From GRR:
High confidence in Arctic air outbreak Sunday through at least
the middle part of the following week, but the daily details are
still unclear. Still some suggestion of a synoptic system possibly
developing along the baroclinic zone to our south Saturday
night/Sunday which may lead to some some synoptic snows followed
by lake effect with several more inches possible. However the
latest ECMWF now has quite a bit of sfc ridging moving in early
next week which could limit the lake effect potential. If that
did occur though, winds would be lighter and wind chills would
not be as brutal than if strong westerly flow persists as
suggested by the GFS. Other complicating factor farther out in
terms of daily specifics and additional snow amounts is whether
or not any clipper systems will be dropping in from the northwest.
How's the lake effect snow totals looking like for sunday and monday? NWS mentioned above that it could be limited. I am in kzoo
