    As of 08:00 Hrs this am we have overcast skies and variable visability.

For the forecast, cooler weak front for today with light showers beginning later this morning into this afternoon in a Southwest flow aloft. The FL will fluctuate between 1700-1500 meters. By early Saturday morning we could see some breaks in the weather with a lowering FL and a Westerly flow aloft. Saturday will start off unsettled (mix of sun and cloud), shifting to showers in the evening with overcast skies.  Sunday the low will bring overcast skies and very light precipitation before a vigorous frontal band arrives on Monday with light to moderate precipitation and a fluctuating FL from 1900-1600 meters. By Tuesday we will back into cooler temperatures and snow into the tree line. Will post again on Monday with a better idea for Tuesday into next weekend. Its been hard lately to figure out exactly what to expect. Lots of inconsistencies in the model runs.

    Unsettled this morning, cloudier later in the morning.

    Large trough off the West Coast will bring cool showery weather before a deluge on Monday.

    Unsettled Friday morning with mostly cloudy skies and showers by the afternoon.

    Unsettled Saturday morning with some cloud moving in for the evening.

    Cold front on Sunday with some very light precipitation.

    Low may deepen to 970 MB by Monday, will send a vigorous frontal band our way

    Moist front for Monday, will continue into Tuesday. FL should drop to as low as 1600 M Tuesday.

Hi Wayne,

I have been following your blog for 3 years now, it’s great, thank for the amazing work!
Skiing in the Duffey yesterday, October 19th, we had some activity. 
Size 1, Sc wind slab avalanche. 30-40cm crown, 3-4 meters width and 15 meters long. Lee aspect, convexity. The photo is not great sorry, but feel free to share it! 

Seems that the wind has been blowing hard and wind slabs are a big thing right now. That one was little but I’m sure there are bigger ones.  Aitor Asurmendi

    Thursday afternoon.
