Phil Posted March 21, 2018 Report Share Posted March 21, 2018 You need to wipe your camera clean. I can’t see your snow.Lol. I would, but it’s on my ice-covered roof. And FWIW, it’s still freezing rain here. Got 1” of bonus snow/sleet earlier, but the ULL won’t capture the surface low for a few hours.

snow_wizard Posted March 21, 2018 Report Share Posted March 21, 2018 1954 is coming up as an analog on pretty much every GFS run now. That is highly significant when you consider the historic cold we saw in the spring and summer of that year. It will be interesting to see how this all plays out. Quote Death To Warm Anomalies!

TT-SEA Posted March 21, 2018 Report Share Posted March 21, 2018 That’s not how analogs work. The CPC analogs from the GFS runs are based on the pattern that the GFS shows beyond day 7. If the pattern is wrong then the list of analog years that it generates from that run will not be meaningful either. But even if the pattern is correct and the list of analog years from that pattern are correct... that does not mean it will continue to follow one of those years for 6 months. One year will often match many different years at single points in time but none of them in total.

Ironically... the ECMWF did show it at that time and I said that it was probably its SW cut off bias coming into play that allowed the system and cold air to come in from the north and it was unlikely to happen.

But I remember that the 12Z Euro on the 13th, the run in question, showed a ridiculous looking cutoff pattern at day 10, with cold air to our northeast and a huge trough off the California coast, with us in no-man's land in between (that day is easy to remember since I actually looked at the run while waiting for the ferry from Port Townsend to Whidbey Island ). In reality we will have a large, consolidated trough moving into the NW this Friday, on what would have been day 10. Quote Link to comment Share on other sites More sharing options...

I also said... live by the sword and die by the sword that day in reference to needing its bias to actually be right this time to the get cold air. It worked out though! I was wrong.
