MJO wave looks to propagate into phase 8 and then into 1 and 2. After the relaxation in the pattern for the beginning of next week we should see a return to a deep trough centred in the great lakes/upper midwest( a little further west then our current one). A tongue of cold will extend from the prairies into eastern quebec and ottawa, montreal and toronto will feel the arctic blast yet again. Snowier conditions are likely from february 3-11 as the MJO is favourable and the STJ gets enhanced as BZ migrates northwards. Ridging should resume in the SE with more of a battle ground taking place and more average temperatures dominating after the 10th.
Notice the further east jet stream in the pacific which corresponds with MJO phases 8-2 and promotes an aleutians trough which we are seeing. The GWO supports this as we are seeing very high EAMT values pumping a rockies ridge.
