For the forecast, the low to our South is still churning some high scattered cloud into our area early this morning in a Southerly flow aloft. The high will strengthen throughout the day bringing sunny conditions through Thursday with freezing levels rising each day topping out at 2000+ meters by Thursday afternoon. A vigorous cold front moves onshore Friday afternoon with moderate to heavy precipitation, strong winds in the alpine and freezing levels dropping to the valley floor Friday night. The front will also bring light to moderate precipitation to the mountains on Saturday with the FL rising to 900 meters during the day and dropping to the valley by Saturday evening in a Westerly flow. At this time Sunday may be unsettled but some models have another cold front moving into the area early next week with slightly warmer temperatures pre front and cooler temperatures post front. More on that as we get closer and there is better agreement in the models. Guesstimates: 20-25 cm by Saturday morning, 10-15 cm by Sunday morning. Winter is back!!
Low slowed down and is still off the Coast of Oregon.
High scattered cloud early Tuesday morning, possible convective cloud development later today.
High pressure strengthens during the day.
Sunny weather for the next couple of days with warm temperatures.
Thursday with the cold front approaching.
Cold front arrives Friday afternoon into Saturday.
