Twice a week the ECMWF model is run out to 32 days and sometimes we can glean some basic info about the very general weather patterns ahead. And sometimes we can’t…
Here are the four weekly averages of 500mb heights, with the anomaly in color. Blue is lower than average and red is above average.
It’s very good the Cascades had a great dumping of snow because the pattern continues to look somewhat pathetic through January as ridging returns.
Week 1 & 2:
You can see ridging through early next week and then some cooler troughs offshore. That should give us at least some sort of weather action later next week. It’s supported by this morning’s ECMWF time series showing temps dropping (in the mountains) later next week:
Week 3 & 4:
That annoying ridging returns overhead and also to the north. The “El Nino” pattern of storms into California doesn’t show up like it did a week or two ago…that’s interesting. I don’t have any other thoughts than that. If these maps are correct, January could be a slow weather month. We’ll see.
