It’s Monday afternoon, which means 4 maps (1 for each week) from the ECMWF ensembles. They show the 500mb height and anomaly for each of the next 4 weeks.
Week 1, we already know a big ridge is over us for the next 7 days. No surprise here
Week 2, a change, some wet weather systems and a bit of a stormier pattern. Could end up being on the warm side though…maybe. Not a pattern that would produce much snow below 3,000′. But this could give us some big dumps for the ski areas just in time for MLK weekend around the 18th.
Week 3, more action farther south into California, or what you see could be an average of several lows moving by to the south. Looks like early December’s pattern with ridging developing to our north again while California gets soaked.
Week 4 looks similar to what we have right now. This would say ridging returns at the end of January and early February.
Always remember, this is one run from the ECMWF model. But always fun to look ahead, and also compare with the last two monthly runs.
