Late December through mid January is the time to watch for the south coast; been thinking that for a while now. The north and interior will get in on the goods first with a cold pool developing as we get into mid month. :thumbup:

Extrapolate the overall pattern depicted there (precursors to a GOA & Aleutian block merger) and it results in a long lasting cold snap for our region. There's that late month sign again!

Models will holm in on a massive arctic blast in the final week of December. Think snow maps depicting 100cm of snow and temps dropping down to -20C. 5 days to the event...a shocking rug pull as the block gets undercut and the cold air slides to the East. We see a day of +2C rain before temps spike to +12C under heavy rain and southerly winds. :dancepine:

Just when all hope is lost...a massive ridge builds over the West Coast for January. We see weeks of frost and tons of fake cold...We do the usual post mortem and bring out thousands of images of forks but February delivers again with days of snow and sleet that accumulate to a slushy few cm! :thumbup:
