So Here I go. Walking out on a limb, and right now it feels real skinny! I've spent the morning pouring over satellite images, computer models upper air soundings and even pilot reports! So now I have to commit-- maybe I should be committed! It looks like Portland, Western Oregon & Southwest Washington are going to flirt with some low elevation snow.

A vigorous area of low pressure is dropping out of the Gulf of Alaska today. The storm is has lots of moisture and a fair amount of cold air. The moisture from todays storm along with lingering cold air over the region will push snow levels down late today and Thursday.

As I've learned in the past, all you have to do in this part of the country is mention the word SNOW and a near panic starts. For 90% of the population I think this is going to be a non-event, just a cold rain will fall. At the higher elevations of the West Hills, some light snow will develop late today or tonight. I'm calling for a snowline between 1000ft to 1500ft.

Take a look at the map below and you can get a general idea where you fall in the rain and snow line.

In the Coast Range, Cascades and The Columbia River Gorge, More than light accumulations can be expected. The Cascades are looking at nearly a foot in the next 30 hours. A snow Advisory will be issued later for the Cascades and the Gorge. Snow levels will remain low through Friday but moisture to produce more snow will limited.

Long term it looks like we're in for a reversal of weather patterns, A milder, windy and wet storm arrives late Sunday, that storm could pack a wallop! Winds to 80mph on the coast may occur. Oh forecasting in the Pacific Northwest in the winter, it's just like riding a roller coaster.
