursday Night)
Issued at 154 PM MST Wed Feb 15 2017

Upper ridge covers the western CONUS. With high pressure over the
northern plains, skies are mostly sunny. Winds are southwesterly,
and breezy across northeastern WY. Temperatures are rising into
the 50s and 60s.

The upper ridge will gradually move over the central states, with
warm and dry weather continuing, along with mostly sunny skies and
west-southwest surface winds. Near record highs in the 60s and
possibly lower 70s are expected Thursday. Lows tonight and Thursday
night will be mainly in the 30s.

.LONG TERM...(Friday Through Wednesday)
Issued at 154 PM MST Wed Feb 15 2017

Upper ridging with mild and dry weather will continue Friday into
the weekend. A weak wave will pass through southwest flow Friday,
bringing a slight cooldown but continued dry weather.
Temperatures will rise again into Sunday with WAA ahead of the
next upper wave. The ECMWF and GFS show minimal precip as this
wave crosses the region Sunday night into Monday, and the Canadian
is still the outlier with more precip. Warm temps should keep
most of the precip rain. Weak ridging should keep conditions mild
and dry through midweek, and then models are hinting at a return
of wintry weather for the end of next week.

anticipated at this time.
