Forecast Addendum 4/8/2023 - 07:00am

Submitted by nmeyers on Sat, 04/08/2023 - 5:01am
Recent Observations: 
  • Overnight on April 6th into the 7th, a winter storm brought on average 10 to 12 inches of moist/wet snow to the mountains above 5,500 feet
  • Yesterday on Gray Butte, below and near treeline, surprisingly greasy, easily triggered wet loose slides were observed. A supportable crust functioned as a firm sliding surface for the new snow
  • Near and primarily above treeline, the south wind was effectively blowing snow around, loading west, north and east aspects. Small wind slabs and cornices were touchy. Leeward ridgelines held wind slabs up to 2.5 feet thick. Fresh cornices were very touchy, but small and inconsequential. Remaining cornices are large and were unreactive
  • Over the past 24 hours, temperatures have ranged from 23° to 35°. Wind has blow predominantly out of the west, averaging 9 mi/hr with gusts to 30 mi/hr. There are 208 inches of snow on the ground, with no new snow
Mountain Weather: 

A quiet day in the weather world. We are under a weak ridge of high pressure, which will result in partly cloudy skies and mild weather. Temperatures will climb above freezing near treeline. South/southwest wind will remain light at lower elevations. Over higher terrain, expect moderate wind speeds.
