    Obscured and snowing at 2180 meters.

For the forecast, the cool low pressure system moving in from the Gulf of Alaska has slowed and weakened over our zone. Today will likely be the wettest of the next few days with the FL rising and hovering in the 2000 meter range. The weather for Friday into Saturday will be dependant on how much cloud and precipitation the low will spin at us once it settles in to the South. For now it looks unsettled, with partly to mostly cloudy periods with the chance of light intermittent showers. The air mass for Sunday is looking quite moist, especially in the morning, lets say Sunday could be a moist day with breaks later in the afternoon. The low will continue to bring cool showery weather into early next week, models are not in agreement to what is happening past Sunday. Standby for an update Friday.

    Low is slowly drifting South.

    Certainly some precipitation heading our way, but it feels like the system is weakening.

    Flow for Thursday.

    Expected precipitation for today into tomorrow. Breaks Friday afternoon.

    Looking mostly cloudy for Friday with some sunny breaks.

    Another decent unsettled day for Saturday as well. Rain possible in the evening.

    Looking towards Sunday!

    Breaks on Monday morning with showers slated for the afternoon.
