Pattern is improving but from such a terrible point.
I'm comfortable going ratter for SNE before first day of winter. Some observations on why:
1) Generally: Northern stream is traversing our region when big storms are not nearby. Said differently, snow potential is highest for small disturbances, rain potential is highest for strong disturbances. N to slightly BN happening mostly with dry conditions. AN conditions happening mostly with wet conditions.
2) Generally: The Pacific jet is producing our big storms; and even with -NAO in place, and blocking, sig El Nino conditions are sufficient to overwhelm confluence and the BL with p-type/accumulation issues. Blocking won't flee it will, "strangely" erode.
3) Snow-cover near all time lows by Jan 1; this includes our key cold source regions in Southern Canada.
