Tomer’s Take: Confidence is increasing for a significant Western pattern shift after 1/5. The key snow/cold window for UT/WY/ID/MT/CO is 1/6-1/9 with a two storm combo.
The Northeast might benefit from this Western pattern shift. For now, I’ll assume a perfect (best/worst case) setup and trim forecast in coming days.
My afternoon forecast video update:
