The National Weather Service Forecasts-

TODAY...MOSTLY CLOUDY. HIGHS AROUND 46. LIGHT WINDS BECOMING
SOUTHEAST AROUND 10 MPH IN THE AFTERNOON.

TONIGHT...RAIN DEVELOPING DURING THE EVENING. LOWS AROUND 35.
SOUTHEAST WIND TO 15 MPH.

FRIDAY...RAIN. SNOW LEVEL 1200 FEET IN THE MORNING. HIGHS AROUND 44. SOUTHEAST WIND 10 TO 20 MPH.

FRIDAY NIGHT...RAIN SHOWERS. LOWS AROUND 35. SOUTHEAST WIND
10 MPH.

With cloudy conditions, no new snow in the last few days, no measurable precip in the forecast, no notable winds, and temperatures holding consistant with yesterday avalanche danger is LOW at this time.

If we see much direct sunlight look to see snow falling off of trees and rocks starting point release avalanches in steeper longer open pitches. Yet the forecast is for cloudy conditions.

Tip:

Metamorphism:

From the instant snow hits the ground, it begins an endless process of metamorphism. No commonly-occurring substance in nature undergoes such dramatic and rapid changes because snow exists near its ?triple point?, meaning that solid, liquid and vapor phases all exist at the same time. In other words, small, subtle changes in temperature, pressure, humidity and temperature gradient can have a dramatic effect on the type of snow crystal that forms. This makes snow one of the most complex and changeable substances on Earth.
