    As of 09:39 this am we have Moderate snowfall, obscured skies and limited visibility.


For the forecast, a Pacific warm front in a Southwest > Southerly  flow aloft will continue through the day followed by a weak upper trough with very light precipitation for  Friday morning. We can expect strong winds and a freezing level hovering around 1800 meters (possibly < to 1400m this afternoon) as a strong wave moves through this afternoon and into the night. The deep low moving in from the south tonight is associated with strong winds.  Guessing 30-40 cm by Friday morning above 1500 meters. The freezing level will drop back down to 1000 meters as the colder air moves in with the trough early Friday morning while the precip event is still active. Some flurries are expected Friday afternoon. Good news for Saturday when a very moist vigorous frontal band pushes through with significant snowfall, possibly 30-40 cm are forecasted by Sunday morning with a FL hovering around 1000 meters > ?. Model runs have been incosistent so not much confidence in the FL. The Pacific storms continue into Sunday and Monday.  

    Considerable moisture for today.


    Southerly mild subtropical air for today.

    Unsettled Friday morning.

    More cloud with flurries Friday afternoon.

    Lows with a brief high Friday morning.
