Shifting Pattern and Snow Bullseye For Tetons

Tomer’s Take: The pattern 2/12-2/15 favors PNW/BC/ID/MT/WY. Then the stormtrack shifts south 2/16-2/22 to favor CA/OR/UT/ID/WY/CO. The overlap between both periods is the Teton Range, WY where I’m forecasting 2-3 feet of grand total accumulation. Overall, the pattern continues trending weaker for most locations. What once looked like a major initial storm system 2/15-2/17 now looks weak/fast/ragged.

In the Northeast, the 2/13 storm system continues shifting south, and that pulls snow accumulation out of VT/NH/ME.

Next storm system arrives late 2/15-2/16.
