    As of 07:00 Hours we have overcast skies, variable visibility and it is snowing lightly.


For the forecast, a series of fronts (short wave troughs) will continue to influence the pattern in our area until Monday evening. Moderate precipitation is expected early this morning as a trough moves through in a strong Southwesterly flow aloft, with Freezing levels around 1700 meters, possibly dropping to 1400 meters by this evening. There may be a lull in the precip this morning into this afternoon before heavy precip begins again this evening. Moderate to strong winds are forecasted for the alpine.  Moderate precip rates are expected Sunday morning, with another lull Sunday afternoon then light precip expected for Sunday evening. The FL should hover in the 1500 meter mark through this time period.  Monday will see very little precip with cloudy conditions as we finally begin to dry out from this wet period. An upper level ridge will begin to build for Tuesday with mostly cloudy conditions and strengthen for Wednesday into Thursday with unsettled conditions. The air mass will remain fairly warm with the FL possibly being as high as 2000 meters on Wednesday. More on that later. Guesstimates: 20-30 cm by Sunday morning above 1400 meters, 10-12 cm by Monday morning, Trace to 3 cm by Tuesday morning.




   Flow until Tuesday, high pressure builds for Tuesday.

    Moisture expected for today.

    Low will move down the coast on Sunday.

    Not a good year for Atmospheric Rivers, I believe this is the fourth this season.

    Cooling off slightly later today.

   Brunt of the precipitation is South, but we are seeing our fair share!! Should see a lull this afternoon.

Saw the signs up at Shames today at a couple different backcountry gates.  Over 70cm of storm is making for some incredible conditions today and some happy skiers.  Sc Sz 1.5 on steep convex roll and heavy sluffing in the trees.
