... High wind watch now in effect from late Saturday night through
* timing... early Sunday morning through Sunday afternoon.
* Winds... northwest 35 to 45 mph with gusts up to 70 mph.
* Impacts... the high winds can blow down large trees... and
damage roofs... small outbuildings... and signs. Sudden wind
gusts can cause drivers to lose control... especially in
lightweight or high profile vehicles. Strong winds can cause
blowing dust... reduced visibility... and flying debris.

Area forecast discussion for western South Dakota and northeastern Wyoming National Weather Service Rapid City South Dakota 206 PM MST Friday Feb 5 2016 Short term...this evening through Sunday night issued at 205 PM MST Friday Feb 5 2016 Potent middle level impulse in the Pacific northwest will quickly advect east across the northern plains this weekend...supporting mild conds Sat...and cooler but very windy conds Sunday. Biggest concern with this system will be strong northwest winds...with a very good setup for widespread 50-70 miles per hour winds across northwest South Dakota sun. Tonight...warm air advection will spread over the region with strong surface pressure falls ensuing. This will support increasing SW winds over NE Wyoming and in the favored northern bh downslope areas...with winds of 20-30 and gusts in the 40s expected there later tonight. Warm air advection /pos-Theta-E will eventually support a band of middle cloud/virga over the area toward dawn over western areas. Sat/sun...positive Theta-E band will shift quickly east across the area...with at most a few sprinkles/flurries possible...certainly not enough to mention in the forecast. Otherwise...surface cold front will enter the area by afternoon...with surface pressure rises and cold air advection advection ensuing across the northwest. Linked wind profiles/moderate mixing/and isallobaric alignment with the ll flow will support good translation of stronger flow to the surface. In addition...geostrophic winds at h925 indicate 70+ knots across northwest South Dakota...which should support surface gusts in excess of 60 knots. Hence...have decided to issue a High Wind Warning across far northwest South Dakota starting Sat afternoon. Stronger flow is not expected over the southern half of the area until Sunday morning and will let the watch ride as this system is forecast to come in about 6 hours earlier...leading to a shift in maximum winds aloft more toward Sun morning as apposed to Sun afternoon. Buffer profiles indicate the potential for 60-70 miles per hour gust at all place in the watch/warning outside of the Black Hills...which seems very reasonable given mixing potentials. Also extended the watch to the Black Hills as concerns over tree falls per Pine beetle kills. Winds of 40-60 miles per hour will be possible in parts of the hills...especially on ridges. Retained a low chance for some light rain or snow across the northern bh and northwest South Dakota Sat evening...although drier profiles certainly Don/T warrant more than slight chance probability of precipitation at this time. A weak upslope signal is present in the northern Black Hills...however lack of appreciable moisture will highly limit any activity. As for temperatures...expect very mild conds Sat with some 50s expected on the South Dakota plains...possibly even a 60 or two depending on cloud cover. Cooler conds are expected sun...with mostly 30s and a few 40s. Long term...Monday through Friday issued at 205 PM MST Friday Feb 5 2016 A large scale ridge builds over the western Continental U.S. On Monday and Tuesday...before shifting east and breaking down by midweek. A weak wave passes through the flow Thursday and then the upper flow becomes more zonal for next weekend. Temperatures will remain cool on Monday but will warm quite a bit for Tuesday and Wednesday. There will be a slight cool down on Thursday...before rebounding for the end of the week. Overall temperatures will be above average for the entire extended forecast period. && Aviation...for the 00z tafs through 00z Saturday evening issued at 205 PM MST Friday Feb 5 2016 VFR conditions expected through the period.
