    Cloud hung onto the peaks for most of the day.

    By mid morning on Saturday there was some decent light with high clouds and sunny breaks.

    Later in the afternoon the clouds and light precipitation did return.

    As of 07:00 Hours this am we have overcast skies, limited visibility and it is snowing 1 cm per hour.

For the forecast, a slow moving front will bring moderate to heavy precipitation to the area this morning with a freezing level starting at around 1500 meters this morning rising to 1800+ meters this afternoon\ evening in a Southwesterly flow. We may see the precipitation ease by this afternoon depending on the flow, with moderate precipitation this evening.  Precipitation should ease Monday morning then slowly ramp back up in the afternoon\evening with the FL dropping to 1600 meters with the arrival of a cold front. An upper level trough will build for Tuesday into Thursday with mostly cloudy conditions, cooler temperatures and a showery pattern. Weak ridging to our South during this time period will likely bring a few breaks in the mix. FL from Tuesday to Thursday will range from 800 to 1400 meters.
Guesstimates: 20-30 cm above 1700 meters by Monday morning, 18-25 cm above 1600 meters by Tuesday morning, 4-6 cm above 1200 meters by Wednesday morning.
