    Clouds began to infiltrate the zone early Monday.

    Green Lake early Monday morning.

    15:00 Hours, cloudy but still sunny enough for a nice day.

  660 meters        -3, Valley Temp, Max Temp Yesterday was +7.1

   As of 07:00 Hours we have clear skies, unlimited visibility with an inversion.

For the forecast, strengthening high pressure will bring sunny conditions to the area today with a Northwest flow aloft. Presently there is a warm mid mountain air mass, but the temperatures in the alpine will warm up with a Freezing Level reaching 3500 meters by this afternoon. The ridge will weaken tomorrow afternoon with a Westerly flow aloft allowing a cold front to pass through the zone into Thursday with cloudy conditions, with very light precipitation, ending sometime Thursday afternoon. The flow will become Northerly again and we can expect unsettled conditions as the strong ridge begins to rebuild. Friday may see some lingering cloud but by Saturday we will be back in the sunshine into mid next week. Freezing levels will fluctuate from 2000 meters Wednesday morning to 1500 meters by Wednesday evening. Day time heating and evening cooling will have the FL at closer to average values for this time of the year. Could drop below 800 meters for early Friday and Saturday mornings. Guesstimates: 1-3 cm by Thursday morning, Trace -2 cm by Thursday afternoon.


    Northerly flow will shift to Westerly by tomorrow.

    Jet Stream continues in its Northerly flow.

    Clear today into Wednesday afternoon.

    Cold from moving onshore Wednesday afternoon.

    Some very light precipitation expected from Wednesday evening into Thursday afternoon.


    Strong High Pressure will dominate from Saturday into early next week.

Hi Wayne,

I was up on the Garibaldi area this past weekend. Here are two photos of some recent slides on the east face of Atwell, and the northeast face of Garibaldi (to the right of the shrund).
